Abstract
A kind of guide plate for the minimally invasive osteotomy of tooth maintenance, including biteplate, bindiny mechanism and osteotomy guiding mechanism.Bindiny mechanism one end is connect with biteplate, and the other end is connect with osteotomy guiding mechanism.Bindiny mechanism includes arc structure, adapts to the osteotomy demand of different situations, such as: the radian of arc structure is big (such as: >=100 °), the small (k≤40m of curvature‑1) or neighbouring without healthy denture, then it is suitble to mouth to turn up valve bone-culting operation, for another example: the radian of arc structure small (such as: 90 °) is simultaneously with neighbouring tooth, then suitable for bone-culting operation in mouth.Guide plate for the minimally invasive osteotomy of tooth maintenance of the invention, low-profile are suitable for minimally invasive bone-culting operation, it is only necessary to which exposure osteotomy site and later period titanium plate fixing glue hole site avoid excessively dissecting exposure mandibular bone face, and largely retain existing flesh attachment.
Description
Technical field
The present invention relates to a kind of auxiliary tools more particularly to a kind of guide plate for decorative sursery for bone processing, just
In tooth maintenance treatment in implement minimally invasive bone-culting operation.
Background technique
Digitlization Computer Aided Design is applied to the treatment serious jaw defect of Maxillary region and deformity, such as: congenital hair
Maxillofacial deformities caused by educating answer maxillofacial defeet caused by wound or tumour.Pass through CAD and 3D printing
Technology makes model or guide plate, in conjunction with technologies such as microvascular anastomosis, free bone transplantation and orthognathic surgeries, implements essence to patient
Quasi- medical treatment restores function and the appearance of patient.
Guide plate is made of guide portion and positioning region, and positioning region is integrally fastened to tissue for guide plate, and guide portion is set to
On positioning region, its specific location and angle are determined according to CAD, so as to organizing and implementing precisely operation.
Guide plate is applied in mandible reconstruction in digitlization surgery, generally uses the supported osteotomy guide plate of bone.That is guide plate
The working face of guide plate is needed to be bonded with lower jaw bone surface in place.For such guide plate, need to dissect special construction using jawbone
(such as: angle of mandible, ascending branch rear, chin ridge/chin knuckle and the U-shaped radian for crossing mandibular middle line), to assist guide plate in place, otherwise
Guide plate will be slided in lower jaw bone surface, and mistake occurs for the position for causing surgeon to place osteotomy guide plate.Osteotomy is thus generated to miss
Difference causes digital surgical to fail.Since the prior art is insufficient to the operation margin of safety, seriously then there is postoperative recurrence, because
This osteotomy guide plate accurately seems extremely important according to digitlization Computer Aided Design in place.
Further, since the supported osteotomy guide plate of bone needs to wrap up multiple jawbones dissection special constructions, this also means that, outside
Section doctor needs detachment to adhere to muscle, exposes mandibular sufficiently so that guide plate is sufficiently in place, can smoothly guide bone-culting operation.
The detachment of flesh attachment, will destroy muscle function, even if subsequent be sutured in jawbone, the fibrosis healing of muscle for muscle, it is also difficult to
Realize that muscle adheres to and functions again, this just violates the principle of jawbone reconstruction.
Summary of the invention
