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

objectivesThis cross-sectional study primarily aimed at investigating the association between the transmucosal emergence geometry and the prevalence of peri-implant diseases in bone- and tissue-level implants (BL/TL). As secondary objectives, the association of other implant-, prosthesis-, and patient-related variables with crestal bone levels (CBL) and additional radiographic findings was explored. MATERIAL AND

methodsPatients with non-molar single tooth implant-supported prostheses were retrospectively identified for inclusion. Clinical and radiographic examinations were performed cross-sectionally to assess peri-implant diseases (peri-implant mucositis, peri-implantitis), emergence geometry at the transmucosal region (profile type, emergence angles at two levels, and prosthetic platform height), and peri-implant radiographic variables, including CBL. Data were analyzed using multivariate regression.

resultsA total of 332 implants (166 BL/166 TL) in 266 patients (60 ± 17 years) were evaluated at a mean of 11.2 ± 1.5 years after implant placement. Peri-implant mucositis was significantly influenced by the crown emergence angle (Level 2; OR = 1.03, p = 0.01) and peri-implantitis by implant diameter (OR = 3.82, p < 0.0001). Crown emergence angles > 30° in BL implants and > 48° in TL implants were consistently associated with peri-implant diseases. Mean CBL was 0.54 ± 1.34 mm, with lower values in TL (-0.24 mm; p = 0.036), females (-0.27 mm, p = 0.029), and implants with greater platform height (-0.175 mm/mm, p = 0.01). Peri-implant sheathing was detected in 13.4% of implants, showing no association with implant-related characteristics.

conclusionsWider crown emergence angles were associated with peri-implant diseases, whereas wider implant diameters were associated with increased peri-implantitis prevalence. TL implant design and greater platform height were associated with reduced CBL.
