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.

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.

Abstract

backgroundThe stability of soft and hard tissues surrounding the implant is not only a matter of aesthetics, but also affects the long-term stability of the implant. The present study was to explore the influence of buccal mucosa width/height (W/H) ratio, emergence profile and buccal bone width on peri-implant soft and hard tissue changes in the posterior region.

methodsFifty-eight posterior implant restoration cases were recruited in this study. Evaluations were performed at the time of restoration placement (T0), and 1 year later (T1). Buccal mucosa width (BMW), buccal bone width (BBW), implant buccal inclination angle, and emergence angle were evaluated. The variables that may affect buccal mucosa recession (MR) as well as vertical bone loss (VBL) were analyzed.

resultsThe BMW at baseline was 2.93 ± 1.01 mm. The BBW at baseline was 1.50 ± 0.82 mm. The buccal mucosa W/H ratio at 1 year (1.23 ± 0.38) was significantly lower than that at baseline (1.42 ± 0.45). Buccal MR was - 0.22 ± 0.47 mm while VBL was 0.81 ± 0.80 mm. The correlation between MR and initial BMW (r=-0.381), initial W/H ratio (r=-0.422), BBW (r=-0.290) was statistically significant. The correlation between VBL and initial BMW (r=-0.421), initial W/H ratio (r=-0.305), implant buccal inclination angle (r = 0.507), BBW (r=-0.556) was statistically significant.

conclusionsWithin the scope of this study, implant sites in the posterior region presenting a thin BMW, a thin BBW, and a small W/H ratio are more prone to exhibit buccal mucosa recession and vertical bone loss.
