The invention discloses a combined tooth appliance, which comprises a tooth socket and at least one bracket, wherein the bracket is bonded and fixed on the tooth surface of a tooth with serious dislocation, notches which are matched with each other are correspondingly reserved on the tooth position of the tooth socket, when the tooth socket is pressed on the tooth, the bracket on the tooth with serious dislocation extends out through the corresponding notch on the tooth socket, a segment arch wire is arranged on the tooth socket, two ends of the segment arch wire are respectively connected on the left and right adjacent tooth positions of the notch of the tooth socket, when the tooth with serious dislocation needs to be corrected, only the bracket is arranged on the corresponding tooth and the notch is reserved at the corresponding tooth position of the tooth socket, the tooth socket is pressed on the tooth and the segment arch wire passes through the groove of the bracket, the arch wire provides larger correcting force to correct the tooth with serious dislocation, so that a patient can quickly align the teeth with serious dislocation only by wearing a small number of transparent tooth sockets, effectively solves the problems of more correction steps and long correction period of the case with serious malposition of teeth.

Description

Combined tooth appliance

Technical Field

The invention relates to the technical field of orthodontic appliances for oral teeth, in particular to a high-efficiency combined tooth appliance.

Background

Orthodontic treatment refers to the arrangement of irregular teeth of a patient by a dental appliance. Orthodontic brackets are common dental appliances that are designed to straighten teeth by securing each bracket to the surface of the tooth with an adhesive and applying various types of corrective forces to the tooth with an archwire passing through the slots of each bracket. With the application of computer aided design and manufacturing technology, a bracket-free transparent tooth socket appears on the market, has the advantages of beauty, picking, sanitation and the like, is widely applied, is pressed by high polymer plastics, and is worn by a patient at different stages by a series of transparent tooth sockets and gradually corrects malpositioned teeth by utilizing the elasticity of the high polymer plastics. But because the elasticity that polymer plastic formed in the process of correcting is weaker than the correction power that the arch wire formed in traditional just abnormal bracket, so when correcting the more serious case of tooth dislocation, need decompose into more and correct the step, the preparation is more transparent facing, corrects the inefficiency, corrects the cycle length.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a combined tooth appliance with high correction efficiency and low correction cost.

The technical scheme adopted for solving the technical problems is as follows: a combined tooth appliance comprises a tooth socket and at least one supporting groove, wherein the supporting groove is fixedly bonded on the tooth surface with serious dislocation, at least one notch matched with the supporting groove is reserved on the tooth position of the tooth socket correspondingly, when the tooth socket is pressed on the tooth, the supporting groove on the tooth with serious dislocation extends out through the corresponding notch on the tooth socket, a segment arch wire used for being clamped into the groove of the supporting groove is arranged on the tooth socket, and two ends of the segment arch wire are respectively connected on the left adjacent tooth position and the right adjacent tooth position of the notch of the tooth socket.

Further, the space of the tooth position with the gap on the tooth socket is larger than the volume of the tooth with serious malposition.

Furthermore, connecting pipes are respectively formed on the tooth positions of the tooth socket adjacent to the left and the right of the notch, and two ends of the segment arch wire respectively penetrate through the corresponding connecting pipes to be connected and fixed.

Further, the connecting pipe and the tooth socket are integrally formed, or the connecting pipe and the tooth socket are detachably connected.

Furthermore, the bracket is provided with a personalized bottom plate attached to the tooth surface of the tooth, and a net bottom is formed on one surface of the personalized bottom plate attached to the tooth surface of the tooth.

Furthermore, the groove of the bracket is a vertical groove or a horizontal groove.

Further, the segment arch wire is a nickel titanium round wire.

Further, the tooth socket is a transparent tooth socket.

Has the advantages that: this ware is rescued to combination formula tooth has combined the characteristic of having no support groove transparent facing and just abnormal support groove, when needs are rescued serious dislocation tooth, only need set up the support groove on corresponding tooth and reserve the breach in the corresponding position department of facing, the facing cover is pressed on the tooth and is made the segment arch wire pass the groove in support groove, utilize the arch wire to provide great correction power and correct the tooth of serious dislocation, make the patient only need wear less quantity's transparent facing, alright arrange the tooth of serious dislocation fast, it is many to have solved the serious case of tooth dislocation effectively and correct the step, correct the problem of cycle length.

Detailed Description

Referring to fig. 1 to 8, the combined dental appliance of the present invention comprises a mouthpiece 10 and at least one bracket 20, wherein the bracket 20 is adhesively fixed on the tooth surface of a tooth with serious dislocation, at least one notch 11 matched with the bracket 20 is reserved on the tooth position of the mouthpiece 10 correspondingly, when the mouthpiece 10 is pressed on the tooth, the bracket 20 on the tooth with serious dislocation extends out through the corresponding notch 11 on the mouthpiece 10, a segment arch wire 30 for being clamped into a groove 21 of the bracket 20 is arranged on the mouthpiece 10, and two ends of the segment arch wire 30 are respectively connected on the left and right adjacent tooth positions of the notch 11 of the mouthpiece 10.

Wherein, the tooth socket 10 is located on the adjacent tooth position about the breach 11 and is formed with the connecting pipe 12 respectively, and the both ends of the segment arch wire 30 pass corresponding connecting pipe 12 respectively and connect fixedly to make the segment arch wire connect and fix on tooth socket 10, connecting pipe 12 and tooth socket 10 can be integrative design, also can be split type design.

According to the actual situation of the teeth of a patient, grooves in different directions can be formed on the bracket to achieve the expected tooth movement, and when the groove 21 of the bracket 20 is designed to be a horizontal groove, the tooth can move in the directions of labial cheek direction, lifting, pressing and axial inclination by matching with an arch wire; when the slot 21 of the bracket 20 is designed as a vertical slot, the teeth can be twisted in the buccal, lingual, depressed and first sequence plane directions by cooperation with the archwire.

Preferably, the tooth position space with the gap 11 on the mouthpiece 10 is larger than the volume of the tooth with serious malposition, and usually, each tooth position space on the mouthpiece 10 is matched with the size of the tooth, so that the tooth position space with the gap 11 on the mouthpiece 10 is designed to be larger, and a certain moving space can be provided for the tooth with serious malposition.
