10-Year Performance of Veneered CAD/CAM versus Conventional Single-Span and Multi-Span Fixed Partial Dentures

Silvia Brandt, Jan-Tobias Süss, Hans-Christoph Lauer and Jan Brandt

Aim: The aim of the present study was to compare the survival rates of different materials for fixed partial dentures (FPDs).

Materials and Methods: A total of 547 FPDs made of different materials delivered to 319 patients were studied retrospectively with a mean observation time of 9.3 years. Cast-metal, metal-ceramic, and all-ceramic FPDs were included in the study and compared.

Results: The 10-year survival rate for cast-metal FPDs was 92.7%, for metal-ceramic FPDs, 76.2%, and for allceramic FPDs, 88.2%. No significant findings were reported regarding FPD materials and long-term survival rates.

Conclusion: Unlike in previous studies, no significant difference between the survival rates of all-ceramic FPDs and FPDs made of other materials was found. These results may be due to modern manufacturing methods of FPD frameworks — in particular CAD/CAM technology, which facilitates optimized framework designs.
