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 chi2 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.
用于面部假体固位的口外种植体已被用于提供更好的支撑、稳定性和固位。除了临床经验外，还应评估这些假体的治疗效果以预测长期成功率。本研究的目的是评估口外种植体的生存率和软组织反应。总共检查了52例患者，包括16例耳缺损患者、16例眼眶缺损患者、13例鼻缺损患者和7例面中部缺损患者。收集并评估了种植体长度和位置、放射治疗史、全身性疾病以及饮酒和吸烟情况的数据，并记录了所有缺损周围种植体软组织的健康数据。进行t检验和卡方检验以及相关性和回归分析以确定生存率。根据结果，缺损区域对成功率有显著影响。发现总体成功率在耳部区域最高，在面中部区域最低。发现糖尿病、饮酒和年龄是种植体丢失的重要因素，而吸烟和放疗则被认为不显著。
