Moving Beyond Crunch-the-Crown Testing Clinical Failure

Abstract

Traditional fracture tests of single unit prostheses are inappropriate, since they do not create failure mechanisms seen clinically. Validated tests are needed to elucidate the role(s) metal copings, cement systems, bonding and occlusion play in the success of fixed prostheses as well as make meaningful comparisons possible among novel metal and ceramics substructures. Research over the past six years has shown that crack systems mimicking clinical failure can be produced in all-ceramic restorations under appropriate conditions.
