Bone-anchored implant retention for facial prostheses

We use bone anchored implants to enhance security and simplify use of a prosthesis. When craniofacial implants are selected, we work directly with the surgical team. We provide the surgeon with a custom-made guide to identify the ideal location for placing the implants. We also discuss with you in detail all of the steps in the treatment that are required in order to complete a bone-anchored facial prosthesis.

Craniofacial bone anchored implants provide several advantages over adhesive retention
including the following:

• The useful life expectancy of the prosthesis is extended
• Aesthetic results are enhanced with very thin edges that blend with the skin
• The inconvenience of cleaning of adhesive products from the skin and prosthesis is avoided
• The prosthesis is attached in proper position with ease
• Patients report greater confidence in secure retention

Placement of craniofacial bone anchored implants requires one or two minor surgical procedures. Threaded titanium fixtures are surgically implanted into the bone by your surgeon. Then a connection component, called the abutment, is installed onto the fixture. The abutment extends through a small surgical opening in the skin. Your surgeon may also thin the skin around the abutment to prevent soft tissue complications. The implants are allowed to heal for roughly three months, permitting a bond or osseointegration to form between the titanium fixture and the bone.

After the healing phase, we take a new impression (moulage) and attach specialized components that provide secure attachment of the prosthesis. The most commonly used retention components are magnets and/or a gold bar framework with corresponding clips in the prosthesis.
