Study Summary
This investigation will be a longitudinal clinical trial to study the association of preparation design on the internal and marginal adaptation of the resulting restorations and the long-term clinical performance of chairside CAD/CAM endocrown restorations. Advanced lithium disilicate chairside CAD/CAM endocrowns (CEREC Tessera/Dentsply Sirona) will be adhesively bonded using a selective enamel etch technique with a universal adhesive (Prime and Bond Elect/Dentsply Sirona) and a dual cure resin adhesive cement (Calibra Ceram/Dentsply Sirona). All restorations will be followed over five years of clinical service.
Primary Outcome
Restoration failure is scored by visual loss of the crown from the tooth requiring replacement of the study crown with a new crown at any time between delivery and three years.
