Clinical Performance and Accuracy of Healing Abutment With Scan Peg for Single Posterior Implant-supported Restorations

Clinical Performance and Accuracy of Healing Abutment With Scan Peg for Single Posterior Implant-supported Restorations

The aim of this randomized clinical trial is to evaluate the clinical performance through prosthodontic, periodontal and radiographic evaluation of single screw-retained implant-supported restorations fabricated by intraoral scanning of healing abutment with scan peg in comparison to scan body
