Effect of autogenous tooth vs. autogenous bone grafts on periodontal phenotype around immediate implants: A randomized clinical trial.
Article in Journal of advanced periodontology & implant 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
Background: Immediate implant placement can result in a horizontal defect between the implant and alveolar bone, potentially affecting osseointegration and esthetic outcomes. Grafting this space supports bone regeneration. This study compared the effectiveness of autogenous tooth-derived and autogenous bone grafts for horizontal gap augmentation in the maxillary anterior region. Methods: This parallel-arm randomized, single-masked clinical trial enrolled patients attending the Tabriz University of Medical Sciences School of Dentistry, who were candidates for immediate implant placement in the maxillary anterior region. After implant placement, the control sites (n=11) received autogenous bone grafts. In contrast, the intervention sites (n=11) received autogenous dentin grafts to fill the horizontal gap between the implant and the buccal wall (jumping gap). A connective tissue graft was subsequently placed in both groups to enhance buccal soft tissue. Buccal bone thickness (measured 2 mm and 5 mm below the marginal crest) and soft tissue thickness were measured at two points at the time of surgery and again six months postoperatively. Data were analyzed using paired t-tests to assess changes within each group and independent t-tests to compare differences between the two groups. Results: Both groups showed significant increases in buccal bone and soft tissue thickness compared with baseline. At 2 mm below the marginal crest, buccal bone thickness did not differ significantly between the two groups ( Conclusion: Both autogenous dentin and bone grafts effectively enhanced buccal bone and soft tissue thickness around immediate implants. Autogenous bone grafts produced significantly greater increases in buccal bone at 5 mm below the marginal crest.
