Claims

[Claims for Utility Model Registration] 1. A shaft boss 2 installed horizontally at the rear end of the support plate 11 of the maxillary plate 1, and a support shaft 31 mounted on both ends of the shaft boss 2 so as to freely adjust the sagittal condylar path angle. Condyle roadbed retainer 3,3 including
, a condyle roadbed 4 which is attached to each of these supports 3, 3 so as to be able to freely adjust the lateral condylar road angle, and is provided with condylar road grooves 41, 41.
, 4, a pair of condyle frames 6, 6 erected at the rear end of the support plate 51 of the mandibular plate 5, each condyle frame 6
, 6, and the upper and lower jaw plates 1, 5 are connected to the condylar balls 7, 7 and the condylar groove 4.
This occlusal model for dental training is capable of opening/closing, lateral, and back-and-forth movements through the occlusion model 1 and 41. 2. The occlusal model according to claim 1, wherein the groove bottoms 43, 43 of the condylar grooves 41, 41 have bulges 42, 42' that are substantially S-shaped in longitudinal section and allow for lateral displacement of the condylar bulb. . 3. A lock lever 8 provided below the shaft boss 2 and having an opening groove 81 on the tip side, and a support plate 51 for the mandibular plate 5.
The locking rod 9, which is placed lower and into which the open groove 81 of the lock lever 8 can fit, contacts the dorsal part of the condylar path frames 6, 6 during the open bite of the mandibular plate 5, and the condylar bulb 7, A guide regulating device 10 is provided below the support plate 51 to allow the condylar groove 7 to slide forward in the condyle grooves 41, 41.
.
The occlusal model described.
