Chairside CAD/CAM materials. Part 3: Cyclic fatigue parameters and lifetime predictions

Clinical indications of dental restorative materials are traditionally based on their mechanical strength, by relating experimental fracture loads to load ranges occurring intraorally. This concept is flawed in many aspects [1], yielding very arbitrary safety limits for clinical fracture. Also, ranking materials according to their strength as means to predict clinical performance disregards important underlying chemical and mechanical fatigue degradation processes that take place in the oral environment.
