Abstract

The aim of this study was to qualitatively evaluate the marginal vertical fit along two different implant-abutment interfaces: (1) a standard abutment on an implant and (2) a computer-aided-design/computer-aided-machine (CAD/CAM) customized screw-retained crown on an implant. Four groups were compared: three customized screw-retained crowns with three different "tolerance" values (CAD-CAM 0, CAD-CAM +1, CAD-CAM -1) and a standard titanium abutment. Qualitative analysis was carried out using an optical microscope. Results showed a vertical gap significantly different from both CAD-CAM 0 and CAD-CAM -1, while no difference was found between standard abutment and CAD-CAM +1. The set tolerance in producing CAD/CAM screw-retained crowns plays a key role in the final fit.

摘要

本研究的目的是定性评估沿两种不同种植体-基台界面的边缘垂直适合性：（1）种植体上的标准基台和（2）种植体上的计算机辅助设计/计算机辅助制造（CAD/CAM）定制螺丝固位冠。比较了四组：三个具有三种不同“公差”值的定制螺丝固位冠（CAD-CAM 0、CAD-CAM +1、CAD-CAM -1）和一个标准钛基台。使用光学显微镜进行定性分析。结果显示，垂直间隙与CAD-CAM 0和CAD-CAM -1均有显著差异，而标准基台与CAD-CAM +1之间未发现差异。制作CAD/CAM螺丝固位冠时设定的公差在最终适合性中起关键作用。
