The mandible, as a critical structure in facial form and function, plays an essential role in mastication, speech, and aesthetics. Its reconstruction presents a unique set of challenges to surgeons, requiring a delicate balance between technical precision, aesthetic considerations, and functional restoration. This book is dedicated to addressing these challenges, offering a comprehensive exploration of mandibular reconstruction techniques and advancements. The inspiration for this work stems from years of clinical practice and collaboration with experts across multiple disciplines. Mandibular defects can arise from trauma, tumour resections, congenital anomalies, or infections. Each scenario requires an individualized approach, tailored to the patient's specific needs, and involves a blend of traditional surgical principles and innovative technologies, including virtual surgical planning, 3D printing, and modern prosthetics. This book seeks to bridge the gap between foundational knowledge and cutting-edge practice. It is designed to be a practical resource for surgeons, trainees, and healthcare professionals, detailing step-by-step procedures.
