Model operating instrument for upper jaw osteotomy

摘要

The invention describes a model operating instrument for upper jaw osteotomy, with a basic frame on which it is possible to adjust the position of the two temporo-maxillary articular cups; from the side, there protrudes into the osteotomy plane a universally mounted disc which is rotatable in its own plane and which is displaceable in three directions at right-angles to one another, on which disc it is possible to fix an upper jaw model keyed with a lower jaw model.
