Abstract

Background: Maxillofacial defects caused by cancer treatment are a huge problem affecting the quality of life of patients. Some of these deformities are minimized using facial epitheses, which need some additional retention devices like glasses or skin adhesives. The use of extraoral fixtures as bone anchorage was introduced many years ago and since then many patients were rehabilitated with better results. Purpose: Because of poor bone conditions, for example, irradiated bone, the success rate of extraoral implants is less than in the oral cavity, causing difficulties to rehabilitation. One possible cause of fixture failure could be the poor primary stability achieved in some cases, hence, with an increased bone contact implant stability and survival could be improved. The present report discusses possibilities to use extraoral fixtures with a modified surface structure. Materials and Methods: A new porous surfaced Brazilian extraoral implant (MasterExtra®, Conexão, Sistema de Próteses, São Paulo, Brazil) was used. A bone transplant from the iliac crest was taken to make it possible to insert at least three extraoral implants for an auricle epithesis. Clinical evaluation and resonance frequency analysis (RFA) measurements were performed during the course of the treatment. Results: Eight months after grafting, four fixtures were inserted. Three fixtures were used for connection of an auricular epithesis. RFA measurements did show high initial values and the values remained stable during the course of the treatment and at later checkups. Conclusion: Porous fixture is a good option in areas where the bone is compromised. RFA is a good tool also in the clinical setting to evaluate immediate and long-term stability of extraoral fixtures.
