A mid facial prosthesis also known as an orbital prosthesis is a substitute for the mid face and orbital region that has been lost due to birth defects, accidents or surgery.
If you're an individual who has lost either a part or whole of the orbital or mid face then a prosthetic replacement would be ideal for you. This option prevents the need for further surgery and provides you with much better aesthetic results.
Following healing in the region of the facial defect a specialised impression will be taken. A personalised wax mock-up with an eye if required will be fabricated for the defect for your approval. This wax model will be duplicated in a skin like material called silicone. The colour and texture of this silicone will be adjusted to suit your skin tone so that no difference is seen between the defect and the prosthesis.
Adhesive retained: The prosthesis in such cases will be retained by means of a special water - soluble adhesive. You will be shown how to apply and use this adhesive with your prosthesis.
Spectacle mounted: With larger defects or in cases where you already wear spectacles then we can attach your prosthesis to your existing frames. This form of mechanical retention is ideal if you have undergone radiation therapy which prevents the use of adhesives.
IF IMPLANTS ARE PLACED WITHIN THE DEFECT AREA – if you are suitable for implant placement and opt for the same then the retention and aesthetic outcomes of your prosthesis greatly improves. We will be happy to assist you in determining whether this option is indicated for you. If you have any queries please feel free to contact us regarding the same.
Implant Bar Retained Prosthesis: An implant bar will be fabricated out of Cobalt Chromium Metal and will be fixed onto the implants. The silicone prosthesis will attach itself onto this bar by the means of elastic clips. This is the most basic means of retention for a facial prosthesis.
Implant Bar Prosthesis retained by Magnets: The implant bar will be fabricated and fixed onto the implants. A set of magnets will be attached to the bar as well as the silicone prosthesis. This makes placement of the prosthesis much easier and increases the lifetime of the prosthesis significantly.
Magnetic Bar Retained Prosthesis: The implant bar itself is made out of a special magnetic alloy (EFM alloy). This makes the entire assembly and prosthesis much more compact allowing a more life like and natural appearance. This is the best form of rehabilitation available.
The prosthesis is made out of a specialised silicone material that is sensitive to UV radiation and moisture.
Monsieur Lorrain, a French locksmith, offered one of the most important contributions to the field of prosthetics when he used leather, paper and glue in place of heavy iron in making a prosthesis.
