Purpose: Misfit of superstructure-supported osseointegrated implants causes adverse stress in the prosthesis, components, and surrounding bone. A passive fit of the implant-supported prosthesis is essential for successful long-term osseointegration. Various clinical methods for evaluating the fit of implant-supported prostheses have been suggested. However, the methods have little scientific evidence to determine the acceptable fit. The present study evaluated the misfit of implant-supported prostheses by measuring the rotational angle/tightening torque in screwing the prosthesis on master models.<BR>Materials and Methods: Twenty-four implant-supported prostheses (3 single standing, 20 fixed partial, 1 full bridge) of fourteen patients were evaluated using a custom-made rotational angle/ tightening torque measuring apparatus on the master models. The influence of the order of tightening and unit number on the value was also evaluated.<BR>Results: The mean of the rotational angle/tightening torque was 2.6 (SD: 0.6) degree/Ncm in all prostheses. The value was significantly higher than that in the abutment screw as a control. The order of tightening and unit number did not significantly affect the values.<BR>Conclusions: The results suggest that measurements of rotational angle/tightening torque be useful for evaluating the fit of implant-supported prostheses. Misfit of the prostheses was below the level of acceptable fit.
