Embodiment Construction

[0049] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] It should be noted that the following embodiments only focus on the parts related to location information, and other operations are only briefly described.

[0051] first reference figure 1 , segment the mandible. The mandible is divided into mandibular chin 1, mandibular body 2, mandibular angle area 3 and mandibular ramus 4.

[0052] as attached figure 2 As shown in Fig. 1, secondly, a complementary fitting surface recording guide is designed in each segment, and the surface recording guide fitting the mandible is divided into the surface structure 5 covering the ascending ramus, the surface structure 6 covering the mandibular angle, and the surface structure covering the mandibular body. The facial structure 7 of the mandible and the facial structure 8 of the chin of the mandible. A plurality o...

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...
