Clinical Performance of Chairside CAD/CAM Restorations

Status Active, not recruiting

Clinical Trial Summary

This investigation will be a longitudinal clinical trial to study the long-term clinical performance of a resin cement for chairside CAD/CAM restorations. Lithium disilicate chairside CAD/CAM onlays will be adhesively bonded using a selective enamel etch technique with an adhesive. Full contour zirconia crowns will be cemented using a self-adhesive resin cement.

Clinical Trial Description

A wide variety of restorative materials are available for dental restorations. The most popular current materials include glass ceramics and full contour zirconia. Glass ceramic materials are generally preferred for their high translucency mimicking enamel-like esthetics of natural teeth and zirconia is preferred for high strength applications. Both of these materials are available for clinical treatment using chairside CAD/CAM technology. The introduction of an induction sintering oven (SpeedFire oven/Dentsply Sirona) opened the opportunity for chairside full contour zirconia crowns by decreasing sintering times for zirconia to under 30 minutes. 3M Chairside Zirconia (3M) was marketed in 2019 and offers improved esthetics and high strength for monolithic zirconia restorations with an efficient processing time. This investigation will be a longitudinal clinical trial to study the long-term clinical performance of CAD/CAM restorations. Lithium disilicate chairside CAD/CAM onlays (IPS emaxCAD/Ivoclar) will be adhesively bonded using a selective enamel etch technique with a universal adhesive (3M) and a resin cement (3M). Full contour zirconia crowns (3M Chairside Zirconia/3M) will be cemented using a self-adhesive technique. ;
