ORE Part 2 Prosthetics & Dentures

Question 1

What is the most common cause of denture stomatitis (Newton Type II)?

Accepted Answer

Candida albicans infection under the denture

Answer

Denture stomatitis is predominantly caused by Candida albicans colonising the fitting surface of the denture and inflaming the underlying mucosa, especially with overnight wear.

Question 2

When recording the occlusal vertical dimension (OVD) for a complete denture, which clinical sign is used?

Accepted Answer

Freeway space (rest vertical dimension minus OVD = 2–4 mm)

Answer

Freeway space (interocclusal rest space) of 2–4 mm is the difference between RVD (rest position) and OVD; this guides correct vertical dimension for complete dentures.

Question 3

What is the neutral zone in complete denture construction?

Accepted Answer

The zone where muscular forces from lips, cheeks, and tongue are balanced

Answer

The neutral zone is the space in the edentulous mouth where the inward forces of cheeks and lips are balanced by the outward force of the tongue, guiding denture tooth position.

Question 4

Which occlusal scheme is most commonly prescribed for complete dentures?

Accepted Answer

Balanced occlusion

Answer

Balanced occlusion (bilateral balanced articulation) is the most appropriate complete denture occlusal scheme, providing stability during excursive movements by maintaining contacts on both sides.

Question 5

What is the primary purpose of posterior palatal seal in a complete upper denture?

Accepted Answer

Maintain peripheral seal and retention

Answer

The posterior palatal seal (post dam) creates a continuous seal at the junction of the hard and soft palate, preventing air entry and improving denture retention by suction.
