Abstract
A method of forming a prosthetic tooth element (104) is disclosed, the method comprising depositing a first hardenable fluid material (101) at a bottom of a cavity (111) of a female mould (110) to a first level (113), the first material having a first translucency when hardened; depositing in the cavity (111), over the first material (101), a second hardenable fluid material (102) to a second level (114), the second material having a second translucency when hardened, the second translucency being less translucent than the first translucency; and inserting a male mould (120) into the cavity (111), the insertion of the male mould displacing at least a portion of the second material (102) within the cavity (111).
