Jaw reconstruction after ablative surgeries poses significant challenges for maxillofacial reconstructive surgeons. Offering maximum functional rehabilitation, osseous free flaps have become the standard of care. The conventional approach involves shaping donor bone segments into the jaw configuration in a free-hand fashion, which can lead to unpredictable and suboptimal outcomes. Recent advancements in computer-assisted surgery, virtual surgical planning (VSP), and 3-dimensional printing technologies offer promising solutions to these challenges, enabling the fabrication of patient-specific surgical guides and patient-specific surgical plates. This article outlines the workflow of VSP and the clinical application of patient-specific devices in jaw reconstruction.
