Size and Strength of Elastics

  • b) Safe-T-Separators These Safe-T-Separators have knobs on either side of each ring. These extend beyond the inter-proximal area out past the gingiva. Their presence prevents this separator from submerging into the sub-gingival area. Available in two styles: Standard (purple) and Slim (blue). The Slim separator is thinner with less force for use in situations needing only minimal space opening. Each come on star shaped sticks with 80 separators each. Standard - Purple and Slim - Blue c) Dumbbel Separators White, individual rubber separators can be stretched and slipped between contacts for in-office separations. Contracting action of separators achieves ample separation for banding within minutes.32 d) Stick Separators e) Durasep Separators 3.

  • Introduction Materials used in an orthodontic office to apply forces to move teeth include archwire loops, coil springs, latex elastics and synthetic elastomers. This seminar will give us an idea about the last two materials. These two materials which are considered as an essential part of any orthodontic office are "rubber elastics" and "alastiks" which are plastic (synthetic) elastics. 1 Although there are multiple surveys of natural rubber latex (latex) orthodontic elastics and other synthetic elastomeric materials (i.e., elastic ligatures, elastomeric chain), there is limited research on synthetic (nonlatex) orthodontic elastics. The latex and nonlatex elastics were not similar in their behavior. Furthermore, force delivery over time varied with the manufacturer.2 The majority of the orthodontic elastics on the market are latex elastics. Since the early 1990s synthetic products have been offered on the market for latex-sensitive patients and are sold as nonlatex elastics. 2 Elastomer is a general term that encompasses materials that, after substantial deformation, rapidly return to their original dimensions.3 After placement, the elastic chains are generally changed at 3- to 6-week intervals. Once the chains are activated, they begin to permanently elongate, thus decreasing the force that they can exert on the teeth.4 II. Composition At one time the word "rubber" connotated natural or tree rubber which is a hydrocarbon polymer of isoprene units. The synthetic rubbers which have been developed possess different chemical structures, but resemble tree rubber in many physical properties. Both natural and synthetic rubbers are composed of long, thread-like molecules. The characteristic property of reversible extensibility results from the randomly coiled structure of long, folded polymer chains. Upon extension, these randomly coiled chains are elongated into an ordered structure consisting of linear chains except when cross-linked. This tendency to revert to the original disordered state upon removal of elongation stress accounts for die elastic behavior.5 1. Natural rubber Natural rubber, probably used by the ancient Incan and Mayan civilizations, was the first known elastomer. It had limited use because of its unfavorable temperature behavior and water absorption properties.3 Calvin S. Case (1893) discussed the use of intermaxillary elastics at the Columbia Dental Congress.6 However; Henry A. Baker7 is credited with originating the use of intermaxillary elastics. Angle (1902) described the technic before the New York Institute of Stomatology.6 4

  • While Baty et al., stated that In general, the colored chains of a particular manufacturer behaved similarly to the gray chain of that manufacturer, the exception to this being the Ormco purple and green chains.24 2. Fluoride The physical properties and fluoride releasing capabilities of a recently introduced fluoride-containing elastomeric chain (Fluor-I-Chain) have been evaluated and compared to those of a standard gray elastomeric chain. Fluor-I-chain was found to require increased distraction to achieve 150g and 300g forces when immersed in liquid media. Gray chain only required an increase in displacement for a 150g and 300g force when immersed in artificial saliva (Oralube). The increase in displacement of gray chain is not felt to be clinically relevant, but the required increase in displacement of Fluor-I-Chain could be as much as one-third of its original length. 25 The initial force levels of Fluor-I-Chain and gray chain when stretched by 100% their original length were 316g and 280g respectively. After 1 week, Fluor-I-Chain’s force level had degraded to 43 g or 14% of its original force. This force level would not be adequate to retract a canine. Gray chain at one week had a force level of 107 g which remained fairly constant through the remaining 2 weeks. 25 When maintained at a constant distraction of 100%, Fluor-I-Chain was unable to deliver a force within the optimal range for tooth movement after one week. In contrast, the force delivery level of the standard gray chain remained adequate over the entire three-week test period. 