Comparison of accuracy of maxilla between virtual surgical planning and conventional surgical planning in bimaxillary orthognathic surgery: a randomized controlled trial.

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
backgroundVirtual surgical planning (VSP) improves accuracy in orthognathic surgery, but its differences from conventional surgical planning (CSP) remain unclear. This study compares VSP and CSP accuracy in maxillary repositioning.
methodsA randomized controlled trial of 20 patients undergoing bimaxillary surgery was conducted. Patients were assigned to VSP (3D planning, 3D-printed splints) or CSP (cast model surgery, conventional splints). Pre- and postoperative Computed Tomography (CT) scans were superimposed using voxel-based registration, measuring anteroposterior (Y), mediolateral (X), and vertical (Z) positional changes of A point, ANS, U1, U3, U6 landmarks.
resultsNo significant differences in planned and actual surgical outcomes (p > 0.05). 2D planning (P2D) and 3D planning (P3D) showed significant differences in key maxillary landmarks, indicating that 3D planning provides additional refinements in skeletal positioning. However, VSP showed larger absolute discrepancies in U1L, U1R, U3L, U6L (p < 0.05), particularly in the anteroposterior (Y-axis) direction. Splint thickness and condylar simulation methods could also affect accuracy.
conclusionsVSP and CSP provide comparable accuracy; however, VSP shows greater anterior-posterior discrepancies. Further studies should examine splint design and condylar modeling to optimize surgical precision.
