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).

A method of forming a prosthetic tooth element comprising:
- depositing a first hardenable fluid material at a bottom of a cavity of a female mould to a first level, the first hardenable fluid material having a first translucency when hardened;
- depositing in the cavity, over the first hardenable fluid material, a second hardenable fluid material to a second level, the second hardenable fluid material having a second translucency when hardened, the second translucency being less translucent than the first translucency, wherein the deposition of the second hardenable fluid material in the cavity occurs before insertion of any male mould into the cavity that causes any displacement of the first hardenable fluid material;
- and
- inserting a male mould into the cavity when the first hardenable fluid material and the second hardenable fluid material are fluid, the insertion of the male mould displacing at least a portion of the second hardenable fluid material within the cavity.