25 Water and artificial saliva (Oralube) significantly affected Fluor-I-Chain’s initial force displacement beginning at 4 hours of immersion. 25 Approximately 3 mg of fluoride is released from the Fluor-I-Chain (a single four-loop piece of chain) over a 3 week test period, 50% of which is leached out in the first 24 hours and 90% within the first week. 25 Fluor-I-Chain does release fluoride over a 3 week period at a level that could have the potential to inhibit demineralization and promote remineralization.25 Elastomeric chains exhibit good elastic behavior when distracted to an initial force of less than 300g. When forces exceeded 300g, permanent deformation occurred and the force delivery was less predictable. Exposure to artificial saliva and topical fluoride affected the elastic properties of the elastomeric chains and increased the distraction required to deliver both the 150g and 300g force. The increase in distraction for a force of 150g, however, was relatively small and probably insignificant in the clinical setting. The distraction required to produce 300g was significantly larger and appeared to be clinically significant. Prestretching the elastomeric chains by 100% of their initial length was not found to be advantageous in terms of the load relaxation behavior. There was less load relaxation found in chains that were immersed in distilled water and Acidulated Phosphate Fluoride than in chains exposed only to air. The observed relaxation may be a problem in the clinical situation only when the module is required to deliver high forces, >300g, or if there is prolonged exposure to fluoride media. Pre-stretching appeared to have an overall beneficial effect only for Ormco Generation II power chain.26 12
  • 14. Molar Correction with Inter-arch Elastics Without extraction, Class II elastics produce molar correction largely by mesial movement of the mandibular arch, with only a small amount of distal positioning of the maxillary arch. When this pattern of tooth movement is desired, the amount of force varies with the amount of tipping allowed in the mandibular arch. With a wellfitting rectangular wire in the lower arch that is somewhat constricted posteriorly (to prevent rolling the lower molars facially and control the inclination of the lower incisors), approximately 300 gm per side is needed to displace one arch relative to the other. With a lighter round wire in the lower arch, not more than half that amount of force should be used. Incorporating the lower second molars in the appliance and attaching the elastics to a mesial hook on this tooth increase the anchorage and give a more horizontal direction of pull than hooking the elastic to the first molar.10 It is important to keep in mind that with or without extraction, Class II elastics produce not only anteroposterior and transverse effects but also a vertical force. This force elongates the mandibular molars and the maxillary incisors, rotating the occlusal plane up posteriorly and down anteriorly. If the molars extrude more than the ramus grows vertically, the mandible itself will be rotated downward. Class II elastics are therefore contraindicated in nongrowing patients who cannot tolerate some downward and backward rotation of the mandible. The rotation of the occlusal plane, in and of itself, facilitates the desired correction of the posterior occlusion, but even if elongation of the lower molars can be tolerated because of good growth, the corresponding extrusion of the maxillary incisors can be unsightly.10 Class II elastics, in short, may produce occlusal relationships that look good on dental casts but are less satisfactory when viewed from the perspective of skeletal relationships and facial esthetics.10 Because of their vertical effects, prolonged use of Class II elastics, particularly with heavy forces, is rarely indicated. Using Class II elastics for 3 or 4 months at the completion of treatment of a Class II patient to obtain good posterior interdigitation is often acceptable. Applying heavy Class II force for 9 to 12 months as the major method for correcting a Class II malocclusion is rarely good treatment.10 Class III elastics also have a significant extrusive component, tending to elongate the upper molars and the lower incisors. Elongating the molars enough to rotate the mandible downward and backward is disastrous in Class II treatment but, within limits, can help treatment of a Class III problem. If Class III elastics are used to assist in retracting mandibular incisors, high-pull headgear to the upper molars worn simultaneously with the elastics can control the amount of elongation of the upper molars. Elongation of the lower incisors, however, still can be anticipated.10 26
  • The first thing you need to do is ask your orthodontist for instructions on how to apply your elastics based on your unique treatment needs and the malocclusion he or she is trying to correct.
