Digital quantitative analysis of biomechanical factors of proximal contact loss of first molar implant crown.
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
backgroundThe anterior component of force (ACF) is key to proximal contact loss (PCL) after implant restoration, yet its quantitative impact remains unclear. This study employed digital model analysis to indirectly assess the effects of ACF and examine its association with PCL.
methodsFollowing final restoration, 3D surface and buccal occlusal data were obtained from ninety first molar implant sites and mesial adjacent teeth. Occlusal force-induced changes in proximal contact gap (Δd
resultsThe 6-month PCL incidence was 17.78%, and Δd
conclusionThis study achieved an indirect assessment and quantification of the effect of ACF through digital model analysis technology, and clarified its correlation with the PCL of the implant, providing new evidence and methodological references for related biomechanical research.
