Comparative analysis of nerve fibers, PIEZO family and bone structural parameters difference surrounding dental implants.
Article in BMC oral health, 2025. 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
backgroundNerve fibers embedded within bone tissue play a pivotal role in regulating osseous homeostasis. Emerging evidence indicates the presence of neural networks surrounding dental implants. The functional integrity of these nerve fibers is maintained through various ion channels, particularly those belonging to the PIEZO family. This study aims to: (1) characterize the spatial distribution patterns of nerve fibers and PIEZO family around dental implants, and (2) investigate their potential correlations with bone microarchitecture surrounding dental implants.
methodsMale rat models with right maxillary first molar dental implants were established. Following a 4-week osseointegration period, spatial variations in nerve fiber density and PIEZO family expression were quantitatively assessed across 8 anatomically defined buccolingual regions. Complementary Micro-CT analyses were performed to evaluate three-dimensional bone microarchitecture surrounding dental implants.
resultsThe study revealed regional heterogeneity in nerve fiber density across the 4 anatomical zones. Nerve fiber density showed no significant difference between peri-implant and adjacent tissues. While PIEZO-positive fibers generally mirrored overall nerve fiber distribution, the apical region exhibited a significantly higher proportion of PIEZO2-positive fibers in peri-implant bone versus adjacent bone.
conclusionsPeri-implant regions exhibited higher nerve fiber density and enhanced bone microarchitecture, suggesting neurogenic modulation of osseointegration dynamics. Mechanistically, the PIEZO family may mediate this neuro-osseous crosstalk during bone remodeling around implants. These findings offer novel perspectives on the mechanistic basis of peri-implant bone adaptation.
