Causes of Chipping/Fracturing in Zirconia Based All-ceramic Restorations

Abstract: To determine, in vitro, causes of chipping/fracturing in zirconia based all-ceramic restorations. Theories tested: inadequate porcelain support due to uniform thickness copings, and thermal mismatch between substructure and porcelain. Dies and porcelain burnout shells designed on Solidworks for milling and 3D printing.  90 crowns will be cycled at constant forces and cycles, examined and stair-cased until chipping or fracturing occurs.  We anticipate crowns with unsupported porcelain and “fast cooled” crowns to demonstrate early failure.    Bio: Thomas Suranyi was born and raised in Montreal, Canada.  He completed his Bachelors of Arts at the University of Rochester, NY, with a double major in Chemistry (cum laude)/History (cum laude) and a minor in Biology.  In 2007 and 2008 Dr. Suranyi earned both his D.D.S. and A.E.G.D. Certificate from Columbia University’s College of Dental Medicine, NYC.  Currently, he is a 2nd year Prosthodontic resident at the University of North Carolina at Chapel Hill.
