Abstract

The invention provides a drawing chain and ring, which is composed of two forms including drawing rings and catenating type drawing chains. The impendent drawing rings mainly comprise five types and the difference is that sizes and ring diameters of the five types of the drawing rings are different. Each catenating type drawing chain is composed of a fixed ring and the drawing ring. Each fixed ring is relatively provided with the two drawing rings and each drawing ring is relatively provided with the two fixed rings, so as to form the catenating type drawing chain by mutually and annularly connecting the drawing rings and the fixed rings. The quantity of the drawing rings is 1 more than that of the fixed rings and two free ends are the drawing rings. The sizes of the fixed rings are different and the sizes of the drawing rings are also different. A numerical value of the drawing chain at a tongue side is reduced compared with the ratio of a bracket at the same tongue side of a lip side bracket, namely the numerical value is the numerical value of the catenating type drawing chain at the tongue side. The independent drawing ring has good flexibility, the fixed ring of the catenating type drawing chain has good stability and the drawing ring has good elasticity and flexibility.

Description

Haulage chain, the circle of mouth cavity orthodontic balance appliance

Affiliated field:

In the balance fixed orthodontic operating process of mouth cavity orthodontic field for interactional reset components between malposed tooth and the malposed tooth.

Background technology:

At present adopt curved usually to the adjustment between malposed tooth and the malposed tooth clinically or the elastic traction chain is accomplished; Under simple and efficiently guiding theory; Accomplish the form of dental arch adjustment relatively between malposed tooth and the malposed tooth efficiently, be meant an important step of correcting in the flow process.In the process of operation, commonly used have a single elastic traction circle, and continuous elastic traction chain is arranged, and shape has nothing in common with each other.But because the making of traction circle or chain is irregular or nonconformingly in clinical operating process, often the overcorrection phenomenon is appearred in rectification effect; Can know the operator under the prerequisite of each traction circle or chain; Use traction apparatus then can efficiently accomplish the adjustment of denture relatively between malposed tooth and the malposed tooth, improve a lot correcting flow process.As corrigent individuality; Difference between individuality and the individuality is clearly; Because the distance that denture and denture differ between the rectification individuality has nothing in common with each other; Requiring under the prerequisite of same power value; The reaching the power value of wanting and can accomplish through the traction circle that varies in size of nature, in denture and correct that to accomplish traction under the common prerequisite of the difference that exists between the individuality then be the key link that improves whole rectification flow process relatively between malposed tooth and the malposed tooth, now employed clinically rectification traction circle and chain then are obviously can not reach this requirement.Wherein there is manufacturer's factor that the factor of material is also arranged, also has some atypical factors to cause jointly.Whole relatively rectification system, strict says, having accurate design part is the prerequisite of accomplishing a high standard rectification effect with comprehensive rectification plan.Correcting individuality, correcting between parts and the rectification plan three, with the fusion of its science, according to the situation of correcting individuality; Plan is corrected in the adjustment of science, and according to correcting individual requirement, requirement is corrected in the design of science; Could accomplish the high standard operation of case; The traction chain ring then is the first-selection of under the prerequisite of this requirement, accomplishing at short notice, so rational and effective uses and have more clinical meaning, has progradation to improving clinical manipulation.

Summary of the invention:

