Chew and Renew: Comparative Evaluation of a Novel Fixed Functional and Nonfunctional Space Maintainer.
Article in International journal of clinical pediatric 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: Premature loss of primary molars often leads to malocclusion, space loss, and functional disturbances. While conventional fixed space maintainers like band and loop (BL) preserve arch space, they fail to restore function. The double band and pontic (DBP) design introduces a functional component aimed at improving masticatory efficiency and parental satisfaction. Aim: To compare and correlate the clinical and radiographic success of fixed functional (DBP) and nonfunctional (BL) space maintainers over 3, 6, and 12 months. Materials and methods: A split-mouth, double-blinded randomized controlled trial was conducted in 30 children aged 7-9 years requiring bilateral extraction of mandibular primary second molars. One side received BL, and the other DBP. Parameters assessed included gingival health (Löe and Silness index), survival rate, space loss (study models), chewing efficiency (peanut crunch test), parental acceptance (Likert scale), and eruption interference (radiographs). Data were analyzed using SPSS v 20.0. Results: DBP demonstrated significantly better chewing efficiency, higher parental acceptance, and superior space maintenance with reduced appliance failures compared to BL. However, DBP was associated with slightly increased gingival inflammation and minor eruption interference in 13.8% of cases at 6 and 12 months. Discussion: The DBP appliance provides functional and esthetic benefits while effectively maintaining space. Though slightly more plaque retentive, its advantages in stability and mastication justify its clinical use. It marks a shift toward multifunctional space maintenance in pediatric dentistry. Conclusion: The DBP appliance emerges as a promising, functionally superior alternative to conventional BL, combining esthetics, chewing efficiency, and durability in pediatric space maintenance.
