人工植牙在骨整合與功能方面已經有成熟的發展。而減少手術次數與植牙療程，並能兼具美觀與
功能的植牙是牙醫師和患者都極於想達成的目標。立即性植牙在文獻上有很多高成功率的報告，而平台轉移設計的植體被列為成功植牙的一項參數。本文提出一個使用有平台轉移設計的植體進行立即性植牙，且利用暫用牙冠塑形軟組織，最後採用黏著式牙冠的病例，在十八個月的追蹤下，觀察這樣的術式與材料的運用，其美觀性的維持與骨整合的情況。且說明另一個常被忽略的參數，即關於搭配植體的支柱套件設計，因為壓縮生物性寬度而造成病骨吸收的問題。

The osseointegration and functional aims of dental implant had been well achieved. How to reduce treatment time and to get esthetic and functional requirements is the premier goal of both the professional and the patient. The high successful rate of immediate implantation had been reported in many literatures, and platform-switching designed abutments have been stated as a parameter of a successful implantation. A case was reported here utilized such designed implant with immediate implantation procedures, modeling soft tissue with a provisional crown,and finished with cemented type prosthesis. After 18 months follow up, the maintenance of appearance and the bony condition are observed for this procedure and materials. We also explained a parameter which usually been overlooked about the abutment assembly which resulted the crest bone resorption due to violate the biological width.
