Abstract
Purpose: In this study, the loosening torque test was conducted with three implant products that are produced, approved and sold in Korea, which are manufactured in different fixture and abutment tightening methods (internal submerged type, internal morse taper type, and external type) to examine the loosening torque of the screw according to the method of tightening the implant fixture and abutment.
Methods: In the loosening torque test, the three types of fixtures and abutments with different tightening methods were tightened by rotating them clockwise with a 30 N force using a driver equipped with an electric torque meter. The results of the test are as follows.
Results: The loosening torque values of the internal submerged type, internal morse taper type and external type
implants were 24.10 0.742 N , 29.10 1.710 N , and 26.60 1.636 N , respectively.
Conclusion: The screw loosening torque values of the three fixture and abutment tightening methods were analyzed via Kruskal Wallis test layout, and they were significantly different (p<0.05).
