Five-Year Results of One-Piece Zirconia Oral Implants Supporting Three-Unit Fixed Dental Prostheses.

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
objectivesThe purpose of the present prospective case series was to investigate the clinical and radiological outcome of one-piece zirconia implants fabricated from 3Y-TZP with a moderately roughened endosseous surface (Sa = 1.24 μm) to support three-unit fixed dental prostheses (FDP) after five years in function. MATERIALS AND
methodsTwenty-seven patients received a total of 54 implants in a one-stage surgery with immediate provisionalization. Peri-implant bone loss was assessed using standardized radiographs. Additionally, soft-tissue parameters were analyzed. Statistical analyses were conducted using linear mixed regression models and Wilcoxon Signed Rank tests (p < 0.05). All patients participated in an annual maintenance program.
resultsEighteen implants were lost up to the 5-year follow-up, resulting in a cumulative survival rate of 66.67%. The mean marginal bone loss of the remaining implants amounted to 1.89 mm. Probing depth, clinical attachment loss, and bleeding on probing increased from prosthesis insertion to the 5-year follow-up, while the plaque index showed no significant changes during the same period.
conclusionsThe investigated one-piece zirconia implant showed low survival rates as compared to previously reported survival rates of one-piece zirconia or two-piece titanium implants. Implant failure was attributed to peri-implantitis, leading to the necessity of implant removal. The implant is not commercially available.
