,Q1. A patient presents with a severely resorbed mandibular ridge and a history of unstable complete
dentures. The denturist is considering a lingualized occlusion scheme. Which of the following best describes
the biomechanical advantage of this approach?
A. It eliminates all lateral forces by using 0-degree teeth.
B. It concentrates occlusal contacts on the lingual cusps of maxillary posterior teeth, reducing tipping forces on
the mandibular denture.
C. It provides maximal intercuspation in centric relation only.
D. It uses anatomic teeth with steep cuspal angles to enhance chewing efficiency.
Correct Answer: B. It concentrates occlusal contacts on the lingual cusps of maxillary posterior teeth,
reducing tipping forces on the mandibular denture.
Rationale: Lingualized occlusion focuses contacts on the maxillary lingual cusps, minimizing lateral forces on the
mandibular ridge. This is especially beneficial for severely resorbed ridges. Option A is incorrect because lateral
forces are reduced, not eliminated. Option C is too narrow; lingualized occlusion works in eccentric movements as
well. Option D describes a different (anatomic) scheme that increases lateral forces.
Why Wrong:
A - Elimination of all lateral forces is not possible; 0-degree teeth reduce but do not eliminate them.
C - Lingualized occlusion is designed for function in eccentric movements, not just centric relation.
D - Steep cuspal angles increase lateral forces, counterproductive for resorbed ridges.

Q2. A denturist is evaluating a patient with a history of recurrent aphthous ulcers and a new complete
denture. The patient reports persistent sore spots despite multiple adjustments. Intraoral examination reveals
erythematous areas with white, lacy striae on the buccal mucosa bilaterally. Which of the following is the
most likely diagnosis?
A. Denture stomatitis
B. Oral lichen planus
C. Angular cheilitis
D. Epulis fissuratum
Correct Answer: B. Oral lichen planus
Rationale: The presence of white lacy striae (Wickham striae) on the buccal mucosa is pathognomonic for oral
lichen planus, a chronic inflammatory condition. Denture stomatitis (A) presents as erythema under the denture
base, not striae. Angular cheilitis (C) involves the corners of the mouth. Epulis fissuratum (D) is a fibrous
hyperplasia from ill-fitting denture flanges.
Why Wrong:
A - Denture stomatitis appears as diffuse erythema under the denture, not striae on the buccal mucosa.
C - Angular cheilitis is characterized by fissures and erythema at the oral commissures.
D - Epulis fissuratum is a rolled fibrous tissue along the denture flange, not lacy striae.

Q3. During a try-in appointment for a maxillary complete denture, the denturist notices that the midlines of
the central incisors are shifted 2 mm to the patient's left relative to the facial midline. The patient has a Class
I skeletal relationship and no facial asymmetry. Which of the following is the most appropriate adjustment?
A. Reset the six anterior teeth to align the midline correctly.
B. Reposition only the left central incisor by grinding its mesial surface and adding composite.
C. Reposition only the right central incisor by grinding its distal surface and adding composite.
D. Accept the shift if the patient does not notice it, as it is within normal variation.
Correct Answer: A. Reset the six anterior teeth to align the midline correctly.
Rationale: A 2 mm midline deviation is clinically significant and should be corrected. Resetting the six anterior
teeth ensures proper alignment and symmetry. Options B and C would create disproportionate tooth sizes and
Page 3
, asymmetry. Accepting the shift (D) is not ideal as it compromises esthetics and may be noticeable. Resetting is the
standard approach for a try-in.
Why Wrong:
B - Altering only one tooth would result in mismatched widths and asymmetry.
C - Same as B; unilateral adjustment disrupts tooth proportions.
D - A 2 mm deviation is clinically significant and should be corrected for optimal esthetics.

Q4. A denturist is fabricating a mandibular complete denture using a metal base framework for added
strength. Which of the following cast alloys is most appropriate for this application, considering
biocompatibility, rigidity, and cost?
A. Type III gold alloy
B. Cobalt-chromium alloy
C. Nickel-chromium alloy
D. Titanium alloy
Correct Answer: B. Cobalt-chromium alloy
Rationale: Cobalt-chromium alloy offers high rigidity, excellent biocompatibility, and lower cost compared to gold.
It is the standard for metal denture bases. Type III gold (A) is too soft and expensive. Nickel-chromium (C) poses
nickel allergy concerns. Titanium (D) is biocompatible and lightweight but more expensive and difficult to cast.
Why Wrong:
A - Type III gold is too soft for a thin denture base and costly.
C - Nickel-chromium alloys can cause allergic reactions in nickel-sensitive patients.
D - Titanium has high biocompatibility but is more costly and requires specialized casting equipment.

Q5. A patient with a complete denture reports a burning sensation on the palate and angular cheilitis. On
examination, there is diffuse erythema under the maxillary denture base, and a culture reveals Candida
albicans. The patient has a history of hypertension and is taking lisinopril. Which of the following is the most
appropriate initial treatment?
A. Prescribe nystatin oral suspension and instruct the patient to remove the denture at night.
B. Prescribe fluconazole 200 mg daily for 7 days and continue denture wear.
C. Replace the denture immediately to eliminate the reservoir of infection.
D. Apply topical clotrimazole cream to the palate and discontinue lisinopril.
Correct Answer: A. Prescribe nystatin oral suspension and instruct the patient to remove the denture at
night.
Rationale: Denture stomatitis with Candida is best treated with topical antifungal (nystatin) and denture hygiene
(night removal). Fluconazole (B) is systemic and may interact with lisinopril. Immediate denture replacement (C) is
not necessary; the denture can be disinfected. Discontinuing lisinopril (D) is inappropriate as it is not the cause.
Why Wrong:
B - Fluconazole is systemic and increases risk of drug interactions; topical therapy is first-line.
C - Replacement is not indicated; the denture can be disinfected with chlorhexidine.
D - Lisinopril is not associated with candidiasis; discontinuing it is not warranted.

Dentures, J Prosthodont, 20(S1)
Q6. Which of the following best describes the purpose of a facebow transfer in complete denture fabrication?
A. To record the relationship of the maxilla to the temporomandibular joint and transfer it to the articulator.
B. To measure the vertical dimension of occlusion.
C. To record centric relation at the correct vertical dimension.
