BITE DISPLAY DEVICE FOR VERIFYING INFLUENCE OF TEMPOROMANDIBULAR JOINT ON BITE

摘要

PURPOSE: To verify the normal, abnormal or undesirable bite in the bit of the upper jaw and the lower jaw by the bite model of the temporomandibular joint, which model is used for diagnosis, treatment and education in the field of dentist and dental education and is easily produced and to easily explain such bite for understanding. ;CONSTITUTION: An upper member 3 modeling the upper jaw 32, the maxillary teeth 33, the cavity X and the ring vertebra 34, a lower member 4 modeling the lower jaw 41, the mandibular teeth 42 and the condyle Y, a hyoid like member 5 modeling the hyoid and a cervical vertebra-like member 6 modeling the vertical vertebra and thereunder are arranged together with the side head part 31 of the cranium on the surface of a base plate. The upper member 3, the lower member 4 and the hyoid like member 5 are constituted as moving plates and the certical vertebra-like member 6 is constituted as a stationary plate. The section corresponding to the condyle head part Y of the lower member 4 is provided with an oscillation iterating means 7 modeling a joint disk so that the condyle head part turns on the outer side of the condyle Y and oscillates iteratively while oscillating on the inner side of the cavity X.;COPYRIGHT: (C)1995,JPO
