Abstract
Purpose: The purpose of study was to analyze the influence on the implant design, density of cancellous bone and thickness of cortical bone to the implant primary stability.
Materials and Methods: A total of 144 implants (4.0×10 mm) were installed in 24 artificial bones. Implants were divided into 3 groups. Artificial bones were divided into 4 groups.
Results: There was statistical significance among ITV, ISQ, PTV (p＜0.05). Element that effects to primary stability, D3 bone has been above D4 bone. Primary stability has been influenced according to existence of cortical bone and has shown a great level as cortical bone is 2 mm. The B implant has shown the highest primary stability level among the three types of Implants: macro thread ＞ double micro, macro and micro thread ＞ macro and micro thread. The degrees of the factors affecting primary stability: implant fixture＞ cortical bone＞cancellous bone type.
Conclusions: There has been a close correlation among the results of three stability measuring devices (ITV, ISQ, PTV). The fixture types of Implant have been the biggest influences to primary stability among all the factors.
