Abstract
A dental prosthesis is disclosed includes a prosthetic tooth element comprising ceramic and a veneer located on a surface of the prosthetic tooth element, the veneer comprising cured dental composite. The prosthetic tooth element can be fixed to a mount in a patient's mouth using the same dental composite used for the veneer. A method of forming a prosthetic tooth element is disclosed including filling a mould that is formed at least partially from flexible polymeric material with a dental mixture comprising ceramic, and applying pressure to the filled mould to form a prosthetic tooth element comprising ceramic with a roughened surface.

A method of forming a prosthetic tooth element comprising:
- filling a prosthetic tooth element-shaped recess of a compression mould with a dental mixture comprising ceramic, the compression mould comprising a first mould part and a second mould part that are brought together to form the prosthetic tooth element-shaped recess, at least one of the first and second mould parts comprising a flexible polymeric body and a rigid plate located at an outer surface of the flexible polymeric body;
- and
- applying pressure to the plate to compress the dental mixture and form a prosthetic tooth element comprising ceramic, wherein the pressure is applied at greater than 0.5 tonnes per square centimetre or greater than 1.0 tonnes per square centimetre or about 2.0 tonnes per square centimetre to cause vibration of flexible polymeric material of the mould such that the prosthetic tooth element is formed with a roughened surface.
A compression mould for forming a prosthetic tooth element comprising ceramic, the mould comprising:
- a first mould part and a second mould part adapted to be brought together to form a prosthetic tooth element-shaped recess, at least one of the first and second mould parts comprising a flexible polymeric body and a rigid plate located at an outer surface of the flexible polymeric body;
- wherein the compression mould is configured to be filled with dental mixture comprising ceramic and for a pressure to be applied to the plate to compress the dental mixture and form a prosthetic tooth element comprising ceramic, the plate being configured to withstand application of the pressure at greater than 0.5 tonnes per square centimetre or greater than 1.0 tonnes per square centimetre or about 2.0 tonnes per square centimetre to cause vibration of the flexible polymeric body such that the prosthetic tooth element is formed with a roughened surface.
