Fixture for teeth model support of articulator

摘要

The fixing device is for the support (16), of the teeth-model, which comprises a dovetailed container (15) into which a dovetailed piece (21) joined to an adjusting base plate (18) of the articulator (19) fits exactly. The dovetailed container and piece have conical side surfaces, whose conicity is less than 5 degrees for self-locking. The edges of the side surfaces are rounded. The basic matrix is made of metal or other solid material with a dovetailed container. A casting matrix is made from non-rigid plastics for a gypsum mould (14).
