Purpose: The purpose of this study was to measure the tightening torque for dental implant in dental laboratory and to analyze of the effects of different tightening torque.
Materials and Methods: The tightening torque for dental implant in dental laboratory were measured by digital torque gauge. The length of abutment and analog were measured as tightening torque of manufacturer¡¯s instructions and the measured value. And the data were statically analyzed.
Results: The mean tightening torque of implant screw in dental laboratory was 1.563 ¡¾ 0.332 Ncm. The external type implant system of total length were showing no significant differences but the internal type implant system had difference significant (P < 0.05) when compared with tightening torque.
Conclusion: The implant prosthesis should be made under manufacturer¡¯s instructions especially as tightening torque of screw. For the fidelity of implant prosthesis, dental technician should learn how to use the torque gauge.
