ABSTRACT:
Dental apparatus for recording the interdental relationship of posterior teeth has spaced apart longitudinal supports (1, 2) between which longitudinal side members (7, 8) of a bite tray (5) are releasably engaged. The bite tray has supporting material (6) for supporting impression material, between the side members (7, 8). The side members (7, 8) may extend over inner faces of the longitudinal supports (1, 2) to protect against contact between the impression material and the supports (1, 2). The longitudinal members (7, 8) may be channel members which slide along or snap-fit over rail-shaped supports (1, 2). In an alternative embodiment the side members may engage slots (13, 14or18, 19) in the supports (11, 12or16, 17).
