About this exam

The Iranian specialty board in orthodontics (بورد تخصصی ارتودنسی) is the national credential that a dentist holding a specialty degree in orthodontics must obtain to be recognized as a board-certified orthodontist in Iran. It is aimed at graduates of accredited Iranian orthodontic residency programs who are completing their specialty training and preparing to practice, teach, or take hospital and academic posts. The examination is set and administered by the official Iranian specialty board body; this page is an independent study resource and is not affiliated with, endorsed by, or connected to that body or any university. The assessment spans the full orthodontic curriculum: craniofacial growth and development, diagnosis and treatment planning, cephalometrics and imaging, biomechanics and tooth movement, materials and appliances, fixed and removable therapy, early and interceptive treatment, orthognathic surgery and dentofacial orthopedics, retention, interdisciplinary care with periodontics and restorative dentistry, temporomandibular disorders and occlusion, and evidence-based practice, research methods, and professional ethics. Preparation should combine a structured review of these domains with supervised clinical experience, cephalometric tracing practice, and rehearsal of case-based and oral defense formats. Because exam logistics change, confirm current dates, structure, and any published figures directly with the official board.

What you'll study

Common questions

About Iran Dental Specialty Board - Orthodontics preparation

Who is eligible to sit the orthodontic specialty board?

Candidates are normally dentists who have completed an accredited Iranian orthodontic residency and hold the relevant specialty qualification. Eligibility rules, required documents, and deadlines are set by the official board body, so verify the current requirements on its website before applying, since they can change between cycles.

What is the exam format?

Expect a combination of multiple-choice items, written and case-based questions, and an oral examination in which you defend diagnoses and treatment plans. The precise mix and weighting are published by the official body. Prepare for all formats rather than assuming one dominates, because case discussion is usually where clinical reasoning is tested.

How long is the exam and how many questions are there?

The official body publishes the current question count, timing, and session structure for each cycle, and these are not fixed permanently. Check its official announcements rather than relying on what earlier candidates report, because formats have changed between years. Plan your practice timing around the published structure once it is released.

How difficult is the exam?

It is a specialty-level assessment, so it assumes working command of the whole curriculum rather than isolated facts. The hardest part for most candidates is not recall but applying biomechanics and cephalometric reasoning to unfamiliar cases under time pressure. Candidates who have treated a broad case mix during residency generally find the clinical sections more manageable.

What happens if I fail - can I retake it?

Retake rules, waiting periods, and any limits on attempts are determined by the official board body and are not standardized. Consult its regulations for the current policy. If a retake is permitted, request feedback on your weak domains if available, and rebuild your study plan around those areas rather than repeating the same broad review.

In what order should I study the domains?

Start with growth and cephalometrics, because diagnosis and treatment planning depend on them. Then move to biomechanics and materials, which underpin appliance selection. Follow with appliance therapy, early treatment, and surgical orthodontics, and finish with retention, interdisciplinary care, TMD, and evidence-based practice. Integrate case practice throughout rather than leaving it to the end.

What are the most common failure modes?

Candidates often lose marks by reciting classifications without linking them to a treatment decision, misreading cephalometric values, or defending a plan they cannot justify biomechanically. In oral examinations, vague answers and unwillingness to state assumptions hurt. Practice explaining the force system behind each mechanotherapy choice and the alternatives you rejected.

How should I prepare for the oral and case-based sections?

Work through complete records - models, photographs, radiographs, cephalometric tracings - and present each case aloud as if to an examiner: problem list, aims, mechanics, anchorage, retention, and risks. Time yourself and invite a supervisor to challenge your plan. This builds the structured reasoning and composure that oral examiners assess.

Does board certification expire or require renewal?

Validity periods and any continuing education or recertification requirements are set by the official body and may change. Confirm the current rules directly with it. Do not assume certification is permanent, and keep records of any continuing education you complete in case documentation is requested at renewal.

Is this page officially connected to the Iranian board?

No. This is independent study material written to help candidates prepare. It is not affiliated with, endorsed by, or authorized by the Iranian specialty board body or any dental school. Always treat official announcements as authoritative for eligibility, format, scheduling, fees, and results.
