The Tübingen polycrystalline alumina implant utilizes bony apposition as the method of stabilization. Its cylindrical configuration allows the implant site to be prepared by use of ultra-low-speed drills. This study focused on the use of the implant as a single-tooth, free-standing device. Thirty patients were selected. Devices were followed for five years. The implants were placed in one of two applications: immediate extraction site or healed edentulous ridge. A simple purse-string suture technique was used for closure. Periodic observations were recorded. Of the 30 planned implants, all have been completed to date. Twenty-five of the 30 have been considered successful. Twenty-three of the 25 successes were from the immediate extraction group. Only 2 of 5 were successful in the healed ridge group. Due to the structural requirements of the Tübingen implant, its size makes it usable only in wider-than-average edentulous ridges. The success rate was 83.3%, and for those devices placed in immediate extraction sites, a success rate of 92% was recorded.
图宾根多晶氧化铝种植体采用骨附着作为稳定方法。其圆柱形结构允许使用超低速钻头制备种植部位。本研究重点关注该种植体作为单颗独立装置的使用情况。选择了30名患者。对种植体进行了五年的跟踪。种植体有两种植入方式：即刻拔牙位点或愈合无牙嵴。采用简单的荷包缝合技术进行创口闭合。记录定期观察结果。在计划植入的30颗种植体中，目前均已完成植入。30颗中有25颗被认为成功。25颗成功种植体中有23颗来自即刻拔牙组。愈合无牙嵴组5颗中仅有2颗成功。由于图宾根种植体的结构要求，其尺寸使其仅适用于比平均宽度更宽的无牙嵴。成功率为83.3%，对于那些植入即刻拔牙位点的种植体，记录的成功率为92%。
