ABSTRACT:
Dental apparatus for recording the interdental relationship of anterior teeth has an open frame and a handle. A bite tray (9) is secured within the frame so that impression material applied to the bite tray can be readily manipulated between a patient's anterior teeth. The frame may be formed from upper and lower pivotally interconnected arcuate parts (2, 5) and the bite tray (9) has an arcuate segmental body of flexible perforated supporting material with a stiffened strip (10) around its curved periphery. This strip (10) is clamped between confronting faces (15, 16) of the parts (2, 5) and is located in position by engagement of pins (8) on the lower part (2) with holes (11) in the strip (10).
