Impact of Peri-Implant Phenotype on Implant Therapy Outcomes: A 5-Year Cohort Analysis on Soft Tissue-Level Implants.
Article in Journal of clinical periodontology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
objectiveTo investigate the associations between peri-implant phenotype characteristics and long-term outcomes of soft tissue-level implants.
methodsTwenty-five tissue-level implants from a previous controlled clinical trial were evaluated at 1- and 5-year follow-ups after crown delivery. Data included ultrasonographic scans (mucosal thickness and supracrestal tissue height), standardised 2D radiographs, cone beam computed tomography, clinical outcomes (mucosal recession, probing pocket depth, bleeding on probing), patient-reported outcomes and peri-implant health status. Standard logistic and linear regression models were used to analyse associations of implant- and patient-related factors with outcomes, including peri-implant disease status, mucosal recession and marginal bone level (MBL) changes.
resultsFive-year implant survival was 100%, with peri-implant mucositis diagnosed in 36% of the implants. Mean MBL changes from the first to the fifth year was 0.29 ± 0.29 mm. Baseline (pre-surgical) buccal soft-tissue thickness < 1.5 mm (OR: 5.20, p = 0.007) and increased plaque scores (OR: 30.11, p < 0.001) were associated with peri-implant mucositis, whereas buccal bone thickness ≥ 1.5 mm (OR: 0.48, p = 0.039), mucosal thickness around implant (OR: 0.20, p = 0.001) and supracrestal tissue height (OR: 0.50, p = 0.002) emerged as protective factors. Mucosal recession was significantly associated with baseline buccal soft-tissue thickness < 1.5 mm (estimate = 0.27, p = 0.03) and keratinised mucosa width of < 2 mm (estimate = 0.39, p = 0.021). Clinical thresholds associated with long-term peri-implant health were defined as follows: supracrestal tissue height ≥ 2.8 mm, restorative emergence angle ≤ 35.5°, mucosal thickness 1.8 mm and buccal bone thickness 1.5 mm. Patients reported a high overall satisfaction (visual analogue scale: 88.2%). Colour Doppler ultrasonography showed a strong correlation between tissue perfusion and peri-implant disease (r = 0.93, p < 0.001).
conclusionsWithin the limitations of this study, tissue-level implants showed excellent survival rates and patient satisfaction at 5 years. Several peri-implant parameters-such as supracrestal tissue height ≥ 2.8 mm, restorative emergence angle ≤ 35.5° and buccal bone thickness ≥ 1.5 mm-were associated with favourable outcomes. These exploratory thresholds may be considered hypothesis-generating and could help guide future research and clinical monitoring, although validation in larger cohorts is essential.
