Abstract: Objective Ceramic-laminated veneer has been extensively used in clinics due to its aesthetics and minimally invasive performance. However, its working life and load tolerance remain unclear. This in vitro study aimed to investigate the stress tolerance of different ceramic-laminated veneer designs and materials for incisor restorations. Methods A total of 160 extracted human maxillary incisors were randomly divided into eight groups. Each group was assigned with tooth preparations of the palatal chamfer design or butt joint design, and the materials used were castable glass ceramic or zirconia ceramic. The veneers were bonded to the teeth and subsequently subjected to a maximum loading test on a universal testing machine in different loading angles to check the load tolerance. Results The load tolerance of the butt joint design with castable glass ceramic-laminated veneers was better than that of the palatal chamfer design at both loading angles of 60°and 125°. However, the palatal chamfer design with zirconia ceramic had better concentrated stress distribution. With the 60° loading angle, the palatal chamfer design with zirconia ceramic tolerated the load better than that with the castable glass ceramic. However, they were not significantly different from the butt joint design. At the loading angle of 125°, the zirconia ceramic-laminated veneers showed significantly better load tolerance for both the palatal chamfer design and the butt joint design. Conclusion The palatal chamfer design showed significantly better load tolerance than the butt joint design. Although bonding difficulties were observed in the zirconia ceramic-laminated veneer, the material still had potential clinical application value due to the favorable stress tolerance.
