These type of facial prostheses are the most difficult to construct but we do our best to produce a prosthesis that is as realistic in appearance as possible.
In the construction of an orbital prosthesis certain steps need to take place.
Overview:
And impression is taken of the facial defect and working models are then cast. With the patient in attendance an ocular prosthesis is custom made according to the shape, colour and characteristics of the natural eye.
The finished artificial eye is correctly positioned and then the orbital prosthesis and surrounding tissues are carved into wax.
The waxed prosthesis is tried on the patient, corrections are made till all functional and aesthetical criteria are met.
A mould is made and, with the patient present, silicone base material is mixed and skin colour matched, then packed into the mould.
The orbital prosthesis is finished off and placed onto the patient.
Prostheses are retained by medical adhesive fixation (stick on) or by placing osseointegrated implants to which the prosthesis can be attached by using a clip system.
The placement of titanium implant fixtures and abutment placement can be done as one surgical operation or placed in two different operations. The time allowed for osseointegration of the implants into the bone will be determined by the surgeon but a period of approximately 3 months is ussually accepted.
We do assist with the ordering of the implants to be placed and by constructing a surgical stent we can also assist in planning the location of the implant sites. If it pleases the patient and the surgeon we can be present in the operating theatre and at all relevant comnsultations.
