Background technique
As the application of Computer Aided Surgery restores original function and mentions accurately to construct ideal new Mandibular Morphology
Possibility has been supplied, virtual operation plan can help doctor to work out reasonable operation plan, and it carries out operation rehearsal and predicts surgical effect,
And threedimensional model, pre-bending titanium plate and the various osteotomy of production and moulding guide plate are printed according to analog result, to ensure doctor in reality
The process of virtual operation plan is repeated in operation, to help doctor to complete accurate cranio-maxillofacial excision and reconstruction operations, outside
Section's guide plate and pre-bending titanium plate are the direct embodiment of virtual operation plan in the course of surgery, therefore, the essence of guide plate and pre-bending titanium plate
It is really that can virtual operation plan the key factor that accurately implement in art in place.
Traditional 3D printing surgical template mainly be bonded by configuration of surface to mandibular and anatomic landmark it is in place,
The determination of jawbone osteotomy site to be completed, mobile deflection is easy, error is larger, in addition, the titanium plate of preoperative pre-bending, and by remaining
It stays the surface anatomy mark of jawbone to guide titanium plate in place, equally exists large error, the snap-system of people is quite accurate, jawbone
The slight error of reconstruction is likely to cause postoperative patient meshing functionss disorder, causes quality of life to decline, patent
CN107951538A discloses a kind of surgery that can be guided simultaneously and carry out segmental mandibular excision with the positioning of preform reconstruction titanium plate
Guide plate helps accurately to restore occluding relation and maintains the stabilization of condyle position, improves operation precision, but its guide plate is in place
Mode does not still change, and performs the operation uncertain big, easily causes mandible osteotomy site inaccurate.
Summary of the invention
To solve the problems mentioned above in the background art.It is accurate in place using tooth conjunction guidance that the present invention provides a kind of
Jawbone osteotomy guide plate and preparation method thereof has the characteristics of accurate in place, accuracy height and mandibular Exact Reconstruction.
To achieve the above object, the invention provides the following technical scheme: a kind of close the accurate jawbone in place of guidance using tooth
Osteotomy guide plate, including guide plate, it is characterised in that: the top of the guide plate is provided with area in place, and the lower part of the guide plate is provided with
Hole location area, the side of the guide plate are provided with osteotomy slot.
Preferably, the hole location area is provided with several circular holes, and the quantity of circular hole is no less than three.
It is a kind of to close the accurate jawbone osteotomy guide plate production method in place of guidance using tooth, include the following steps:
S1, the data for acquiring patient's jawbone simultaneously import in operation designing simulation softward, rebuild jawbone threedimensional model；
S2, jawbone Osteotomy is determined according to extent of disease, and fibula simulation is migrated into jaw defect area, formed and rebuild
Expection jawbone model afterwards completes expected jawbone model according to each fibula segment length of expected mandibular shapes reverse and osteotomy angle
Design；
After S3, the expected jawbone model entity of printing, according to model pre-bending titanium plate, then according to titanium plate hole location, in model reality
The corresponding target position punching of body, then carries out rescan to the model after punching；
S4, patient's lower jaw tooth modulus is given, is perfused plaster cast, then laser scanning mandibular teeth data, and by lower jaw tooth
Data are merged with the model data after punching；
S5, guide plate design include two parts, and top is area in place, carry out maintenance design according to dental morphology；Lower part is hole
Position area, is designed according to titanium plate hole location corresponding on model；Finally printing is formed to be carried out in place according to dental morphology, and is had
The Mandible Osteotomy of titanium plate fixed hole digitizes surgical template；Side is osteotomy slot；
S6, surgical template production: digitlization surgical template is exported into 3D printer and completes production and post-processing.
Compared with prior art, the beneficial effects of the present invention are:
The accurate jawbone osteotomy guide plate and preparation method thereof in place of guidance is closed using tooth the present invention provides a kind of, is realized
In the surgical procedure of Mandible Osteotomy, guide plate is accurately quickly arrived into desired location in place, improves Mandible Osteotomy and titanium plate just
The accuracy of position, helps to realize mandibular Exact Reconstruction.
