This book provides a practical, easy-to-follow approach to the diagnosis and treatment of the most common orthognathic and orthodontic problems encountered in clinical practice. Procedures such as the clinical evaluation of a patient, analysis of diagnostic records, treatment planning, and surgical methods with possible complications are discussed, and clinical cases are presented to demonstrate treatment outcomes. The development of a visual treatment objective for each deformity or combination of deformities and the three most common surgical techniques, the Le Fort I maxillary osteotomy (including segmental surgery), the bilateral sagittal split ramus osteotomy of the mandible, and the sliding genioplasty, are comprehensively described and clearly illustrated in a step-by-step manner, with an emphasis on the basic principles necessary for a successful result. An excellent guide for residents and beginning surgeons and a helpful resource for experienced surgeons.
