Patient-Specific vs. Conventional Positioning in Sagittal Split Ramus Osteotomy

A patient-specific surgical guide designed using STL-based digital planning in Blender and produced via 3D printing with biocompatible surgical resin (Formlabs SLA printer). Used to guide and stabilize the proximal mandibular segment during sagittal split ramus osteotomy.

The proximal mandibular segment is positioned manually by the surgeon based on visual and tactile feedback without the use of a positioning guide. This technique represents the standard method in sagittal split ramus osteotomy.
