Despite significant advances in dental therapeutics, there are patients for whom no reasonable treatment is available that will reliably restore or maintain their existing dentition. The causes of future edentulism include advanced caries, failing root canal therapy, inadequate numbers of teeth to support a fixed prosthesis, untreatable periodontal disease, or a history of failed previous rehabilitations. For these patients, dental implants may provide a more predictable future than retention of their remaining teeth. It is proposed that transitional fixed prostheses designed specifically for a patient with terminal dentition offer the advantage of maintenance and development of proper gingival esthetics with improved function. Prior to implant placement, the gingival frame is established, enhancing the overall appearance of the final, full-arch implant rehabilitation. The specific prosthodontic and surgical techniques required for successful treatment of these patients are presented.
尽管牙科治疗技术取得了重大进展，但仍有一些患者无法获得合理的治疗方法来可靠地修复或维持其现有牙列。未来无牙的原因包括严重龋齿、根管治疗失败、支持固定修复体的牙齿数量不足、无法治疗的牙周疾病或既往修复失败史。对于这些患者，种植牙可能比保留剩余牙齿提供更可预测的未来。有人提出，专为晚期牙列患者设计的过渡性固定修复体具有维持和改善牙龈美学以及提高功能的优势。在植入种植体之前，先建立牙龈框架，以增强最终全牙弓种植修复的整体外观。本文介绍了成功治疗这些患者所需的特定修复和外科技术。
