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 thirty-six (36) months following graduation. This permits three (3) possible February exams. To encourage prompt examination following graduation, the time-limited certificate will expire ten (10) years from the date of the first available Initial Certification Exam.
1. Patient Source
Cases may be presented that have been entirely treated, from appliance placement through appliance removal, by the examinee under direct supervision of a clinical instructor in a 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.
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 demonstrate 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.

FIRST RECERTIFICATION EXAMINATION
This Clinical Examination is given prior to the expiration of the
Diplomate's first time-limited Certificate and no earlier than three (3)
years prior to the expiration date if certified via the Initial
Certification Exam.
This examination will also be utilized for any orthodontist who meets all requirements for the Clinical Examination but did not take the Initial Certification Examination following graduation from an orthodontic graduate program.