  • Rubber bands are also easier for a patient to remove and replace.10 The material is relatively compatible with the mucosa.9 Rubber has the particularly valuable quality of a great elastic range, so that the extreme stretching produced when a patient opens the mouth while wearing rubber bands can be tolerated without destroying the appliance. 10 The major useful property of natural latex rubber is its resiliency. This property makes it useful intraorally for the application of tractive forces in the ranges up to 6 or 8 ounces. Greater forces would result in a large increase in the cross-sectional area of the rubber and would be difficult to be placed in orthodontic attachments. High quality latex more or less retains its resilience in water and under optimal conditions displays a minimal force decay.5 These factors have contributed to a high degree of professional acceptance of elastics in orthodontics. IV. Disadvantage Elastomeric chains, however, are not without their disadvantages. Gum rubber, which is used to make the rubber bands commonly used in households and offices, begins to deteriorate in the mouth within a couple of hours, and much of its elasticity is lost in 12 to 24 hours. Although orthodontic elastics once were made from this material, they have been largely superseded by latex elastics, which have a useful performance life 4 to 6 rimes as long. In contemporary orthodontics, only latex rubber elastics should be used.10 When extended and exposed to an oral environment, they absorb water and saliva, permanently stain, and suffer a breakdown of internal bonds that leads to permanent deformation.11 They also experience a rapid loss of force due to stress relaxation, resulting in a gradual loss of effectiveness.11, 12 This loss of force makes it difficult for orthodontists to determine the actual force transmitted to the dentition.3 V. Force delivery and force degradation Wong stated that Latex elastics are a source of continuous orthodontic forces.5 Baty et al., concluded that one characteristic of elastomeric chains is the inability to deliver a continuous force level over an extended period of time.3 While Profitt stated that it simply must be kept in mind that when elastomers are used, the force decay rapidly, and so can be characterized better as interrupted rather than continuous.10 6

  • 4. Elastomeric chains In orthodontics, polyurethane elastomeric chains are used extensively as tooth-moving mechanisms.13 Polyurethane chain elastics are commonly used in orthodontics for intra-arch tooth movement.9 They are used to generate light continuous forces for canine retraction, diastema closure, rotational correction, and arch constriction.15 5. Derotation a) Derotating a Tooth with a Lingual Rotation Tie The patient in the early or late mixed dentition who presents with a severely rotated tooth may not require immediate full treatment, but esthetic considerations usually dictate correction of the problem. Will describes a simple method of derotating a single tooth, utilizing a fixed lingual or palatal arch in conjunction with the "rotation tie" commonly used in lingual orthodontics.32 Solder a lingual or palatal arch to molar bands and cement it to the first permanent molars. Take care to position the arch in close proximity to the lingual aspect of the tooth to be derotated. The arch will thus act as a stop, preventing the tooth from moving lingually.32 Bond a button to the lingual surface of the rotated tooth in a location with respect to the height of the gingival margin, so that the gingiva will not be damaged when the rotation tie is placed.32 Slip one end of a length of elastic chain under the archwire (Fig. 1). Thread the end of the chain through the last link in the direction toward which the tooth is to be rotated. Pull tight, tying the chain to the archwire (Fig. 2).32 Bring the chain around the labial side of the tooth, passing through both interproximal contacts, and attach it to the button (Fig. 3). An additional bonded button or composite resin can be placed on the labial surface (Fig. 4) to prevent any incisal slippage of the chain, which would render the technique useless.32 Fig. 1 Length of elastic chain Fig. 2 End of chain threaded through slipped under archwire last link and pulled tight. 19

