Description

A device for erecting impacted molars

technical field

The utility model relates to the technical field of oral tooth correction, in particular to an upright device for impacted molars.

Background technique

The teeth are abnormally positioned in the jaw due to soft tissue or bone resistance, and cannot erupt into the normal occlusal position, which are called impacted teeth or impacted teeth. Impacted permanent teeth are a common phenomenon in orthodontics, the most common being mandibular molars. The current methods for upright molars include surgical replantation and orthodontic-assisted traction. Although surgical replantation is simple and quick, it will cause complications such as loss of pulp vitality, root resorption, and root-bone adhesion. When the traditional fixed appliance method is used to erect molars, in order to increase anchorage, most of the dentition needs to be removed. In this way, it increases the discomfort of patients, affects the appearance, and often causes molar elongation, which is difficult to achieve a satisfactory treatment effect, and increases the treatment time and chairside operation time.

For example, the invention patent application with the application number of 201210194090.3 discloses an orthodontic device for anteriorly inclined impacted molars. The device includes a fixation member for anteriorly inclined impacted molars, a premolar fixation member for anteriorly inclined impacted molars, a spring coil, a spring The two ends of the ring are respectively connected with the forward-inclined impacted molar fixing member and the pre-molar fixing member of the forward-inclined impacted molar. The rod, the premolar fixing member of the anteriorly inclined impacted molar comprises a straight rod, an upwardly bent rod located at the front end of the straight rod, and an outwardly bent rod located at the upper end of the upwardly bent rod. During the treatment, it is necessary to fix the entire dentition with a stainless steel frame (except the anteverted impacted molar), and then use the triangular gap formed by the anteverted impacted molar and the previous molar to set the device in the triangular gap, and the anteverted The laterally bent rod of the premolar fixation member of the impacted molar extends from the side of the premolar of the premolar to the premolar of the premolar along the naturally formed groove of the molar. The middle part of the surface is fixed to the middle part of the upper surface of the pre-molar of the pre-inclined impacted molar by means of bonding, the elastic force is stored by pre-compressing the spring coil, and the pre-inclined impacted molar fixing member is attached to the pre-inclined impacted molar along the pre-inclined impacted molar. The naturally formed groove on the surface is positioned on the upper surface of the anteverted impacted molar and fixed by bonding, and the spring coil is released. The purpose of tilting impacted molars.

This orthodontic device has the above-mentioned problem - it requires the participation of most of the dentition or even the entire dentition, which will increase the discomfort of the patient and affect the aesthetics. Therefore, there is an urgent need to design a new technical solution to comprehensively solve the problems existing in the prior art.

Utility model content

The purpose of the present utility model is to provide an upright device for impacted molars, which can effectively solve the problem that the existing orthodontic device requires the participation of most of the dentition, easily causes patient discomfort, often causes molar elongation, and is difficult to achieve a satisfactory therapeutic effect. question.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A device for erecting impacted molars, comprising anchoring nails, buccal tubes and a bent cantilever beam, the bent cantilever beam includes an adjustment ring, a fixing piece arranged at one end of the adjustment circle and a correction piece arranged at the other end of the adjustment circle , the fixing member is a straight rod, and the correcting member includes a straight rod and a curved end arranged at the end of the straight rod; the anchoring nail is fixed in the alveolar bone between the proximal and middle teeth of the impacted molar , the buccal tube is fixed on the buccal position of the impacted molar, the fixing piece is placed in the buccal tube and is fixedly connected with the buccal tube, and the curved end of the orthodontic piece is located under the anchor nail when the force is not applied, and the force is applied. fixed on the anchoring nail.

A further solution is that the buccal tube is a buccal tube with a specification of 0.022×0.028 inches.

A further solution is that the curved end of the belt is in a semi-circular arc shape, and the anchor nail is a micro-implantation nail with a diameter of 1.6 mm and a length of 8 mm.

A further solution is that the bent cantilever beam is made of 0.019 inch×0.025 inch stainless steel wire.

The impacted molar erection device provided in the above technical solution has the advantages of simple structure, convenient use, small volume of anchorage nails, small trauma, simple operation, and flexible implantation, and the previous part of the dentition or the whole dentition of the anchorage nail bag body is used as the anchorage. It can effectively reduce the discomfort of the patient without affecting the aesthetics; in addition, the distal end of the curved cantilever beam is designed with a retrograde bend, which is inserted into the buccal tube, and the required angle can be adjusted according to the inclination of the impacted teeth. The utility model effectively solves the problems that the traditional fixed orthodontic technique of upright and inclined molars requires most of the dentition to be included in the treatment, which increases the discomfort of the patient, affects the aesthetic appearance, and causes the elongation of the molars and the poor effect; The operation time is also correspondingly long, the present invention only needs to implant anchor nails, and the corresponding operation time will be greatly reduced.
