Case studies 201
The fi nal prosthesis was completed in silicone, as has become the most
commonly used clinical technique (10). The mould surface was fi rst painted
with silicone colour matched to the patient’s skin (Fig. 6.68) and then
packed out to form the body of the prosthesis. The mould was then clamped
closed and the silicone cured. Once the main body of the prosthesis
was completed, fi nishing details such as eyelashes and extrinsic colour
were added to improve the realism. The result can be seen in Figs. 6.69
(a and b).

The ability to work on the prosthesis in conjunction with the patient’s
anatomy on the computer means that the patient does not have to remain
present during much of the design stage. This signifi cantly reduces clinic
appointment time and inconvenience to the patient. The ability to view the
