Effect of length of LOCATOR abutment and cement type on retention to intraradicular dentin in overdentures.

Statement Of Problem: Limited information is available on the effect of LOCATOR abutment length and luting cement type on retention to intraradicular dentin in overdentures.

Purpose: The purpose of this in vitro study was to evaluate the effect of the length of a commercially available LOCATOR abutment and cement type on retention in the root canal.

Material And Methods: Eighty LOCATOR abutments with a standard length of 6 mm were obtained.

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.
