摘要

隨著科技的進步，植牙漸漸普及，植牙帶給病患另一種治療選擇。近年來有關植牙的報告也愈來愈多，回顧文獻植牙的成功率大多在九成以上，雖然如此，還是有植牙失敗的例子。為了追求醫療品質的提升，牙醫師必需更了解所有可能造成植體失敗的原因，在植牙前仔細評估並加以避免可能造成植體失敗的各種情形，以達到更高的成功率。本文提出一植牙失敗案例，並探討造成失敗的原因以及失敗後之處理方式。

Through progress in science and technology, implants have gradually become more popular. This gives patients another treatment choice. There are increasing numbers of reports on implants in recent years. High success rates exceeding 90% were reported in almost all of these documents. Even so, implant failure still occurs. In order to pursue improvements in medical quality, dentists must understand all factors which can cause implant failure and assess them carefully before implantation. This report investigates the reasons for failure in this case and discusses the subsequent management. After our evaluation, the major reason for the implant failure may be due to the apical lesion of the central incisor close to the implant. We cannot augment the ridge as we expected because of the thin gingival biotype of the patient. Therefore, in order to achieve the esthetic result, we chose non-resorbable hydroxyapatite to augment the ridge. As for the prosthetic part, we restored the edentulous ridge by cantilever bridge, the result turned out to be acceptable.
