| 摘要 |
A dental articulator includes a pair of attachment members, each adapted to engage a dental casting and a hinge unit including two pivotably interconnected retaining members, each adapted to engage one of the attachment members by means of a joint which may be selectively and reversibly immobilized. The two retaining members are interconnected by a hinge which provides a pair of spaced apart pivot axes for pivoting each of said members and which further provides for the ready and reversible separation thereof.
