Treatment of choice for a patient with a maxillary complete denture with severe bilateral tuberosity undercuts
1. Remove both tuberosity undercuts
2. Remove the tissue on only one side if possible
3. Maintain the undercuts as they help in retention
4. Use an mucostatic impression material

Centric relation is best defined as
1. The relation of the mandible to the maxillary when the teeth are in centric occlusion
2. The retruded contact position (RC)
3. The relation of the mandible to the maxilla when the condyles are in their most posterior position in the glenoid fossae
4. None of the above
Prosthodontics
Answer: 3
Centric relation is best defined as the relation of the mandible to the maxilla when the condyles are in their most posterior position in the glenoid fossae.
Which tooth carries the heaviest load in a complete denture patient ?
1. Second bicuspid
2.First molar
3 Second molar
4 First bicuspid
Prosthodontics
Answer: 1
Explanation: In complete denture patients, the second bicuspid
often carries a significant load during mastication due to its position and the
occlusal forces exerted during chewing. This tooth's location allows it to
support the occlusal forces effectively, making it crucial in the overall
function of the denture.
