Histologic Analysis of Peri-implant Soft Tissue Around External Hexagon and Morse Taper Implant Connections.
Review in Journal of clinical and experimental dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Twenty patients rehabilitated with screw-retained full-arch implant-supported prostheses functioning for at least one year were included. Material and Methods: This clinical study included 20 patients rehabilitated with screw-retained full-arch implant-supported prostheses in function for at least 1 year. Participants were allocated into two groups according to the implant-abutment connection design: external hexagon (EH; n = 10) and Morse taper (MT; n = 10). One peri-implant soft tissue biopsy specimen was obtained from each patient and processed for hematoxylin-eosin staining. Histological evaluation assessed epithelial hyperplasia, epithelial organization, inflammatory infiltrate intensity, and connective tissue fibrosis. Data normality was assessed using the Shapiro-Wilk test. Intergroup comparisons were performed using the Mann-Whitney U test, with a significance level of = 0.05. Results: Mean epithelial hyperplasia scores were 2.0 in the EH group and 1.6 in the MT group (P = 0.690). Mean fibrosis scores were 2.2 (EH) and 2.4 (MT) (P = 0.841). Inflammatory infiltrate scores were 0.4 in the EH group and 2.0 in the MT group (P = 0.095). No statistically significant differences were observed between groups for any evaluated parameter. The combined histologic score also showed no significant intergroup difference (P = 0.222). Conclusions: Within the limitations of this clinical study, peri-implant soft tissue architecture and inflammatory profiles were similar between external hexagon and Morse taper implant-abutment connections in full-arch rehabilitations following at least one year of functional loading.