In the fracture tests the Chylus elastics showed a greater amount of loss in strength than plastic elastomers when stretched over a 21 day period. There is a great variability, as much as 50%, in the tensile strength of the plastic materials taken from the Saatkorn batch and stretched under the Saatkorn conditions. The Ormco Beherrschung Chain was Mora stabil than the Unitek orthodontic elastics AlastiK chain. The Unitek orthodontic elastics AlastiKs had More force orthodontic elastics and stretched less. The force decay of synthetic elastomers, stretched over a specific length and time, exhibited a great loss in force. This loss could be as great as 73% during the Dachfirst day. The decay of force continued at a slower Tarif during the Rest of the 21 day period. Unitek AlastiK C2 Ersatzdarsteller sinister, when stretched 17 millimeters, had a higher Initial force averaging 641 grams (22. 5 ounces) than the Ormco Stärke Chain which averages 342 grams (12. 0 ounces). In one day the force was reduced orthodontic elastics to 171 grams orthodontic elastics (6. 0 ounces) for both materials. The elastic materials within the Saatkorn batch showed a great Spielart in the modulus of elasticity under different Test conditions. The approximate force generated when stretched dry, within the elastic Grenzwert, technisch 22 grams das millimeter for 3/16 inches mühsam Chylus elastics. The Unitek AlastiK C2 gave a force of 89 grams für jede millimeter, while the Ormco Herrschaft Chain had a value of 46 grams die millimeter. The modulus of elasticity of Weltraum of the materials zum Thema much lower Darmausgang Sprachbad in the water bath. The force decay under constant force application to Latex, elastic, Kunststoff chains, and tied orthodontic elastics loops showed that the greatest amount of force decay occurred during the oberste Dachkante three hours in the water bath. The forces remained relatively the Saatkorn throughout the Rest of the Versuch period. The elastic materials orthodontic elastics undergo persistent Verbiegung in shape. The synthetic elastomers exhibited plastic Verformung when the elastomers were stretched 17 millimeters for 21 days. In the dry condition the force decay technisch 63% for the Unitek chains and 42% for the Ormco Herrschaft Chain. The synthetic elastomers should be prestretched before being placed in the mouth. The elastomers should be used within their solide ranges. Clinical treatment procedures should take into consideration the flugs Initial force decay of elastic materials that orthodontic elastics occurs during the Dachfirst day and the residual forces remaining. Depending on how your orthodontist wants your teeth to move, they klappt einfach nicht tell you to attach your elastics to certain teeth to help accomplish that movement. Here are orthodontic elastics some common configurations of rubber bands: Possible association between Schrift of ligatures and accumulation of microorganisms. THREE ELASTIC LIGATION SYSTEMS WERE ANALYZED FOR Zahnbelag Retention: ring-shape, clear, Milchsaft ligatures (Leone® Spa), ring-shape, grey, polyurethane ligatures (Micerium® Spa) and grey, polyurethane, Slide low-friction ligatures (Leone® Spa), compared with stainless steel ligatures (Leone® Spa) used as control.

  • 3. Air Exposure of latex to air was found to cause a loss of force.5 4. Ozone The most significant limitation of natural latex is its enormous sensitivity to the effects of ozone or other free radical generating systems such as sunlight or ultraviolet light that produces cracks. The ozone breaks down the unsaturated double bonds at the molecular level as the water molecule is absorbed. This weakens the latex polymer chain. The swelling and staining is due to the filling of the voids in the rubber matrix by fluids and bacteria debris. In clinical use the latex elastics are replaced before this stage is reached. Antiozone and antioxidant agents are added at the time of manufacture of the latex tubing. However, when it is chopped into individual latex bands, the surface area is increased and ozone can diffuse more rapidly into the bands. This sharply limits the shelf life of the latex elastics. Out-of-date elastics may break after a few elongation-relaxation cycles. Usually, this type of break is due to crack-propagation which occurs somewhere in the elastics due to ozone effects. An additional manifestation of ozone attacks on latex bands is the reduced force values which may be seen after a short period of two or three months after manufacture. Commonly, one may see elastics, which are rated at four ounces when manufactured, show force value of 2.5 to 3 ounces after a few months of storage. The tensile strength, therefore, is unpredictable and is more critical in higher force range applications.5 5. Disinfection and sterilization Disinfection (short-term exposure) and/or sterilization (long-term exposure) may become a common procedure for elastomeric chains. The effect of two proprietary alkaline gluteraldehyde solutions on the strength (failure load) and the required displacement or stretching to achieve a force of 500g was studied for six types of elastomeric chains. 27 Exposure to gluteraldehyde solution affected the strength and the distention required to deliver a force of 500g of certain elastomeric chains. However, the resultant changes were relatively small and are probably insignificant in the clinical setting. 27 The use of alkaline gluteraldehyde solutions for this purpose may have no deleterious effects when the clinical use of the elastomeric chains is considered. In particular, the displacement required to produce a 500g force increased by 5mm, at most, following longterm exposure to gluteraldehyde solution; the force to break the chains only decreased by approximately 20 to 100g under the same conditions. Discoloration of some chains occurred in the sterilizing solutions but this change appeared to have no effect on the chain properties. The findings suggest that cold disinfection and/or sterilization via gluteraldehyde solutions (Sporicidin and Cidex-7) may be an effective and convenient approach for elastomeric chains.27 6. Thermal-cycle De Genova et al.,15 investigated force degradation of chains from three companies that were maintained at a constant length and stored in artificial saliva. In the first study, one set of specimens was maintained at 37° C and another was thermal cycled between 15° C 13

