AIM AND SCOPE OF THE JOURNAL South Korea were torqued to 15, 20, 35 and 45 Ncm Association of prosthetic features and peri‐implantitis: A cross‐sectional study ... To identify the influence of prosthetic features through a comprehensive analysis with other known risk factors. Thus, each screw was tightened on three occasions to the three insertion torques. The search was augmented by using the option of "related articles" as well as hand searching of references and relevant journals. Purpose: To evaluate the surface threads. Data were analyzed by analysis of variance, Tukey test, and Pearson correlation test (P < .05).

The results, Repeated tightening and loosening of titanium, reduce the incidence of screw loosening. recommended to avoid screw fatigue and fracture. The Journal of Prosthetic and Implant Dentistry is a peer reviewed, open access, e-journal published on behalf of Indian Prosthodontic Society, Kerala State Branch. The purpose of this study was to systematically review clinical studies on the incidence of abutment screw loosening in single-implant restorations with different implant-abutment connection geometries.
