Abstract

The influence of abutment angulation on implant impression accuracy by comparing Closed Tray and Open Tray techniques in a clinical setting is of interest to dentists. Hence, a prospective cross-sectional analysis was conducted on 60 patients receiving implant-supported prostheses, stratified by abutment angulation (0°C, 15°C and 30–45°C). Impressions were made using polyvinyl siloxane and accuracy was quantified via mean MM discrepancy and procedural performance scores. The Open Tray technique demonstrated superior dimensional fidelity (mean discrepancy = 0.46 mm) versus the Closed Tray (0.72 mm), with significantly higher rates of clinically acceptable impressions and procedural efficacy. Logistic regression identified procedural proficiency as a strong predictor of impression precision. These findings underscore the diagnostic superiority of the Open Tray technique, particularly in angulated scenarios, reinforcing its value in enhancing prosthetic accuracy and clinical predictability.
