Iran Dental Board - Prosthodontics study plan

Compare chamfer, shoulder, shoulder-with-bevel, and knife-edge finish lines, and state the axial and occlusal reduction in millimetres required for full-metal, metal-ceramic, and all-ceramic single units.

Sequence the preparation of a vital molar for a metal-ceramic crown and of two abutments for a three-unit fixed partial denture, naming the criteria for retention form, resistance form, and path of withdrawal at each step.

Select an impression protocol (single-arch versus dual-arch, retraction cord versus paste, wash versus monophase) for subgingival and supragingival margins and list the criteria for an acceptable record.

Justify provisional restoration design for a patient with a short clinical crown or a parafunctional habit, including material choice and occlusal adjustment.

Outline the parameters of an acceptable cast (marginal fit, internal fit, contact tightness, occlusion) and the sequence for intraoral adjustment and cementation.

Differentiate feldspathic porcelain, lithium disilicate, glass-infiltrated ceramic, and the 3Y and 5Y zirconia generations by flexural strength, minimum thickness, and whether they require adhesive or conventional cementation.

Match luting agents (zinc phosphate, resin-modified glass ionomer, self-adhesive resin, conventional resin) to each restoration type and specify the intaglio surface treatment and tooth conditioning for each.

Explain connector cross-sectional design and pontic design (hygienic, modified ridge lap, ovate, conical) and select the appropriate design for anterior and posterior edentulous spans, including cantilever limits.

Diagnose the causes of ceramic chipping, framework fracture, marginal discoloration, and decementation, and rank the corrective options by evidence strength.

Relate the properties of casting alloys, base-metal alternatives, and CAD/CAM blocks to indications and to laboratory fabrication errors.

Reproduce the complete-denture workflow from primary impression through border moulding, master cast, record bases, jaw relation records, try-in, and insertion, and state the objective acceptance criterion at each appointment.

Justify the choice of occlusal scheme (bilaterally balanced, lingualized, monoplane) and tooth mould for a patient with a severely resorbed mandibular ridge or a class II jaw relationship.

Determine vertical dimension of occlusion and centric relation record with two independent methods and identify the signs of an incorrect record.

Diagnose and correct the common post-insertion complaints of looseness, sore spots, phonetic disturbance, and retching, and distinguish them from errors in the impression or the record.

Compare heat-polymerized, injection-moulded, and pour resins and the choice of acrylic versus composite teeth for dimensional accuracy, wear, and repair.

Classify six patient scenarios using Kennedy classification with Applegate's rules and design the framework, specifying rests, rest seats, clasp assembly components, major connector, and minor connectors for each.

Compare the bounded saddle with the free-end saddle and justify the choice among a fixed partial denture, a removable partial denture, and an implant-supported option.

Plan the survey, path of insertion, and guiding planes for a class III modification case and identify the design features that prevent torque, lever action, and framework rotation.

Manage the combination case in which a removable partial denture opposes a complete denture or is used with a rotational path or altered-cast technique, and sequence the clinical and laboratory steps.

Diagnose framework misfit and the design errors that cause tissue irritation, then state the adjustment sequence before relining is considered.

Relate implant number, distribution, and angulation to the prosthesis type (single crown, splinted crowns, overdenture with stud or bar attachment, screw-retained hybrid) and justify each selection.

Compare screw-retained with cement-retained designs on retrievability, aesthetics, cleansability, and the risk of peri-implant disease, and state when each is contraindicated.

Select the impression technique (open tray, closed tray, splinted, digital scan with scan bodies) and the abutment type for a given case, and design the emergence profile with the surrounding soft tissue in mind.

Distinguish peri-implant mucositis from peri-implantitis and identify the prosthetic contributors of misfit, cantilever load, non-passive fit, and unfavourable occlusal scheme.

Plan an edentulous arch rehabilitation, verifying passive fit and specifying the occlusal scheme and the maintenance recall interval.

Determine centric relation, maximum intercuspation, and vertical dimension of occlusion, and explain how each record is made and how each can be verified clinically.

Compare mutually protected occlusion, group function, and bilaterally balanced occlusion, and select the appropriate scheme for a natural dentition, a fixed reconstruction, and a complete denture.

Interpret semi-adjustable articulator settings and facebow records and decide when a semi-adjustable or fully adjustable instrument is justified over a simple hinge or average-value setting.

Apply the standard Axis I screening categories to ten case vignettes and distinguish temporomandibular disorder pain from odontogenic, neuropathic, and myogenous pain.

Sequence the management of a patient with temporomandibular disorder who also needs prosthetic reconstruction, including splint therapy, occlusal adjustment, and the point at which reconstruction may begin.

Apply the smile design parameters of tooth proportion, midline, incisal edge position, gingival zenith, and buccal corridor, and relate shade selection and colour science to the choice of ceramic and cement.

Describe the digital workflow from intraoral scan through CAD design to milling or printing, and state the clinical limitations of scanners, of minimimum thickness rules, and of bonding to digitally fabricated restorations.

Compare laminate veneers with full-coverage crowns on indication, enamel preservation, and bonding requirement, and outline a minimally invasive preparation.

Plan an obturator, a facial prosthesis, or a speech aid, including the timing relative to surgery, retention method, and the impact of the defect on the impression technique.

Modify treatment planning for older adults by accounting for xerostomia, polypharmacy, cognitive impairment, reduced dexterity, root caries, and the goal of preserving function over aesthetics.

Complete at least two full-length mock examinations under timed conditions and record the percentage score per domain.

Analyse every incorrect answer by cause (knowledge gap, misread stem, calculation, or recognition failure), and convert each knowledge gap into a flashcard or a one-line summary.

Rehearse high-yield recall items: minimum thicknesses, connector dimensions, reduction amounts, clasps and rests, Kennedy and Applegate rules, and peri-implant diagnostic thresholds.

Re-attempt the weakest 60 questions from weeks 1 to 7 and confirm the score rises above the target threshold.