This traction circle, chain are to be formed by high-elastic rubber manufacturing, have better elastic and tractive property, in the oral cavity, have good anti acid alkali performance ability simultaneously.This traction circle, chain are to be made up of traction circle and haulage chain; This traction circle, chain are rounded form under naturalness, and the circle body of traction circle, chain is similarly rounded form, and the traction circle mainly contains five types separately; Following of naturalness is form for circular, and it is circular that the circle body form is similarly.Five types different places be that the size of five circles and the diameter of circle round body there are differences; The size and the circle body diameter of five types of traction circles are respectively: A circle body diameter is 0.8 millimeter; Circular diameter is 3.2 millimeters in the traction circle, and traction circle overall diameter is 4 millimeters; B circle body diameter is 0.8 millimeter, and circular diameter is 4 millimeters in the traction circle, and traction circle overall diameter is 4.8 millimeters; C circle body diameter is 1 millimeter, and circular diameter is 6 millimeters in the traction circle, and traction circle overall diameter is 7 millimeters; D circle body diameter is 1 millimeter, and circular diameter is 8 millimeters in the traction circle, and traction circle overall diameter is 9 millimeters; E circle body diameter is 1.2 millimeters, and circular diameter is 10 millimeters in the traction circle, and traction circle overall diameter is 11.2 millimeters.The catenated form haulage chain is made up of ring for fixing and traction circle, and ring for fixing is the rubber ring that is fixed on the bracket, and the traction circle then is the rubber ring of the draw between ring for fixing.Interconnect between ring for fixing and the traction circle, promptly exist relatively among each ring for fixing near far away in two traction circles, and among each traction circle also mutually to there being two ring for fixings, ring for fixing and traction are enclosed each other articulating and are formed the catenated form haulage chain.Because the varying in size of bracket, the size of ring for fixing is also inequality, simultaneously since between tooth body and the tooth body nearly middle distance far away different, the size that traction is enclosed goes out inequality.In the whole chain of catenated form haulage chain; Because need matching with the near middle hook of cheek side pipe, two free-ends could accomplish distraction procedure; The traction circle is Duoed 1 than the number of ring for fixing; Two free-ends then all are the traction circles, and the size of catenated form haulage chain is respectively with the circle body diameter: the size of ring for fixing is identical with the circle body diameter left and right sides.Maxillomandibular numerical value is listed respectively: the upper jaw, and the circle body diameter of central incisor is 0.6 millimeter, and the circle interior diameter is 3 millimeters, and the overall diameter of ring for fixing is 3.6 millimeters; The circle body diameter of lateral incisor is 0.6 millimeter, and the circle interior diameter is 2.8 millimeters, and the overall diameter of ring for fixing is 3.4 millimeters; The circle body diameter of canine tooth is 0.6 millimeter, and the circle interior diameter is 3 millimeters, and the overall diameter of ring for fixing is 3.6 millimeters; The circle body diameter of first bicuspid is 0.5 millimeter, the circle interior diameter be 2.8 millimeters, ring for fixing overall diameter be 3.3 millimeters; The circle body diameter of second bicuspid is 0.5 millimeter, encloses to diameter is 2.8 millimeters, and the overall diameter of ring for fixing is 3.3 millimeters; Lower jaw, the circle body diameter of central incisor is 0.5 millimeter, and the circle interior diameter is 2.5 millimeters, and the ring for fixing overall diameter is 3 millimeters; The circle body diameter of lateral incisor is 0.5 millimeter, and the circle interior diameter is 2.5 millimeters, and the ring for fixing overall diameter is 3 millimeters; The circle body diameter of canine tooth is 0.6 millimeter, and the circle interior diameter is 3 millimeters, and the ring for fixing overall diameter is 3.6 millimeters; The circle body diameter of first bicuspid is 0.5 millimeter, and the circle interior diameter is 2.8 millimeters, and the overall diameter of ring for fixing is 3.3 millimeters; The circle body diameter of second bicuspid is 0.5 millimeter, and the circle interior diameter is 2.8 millimeters, and the overall diameter of ring for fixing is 3.3 millimeters.The effect of ring for fixing is that the pull strength that distraction procedure forms is fixed on the bracket; Act on the tooth body through bracket and accomplish rectification; Therefore the tractive extension degree of ring for fixing is starkly lower than the traction circle; The alteration of form characteristics that both stress showed are that ring for fixing stress form stable degree encloses apparently higher than traction, and ring for fixing shape stability under the prerequisite that forms pulling force is better.The traction circle then is just big more at the long more formed value of thrust of distance of the situation stretched of stress, and when stress value was zero under naturalness, the form of traction circle was circular; The long more formed value of thrust of distance of situation stretched just big more, when stress value was zero under naturalness, the form of traction circle be a circle; Because hook links to each other in the cheek side pipe that two free-ends of traction circle need near, therefore the number of traction circle is 11, equates about the numerical value of maxillomandibular traction circle; Be respectively: the upper jaw, the circle body diameter of the traction circle of nearly middle hook to the second bicuspid of cheek side pipe is 0.8 millimeter, the circle interior diameter is 2.5 millimeters; The overall diameter of traction circle is 3.3 millimeters, and the circle body diameter of the traction circle of second bicuspid to first bicuspid is 0.8 millimeter, and the circle interior diameter is 2.2 millimeters; The overall diameter of traction circle is 3 millimeters, and the circle body diameter of the traction circle of first bicuspid to canine tooth is 0.8 millimeter, and the circle interior diameter is 2.5 millimeters; The overall diameter of traction circle is 3.3 millimeters, and the circle body diameter of the traction circle of canine tooth to lateral incisor is 0.8 millimeter, and the circle interior diameter is 2.2 millimeters; The overall diameter of traction circle is 3 millimeters, and the circle body diameter of lateral incisor to central incisor traction circle is 0.8 millimeter, and the circle interior diameter is 2.5 millimeters; The overall diameter of traction circle is 3.3 millimeters; The circle body diameter of traction circle is 0.8 millimeter between central incisor and the central incisor, and the circle interior diameter is 2.5 millimeters, and the overall diameter of traction circle is 3.3 millimeters.Lower jaw, the circle body diameter of the traction circle of hook to second bicuspid was 0.8 millimeter during the cheek side pipe was near, the circle interior diameter is 2.5 millimeters; The overall diameter of traction circle is 3.3 millimeters, and the circle body diameter of the traction circle of second bicuspid to first bicuspid is 0.8 millimeter, and the circle interior diameter is 2.2 millimeters; The overall diameter of traction circle is 3 millimeters, and the circle body diameter of the traction circle of first bicuspid to canine tooth is 0.8 millimeter, and the circle interior diameter is 2.2 millimeters; The overall diameter of traction circle is 3 millimeters, and the circle body diameter of the traction circle of canine tooth to lateral incisor is 0.6 millimeter, and the circle interior diameter is 2 millimeters; The overall diameter of traction circle is 2.6 millimeters, and the circle body diameter of the traction circle of lateral incisor to central incisor is 0.6 millimeter, and the circle interior diameter is 2 millimeters; The overall diameter of traction circle is 2.6 millimeters; The circle body diameter of the traction circle between central incisor and the central incisor is 0.6 millimeter, and the circle interior diameter is 2 millimeters, and the overall diameter of traction circle is 2.6 millimeters.Because the area (front) of linguoplate groove is littler than conventional lip side bracket, the numerical value of the catenated form haulage chain that uses in the tongue side then dwindles the numerical value that is the used a chain of haulage chain of tongue side according to lip side bracket with the ratio of linguoplate groove on year-on-year basis.This balance is only rectified, and used haulage chain, the circle of device all is to be made with medical grade rubber; Independent part pearl traction circle has retractility preferably; The used material of the ring for fixing of catenated form haulage chain and traction circle is different, and ring for fixing has good stable property, and the stretching resistance effect is obvious; The traction circle then has better elastic and retractility, and traction circle, chain all are to be made with medical grade rubber.
