Iran Dental Specialty Board - Orthodontics study plan

Reconstruct cephalometric and implant-based growth data for the cranial base, maxilla, and mandible from age 4 to 20, writing a one-page summary of each structure's velocity curve

Explain the functional matrix concept and identify which craniofacial structures are most responsive to orthopedic force at each developmental stage

Derive the moment-to-force ratio thresholds that distinguish tipping, controlled tipping, translation, and root torque, and state the clinical appliance setup that produces each

Calculate the force system for a simple two-tooth intrusion and a two-tooth retraction, showing the moment balance and the expected center of resistance location for each tooth type

Solve 15 numeric problems on force magnitude, moment, and anchorage loss, documenting the working equation for each

Compare nickel-titanium, stainless steel, beta-titanium, and cobalt-chromium archwires on stiffness, springback, and formability, and match each to a clinical indication

Describe the composition, polymerization mechanism, and bond-failure modes of self-etch, total-etch, and light-cured orthodontic adhesives

Explain friction and binding in sliding mechanics and list three design or material choices that reduce them

Identify the properties of elastomeric chains and modules that determine force decay over four weeks, and state a clinical replacement interval

Interpret a load-deflection curve for three archwire alloys and predict which wire would be selected for initial alignment versus space closure

Perform a complete problem list and prioritized treatment plan for five paper cases using the five-component diagnostic framework (problem list, goals, plan, mechanotherapy, retention)

Trace and identify at least 20 cephalometric landmarks and construct a lateral analysis, reporting SNA, SNB, ANB, Wits, FMA, IMPA, and soft-tissue values

Compare Ricketts, Steiner, and McNamara analyses and state which skeletal relationships each is best suited to detect

Explain the indications, radiation dose, and interpretation of CBCT, panoramic, and occlusal radiographs in orthodontic diagnosis

Evaluate the reliability limits of cephalometric tracing and describe how landmark error propagates into angular and linear measurements

Design a staged archwire sequence for a nonextraction case, specifying wire size, alloy, and activation at each stage and justifying each transition

Compare bracket prescription systems (Roth, MBT, Andrews) on tip, torque, and in-out values and predict the finishing differences between them

Describe the biomechanics and clinical protocol for rapid maxillary expansion, including activation rate, expected sutural response, and signs of failure

Evaluate the evidence for early treatment of Class II and Class III malocclusion and state which interceptive interventions have the strongest support

Assess space maintenance, serial extraction, and habit-control decisions for the mixed dentition using arch-length and timing criteria

Identify the presurgical orthodontic objectives and the decompensation movements required before a Le Fort I, bilateral sagittal split, or segmental osteotomy

Explain the hierarchy of stability after mandibular advancement, maxillary impaction, and maxillary expansion, and name the relapse risk factors for each

Describe the clinical and imaging assessment of temporomandibular disorders, distinguishing myogenous, arthrogenous, and disc-displacement presentations

Evaluate the evidence on orthodontic treatment as a cause or cure of temporomandibular disorders and state the current consensus clearly

Compare centric relation and maximum intercuspation and explain how occlusal interference is assessed in a symptomatic patient

Compare fixed, removable, and bonded retention protocols on outcome, cost, and failure rate, and select a retention regimen for three distinct case types

Explain the biology of relapse, including periodontal fiber reorientation, PDL memory, and late mandibular growth, and relate each to retention duration

Assess periodontal risk in an adult orthodontic patient using bone level, attachment loss, biotype, and plaque control, and modify the treatment plan accordingly

Describe the interdisciplinary sequencing of orthodontics with implant placement, crown lengthening, and restorative space management

Identify the orthodontic forces and tooth movements that risk root resorption, dehiscence, and gingival recession, and state the monitoring interval

Formulate a focused clinical question in PICO format for three orthodontic dilemmas and map each to an appropriate study design

Calculate and interpret sensitivity, specificity, positive predictive value, number needed to treat, and confidence intervals from a published orthodontic study

Appraise a randomized controlled trial and a systematic review using risk-of-bias and GRADE criteria, and state the certainty of the evidence

Apply the principles of informed consent, competence, and conflict-of-interest disclosure to three orthodontic practice scenarios

Distinguish statistical from clinical significance in a sample of orthodontic abstracts and identify spin in the conclusions

Synthesize the highest-yield facts from the heaviest domains into a condensed review sheet of no more than four pages

Complete a timed 120-question mock examination and score at or above 70 percent overall and at or above 60 percent in every domain

Review every missed mock question and write the underlying principle, not just the correct answer, for each

Re-derive the biomechanics equations and cephalometric norms from memory without reference material

Build a final-week revision schedule that allocates remaining time in proportion to mock-exam domain deficits
