摘要

上顎前牙的植體贋復是牙科治療中具有挑戰性的術式之一。因為不僅要恢復病人咀嚼的功能，美觀部分也是一個重要考量。上顎前牙區的立即性的植牙方式，近期漸趨流行，因其有許多優點。相較於傳統植牙方式，它更能保留齒槽骨以及牙齦的豐隆度，使植體可以放置在更理想的位置，也因此其上的贗復物能製作得更完善與美觀。另外立即性的植牙方式縮短了整個治療的等待時間，病人心理上會有更高的接受度。本文將蒐集整理近期有關上顎前牙區單顆立即性植牙的研究論文，比較立即性植牙方式與傳統植體治療方式在成功率及植體周圍軟、硬組織表現等的差異，期待能對這個術式有更深入的了解。

Traditional guidelines suggested that 2 to 3 months of alveolar ridge remodeling following tooth extraction and an additional 3 to 6 months of load-free healing after implant insertion are needed for osseointegration to take place. However, nowadays immediate placement and immediate loading do not interfere the process of osseointegration. To achieve osseointegration, the level of micromotion should be kept below a certain tolerance threshold. Upper anterior single immediate placement of dental implants at the time of tooth extraction has yielded favorable and predictable results. Advantages include better bone and soft tissue preservation, reduced postoperative pain, significant reduction of clinical chair time, and greater patient acceptance. Apart from time gain, another rationale for immediate implantation and provisionalization is the potential to maximally preserve hard and soft tissues, which may be beneficial to the esthetic treatment outcome. The aim of the present literature review was to evaluate the outcome of immediate implantation and provisionalization to replace single maxillary tooth at the esthetic zone.
