DOI: 10.11607/ijp.3853, PubMed ID (PMID): 26340017Pages 538-541, Language: EnglishHogg, Wiebke Semper / Zulauf, Kris / Mehrhof, Jürgen / Nelson, KatjaThe influence of repeated system-specific torque tightening on the position stability of the abutment after de- and reassembly of the implant components was evaluated in six dental implant systems with a conical implant-abutment connection. An established experimental setup was used in this study. Rotation, vertical displacement, and canting moments of the abutment were observed; they depended on the implant system (P = .001, P .001, P = .006, respectively). Repeated torque tightening of the abutment screw does not eliminate changes in position of the abutment.