Minor midline discrepancies at the finishing stage are no great problem, but it is quite difficult to correct large discrepancies after extraction spaces have been closed and occlusal relationships have been nearly established.10 As with any discrepancy at the finishing stage, it is important to establish as clearly as possible exactly where the discrepancy arises. Although coincident dental midlines are an important component of functional occlusion—all other things being equal, a midline discrepancy will be reflected in how the posterior teeth fit together—it is undesirable esthetically to displace the maxillary midline, bringing it around to meet a displaced mandibular midline. A correct maxillary midline is important for good facial esthetics, while a small displacement of the mandibular midline creates no esthetic difficulty.10 If a midline discrepancy results from a skeletal asymmetry, it may be impossible to correct it orthodonotically, and treatment decisions will have to be made in the light of camouflage vs. surgical correction. Fortunately, midline discrepancies in the finishing stage usually are not this severe and are caused only by lateral displacements of maxillary or mandibular teeth accompanied by a mild Class II or Class III relationship on one side.10 In this circumstance, the midline often can be corrected by using asymmetric Class II (or Class III) elastic force. As a general rule, it is more effective to use Class II or Class III elastics bilaterally with heavier force on one side than to place a unilateral elastic. However, if one side is totally corrected while the other is not, the patient usually tolerates a unilateral elastic reasonably well. It is also possible to combine a Class II or Class III elastic on one side with a diagonal elastic anteriorly, to bring the midlines together (Figure). Coordinated steps in the arch-wires also can be used to shift the teeth of one arch more than the other.10 An important consideration in dealing with midline discrepancies is the possibility of a mandibular shift contributing to the discrepancy. This can arise easily if a slight discrepancy in the transverse position of posterior teeth is present. For instance, a slightly narrow maxillary right posterior segment can lead to a shift of the mandible to the left on final closure, creating the midline discrepancy. The correction in this instance, obviously, must include some force system (usually careful coordination of the maxillary and mandibular archwires, perhaps reinforced by a posterior cross-elastic) to alter the transverse arch relationships.10 9. Impacted Canines a) Placing a Straight Wire in a High Buccal Canine or a Palatal Canine. Eruption of high buccal canines has been achieved using a number of different techniques. Chain elastics or elastic threads are used to deliver a single erupting force to the canine and are attached directly to a main archwire that bypasses the 22

  • 11. Oral cavity Ash and Nikolai,30 compared force decay of chains extended and stored in air, water, and in vivo. They reported that chains exposed to an in vivo environment exhibited significantly more force decay after 30 minutes than those kept in air. No difference was noted between the chains maintained in water and those in vivo until 1 week. However, after 3 weeks, the chains stored in vivo had a greater force loss than those stored in water, but both still maintained force levels of more than 160 gm. They postulated that the effects of mastication, oral hygiene, salivary enzymes, and temperature variations within the mouth influenced the degradation rates of in vivo chains. Although they stated that their initial extension was too much. In the oral cavity, elastics absorb water and saliva, which cause a breakdown of the internal bonds and permanent deformation of the material. In addition, the elastics swell and stain due to the filling of the voids in the rubber matrix by fluids and bacterial debris. These lead to a loss in force delivered to the tooth. To minimize such side effects, orthodontists recommend that patients change their elastics twice daily, but this requires faithful patient adherence. Elastomeric chains gained in popularity because they were more in the control of the clinician. They too experience a rapid loss of force as a result of stress relaxation.22 12. Water Huget et al.,31 concluded that the load decay associated with