It is impossible to make use of the living body for making prosthetic appliance. It is therefore ideal if the upper and lower jaw relation and the mandibular movements can be exactly reproduced mechanically. In the course of pursuing this objective, many articulators and face bows have been developed to date since Gariot introduced the first articulator of hinge action in 1805. In 1949 at the college, ex-professor Tsubone devised his articulator aimed chiefly for making full dentures. This is a semi-adjustable articulator and features the forms of the condylar guide lane and of incisal guide path. Occlusal form which excels functionally of artificial teeth can be formed on the articulator. With 30 years of its clinical applications, a number of improvements have been added by the department with Toyoda as leader and the modification has been presented as the Tsubone's T Type Face Bow and MS Type Articulator. The main improvements are as follows : 1. Adjusting mechanism for inter-condylar distance has been added. 2. Screws for adjusting CO-CR have been added. 3. Immediate side shift can be adjusted. 4. With one face of the rotating cube at the incisal guide as a plane fossa, guide plates for dentulous patients can be made of self-curing resin. 5. Because of the orbital plane indicator mounted and the elevating screw mounted under the condylar posts, the hinge axis and the condylar shaft of the articulator are in exact agreement. This paper considers theoretically and in details the improvements made and also describes the importance of locknuts for condylar balls.
