Training in anterior and posterior zirconia cantilevered resin-bonded fixed dental prostheses: design and educational outcomes.
Article in BMC medical education, 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
backgroundResin-bonded fixed dental prostheses, particularly zirconia-based single-retainer cantilever designs, offer a minimally invasive option for the replacement of anterior and, more recently, posterior teeth. This study aimed to develop a cost-effective reusable simulator and evaluate a one-day, simulation-based continuing education program grounded in current evidence for anterior cantilever (AC) and posterior cantilever (PC) zirconia resin-bonded fixed dental prostheses (RBFDPs).
methodsTwenty-six volunteer general dental practitioners attended two sessions that blended lectures with two hands-on exercises using custom 3D printed modified typodonts. Self-perceived knowledge, confidence, and satisfaction were captured before, immediately after, and four months postcourse with questionnaires based on the Likert scale. Descriptive statistics (means and standard deviations) were calculated, and repeated items were analysed using non-parametric Kruskal–Wallis tests (R software, version 4.5.1).
resultsThe baseline responses indicated modest experience with AC-RBFDPs (mean 3.54 ± 1.84) and PC-RBFDPs (2.27 ± 1.76) but high demand for theoretical training. Immediate satisfaction reached a very high level (overall 5.00 ± 0.00), and all individual items evaluating the education program exceeded 4.5. At four months, satisfaction remained high (4.63 ± 0.50), and confidence in zirconia bonding improved significantly (3.04 ± 1.04 to 4.00 ± 0.89; p < 0.05), although reported implementations of AC-RBFDPs (3.06 ± 1.18) and PC-RBFDPs (3.00 ± 1.26) in clinical practice remained limited.
conclusionsA single-day, simulation-based course using an affordable, recyclable simulator markedly enhanced perceived competence and maintained high satisfaction at four months, while it translated only partially into practice change among general dentists. Given the small sample size and the exclusive use of self-reported outcomes, these findings should be generalised with caution. Future work should rely on larger, longitudinal multimodal strategies and include objective performance and patient-centred outcomes. CLINICAL TRIAL NUMBER: Not applicable.
