Study Reveals Influence of Overlay Preparation Designs on Marginal Fit and Fracture Resistance of Advanced Ceramic Restorations

Posted: January 4, 2025
The article explored the impact of three different overlay preparation designs on the marginal fit and fracture resistance of restorations made from advanced zirconia-reinforced lithium disilicate CAD/CAM material. The study found that adjusting the tooth preparation significantly influenced both the fracture resistance and marginal fit of the overlays. Specifically, the group with anatomical occlusal reduction and circumferential shoulder finish line showed the lowest marginal gap, while the group with traditional overlay preparation displayed the highest fracture resistance. These findings highlight the importance of precise tooth preparation in enhancing the performance of ceramic restorations.
