Clinical Performance of Long-span Fixed Partial Dentures

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 partially veneered (weaker veneering ceramics in esthetically relevant tooth areas) all-ceramic and classic (completely veneered) metal-ceramic FPDs are lacking. The aim of the current explorative, prospective, randomized, two-arm clinical interventional study is therefore to compare the clinical performance of long-span FPDs (≥ 4 Pontics) made of monolithic / facially veneered zirconium dioxide with a gold standard (completely veneered cobalt chromium (CoCr)-based FPDs). Forty patients will be recruited. Once all inclusion criteria have been established, including the signed informed consent of the patients informed of the content, effort, advantages and disadvantages of the study, patients are…
