Abstract:
Provided is an articulator which makes relative rotation between a maxilla support part and a mandible support part possible, and is attachable to a support shaft. An articulator 1 equipped with a maxilla support part 10 provided with an upper recess 15 which recesses toward the front, and a mandible support part 20 provided with a lower recess 35 which recesses toward the front and is provided below a lateral recess, wherein a support shaft 70 can be attached between a support shaft-securing member 80 and the upper and lower recesses. A vertically extending upper groove which passes through at the lower end thereof but not at the upper end thereof is formed in the left and right inner surfaces of the upper recess. A vertically extending lower groove which passes through at the upper and lower ends thereof is formed in the left and right inner surfaces of the lower recess along the same straight line as is the upper groove when the mandible support part is rotated to a prescribed angle relative to the maxilla support part. A support shaft-securing member is equipped with a main body section 81, and a wide section 84 and a narrow section 85 provided to the left and right of the main body section. The support shaft-securing member is inserted toward the upper groove from the lower groove side with the wide section on top, the wide section engages the upper groove and does not engage the lower groove when the upper end of the wide section contacts the upper end of the upper groove, and as a result, the mandible support part is capable of rotating toward the front while attached to the support shaft.
