Abstract

The Osseointegrated Implant System was indispensable for many kinds of parts, such as transmucosal meso-structure or superstructure. They were fastened by a screw. The fastening force had an influence on the load of the bite force, accuracy of the superstructure, and prognosis of the implant. Therefore, in this study, we measured the optimum fastening torque force, by using a torque wrench.
The results obtained were as follows:
1. The clinical optimum fastening torque force for the impression post, IME, and superstructure was 4.5 Ncm.
2. The newly devised measuring system was easy to use and repeatable. It should be valuable for measuring the fastening force for various implant systems.
