In Vitro Three-Dimensional Accuracy of Digital Implant Impressions: The Effect of Implant Angulation.

Purpose: To compare the three-dimensional (3D) accuracy of conventional impressions (CIs) with digital scans (DSs) using an intraoral scanner (IOS) with intraoral scan bodies (SBs) and varying buccolingual interimplant angulations. A secondary aim was to measure the SB machining tolerance and height with and without application of torque.

Materials And Methods: Three master models (MMs) with two implants simulating an implant-supported three-unit fixed partial denture for bone-level implants were used.
