Abstract

The invention relates to an orthodontic device. The orthodontic device is utilized for orthodontic treatment of the dentistry. The orthodontic device can be implanted into the upper jaw (the oral cavity top) having good bone quality and thin soft tissue thickness, wherein an implanted part is fixed by a mini-implant and two side hanging buckles are hanged on cheek sides so that a whole dentition is drawn back for orthodontic treatment. The orthodontic device allows movement of teeth located at molar positions and does not need implantation of a mini-implant. Through the orthodontic device, the cheek sides are provided with action points of a distally-directed traction on the whole dentition comprising a molar column so that an active force (a corrective force) can be produced easily. The orthodontic device can naturally induce a dental arch (a dentition arch which is an arched body for tooth growth) to expand, and can dislodge the dentition back and correct them thereby greatly reducing tooth extraction possibility.

Description

Dentition correcting device

Technical field

The present invention relates to a kind of Dentition correcting device, this Dentition correcting device comprises: it is good and can be used as the maxillary position of absolute stationary source that implantation portion, this implantation portion are implanted in sclerotin; Both sides buckle portion, and this both sides portion of buckling buckles in both sides molar buccal (molar cheek sidepiece) respectively; And hook spare, this hook spare is arranged on and buckles the portion end, and can hook elastomer, and this device rearward draws whole dentures and corrects, thereby carries out orthodontics very effectively.

Background technology

Generally; When correcting denture; Carry out Dentition correcting with following method: carriage is adhered to and is fixed in Buccodental (pure side) or lingual surface (tongue side); After connecting steel tinsel (wire) on the above-mentioned carriage, on inner day bow part in oral cavity or alveolar bone, implant and be fixed for fixedly the mini implant of denture (mini-implant: below be called " stationary source ") after, buckle rectification and move tooth with elastomer.

Promptly; After rectification assists tooth (not needing corrigent normal tooth) and object of correction dental surface (front or back) to go up the bonding carriage of difference; With one or more steel tinsels that carriage is interconnection; The oral cavity bent part in inner day or alveolar bone is partly implanted stationary source and fixing; To be fixed in the steel tinsel by elastomer one side end that the camber line of disc spring, gum elastic or different shape etc. is formed, the elastomer end side then buckles on stationary source, makes tinsel keep certain rate of tension; So that the object of correction tooth moves and obtains correcting to the normal position, this stationary source is implanted in by Dentition correcting direction and corrective force and on the alveolar bone (Hubei Province bone) of definite position.

In the past, stationary source as screw the same, simply form by head and threaded portion; After alveolar bone is implanted in the threaded portion, elastomer is buckled on the cervical region that connects head and threaded portion, correct denture with this; When the said fixing source applied turning moment, stationary source can not be resisted its revolving force (turning moment), and the elastomer tendency that has the cervical region at stationary source to move up and down; Inflammation or complication occur thereby bring out gingiva (gingival tissues), prolong the improvement time.

On the other hand; When the tooth (front tooth) that is fixed in Hubei Province bone is outstanding forward, stationary source is fixed to the side alveolar bone, and draws with elastomer; Can be easy to straightening of teeth; But the tooth (front tooth) that is fixed in Hubei Province bone is when letting droop, and utilizes active force (pulling force) or lateral active force upwards that tooth is upwards drawn, with orthodontics to the normal position.

At this moment, need whole tooth portion be moved to the top sometimes, traction rearward simultaneously, but utilize the existing stationary source of molar process to regulate merely.

For whole tooth portion is rearward moved; Existing method is to implant a stationary source in molar process one side to draw; Move backward when moving up for whole tooth portion; Need regulating the height of molar process stationary source implantation position and the hook that is connected in arch whole tooth wiry portion, perhaps regulate through crooked arch tinsel, is unusual difficulty but correctly regulate direction that tooth moves.

In addition, for preventing to correct the rotation of auxilliary material, performing an operation the auxilliary material head of rectification was implanted in the gingival tissues in the past, thereby needed to cut gums; The patient is not only agonizing, and is inflamed easily on every side, moreover; After the use, remove when correcting auxilliary material or replacement the incision gums of need having an operation; Make and correct auxilliary material head to exposing outside, operation and recovery required time are long, bring very big misery to the patient.

In addition, when correcting denture, stationary source is arranged in side or the oral cavity; So that denture moves backward, if but stationary source that the sclerotin at position is set is bad, then can not be as absolute stationary source; And cheek side alveolar bone is bad or interdental space hour, can not the cheek side be used for fixing the source.

In addition, owing to molar position tooth moves, so need replant into stationary source; Owing to be not can whole structure or the method that moves denture, so the application point that the rear pull strength can occur being provided with difficulty relatively is difficult to have an effect; Dental arch is difficult to expansion, a lot of problems such as exodontia probability raising.

That is, when stationary source (mini-implant) is set on the molar process cheek side, because the tooth at molar position moves; The situation that needs to implant again frequently takes place; Not only the improvement time prolongs, and need replant into stationary source, can not simultaneously the whole denture that comprises molar process rearward be moved.

Summary of the invention

The purpose of this invention is to provide a kind of Dentition correcting device; This Dentition correcting device is implantable in the good maxillary position of sclerotin; And buckling in the buccal, both sides, is the very outstanding absolute stationary source that is used for Dentition correcting, and on the structure; Be provided for the application point of the rear pull strength of whole denture in the cheek side, easily firmly.

Another object of the present invention provides the implantation portion and the hook spare of various structure.

The present invention implants implantation portion and is fixed in the good maxillary of sclerotin (being the top, oral cavity) and goes up as absolute stationary source, and the both sides portion of buckling buckles respectively in the buccal, both sides, and whole denture is rearward drawn and straightening of teeth; The tooth that has prevented molar process moves, and need not to replant into stationary source, owing to be provided for comprising the application point of rear pull strength of the whole denture of molar row in the cheek side; Corrective force acts on easily; And induce the expansion of dental arch naturally, thus utilize the rear pull strength to move denture, significantly reduced the probability of exodontia; Because it has multiple implant infrastructure and hook spare structure, application is good.