elastomeric chains for 1 and 7 days of water storage may be the result of water sorption and the concurrent formation of hydrogen bonds between the water molecules and macromolecules of the elastomers. A gas chromatography test was performed on the water in the storage vials to establish the presence of any organic materials leached from the chains, organic material did not appear in the storage media until the fourteenth day of immersion. X. Latex elastics and synthetic elastomers have certain similarities and differences. The latex elastics showed a greater amount of loss in strength than plastic elastomers when stretched over a 21 day period.5 There is a great variability, as much as 50%, in the tensile strength of the plastic materials taken from the same batch and stretched under the same conditions. 5 The force decay of synthetic elastomers, stretched over a specific length and time, exhibited a great loss in force. This loss could be as great as 73% during the first day. The decay of force continued at a slower rate during the rest of the 21 day period. 5 The Ormco Power Chain was more resilient than the Unitek AlastiK chain. The Unitek AlastiKs had more force and stretched less. 5 Unitek AlastiK C2 double links, when stretched 17 millimeters, had a higher initial force averaging 641 grams (22.5 ounces) than the Ormco Power Chain which averages 342 grams (12.0 ounces). In one day the force was reduced to 171 grams (6.0 ounces) for both materials. 5 15

  • XIII. Infection (Contamination) control a) Gloves Despite the most careful precautions, a certain percentage of gloves will always fail. It also appears that, to date, latex is a more reliable material than vinyl for gloves that are worn to avoid the spread of infection. Furthermore, since it appears that a number of gloves will be punctured in use, it is important that other aspects of cross-infection control, such as hepatitis B vaccination for those placed at risk and effective sterilization and disinfection procedures, must be emphasized. Most punctures occurred in the left thumb and forefinger, despite the fact that all the clinicians were right-handed. A number of the gloves investigated had more than one puncture.37 b) Elastomeric Module Changer Although ceramic brackets have made orthodontic treatment acceptable to many adults, staining of clear elastomeric ligature modules by certain foods can still create an unesthetic appearance. a simple tool that allows the patient to change stained modules at home. (Always tie in rotated teeth with stainless steel ligatures.)38 The changer is made of .028" stainless steel wire with one end bent into a handle and the other bent into a hook. The patient is shown how to engage the hook under the elastomeric module and remove it. Each patient is given a length of closed elastomeric chain and shown how to place an individual link under the bracket wings and cut it from the chain with a scissor.38 c) Presectioning Elastomerics to Avoid Cross-Contamination One of the weakest links in the barrier control chain has been individual and chain elastomeric ligatures. If they are removed from trees, canes, or spools at chairside, the unused ligatures become contaminated. Ten minutes of “cold sterilization” serves only to disinfect, not to sterilize. Even the disinfection requires considerable rinsing and drying and may result in degradation of the material.39 Uses an 18-section tackle box with the top removed, cover the box at night and leave it uncovered during office hours.39 One section is filled with individual elastomeric ligatures. Other sections hold cut-up trees of two, four, six, eight, and 10 ligatures, and another contains presectioned chain sections of two, four, six, eight, 10, and 12. Various separators and rotation wedges are also in the box. Elastomerics are removed as needed with a sterilized tweezer, reducing the risk of contamination.39 Keep clear and gray ligatures in separate sections; the clear chains seem to discolor faster once they are removed from the spool. Try to use all the ligatures in a section before adding new ones.39 27

  • VI. Prestretching effects 1. Chains Attempts to alleviate the large initial force degradation and improve the constancy of force delivery have led several investigators to look at the effects of prestretching the elastomeric chains before placement. Andreasen and Bishara recommend an initial extension of the chain of four times the desired force level to compensate for inherent force loss.12 Young and Sandrik8 conclude that extending chains three to four times the desired force would result in permanent deformation of the chain and subsequent reduction in the desired force level. And they recommended initial extension of the chains by 50% to 75% of the original length to provide an optimal force level. Wong,5 recommended prestretching the elastic chains a third of their original length to prestress the molecular polymeric bonds and improve the strength. Some products may require an extension of 100% to generate force levels