Clinical Performance of Long-span Fixed Partial Dentures

| Summary | Tooth-coloured fixed restorations are becoming increasingly popular with patients and dentists. If high-strength all-ceramics such as zirconia are used as the restoration material, a maximum of two adjacent missing teeth can be replaced with the aid of fixed partial dentures (FPDs). For the replacement of a missing anterior or posterior tooth by FPDs, a very good clinical performance similar to that of metal-based, ceramic-veneered restorations can be expected. However, evidence-based statements on the clinical performance of long-span all-ceramic FPDs are difficult because there are only very few studies on this topic, which are also inhomogeneous with regard to the study conditions. Randomized studies to compare monolithic (consisting only of the high-strength framework material) or part |
