Abstract:
A method of manufacturing a fixed denture ( 18,58 ) is disclosed comprising, identifying the surface of a tooth preparation ( 110 ), relating the identified surface to a near net shape version of the denture ( 120 ), and altering the near net shape version ( 130 ) to produce a denture having an inner profile which substantially replicates the surface of the tooth preparation ( 140 ). The inner profile may include an offset ( 36 ). The surface of the tooth may be identified by digitising the surface. The near net shape can be altered by machining. The near net shape version may be a pre-formed sintered ceramic shell ( 20 ) which may comprise one of a plurality of standard tooth shapes ( 40 ) from which the most appropriate shape is chosen or an individually produced tooth shape ( 42 ). The fixed denture may be for example a coping ( 18 ), bridge ( 58 ), implant support abutment.
