Evaluation of Marginal Adaptation and Internal fit of CAD/CAM Restoration Using five Different Digital Protocols an in Vitro Study

Abstract

During the past years’ new digital technologies invaded the dental practice in various ways especially the CAD/CAM technology which showed a great success: offering an escape from the conventional laboratory hassle, improving quality of dental restoration, raising new indications regarding restoration designs, providing new materials and digital workflows. This revolution of CAD/CAM technology raised the question: is there a great difference in terms of marginal and internal adaptation and quality of restorations conducted through chair-side and in-laboratory digital workflows using different scanners, software’s and milling machines. The aim of this in-vitro study was to assess and evaluate marginal and internal fit of zirconia reinforced lithium silicate ceramic restorations using different digital protocols: 1. CEREC Omnicam + CEREC premium SW + MCXL (DENTSPLY SIRONA). 2. CEREC Omnicam + CEREC connect SW + MCXL (DENTSPLY SIRONA). 3. CEREC Omnicam + CEREC connect SW + MCX5 (DENTSPLY SIRONA). 4. CEREC InEos X5 + InLab SW 15 + MCXL (DENTSPLY SIRONA). 5. CEREC InEos X5 + InLab SW 15 + MCX5 (DENTSPLY SIRONA).
