Objective: Fatigue testing of restorative material has been appreciated as an appropriate method to evaluate dental restorations. This study aims to investigate the influence of periodontal ligament (PDL) simulation on fatigue and fracture tests results of zirconia crowns.
Materials And Methods: A standard tooth preparation for all ceramic zirconia crown was made on a typodont mandibular molar.
Objective: This study investigates the influence of the most commonly used indenter materials on fatigue survival and fracture resistance of zirconia crowns.
Materials And Methods: A total of 40 zirconia crowns were prepared using computer-aided design (CAD)/computer-aided manufacturing (CAM) technology: 30 crowns were divided into three experimental groups of 10 specimens and the last 10 specimens acted as the control group. The experimental groups were subjected to chewing simulation with simultaneous thermocycling.