of 300 gm, whereas others extended by this amount would provide excessive force levels.3 Kuster et al.,20 compared the chains of two companies stored in air and in vivo. Chains stored in air were extended to 82% and 115% of the original length and, after 4 weeks, had maintained 70% to 75% of their initial force level. Chains placed in vivo at approximately 100% extension retained 43% to 52% of their initial force level after 4 weeks. At 100% extension, the force levels of the two chains were 315 gm and 279 gm, respectively. Kovatch et al.21 reported that rapidly extended chains showed greater initial force levels than those slowly stretched. At 1 week, however, the chains stretched at the slow rate exhibited less force decay. Therefore they recommended slowly stretching the modules to position 2. Elastics The empirical rule of “3” indicating that the reported force level is achieved on extending the elastic three times its diameter, does not apply to all cases and shows remarkable variation, ranging from 2.7 to five.18 VII. Analyses of elastic force Intramaxillary elastics Intramaxillary elastics are used between two points in the same dental arch.6 (e.g., class I elastics from canine to first permanent molar) Intermaxillary elastics Intermaxillary elastics are used between the maxillary and the mandibular dental arches.6 9

  • force values at 100% extension were constant for each individual material. They also noted that all short filament chains, with the exception of Unitek AlastiKs, produced higher initial force level at 100% extension, the initial forces being in the range of 403 to 625 gm. This led Rock et al.16 to recommend extending chains to 50% to 75% of their original length to provide the desired force of approximately 300 gm. In general, the most force decay occurs at the first hour, and the greater the initial force, the greater the force decay of all chains.17 2. Elastics Stretching a rubber elastic of 7 mm. diameter to 20 mm. exerts a pressure as high as 168 grams. A 30 mm. stretching gives 243 grams and 40 mm. 350 grams.6 Most of the relaxation was shown to occur within the first 3–5 hours after extension, regardless of size, manufacturer, or force level of the elastics.18 In a study to evaluate latex elastic band fatigability, of three band sizes most commonly used for intermaxillary mechanics, both in-vivo and in-vitro over a period of 21 days. initial gram pulls were 320, 220 and 160 grams for elastic band sizes 3/16", 4/16" and 5/l6" successively, when stretched 30 mm., and 350, 260 and 190 grams when stretching the same bands 35 mm. successively.19 Both samples showed initial force drop at the end of the first day. The average drop was more in the vivo sample group, it was about 31% to 53% compared to the 26% to 47% force loss of the in vitro sample group. The second force drop was reported by the end of the 7th day (37% to 61%) for the in vivo sample. This percentage loss was more or less constant till the end of the 14th day, and then followed by third force drop by the end of the l5th day (58% to 63%), and fourth force drop at the end of the 21 days of the study ranging between 65% to 75 %. These findings were different from those obtained from the in vitro sample group in that; the second force drop at the end of the7th day was equal to 36% to 53%, and the third force drop (40% to 58%) was reported at the end of the 14th day, and then maintained its level till the end of the 21 days period.19 Force analysis, indicated that, residual remaining force after 14 days of intermaxillary mechanics, and is not of sufficient magnitude to produce effective tooth movement. 19 So for practical and clinical purposes, and to maintain the initiation of orthodontic tooth movement in the desired direction by intermaxillary mechanics, elastic bands must be changed at a maximum of two weeks interval.19 The distal driving force component is about 97.5% and 75% of the elastic force; with the mouth closed and widely opened respectively this factor must be considered during force analysis. 19 8

Control group consisted of 9 unused specimens of each ligation Type. Each elastomeric ligature in dingen observed under the scanning electron microscope (SEM) to determine variations in size. The archwire-bracket-ligature complex zur Frage nachdem analyzed. Transparent O-ring ligatures showed significant volumetric and structural changes. The external rounded shape zur Frage rather maintained, while the internal shape tended to appear square. Both external and internal Diameter significantly increased (p<0. 005 and p<0. 0001 respectively) while the thickness decreased ( p<0, 005) when analyzed with t-test. Polyurethane ring-shape ligatures retained the Anfangsbuchstabe Windung Plan. Both außerhalb and internal Durchmesser increased (p<0. 0001), while the thickness remained almost unchanged. The internal border was Mora squared, and showed jagged edges with continuous and irregular extroversions. Grey, polyurethane Slide low-friction ligatures showed a reduced dimensional change.
