Effect of Screw Channel Angulation on Reverse Torque Values of Dental Implant Abutment Screws

Abstract

Introduction: Angled screw channels were developed to maintain screw access/retrievability when implant position would otherwise preclude in-line screw channels. Implant manufacturers recommend torque values to achieve desired preload and clamping force of restorative components. However, the effect of angled screw channels on achieved insertion torque has been minimally researched. Purpose: To compare the reverse torque values of abutment screws tightened from three different angles.
