Scenario-based Exam Preparation

As part of preparation for the Scenario-based Oral Clinical Examination, the ABO highly recommends that examinees gain as much experience as possible working through patient cases completing an objective analysis of the facts to form their own judgment.  These critical thinking exercises will strengthen an examinee's skills as he or she prepares for the scenario-based examination.  This process also promotes the opportunity for self-evaluation and reflection on case outcomes.


Tools previously created by the ABO to assess case outcomes will be utilized within the scenario-based examination process.  These tools include the Cast-Radiograph Evaluation (CRE), Case Management Form (CMF), and cephalometric superimposition technique and interpretation.


  1. Examinees should be fluent in the Cast Radiograph Evaluation (CRE) measurement technique
  2. The Case Management Form (CMF) treatment objectives should be thought of in three planes of space
  3. Set objectives should be determined by what is best for the patient, not by what the patient/family wants to hear
  4. Examinees should be able to determine correct landmark placement for cephalograph
  5. Examinees should be able to identify appropriate regional anatomy for cranial base, maxillary, and mandibular superimpositions
  6. Examinees should be able to interpret superimpositions and differentiate changes due to growth vs. treatment mechanics
  7. Examinees should be able to detect tracing and superimposition errors
