Combined Effect of Abutment Height and Restoration Emergence Angle on Peri-Implant Bone Loss Progression: A Retrospective Analysis.
Article in Clinical oral implants research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07637864 (Association Between Buccal Prosthetic Profile Angles at Different Supraplatform Zones and Peri-Implant Tissue Remodeling Around Bone-Level Implants), which is not on this map. Cited by 14 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
introductionThis study aimed to investigate the combined effect of trans-mucosal abutment height (TmAH) and restorative emergence angle (REA) on marginal bone loss (MBL) around bone-level implants.
methodsImplant radiographs 12-18 months after crown placement (T0) and at least one year later (T1) were retrospectively analyzed. Sites were separated into four groups: Long/Narrow-Angle (LN) with TmAH > 2 mm and REA < 30°, Long/Wide-Angle (LW) with TmAH > 2 mm and REA ≥ 30°, Short/Narrow-Angle (SN) with TmAH < 2 mm and REA < 30°, and Short/Wide-Angle (SW) with TmAH < 2 mm and REA ≥ 30°. MBL was calculated, and multiple linear regression analysis was performed to control for patient-level and implant/prosthesis-level factors.
results192 implants pertaining to 119 patients were included. Group significantly influenced MBL experience (p < 0.001). Group SW experienced on average 0.48 mm (95% CI: 0.25-0.71, p < 0.001), 0.43 mm (95% CI: 0.18-0.68, p = 0.001), and 0.25 mm (95% CI: 0.00-0.45, p = 0.013) greater MBL compared to Groups LN, LW, and SN, respectively. Group was also a significant factor impacting the development of peri-implantitis (p = 0.041), with Group SW displaying a roughly 4× greater likelihood of having peri-implantitis (PI) diagnosed compared to Groups LN (OR: 4.04; p = 0.091) and LW (OR: 4.19; p = 0.013). Every 1 mm increase in TmAH significantly decreased the likelihood of MBL > 0 mm (OR = 0.63; p = 0.003).
conclusionsAbutment height > 2 mm may play a role in reducing PI and MBL related to ≥ 30° REA around bone-level implants. REA was found to only be a significant factor when TmAH is less than 2 mm.
