Description

Double-arm arch tooth grinding righting spring

Technical Field

The utility model relates to an orthodontic field, in particular to a double-arm arch molar righting spring matched with a main arch wire and a bracket of an orthodontic fixed appliance.

Background

Along with the increasing importance of people on the beautiful appearance of teeth, the research on the tooth fixing and correcting technology is gradually deepened, the tooth orthodontic technology (also called as tooth correction) is gradually developed, orthodontics mainly researches the etiology and mechanism of malocclusion deformity, diagnoses, analysis, prevention and treatment, and different correcting methods can be adopted for different malocclusion deformities.

In orthodontic clinical applications, it is necessary to treat patients with arch expanders in cases where the arch is narrow or the upper and lower arches are not coordinated and are manifested as retrodentate retroocclusions. The traditional bow-expanding device is provided with a spiral expander, a four-eye ring bow-expanding spring, a thick wire expansion auxiliary bow and the like. The structures of the spiral expander and the four-eye ring expansion bow spring are complex, and the installation, the disassembly and the force adjustment are inconvenient. The thick wire expansion auxiliary bow is convenient to operate and does not need the cooperation of a technician, so the thick wire expansion auxiliary bow is frequently applied. The narrow most emergence of patient's dental arch is in two cusp tooth district and molar district, and traditional thick silk extension is assisted the arch and is only accomplished with a thicker arch wire and form, and under main arch wire was arranged in to its anterior segment, fix on the support groove of fixed correction ware through the ligature silk, and the width of its rear segment both sides was greater than the width of patient's dental arch under initial condition, and compression thick arch wire and with its back ligature fix on the support groove of fixed correction ware during the treatment, utilizes its back stretch elasticity to expand patient's dental arch. But on one hand, the diameter of the arch wire is thick, and patients feel uncomfortable, and on the other hand, the rebound resilience is small, is difficult to control accurately, and has large deviation in correction. Meanwhile, under the influence of reaction force, arch wires on two sides of the rear section of the arch wire are expanded in the buccal direction and simultaneously can certainly cause palatal movement of the arch wire of the front section, namely the expansion of the posterior teeth of a patient can cause the contraction of the anterior teeth, the contraction is mostly negative movement which is not needed for correction, and the expansion force of the posterior teeth of the patient is limited by the arch wire of the front section, so that the correction effect of a thick arch wire is difficult to effectively exert.

The utility model discloses a grant utility model patent of publication No. CN201001783Y discloses an arch is assisted in extension of both arms elasticity in mouth, and this arch is assisted in extension of both arms elasticity includes one and is assisted the arch maintenance arch that the main arch wire of ware is rescued with the just abnormal fixed in oral cavity and support the groove cooperation and use to be equipped with a pair of elasticity extension arch that bends back to first molar department from side incisor department on arc maintenance arch both sides, the tip on the arch is extended to elasticity is equipped with the couple, and the arch is fixed to the fixed position of arc and elasticity extension arch can be fixed on main arch wire or support the groove through ligature silk traction. Although the double-arm elastic expansion bow has better resilience and better correction effect compared with the traditional single-arm expansion bow device; but the resilience force of the expansion arm is not best when the orthodontic bracket is used, the expansion arm is directly connected with a main arch wire and a bracket of the orthodontic fixed appliance, the stability is poor, the expansion arm is tied with the main arch wire through a tying wire, and the tying part of the expansion arm is positioned on the labial surface of teeth, so that the injury and the ulcer of oral soft tissues are easily caused. In addition, because the expansion arm and the fixed arm are directly fixed on the main arch wire of the orthodontic fixed appliance, the stress requirement of the main arch wire is higher, so the main arch wire is fixed by the molar belt ring, the lingual button is adhered to the lingual side of the molar belt ring, and the oral soft tissue injury and ulcer are easily caused.
