Soft tissue grafting at immediate implants: does it protect the buccal plate?
Trial report in Evidence-based dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
a commentary onJung M, Tran D, Chang CC, Kim SK, Tsukiboshi Y, Min S, Ayilavarapu S, Lee CT. Volumetric buccal bone alterations at immediate implant sites with or without soft tissue augmentation: A 6-month assessment. J Periodontol. 2026;97:220-33. https://doi.org/10.1002/jper.11381 .
designThis was a secondary analysis of cone-beam computed tomography (CBCT) and scanned model data from a registered randomised controlled trial evaluating immediate implant placement with or without soft tissue augmentation CASE SELECTION: Forty-five patients requiring extraction of a single maxillary anterior or premolar tooth followed by immediate implant placement were included. Participants were allocated to one of three groups: immediate implant with subepithelial connective tissue graft, immediate implant with acellular dermal matrix, or immediate implant alone. In all groups, the gap between the implant and the alveolar bone was filled with bovine bone material and a collagen dressing was placed. DATA ANALYSIS: CBCT scans were taken before extraction and 6 months after immediate implant placement. The scans were superimposed to assess three-dimensional volumetric and two-dimensional linear buccal bone dimensional changes. The buccal region was divided into coronal, middle and apical thirds. Volumetric bone loss was calculated in absolute and relative terms. Linear horizontal and vertical bone changes were also assessed. Measurements were carried out by a calibrated blinded examiner. Statistical analysis included ANOVA or Kruskal-Wallis tests, linear regression analysis to explore associations between clinical factors and volumetric bone change, and Pearson correlation coefficients to compare 3D and 2D measurements.
resultsThere was no statistically significant difference in volumetric buccal bone loss between the three groups at 6 months. The greatest loss occurred in the coronal third, with mean volumetric reductions of -14.99 ± 4.29 mm³ in the connective tissue graft group, -13.60 ± 3.97 mm³ in the acellular dermal matrix group, and -12.58 ± 4.09 mm³ in the control group (p = 0.286). Thick bone morphotype was associated with greater absolute volumetric bone loss. Correlations between 3D and 2D measurements varied between anatomical segments.
conclusionSoft tissue augmentation using either a subepithelial connective tissue graft or acellular dermal matrix did not significantly reduce buccal bone dimensional loss at immediate implant sites after 6 months. Linear measurements may not represent fully volumetric buccal bone changes.
