Three-unit posterior monolithic fixed dental prostheses made from high-translucent shade-graded zirconia: 3-Year results from a prospective clinical pilot study.

Objectives: To assess the clinical performance of tooth-supported 3-unit fixed dental prostheses (FDPs) made from shade-graded monolithic 5Y-PSZ (partly stabilized zirconia) zirconia in terms of survival rate and the quality of restorations based on modified FDI criteria over three-years.

Materials and methods: High-translucent shade-graded monolithic zirconia (Lava Esthetic, Solventum Dental Solutions) was used to manufacture maxillary or mandibular three-unit FDPs in the posterior region (N = 22) employing subtractive milling system (Amann Girrbach). All FDPs were bonded with a universal resin cement (Rely X Universal, Solventum Dental Solutions) and evaluated 4 weeks after cementation (baseline) and after 1, 2, and 3 years. The primary objective was to assess the survival and complication rates of the restorations. Furthermore, the quality of the restorations was evaluated based on selected and modified FDI (World Dental Federation) criteria, which encompass functional, aesthetic, and biological parameters. FDI criteria were analyzed using the Fisher-Freeman-Halton exact test.

Results: Twenty-one patients were examined at 1 year, 2 years, and 3 years. The survival rate was 100%. No mechanical complications were observed. A total of 3 biological complications occurred. These were successfully managed without any residual functional impairment. All FDI criteria were found to be clinically acceptable or better.

Conclusions: Monolithic shade-graded zirconia FDPs demonstrated 100% survival at 3 years with a low complication rate.

Clinical relevance: Fixed 3-unit FDPs made of high-translucent monolithic zirconia might be a viable treatment option in the posterior region, preventing the chipping phenomenon and providing favorable aesthetics while allowing for an efficient digital workflow.
