Which of the following is likely to occur if the VDO is increased in a
complete denture patient?
1. Loss of lip fullness
2. Decreased nose-chin distance
3. Limited tongue space
4. Clicking of teeth
Prosthodontics
Answer: 4
Explanation: Increasing the VDO can lead to increased vertical clearance between
the teeth, potentially causing them to click during function. This can also
affect the patient's speech and the stability of the denture. It is important to
carefully evaluate and adjust the VDO to minimize these issues.

Recontouring and selective grinding procedures are carried out in complete denture to
1) Decrease the vertical dimension of occlusion
2) Decrease cuspal height
3) Enhance curve of Spee
4) Remove occlusal disharmony
Prosthodontics
Answer: 4
Recontouring and selective grinding are procedures used to adjust the fit and function of complete dentures. These adjustments are often performed to eliminate any interference with the patient's normal masticatory (chewing) function or to correct any imbalances in the bite. By removing excess material and reshaping the occlusal surfaces, the dentist can address issues such as malocclusion or improper contact between teeth, thereby restoring a harmonious occlusion.
