Influence of composite resin core buildup translucency on the accuracy of an anterior CAD-CAM bridge fabricated with a digital impression

The use of low translucency reconstructive materials helps to reduce the errors of IOS, and at the same time, appropriate compensation should be used when designing restorations to provide the most accurate results. Clinical Significance: • Composite with high translucency (A3) expressed lower trueness value than one with low translucency (EX). • With a clinically acceptable threshold<50μm, the percentage of points overcoming the threshold was lower in composite group with low translucency (EX). • Appropriate compensation should be applied when designing CAD/CAM restoration to achieve the best results. <b>Key words:</b>Accuracy, intraoral-scanner, digital dentistry, resin composite, bridge prosthesis, CAD/CAM.
