Abstract
We owe a great deal of gratitude to pioneer surgeons and orthodontists in the field of orthognathic surgery (OGS).1 Although there have been many giants in both fields, 3 surgeons and 3 orthodontists deserve special mention for their milestone contributions. These surgeons are Hugo Obwegeser, William Bell, and Hans Luhr and the orthodontists are Edward Angle, William Proffit, and Lawrence Andrews. Obwegeser described a safe and practical way to section and reposition the maxilla (i.e., Le Fort I osteotomy), the mandible (i.e., sagittal ramus osteotomies), and the chin (i.e., intraoral oblique osteotomy).
