1According to the Atwood classification of edentulous alveolar ridges, which class is characterized by a high, well-rounded ridge?

A.Class I (Dentate)

B.Class II (Post-extraction)

C.Class III (High, well-rounded)

D.Class IV (Knife-edge)

Explanation: Class III of the Atwood classification represents a high, well-rounded alveolar ridge. This type of ridge provides excellent stability and support for a complete denture because of its broad surface area and resistance to lateral forces. In contrast, other classes represent different stages of resorption or dentition status.

2A denturist measures a patient's vertical dimension of rest (VDR) as 72 mm and the vertical dimension of occlusion (VDO) as 66 mm. What is the calculated freeway space for this patient?

A.2 mm

B.4 mm

C.6 mm

D.8 mm

Explanation: Freeway space (interocclusal distance) is calculated by subtracting the vertical dimension of occlusion (VDO) from the vertical dimension of rest (VDR). In this case, 72 mm - 66 mm = 6 mm. A freeway space of 6 mm indicates that the VDO is under-closed, which can lead to reduced chewing efficiency and an aged facial appearance.

3Which of the following clinical findings is most likely to be observed in a complete denture patient diagnosed with Sjögren's syndrome?

A.Increased physical retention due to thicker saliva

B.Severe mucosal irritation and lack of physical denture retention

C.Rapid alveolar bone resorption in the anterior mandible

D.Hypertrophy of the masticatory muscles

Explanation: Sjögren's syndrome is an autoimmune disorder that attacks moisture-producing glands, leading to severe dry mouth (xerostomia). Saliva is essential for complete denture retention because it creates a thin adhesive film between the denture base and the oral mucosa. Without adequate saliva, patients experience a lack of physical retention and are highly susceptible to friction-induced mucosal irritation, ulcerations, and candidiasis.

4A patient presents with bilateral edentulous areas located posterior to the remaining natural teeth. Which Kennedy Classification of partially edentulous arches does this represent?

A.Class I

B.Class II

C.Class III

D.Class IV

Explanation: Kennedy Class I is defined as bilateral edentulous areas located posterior to the remaining natural teeth. This is the most common partially edentulous configuration and is tissue-supported at the distal ends. Designing an RPD for this class requires careful consideration of indirect retention to prevent rotation under loads.

5According to Applegate's rules for applying the Kennedy Classification, how should the most posterior edentulous area be treated in determining the classification?

A.It is ignored if it is bounded by natural teeth

B.It always determines the primary classification

C.It is classified as a modification space

D.It is only considered if it crosses the midline

Explanation: Applegate's Rule 5 states that the most posterior edentulous area (or areas) always determines the primary classification. Any additional edentulous areas in the same arch are referred to as modification spaces, regardless of their position. This rule ensures consistency in partial denture design planning.

6When fabricating a custom impression tray for a secondary impression using polysulfide material, what is the recommended thickness of the wax spacer?

A.0.5 mm

B.2.0 to 3.0 mm

C.5.0 to 6.0 mm

D.No spacer is required

Explanation: Polysulfide impression material requires a uniform thickness of 2.0 to 3.0 mm to achieve optimum accuracy and minimize polymerization shrinkage. If the material is too thick, shrinkage increases, leading to an inaccurate model; if it is too thin, it may tear upon removal. The wax spacer is placed on the primary cast before tray fabrication and is removed after border molding is complete.

7Which of the following clinical scenarios represents an absolute contraindication for using Zinc Oxide Eugenol (ZOE) as the secondary impression material?

A.A patient with deep tissue undercuts in the tuberosity region

B.A patient with a flat, resorbed mandibular ridge

C.A patient with normal salivary flow

D.A patient requiring a selective-pressure impression technique

Explanation: Zinc Oxide Eugenol (ZOE) is a rigid, non-elastic impression material after it sets. Therefore, it is strictly contraindicated in patients with deep bony or soft tissue undercuts (such as in the maxillary tuberosities or retromylohyoid space) because the set material cannot flex to bypass the undercut, causing either severe trauma to the patient's tissues upon removal, or fracture of the impression itself.

8What is the primary clinical etiology of epulis fissuratum in a long-term denture wearer?

A.An allergic reaction to the acrylic monomer

B.Chronic irritation from an over-extended or ill-fitting denture border

C.Systemic vitamin C deficiency

D.Infection by Streptococcus mutans

Explanation: Epulis fissuratum (inflammatory fibrous hyperplasia) is caused by chronic low-grade irritation from an over-extended or sharp denture border. The tissue responds to this chronic trauma by producing redundant folds of fibrous connective tissue that grow around the offending denture flange. Treatment involves relieving the denture border, using tissue conditioner, or surgically excising the tissue.

9A patient presents with inflammatory papillary hyperplasia of the hard palate. What is the initial conservative management step that the denturist should recommend?

A.Immediate surgical excision of the lesions

B.Prescribing systemic corticosteroids

C.Denture adjustments, improved oral hygiene, and leaving the denture out at night

D.Applying a hard reline to the existing maxillary denture

Explanation: The initial management of inflammatory papillary hyperplasia is conservative, focusing on plaque control, professional cleaning of the denture, tissue conditioning, and instructing the patient to leave the denture out of the mouth for at least 8 hours a day (typically overnight). This allows the inflamed mucosa to recover. Surgical excision is reserved for severe, fibrous cases.

10During a Gothic arch tracing procedure, the apex of the arrow-point tracing represents which of the following mandibular positions?

A.Maximum intercuspation (centric occlusion)

B.Centric relation

C.Most protruded position

D.Postural rest position

Explanation: The apex of a Gothic arch (arrow-point) tracing represents the centric relation of the mandible. Centric relation is the most posterior, superior, and midmost position of the condyles in the glenoid fossae. When the patient performs lateral and protrusive movements, the stylus traces a path on the recording table; the point where these movements meet (the apex) corresponds to the condyles in their terminal hinge position.

Frequently Asked Questions

What is the format of the CDMRE MCQ Examination?

The MCQ component is a closed-book, computer-based exam consisting of 220 multiple-choice questions. It is administered in two 3-hour sessions (an AM session and a PM session) with a scheduled break in between. Testing is conducted online using secure remote proctoring.

How much does the CDMRE MCQ Exam cost?

The fee for the MCQ component is $900 CAD plus $45 GST, making the total fee $945 CAD. This fee is subject to change and must be paid in Canadian funds via credit card or e-transfer at the time of application.

What is the passing score for the CDMRE MCQ?

There is no fixed passing percentage (such as 70% or 75%). The passing mark (cut score) is psychometrically determined for each specific exam administration using a criterion-referenced method (e.g., Modified Angoff). This ensures that the passing standard accounts for the relative difficulty of the questions on that particular test version.

What are the eligibility requirements to write the CDMRE MCQ?

To write the exam, you must have graduated from an approved 3-year Denturism diploma program in Canada (such as George Brown College, NAIT, or CDI College) or have a recognized foreign equivalent. You must also obtain application approval from the provincial regulatory body through which you are seeking licensure.

What happens if I fail the CDMRE MCQ?

Candidates who fail are allowed to retake the exam, subject to the policies of their provincial regulatory college. Most provinces allow up to three total attempts. Re-registering requires submitting a new application and paying the full MCQ examination fee again.
