, 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
