The invention belongs to the field of maxillofacial plastic
medical instruments, and in particular relates to a CT (computerized
tomography) and CBCT (cone beam computerized
tomography) fusion data based digital
occlusion guide plate and a
reconstruction method thereof. The guide plate has a horseshoe-shaped body, and the guide plate body is provided with a guide plate upper jaw surface, a guide plate lower jaw surface, a guide plate lip outer side and a guide plate lip inner side, wherein the guide plate upper jaw surface and the guide plate lower jaw surface are provided with a groove respectively, and the shape of each groove is fit with the shape of a corresponding
tooth crown. Aiming at the difficulty of reconstructing an occluding relation and the problems that the surgical precision of a conventional model needs to be improved and the like, a CBCT and
spiral CT fusion data based virtual
occlusion reconstruction method, by simulating operative reduction, virtually reconstructing the occluding relation, designing an occluding plate, recording the occluding relation and performing 3D printing to generate a guide plate real object, is used for operatively reconstructing the occluding relation, reducing the operation difficulty, shortening the
operation time, ensuring the operation effect, and improving the reconstruction precision.
