Mandibular position information recording device based on guide plate

Abstract

The invention discloses a lower jawbone position information recording method based on a guide plate. The method involves a face recording device, face fitting structures and a plurality of point recording device, wherein the face recording device is formed by connecting the bone joint section face fitting structures covering a chin part, a body part and an ascending limb of a lower jawbone, the face fitting structures walk in the projection direction of lower jaw vascular nerve tracts and are used for recording the face position information of all bone joint sections, each point recording device is inserted in the lower jawbone at the corresponding fitting position in the bone joint section corresponding to the face fitting structure where the point recording device is located so as to record the position information of each bone joint section point, the point recording devices are combined with the corresponding bone joint sections, and compensatory close combination positions are formed by the corresponding bone joint sections and the bone joint sections of face recording devices where the point recording devices are located. By means of the determinacy of the face positions andthe determinacy of the point positions, the relative space positions of bone blocks in all sections of the lower jawbone are recorded on the guide plate. The method is simple and accurate and can beconveniently and specifically applied in practice.

Description

technical field [0001] The invention relates to a mandible position recording method, in particular to a guide plate-based mandible position information recording method. Background technique [0002] The chin, body, mandibular angle, and ascending ramus of the mandible are respectively attached to the suprahyoid muscle group, masseter muscle, pterygoid muscle, pterygoid muscle, pterygomandibular ligament and other muscles and ligaments, segmental resection of the mandible After that, the position of the bone block can move and rotate greatly under the pull of the muscle. Therefore, it is necessary to accurately record the position information of the mandible before the osteotomy operation, so as to facilitate accurate repair and reconstruction. Various methods for achieving pre-osteotomy mandible position information recording are known in the art. [0003] In the prior art, the technology of bolting between the upper and lower jaws is to fix the upper and lower dentition...

AI Technical Summary

Problems solved by technology

There are also problems such as a large exposure position, a fixed bracket affecting the surgical field of vision, a large displacement of the bracket steel needle, and a certain amount of rotational displacement in the position of the restored bone block after removal.
