Positioner for secondary part of crown supporting false tooth

摘要

The secondary part (31) supporting the false tooth (2) grips over the primary part (3). At least two guide-cups (14,14a) which are cylindrically hollowed-out along at least part of their length are fixed to the primary part in parallel alignment. The cups (16) of the guide-cups face away from each other. Cylindrical friction pins (15) fit into the cups and match the number, position and shapes of the guide cups, inside the secondary part.
