The UCLA abutment has been used over the past 4 years in the restoration of osseointegrated implants. The design of the abutment allows fabrication of the restoration directly to the implant fixture, bypassing the transmucosal abutment cylinder. This technique is valuable in overcoming problems of limited interocclusal distance, interproximal distance, implant angulation, and soft tissue response. Another major advantage with the UCLA abutment is that of improved esthetics. After treatment of 46 patients with 118 UCLA abutments, the 4-year success rates are 95.8%.
在过去四年中，加州大学洛杉矶分校（UCLA）基台一直用于骨结合种植体的修复。该基台的设计允许直接在种植体固定装置上制作修复体，绕过穿龈基台柱。这项技术对于克服牙合间距离有限、邻间距离、种植体角度和软组织反应等问题很有价值。UCLA基台的另一个主要优点是美观性得到改善。在对46例患者使用118个UCLA基台进行治疗后，4年成功率为95.8%。
