Effect of Single Off-Axis Implant Placement on Abutment Screw Stability Under Lateral Loading.

Purpose: The aim of this study was to evaluate the effect of off-axis implant placement in relation to the prosthetic crown on abutment screw loosening under different directions of twisting moments.

Materials And Methods: Twenty-one implant assemblies were divided equally into three groups (n = 7). Each assembly consisted of an internal-octagon implant measuring 4.

The effects of two torque values on the screw preload of implant-supported prostheses with passive fit or misfit.

Purpose: To determine the effect of increased torque of the abutment screw and retorquing after 10 minutes on implant-supported fixed prostheses.

Materials And Methods: Two strain gauges (SGs) were attached to four implants stabilized on an acrylic resin mandible. Four implant-supported frameworks were constructed to represent passive fit (PF) and different amounts of misfit (MF1, MF2, and MF3).
