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

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo 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
methodsHigh-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.
resultsTwenty-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.
conclusionsMonolithic 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.
