Exam overview and details

The American Board of Orthodontics (ABO) Board Certification represents the pinnacle of professional achievement in the specialty of orthodontics and dentofacial orthopedics. This voluntary, peer-evaluated process signifies a practitioner's commitment to lifelong learning, clinical excellence, and the highest standards of patient care. Certification is granted upon successful completion of a rigorous examination that assesses a candidate's diagnostic acumen, treatment planning expertise, and clinical case execution against nationally recognized standards. Unlike a state license to practice, ABO Certification is a testament to a specialist's dedication to exceeding minimum requirements and achieving mastery within the field. It is a distinction earned through a comprehensive evaluation of actual treated cases, written examinations, and oral defense of clinical decisions. Holding this certification positions an orthodontist as a leader committed to evidence-based practice and continuous quality improvement, enhancing both professional credibility and patient trust.
