Patient-specific guides and osteosynthesis versus CAD/CAM occlusal splints in orthognathic surgery: a systematic review and meta-analysis of accuracy, operative time, and complications.
BACKGROUND Orthognathic surgery increasingly relies on digital transfer workflows, most commonly CAD/CAM occlusal splints or patient-specific implants (PSI). However, prior meta-analyses were limited by methodological heterogeneity, sparse randomized evidence, and insufficient axis-specific analyses, leaving the magnit...
