Clinical Study of a 3D Shaded Zirconia for Chairside CAD/CAM Restorations
brief summary
This investigation will be a prospective, longitudinal clinical trial to study the clinical performance of a new monolithic, 3D shaded zirconia material for computer assisted design and computer assisted machining for chairside restorations. The restorations will be evaluated for a period of up to five years. The study is called Clinical Study of a 3D Shaded Zirconia for chairside computer assisted design and computer assisted machining (CAD/CAM) chairside restorations intended to be part of the validation plan and post market follow-up of the following products: CEREC Cercon 4D, Calibra Universal +, and Prime and Bond Active.
detailed description
The primary aim is:
▪ Evaluate the longitudinal clinical performance of 3D shaded zirconia onlays, crowns, and fixed partial denture (FPD) over five years of clinical service. The restorations will be evaluated with modified FDI criteria for maintaining their esthetic, functional and biological properties.
The secondary aims are:
* Evaluate the resistance to material chipping and fracture of reduced thickness zirconia chairside computer assisted design and computer assisted machining (CAD/CAM) onlays, crowns, and fixed partial dentures (FPDs). * Evaluate the short-term post-operative sensitivity associated with cementation techniques using a self-adhesive, universal resin cement and a selective etch/universal bonding agent with a universal resin cement.
