Types of Clinical Examinations
Note: No case may be presented to the Board more than one time
INITIAL CERTIFICATION EXAMINATION

This Clinical Examination is offered to orthodontists following completion of
their orthodontic education. The orthodontist must be a graduate of a CODA
(Commission on Dental Accreditation) accredited orthodontic program and have
successfully passed the ABO Written Exam. The examinee must present for this
examination within twenty-four (24) months following graduation. The
time-limited certificate will expire ten (10) years from the completion of the Initial Certification Exam.
1. Patient Source
Of the six cases required, a minimum of three cases must be presented that have been entirely treated, from appliance placement through appliance removal, by the examinee under direct supervision of a clinical instructor in an ADA accredited orthodontic program. Active treatment ends when the same resident removes the appliances and places the patient in retention. In cases of multi-phased treatment, the final phase of full treatment (appliance placement to appliance removal) administered by a single resident is acceptable. A Confirmation of Resident Treated Cases (pdf) from the Program Director and/or Chairperson is required to assure that the cases presented meet these requirements.
The balance of case requirements will be collected, either from residency within 24 months of graduation or from post-residency practice, within ten (10) years and two (2) more attempts at completion of requirements.
2. Components of the Initial Certification Exam
- Board Case Oral Examination (BCOE)
- Case Report Examination (CRE)
- Case Report Oral Examination (CROE)
3. Case Criteria for the Initial Certification Exam
The Case Report Examination component requires six (6) Case Reports
consisting of
- three (3) cases with a DI of twenty (20) or greater,
- three (3) cases with a DI of ten (10) or greater.
The six case presentation must contain:
- at least one (1) non-surgical case treated with four (4) quadrant extractions that demonstrates effective space closure (identified as "Extraction Case").
- at least one (1) non-surgical case with bilateral end-to-end or greater Class II molar relationship
present at the time of appliance placement. A unilateral full-step Class II molar relationship is also acceptable. The final treatment result should exhibit a Class I molar and canine relationship (identified as "Class II Case").
- no more than one (1) case treated with orthognathic surgery (identified as "Surgical Case"). Note that a surgical case is not required. Any surgical case needs interim (pre-surgical) records.
4. Banking Process
- Of the six cases required, a minimum of three cases must be presented via personal appearance at the clinical examination.
- Of the cases that are presented from residency, cases which are Complete will be “banked”, or documented, at the ABO central office. The examinee must collect the balance of required cases, either from residency within 24 months of graduation or from post-residency practice, for grading within ten (10) years and two (2) more attempts.
- If at least three (3) cases are Complete and include at least one (1) case with a DI of 20 or above, and the BCOE is Complete, the examinee may mail the remaining cases to the ABO for grading at a future clinical examination.
- The examinee must return to a future clinical examination to complete the ICE requirements IF:
- less than three (3) cases are Complete
- three (3) cases are Complete, but do not include one (1) case with a DI of 20 or above
- the BCOE is Incomplete
- If no cases from residency are Complete, the examinee will submit a new registration and take the Beginning Certification Examination.
