Abstract

Small defects in dental crowns due to the manufacturing or physiological/non-physiological stress in patients’ mouth can result in failure of restorations and sometimes even lead to the extraction of the tooth itself. If those microcracks can reliably be detected, defective crowns can be sorted out or be repaired in case of fatigue damage. Currently there is no non-destructive method to visualize microcracks within Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM)-materials, neither for dentists nor manufacturers. Therefore, eight different monolithic CAD/CAM-materials were inspected by different Optical Coherence Tomography (OCT) systems before and after mouth-motion-simulation. All OCT devices were suitable to visualize microcracks in the crowns. However, differences regarding parameters and CAD/CAM-materials were detected.
