[The orthodontic diagnosis].

Orthodontic diagnostics are based on medical history and clinical examination, and involve more than mere classification. Various diagnostic systems help structure the assessment of skeletal, dental, and functional abnormalities. In addition to traditional classifications such as Angle s, aesthetic and 3D aspects are becoming increasingly important. Technological developments, such as artificial intelligence and deep learning, enhance the reliability of measurements and classifications, although challenges with accuracy and transparency persist. While artificial intelligence can accelerate and enrich the diagnostic process, particularly for less experienced practitioners, it is no substitute for clinical assessment. Complex cases require human interpretation and interdisciplinary collaboration. Ultimately, treatment decisions depend on the interaction between patient and practitioner.
