Optimal sites for miniscrew insertion in anterior aesthetic region: a CBCT study for different vertical skeletal patterns.
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
introductionThe objective of this retrospective cohort study was to measure the root distance, bone thickness and bone density in maxillary anterior region with different vertical skeletal patterns based on CBCT data, and provide reference for the optimal site for miniscrew insertion in anterior aesthetic region.
methods60 adult patients(18-29years) with skeletal Class I angle (ANB angle = 2° ± 2°) were selected and divided into three groups (n = 20) according to vertical skeletal patterns.The population was divided into 3 groups according to the measured SN-GoGn angle: hypodivergent (SN-GoGn < 27°), average (27°≤ SN-GoGn ≤ 37°) and hyperdivergent (SN-GoGn > 37°) groups. The CBCT data was processed and measured by Dolphin Imaging and Mimics Medical. Measurement indicators included interradicular distances (IRD), overall bone thickness (OBT), cortical bone thickness (CBT), cortical and cancellous bone density (CoBD & CaBD). One-way ANOVA test of variance was used for statistical comparisons.
resultsIRD increased with apical height, reaching an maximum average measurement of 4.750 ± 1.226 mm at 10 mm axial section. Within the same axial section, the IRD of the region between the two central incisors was significantly larger than that of the other regions. There was no statistical difference in IRD among different vertical skeletal patterns. OBT increased with vertical height in the 2-6 mm axial sections, and no significant difference among three groups. There was a statistical difference of the CBT at 4-8 mm axial sections among the three groups (P < 0.05), but not at 10 mm axial section. There was no statistical difference (P < 0.05) of CaBD among different vertical skeletal patterns. However, there are statistically difference of CoBD in many regions between hypodivergent and hyperdivergent groups.
conclusionsThe anatomical structure in anterior aesthetic region of individuals varies greatly, and interradicular distances is not affected by vertical skeletal pattern. However, in general, hypodivergent patients have higher bone density and greater bone thickness than that of hyperdivergent patients, which means more safe regions to choose for miniscrew insertion.
