3 Clinical Trials for Various Conditions
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.
This is a prospective observational clinical trial to evaluate the clinical performance of the Cerec Tessera prosthetic assembly on implants restored with chairside CAD/CAM-generated crowns. This investigation is intended as a Post Market Clinical Follow-up study for the product Cerec Tessera and its prosthetic assembly for implants, which will serve as a life-cycle approach to safety, backed up by clinical data and post-market monitoring.
The purpose of this research study is to identify reasons that cause an all-ceramic bridge to fracture which include the thickness of the bridge material, the type of bridge material and the bite force of the person. This all-ceramic bridge will be compared to a metal-ceramic bridge. The investigators are conducting this study so we can make bridges which can withstand forces in the mouth which tend to break them. The overall objective of this research is to analyze how properties of ceramic materials and different forces in the mouth interact with each other to affect the longevity of these bridges. These include fracture toughness, elastic modulus of ceramic layers and supporting substrate, core thickness, connector height, wear, loading orientation, and maximum clenching force.
