Edward H. Angle is regarded as the father of modern orthodontics because he developed the first comprehensive classification system of malocclusions, which remains the foundation for diagnosis and treatment planning today. He also designed specialized orthodontic appliances and introduced standardized techniques, greatly advancing the field’s scientific and clinical practice. His contributions established orthodontics as a distinct dental specialty focused on correcting dental and skeletal malalignments to improve function and aesthetics. Angle’s systematic approach and innovations set the standards for modern orthodontic treatment protocols.
