Prosthodontics - 3 Questions

1
Prosthodontics
All of the following are true regarding the use of cast circumferential clasps, except that, the 1. retentive clasp terminal should originate occlusal to the height of contour 2. retentive terminal should always point towards the gingiva 3. clasp arm should be kept as low on the tooth as possible 4. all of the above

📝 Explanation:

In the design of cast circumferential clasps, the retentive terminal should ideally point away from the gingiva (toward the occlusal surface) to allow for proper engagement and retention without causing trauma to the gingival tissue.

Prosthodontics
When setting teeth for a complete denture in bilateral balanced occlusion, if the incisal guidance is steep, the
1 occlusal plane should be shallow
2 compensating curve should be steep
3 cuspal inclines should be shallow
4 condylar guidance should be made steep

📝 Explanation:

Explanation: In bilateral balanced occlusion, if the incisal guidance is steep, it is necessary to create a compensating curve that is also steep to maintain balanced occlusion during lateral movements. This helps to ensure that the occlusal contacts remain balanced and stable, preventing tipping or dislodgment of the denture during function. The other options do not adequately address the need for balance in occlusion.
