Craniofacial osseointegration of a large midfacial bone-anchored combination maxillofacial prosthesis: a clinical...

The combination of retentive clips and magnets has been used with favorable results for smaller facial prostheses. This patient's large midfacial defect created the need for an attachment design that would retain an intraoral obturator prosthesis and a large silicone facial prosthesis. The advantages of this design include having an obturator that is separately attached by clips to the framework. This allows the patient more ease in insertion and removal of the prosthesis. It also allows for better oral hygiene. The magnets aid the patient in the proper alignment of the facial prosthesis. The O-ring attachment was not a complicated technique in this patient's treatment. The patient can, without the use of a mirror, snap the rubber matrix O-ring attachment over the patrix attachment on the framework. This resulted in a retentive facial prosthesis, which helped the patient feel more secure. The silicone margins were well adapted to the patient's skin, which allows the use of thin translucent margins and the elimination of the inherent problems associated with the use of adhesives.
