Crestal Bone Loss and Peri-Implant Conditions at Tissue-Level Implants: Influence of Prosthesis Type After 25 Years.
Observational study in Clinical implant dentistry and related research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo evaluate long-term crestal bone level changes (ΔCBL) and prevalence of peri-implant conditions according to the type of implant-supported fixed dental prosthesis (IFDP), and to identify implant-, prosthetic-, and patient-related factors associated with ΔCBL. MATERIALS AND
methodsThis single-center observational study evaluated patients rehabilitated with single crowns (SCs), splinted crowns (SPs), or bridges (BRs) on tissue-level implants after 10 and 25 years of function. Standardized clinical and radiographic evaluations were performed, and peri-implant conditions were diagnosed according to established consensus definitions.
resultsA total of 147 patients with 233 implants were included. The prevalence of peri-implantitis (PI) increased from 10 to 25 years, from 2.3% to 7.8% for SC, from 1.6% to 6.3% for SP, and from 0% to 4.9% for BR, with no significant differences between IFDP types at either time point (p ≥ 0.95). SP tended to have higher peri-implant mucositis (PM) rates at 25 years (87.3%), compared to SC (74.4%) and BR (80.5%). Mean ΔCBL was -0.37 ± 0.91 mm for SC, -0.25 ± 0.85 mm for SP, and -0.70 ± 1.0 mm for BR, with no significant differences between IFDP types (p = 0.37). Multivariate analyses demonstrated that greater ΔCBL was significantly associated with incisor region location (-0.74 mm), increased probing depth (-0.16 mm per mm), and suppuration on probing (-0.97 mm), all p ≤ 0.05. In contrast, prosthetic retention, marginal misfit, and prosthet emergence geometry were not significantly associated with ΔCBL.
conclusionsOver 25 years, the type of IFDP did not significantly affect ΔCBL or the prevalence of PM and PI around tissue-level implants. Long-term bone stability was primarily influenced by implant location in the incisor region, increased probing depths, and the presence of suppuration.
