Clinical Performance: A Reflection of Damage Accumulation

Abstract

Clinical performance of an prosthesis is directly dependent on damage introduced during fabrication and during fatigue loading associated with function. The relation between shaping damage and fatigue damage on clinical performance of all-ceramic dental crowns was investigated. Materials used commercially for all-ceramic crowns and investigated in this study included a series of different microstructures of machinable glass ceramics (Corning), aluminas and porcelains (Vita Zahnfabrik), and zirconias (Norton).
