Description

Elastic press-in type arch wire protection silica gel sleeve

Technical Field

The invention belongs to the field of orthodontic treatment, and particularly relates to an arch wire protection silica gel sleeve used in tooth fixing and correcting, which is used for preventing an orthodontic arch wire from being scratched and damaging oral mucosa and improving the attractiveness and comfort of fixing and correcting.

Background

The traditional bracket fixing and correcting method is that a metal or ceramic bracket is usually bonded on the buccal labial surface of a tooth, a nickel-titanium wire or a stainless steel wire is ligated into a groove, the tooth is expected to move by applying force through deformation of an arch wire, and finally correction is completed. In the stage of aligning and leveling dentition, nickel-titanium round wires and square wires with good elasticity and poor rigidity are often needed to gradually arrange teeth; the later stage needs tooth torque adjustment, when closing or opening up the clearance, just needs the stainless steel square wire that elasticity is poor, rigidity is good to reach the purpose.

Although the fixed correction technology is mature and widely used clinically, the fixed correction technology has a plurality of disadvantages. According to clinical practice and feedback of patients, the main problem is that the comfort level is poor, patients often need a period of time to adapt, even can not adapt, and finally correction can not be continued, mainly because brackets bonded on the labial and buccal sides and the arch wire entering the grooves are continuously scraped and rubbed to damage oral mucosa, and traumatic ulcer occurs; in addition, if the ligation interval of the elastic nickel-titanium round wire used in the initial correction stage is longer, the tail end of the arch wire is easy to be separated from the buccal tube due to the activity interference of soft tissues, the number of times of the patient's repeated diagnosis is increased, and the satisfaction degree of operation diagnosis is reduced; finally, some patients use ceramic brackets with high aesthetic value, however, the arch wire used in later correction is still in metal color, which undoubtedly reduces the aesthetic value and also becomes a main reason that many patients finally give up selecting ceramic brackets. Aiming at the problems of the orthodontic arch wire, some clinicians can use a half infusion tube to be sleeved on the arch wire between the brackets, the problems are solved to a certain extent, but the arch wire needs to be penetrated before the arch wire is ligated, the operation is complex, the operation treatment time beside the chair is prolonged, the infusion tube is transparent, the aesthetic improvement is meaningless, the professional image of orthodontic treatment is damaged when the infusion tube is used, and even a patient can generate conflict psychology.

Therefore, the problem that the arch wire between orthodontic brackets scratches oral mucosa is solved, simple and convenient operation is provided, the fixed attractive degree of correction is improved, and the method is very important.

According to our search, at present, no patent related to the orthodontic arch wire protection device exists at home and abroad.

The diameter of the inner circle surface of the elastic press-in type arch wire protection silica gel sleeve is 2.0mm, and all arch wires including full-size steel wires (0.0215 inches x 0.028 inches) can be accommodated. Simultaneously, elasticity forced arch wire protection silica gel cover is soft, even use the nickel titanium round wire of 0.012 inch diameter, can not change the arch wire shape yet, influences the tooth row.

The three colors A1, A2 and A3 of the restoration colorimetric method are adopted, so that doctors can conveniently select the closest color according to different tooth colors of patients, the metal color of the arch wire is covered, and the attractiveness is improved; if the arch wire is provided with the push spring or the seal spring, the arch wire and the push spring can be wrapped together.

This elasticity forced arch wire protection silica gel cover can effectively improve the patient and wear the comfort level of correcting the ware, no matter be square wire or round wire, and the homoenergetic avoids its and mucous membrane's scraping, prevents effectively that dental ulcer.

For thinner and softer arch wires, the elastic press-in type arch wire protective silica gel sleeve can effectively avoid the interference of soft tissues and food, so that the thin wires are not easy to separate from buccal tubes.

A doctor can intercept an arch wire protection silica gel sleeve with proper length after the arch wire is completely ligated into the slot and various accessories are in place according to the length of the arch wire to be protected between the brackets, and the arch wire protection silica gel sleeve is quickly installed on the arch wire, so that the safety protection method is convenient and quick.

The invention also discloses a use method of the elastic press-in type arch wire protection silica gel sleeve, which comprises the following steps: after the arch wire is completely tied into the slot and the accessory is installed, selecting an elastic press-in type arch wire protective silica gel sleeve which is closest to the tooth color of a patient; roughly measuring the length of the arch wire between the two brackets so as to cut a section of silica gel sleeve; aligning the bevel notch with the arch wire, gradually lightly pressing from one side to wrap the arch wire to the other side, and lightly screwing the silica gel sleeve to ensure that the arch wire is completely wrapped and cannot be separated; sequentially operating to wrap the arch wires of the rest segments, and paying attention to wrap the arch wires with push springs, sealing springs and other positions; and finally, checking that the inclined plane notches of the silica gel sleeve face the tooth surface.

The invention has the beneficial effects that: the tooth color fixing device is small and exquisite in structure, durable and safe in material, low in production cost, simple in operation, capable of meeting the tooth color of most patients due to color typing, and capable of effectively improving the comfort level and the attractiveness of fixing correction.
