A kind of method for designing strengthening orthopedic force appliance mouth inner part fixing device

Technical field

The invention belongs to mouth cavity orthodontic technical field, be specifically related to a kind of method for designing strengthening orthopedic force appliance mouth inner part fixing device。

Background technology

Malocclusion refers to that child is in growth and development process, by inborn inherited genetic factors or posteriori environmental factors, such as disease, oral habit, for the tooth that tooth exception etc. causes, jawbone, the deformity in cranium face, showing as tooth arrangement uneven, the jaw relation between upperdental arch is abnormal, jawbone size and form malposition etc.。IS-One III class anterior crossbite is a kind of developmental anomaly, refers to that lower labial teeth is positioned at incisor lip side, is commonly called as " Bao Tian "。Anterior crossbite occurs with the growth promoter of child, develops, and the sickness rate in China is about 5-12%, is a class deformity clinically more typically, has a strong impact on that infant face is attractive in appearance, be engaged even function of pronunciation。Anterior crossbite deformity is divided into Odontogenic cysts, functional and bone three class, and the bone that wherein causes due to upper jaw deficiency of development is counter to be closed relatively conventional and clinical treatment is relatively difficult。

It is treatment anterior crossbite of paramount importance period for the tooth phase, by growing remodeling treatment, utilizes the growth potential of patient, promote the upper jaw of deficiency of development to grow forward, to treat deformitas maxillaris, guide tooth to close face and grow trend normally。Substantial amounts of bibliographical information shows, use molar distalization device to promote upper jaw bone to grow forward, rescue upper jaw deficiency of development relatively other technologies such as chin pocket, functional appliance, to cover up treatment etc. more successful, therefore, it is current correction clinic early treatment's bone anterior crossbite deformity most common method。Anterior crossbite appliance is divided into two parts, a part to be that head cap or mask are used as extra-oral anchorage。Another part is part in mouth, bears and conducts pull strength to the upper jaw。It is that rear teeth plane closes cushion removable appliance for the mouth inner part that the tooth phase is conventional, close pad in order to release anti-conjunction, requirement maintenance is good, can bear the outer orthopedic force of the mouth more than 400g and be unlikely dislocation, but the appliance design of routine exists some problems in maintenance:

First, because the denture morphological variation for the tooth phase is relatively big, as deciduous teeth come off, the non-eruption of permanent teeth or eruption are not enough, and tooth is not enough without undercut or undercut, causes that appliance maintenance is poor, it is impossible to lead before implementing upper jaw bone smoothly。

Second, have been reported that bonding with tooth for removable appliance to increase maintenance, but the method is worn owing to patient oneself can not pluck and cleans appliance, therefore appliance cleaning and oral hygiene can not be kept, and doctor needs to take off appliance when adjusting afterburning, infant is more painful, and appliance is also frequently subjected to damage。

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, give patient more effective more comfortable treatment, it is desirable to provide a kind of method for designing strengthening orthopedic force appliance mouth inner part fixing device, have that method is simple, retention effect good, what be especially suitable for the tradition frequent poor effect of anchoring methods replaces denture infant, bent without bending complex spring, simple to operate；Patient wears with convenient, comfortable, it is easy to keep health；And price economy。

To achieve these goals, the technical solution used in the present invention is: a kind of method for designing strengthening orthopedic force appliance mouth inner part fixing device, comprises the steps:

First, maxillary first molar is tried on band, specific practice is: trying band on maxillary first molar on, band is closely connected with tooth, does not interfere with occlusion, does not stimulate gingiva；

Second, turn over donsole inner teeth gear plaster model, specific practice is: first take a mouthful inner teeth gear die by dentistry alginate material, band is in place in upper jaw left and right sides first molar, band is not bonding with first molar, being taken off from first molar by the band tried is placed in the former produced again, and then records plaster model on die with Gypsum Fibrosum；

3rd, creative activity appliance on this plaster model, the specific practice of this step is:

With correction macromolecular material creative activity appliance base, base covers the system of turning over upper jaw left and right sides first molar band on plaster model, the appliance suppressed is taken off from plaster model, again with the bonding hook for Anterior crossbite of self curing plastic at the lip side appropriate site of appliance, enhancing orthopedic force appliance mouth inner part fixing device can be obtained；

In this step, if simultaneously need to upper jaw rapid palatal expansion, expansion screw being adhered on appliance。

Described band adopts and is made up of stainless steel substrates or alloy piece。

The invention has the beneficial effects as follows:

On tooth, finished product band is tried on owing to present invention employs；Turning over the method for designing of tooth plaster model creative activity appliance processed, method for designing is simple, and it is strong that designed appliance has retention；Simple to operate, it is not necessary to bend various maintenance bent；Maintenance adnexa is easily obtained；Patient's comfortable wearing, it is simple to cleaning；It is suitable for for denture；The feature of price economy。

Detailed description of the invention

Below in conjunction with specific embodiment, the present invention is described in further detail。

Embodiment: patient Wang, man, nine years old, anterior crossbite, upper jaw deficiency of development, orthodontic treatment plan was lead the anti-conjunction of releasing before the upper jaw is fixed, and improves and is engaged and face type。

A kind of method for designing strengthening orthopedic force appliance mouth inner part fixing device, comprises the steps:

First, maxillary first molar is tried on band, specific practice is: try band on maxillary first molar on, band used is the preformation rustless steel band that new Asia, Hangzhou company produces, its buccal aspect is welded with little drag hook and buccal tube, determines that No. 27 bands and tooth are closely connected through trying on, and within its week, footpath is about 4cm, and do not interfere with occlusion, do not stimulate gingiva；

In this step, if simultaneously need to upper jaw rapid palatal expansion, expansion screw is adhered on appliance, being worn in entrance by appliance, because the buccal tube on band, the adnexa such as drag hook is closely chimeric with removable appliance, and band is fitted closely with tooth, just constitute highly stable retention system together, make removable appliance lead before being enough to undertake the upper jaw, expand the treatment of the orthopedic forces such as bow。
