Dentition about just abnormal alignment flattening, prepare the maxillary tooth model after the alignment, the tooth root position of the two side No. 5 of upper jaw of tooth X piece aassessment No. 6 teeth, confirm to plant the nail and implant the position, the craftsman room processing production the utility model discloses supporting device of the supplementary just abnormal removal tooth of wicresoft's jawbone operation to implant position department at the nail, reserve little round hole on the casting plate and regard as positioning hole, the horizontal palate rod of upper jaw of improvement of intraoral bonding, implant the nail, the upper jaw is packed into thicker stainless steel square wire as the arch wire, then implement the operation of getting rid of the cortex of improvement, the postoperative begins to add the anterior tooth in the afterburning immediately, according to intraoral actual conditions, through the traction hook of casting plate front edge, adjust traction. The method comprises the following specific steps:
1. auxiliary orthodontic tooth moving matching device for minimally invasive jaw implantation
A cross palate bar 10 is bonded in the mouth, and a cast band 20 is sleeved on the normal teeth (No. 5, 6 and 7 teeth) at the back side of the extracted teeth. As shown in fig. 2, the supporting device for assisting orthodontic movement of teeth in minimally invasive jaw surgery of the present embodiment extends a casting plate 30 in the buccal-lateral tooth root direction between the two lateral maxillary teeth No. 5 and No. 6, and during the manufacturing process, care should be taken to avoid the bracket, buccal tube and orthodontic wire, and the height is close to the mucosa turning point (i.e. the joint between the upper part of the gum and the buccal surface, if the teeth divide the oral cavity into an inner part and an outer part, the inner part is the tongue part, the outer part is the part between the teeth and the cheek or the lips, and the mucosa turning point can be understood as the uppermost part outside the oral cavity). The casting plate 30 is positioned at one third of the root tips of No. 5 and No. 6 tooth roots and is reserved with a positioning through hole 31, the diameter of the positioning through hole is about 2mm, and the casting plate is used for implanting the implant anchorage nail. The implant anchorage nail is driven into the positioning through hole 31, driven between teeth, penetrated through gingiva and driven into bone tissues, and is used for connecting and fixing the casting plate 30 with No. 5 and No. 6 gingiva or even alveolar bone.
3 small-sized traction hooks, namely first traction hooks 32, extend from the front edge of the casting plate 30 at different heights and are used for internally retracting upper front teeth, and the traction direction can be adjusted according to the height. The first pulling hook 32 with different heights can be pulled with the second pulling hook 42 on the arch wire, but the direction of the force is different, when the first pulling hook 32 at the lowest part and the second pulling hook 42 on the arch wire are pulled with each other, the pulling force is nearly horizontal, a vertical component force is rarely generated, and the highest component force is just opposite, which is selected according to clinical needs.
The two ends of the cross palate bar 10 are respectively connected with 3 casting belt rings 20, the 3 casting belt rings 20 are tightly connected, and the connecting parts between the belt rings are adapted to the normal tooth gaps. In use, the cast band 20 is adhesively fitted over the teeth.
The arch wire 40 is movably connected with a fixing piece at the corresponding position of the buccal side tooth surface of No. 1, 2, 3 and 5 teeth, the fixing piece is an orthodontic bracket 411, and the orthodontic bracket 411 is bonded with the buccal side of a normal tooth when in use so as to penetrate, support and fix the arch wire 40. The buccal sides 6, 7 connecting the cast band ring 20 fixedly connect the buccal tubes 412 with the archwire 40 passing through the buccal tubes 412. The arch wire 40 is also provided with a second draw hook 42.
The casting plate 30 and the second pulling hook 42 are respectively positioned at both sides of the tooth extraction part (tooth No. 4). The first draw hook 32 on the cast plate 30 is connected to the second draw hook 42 on the archwire 40 by a pulling device.

2. Cortical bone partial removal
After the extraction heals for 4-5 months, the cortex lycii radicis at the buccal side of the first premolar extraction area is removed in a strip shape, the width is the width of the extraction area, the depth is the whole layer of cortex lycii radicis, the height reaches the apical part and is connected with the incision of the horizontal under-apical osteotomy made at the apical part of the upper premolar area. And (3) removing the cortical bone strip on the palatal side in the tooth extraction area of the first premolar, connecting the shortest path with the opposite side, wherein the width is the width of the tooth extraction area, and the depth is the cortical bone whole layer. If necessary, the fracture of the bone block in the anterior maxillary tooth area can be made. The removal of the cortical portion of the bone can loosen the anterior teeth, reduce the resistance of the anterior teeth to the movement toward the tooth extraction space, make the anterior teeth move backward more easily, and thereby adduct the anterior teeth.
To sum up, the utility model designs a mode and a device of reinforcing anchorage that part upper jaw cortex was got rid of in operation to supplementary planting implant nail adduction anterior teeth. Because cortex lycii is the main resistance of adduction of restriction anterior teeth district tooth and alveolar bone, the utility model discloses furthest's removal anterior teeth adduction route goes up cortex lycii, has reduced the resistance of adduction in-process, and furthest's increase the anchorage in back tooth district simultaneously, furthest's reduction back tooth antedisplacement finally reaches the furthest and addals the anterior tooth, improves the purpose of face type.
While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description. Accordingly, the scope of the invention should be limited only by the attached claims.
