Time-dependent adaptation and clinical efficacy of complete dentures: evidence from a Bayesian mixed-effects model.
Article in BMC oral health, 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
backgroundTo investigate the clinical efficacy of Biofunctional Prosthetic System (BPS) complete dentures during the early adaptation period, with a focus on functional outcomes and patient-reported quality of life as assessed by the Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT).
methodsA single-arm prospective cohort study evaluated masticatory efficiency (ME), occlusal function (occlusal contact area [OCA], asymmetry index of occlusal force [AOF]), and OHIP-EDENT at baseline, 1 week, 1 month, and 3 months post-insertion. A Bayesian mixed-effects model was employed to analyze repeated measures, providing robust probabilistic inference on temporal trajectories and influencing factors.
resultsData from 18 patients were analyzed. Denture-wearing time was the principal determinant of outcomes. OHIP-EDENT scores improved within the first week, while ME and OCA showed progressive consolidation by 1 and 3 months, revealing a staged adaptation process. No consistent associations were observed for age, sex, or prior denture experience within the early observation period.
conclusionsTime emerged as the main determinant of early BPS denture adaptation. The findings delineate a sequential adaptation pattern in which early psychosocial benefits, as measured by OHIP-EDENT, precede functional recovery. These results underscore the importance of structured clinical follow-ups at 1 week, 1 month, and 3 months, and demonstrate the methodological value of Bayesian mixed-effects models in enhancing inference in prosthodontic research and generating clinically relevant guidance for patient management.
