To present a simplified method for assessment of precision of fit between screw-retained frameworks and supporting implants in clinical situations.
Torque-angle signature analysis is a method for analysis of tension within a joint. The OsseoCare device developed by Nobel Biocare was utilized for the tests. Three titanium frameworks were fabricated on the same master cast according to 3 different methods: (1) 1-piece casting, (2) the CNC (computer numeric controlled) method, and (3) the CTiP (Cresco Ti Precision) method. These frameworks were used to test the device and indirectly the application of the torque-angle signature analysis technology.
The frameworks fabricated according to the CNC and CTiP methods demonstrated OsseoCare tracings similar to the reference models of passively fitting joints, while the 1-piece cast framework did not.
According to this pilot study, the OsseoCare device and torque-angle signature analysis proved to be feasible for clinical assessment of fit between frameworks and supporting implants.
介绍一种在临床情况下评估螺丝固位支架与支持种植体之间适配精度的简化方法。
扭矩-角度特征分析是一种分析关节内张力的方法。采用诺贝尔生物公司研发的OsseoCare装置进行测试。根据三种不同方法在同一母模上制作了三个钛支架：（1）整体铸造，（2）计算机数控（CNC）方法，（3）CTiP（Cresco Ti Precision）方法。这些支架用于测试该装置，并间接测试扭矩-角度特征分析技术的应用。
根据CNC和CTiP方法制作的支架显示出与被动适配关节的参考模型相似的OsseoCare描记，而整体铸造的支架则没有。
根据这项初步研究，OsseoCare装置和扭矩-角度特征分析被证明对于临床评估支架与支持种植体之间的适配是可行的。
