The study was done to assess the implant-abutment interface static compressive. strength of three design types and implant-abutment connection failure style.
The implants at 306 with respect to the y-axis were aligned using a stainless steel holding device. Twenty specimens from each system totaled 60 total. A unidirectional vertical piston in a computer-controlled universal testing machine (MTS 810) generated static compression loading until failure. Specimens were macroscopically examined for fracture of the screw and implant, abutment looseness, and longitudinal displacement. Analysis of variance was used to analyze the data (ANOVA).
The screw-vent system had a mean compressive strength of 335.6 22.7 psi for the Unipost system, 384.3 37.1 psi for the screw-vent system, and 245.3 25.4 psi for the ITI-1 piece abutment connection.
The connection between the Unipost implant and abutment showed a statistically significant variation.
本研究旨在评估三种设计类型的种植体-基台界面静态抗压强度以及种植体-基台连接失败方式。
使用不锈钢固定装置将306颗种植体沿y轴对齐。每个系统取20个样本，共60个样本。在计算机控制的万能试验机（MTS 810）中，通过单向垂直活塞产生静态压缩载荷直至失败。对样本进行宏观检查，观察螺钉和种植体的断裂情况、基台松动情况以及纵向位移。采用方差分析对数据进行分析（ANOVA）。
Unipost系统的螺钉-通气系统平均抗压强度为335.6±22.7磅力/平方英寸，螺钉-通气系统为384.3±37.1磅力/平方英寸，ITI-1件式基台连接为245.3±25.4磅力/平方英寸。
Unipost种植体与基台之间的连接在统计学上存在显著差异。
