Treatment Outcome of Extraoral Implants in the Craniofacial Region
MetadataShow full item record
Extraoral implants for the retention of facial prosthesis have been used for better support, stability, and retention. Other than the clinical experiences, treatment outcomes of these prostheses should be evaluated for predicting the long-term success. The aim of this study was to evaluate the survival rates and soft tissue responses of extraoral implants. In total, 52 patients were examined, including 16 with auricular defects, 16 with orbital defects, 13 with nasal defects, and 7 with midfacial defects. Data on implant length and location, radiation-treatment history, systemic diseases, and alcohol and cigarette use were collected and assessed, and data on the health of periimplant soft tissue were recorded for all of the defects. Statistical analyses were performed with t and chi(2) tests and correlation and regression analyses for the determination of the survival rate. According to results, the defect area has a significant effect on success rate. The overall success rate was found highest in the auricular area and least in the midfacial area. The presence of diabetes, alcohol use, and age were found as significant factors for implant loss, whereas smoking and radiotherapy were found as insignificant.
