1 · What the graph read from it

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.

2 · The registry

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 retrospectively assess the potential impact of biological and host factors on radiographic bone loss following tissue-level implant placement and prosthetic rehabilitation.

methodsThe University database was reviewed to identify patients treated with tissue-level implants between 2006 and 2020 at the University of Zurich, Switzerland. The study included patients who received screw-retained implant rehabilitations in the posterior area without simultaneous hard- or soft-tissue augmentations and had a follow-up period of at least 12 months. Radiographic measures of marginal bone loss and supracrestal tissue height were conducted using periapical x-rays at different time points. Additional factors analysed included age, gender, smoking status, history of periodontitis, jaw of treatment, type of reconstruction, and prosthetic emergence angle. Associations between marginal bone loss and potential explanatory variables were visualised and analysed. Elastic net regressions were applied to examine potential relationships with marginal bone loss.

resultsA total of 1,479 patients were treated with tissue-level implants. After applying inclusion and exclusion criteria, 106 patients with 106 implants were included in the statistical evaluation after one year (T1, n = 106 implants), and 59 patients with 59 implants were evaluated after three years (T2, n = 59 implants). The mean marginal bone loss was 0.93 mm (SD 0.83) at T1 and 1.04 mm (SD 0.97) at T2. A strong correlation (Spearman) was found between mesial and distal bone loss. Smoking status and the jaw undergoing treatment were associated with bone loss. While these associations were observed in the univariate analysis, a more comprehensive multivariate analysis revealed that these variables had a limited effect on explaining radiographic bone loss.

conclusionsDuring the initial rehabilitation period in tissue-level implants in this cohort smoking status and jaw of treatment seemed to influence early peri-implant bone loss. Further, a strong correlation between mesial and distal MBL was observed. Additional research is required to determine factors contributing to early bone loss following implant-prosthetic rehabilitation.
