Official title
Clinical Performance of Alternative Preparation Designs for Chairside CAD/CAM Fabricated Advanced Lithium Disilicate EndoCrowns
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
