Splintless approach improves surgical accuracy in Le Fort I osteotomies: a systematic review and meta-analysis.

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: Accurate bone repositioning is crucial during orthognathic surgery (OS), as even slight deviations from the planned position can impact function and esthetics. As splintless techniques are rapidly evolving, patient-specific implants (PSI) and digital surgical templates (DST) are establishing new standards. This systematic review and meta-analysis aimed to assess the effectiveness of splintless OS compared to virtually planned splints. Materials and methods: We conducted our study in accordance with the guidelines of the PRISMA 2020 framework. A systematic search was performed on November 15, 2024, across PubMed, Embase, and Cochrane. We included randomized controlled clinical trials and observational studies. The primary outcome was surgical accuracy, assessed by the mean linear and angular deviation across the three spatial axes. Results: Among the 8,563 identified studies, sixteen met inclusion criteria, and nine were subsequently pooled for meta-analysis. Findings were statistically significant for splintless OS concerning linear deviation along the anteroposterior (MD = -0.49 mm; 95% CI: [-0.73, -0.26]), vertical (MD = -0.32; 95% CI: [-0.53, -0.11]), and mediolateral (MD = -0.37; 95% CI: [-0.59, -0.15]) axes. In terms of angular deviation, PSI showed significant results with reduced discrepancies around the anteroposterior axis (roll) (MD = -0.48; 95% CI: [-0.88, -0.08]). The results did not achieve statistical significance in yaw (MD = -0.71; 95% CI: [-1.50; 0.09]) or pitch (MD = -0.57; 95% CI: [-1.45; 0.31]). However, surgical accuracy has shown consistent improvement across studies. Conclusion: Splintless OS consistently showed significantly lower mean deviations from the planned position, outperforming splint-based OS. These results indicate that PSI and DST may offer superior surgical accuracy compared to virtually planned splints. DST may be a valuable, potentially lower-cost alternative, providing the same clinical benefits as PSI. Systematic Review Registration: https://www.crd.york.ac.uk/PROSPERO/view/CRD42024605292.
