One-Piece Monolithic Zirconia Single Tooth Implant-Supported Restorations in the Posterior Region: A 1-Year Prospective Case Series 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
objectiveTo assess the clinical, radiographic and patient-reported outcome measures, and the success of screw-retained one-piece monolithic zirconia implant-supported restorations in the posterior region during a 1-year follow-up.
methodsIn a prospective case series, 50 single molar sites in the posterior region of 41 patients with a minimum age of 18 years and sufficient bone volume for placing an implant (≥ 8 mm) and space for an anatomical restoration were included. Following prosthetic-driven digital three-dimensional treatment planning, a tissue-level implant with an internal connection was inserted during a one-stage surgical procedure. Three months later, the implant was restored with a screw-retained one-piece monolithic zirconia restoration. Clinical, radiographic and patient-reported outcome measures, and restoration survival and success according to the modified USPHS criteria were assessed at baseline prior to and immediately after implant placement, and 1-month and 1-year after definitive restoration placement.
resultsAt the 1-year follow-up, 1 implant had been lost (implant survival rate 98%) hence, 49 restorations were evaluated. The restoration survival and success rates were 100% and 98%, respectively. Plaque, calculus, bleeding and suppuration on probing and peri-implant inflammation were absent in most cases. The mean (SD) marginal bone level change between implant placement and the 1-year follow-up was -0.14 mm (0.27) on the mesial and -0.25 mm (0.31) on the distal side. The mean (SD) patient satisfaction (0-10) was 9.2 (0.8) at the 1-year evaluation.
conclusionOne-piece monolithic zirconia implant-supported restorations exhibited favourable outcomes over 1 year in situ.
