Effective alternation in the abutment with short clinical crowns for proper clasp retention can be achieved by
1) Proper guiding planes
2) Restoring with full crown
3) Altering the height of contour
4) All of the above
Prosthodontics
Answer: 2
When dealing with short clinical crowns in RPD abutment teeth, restoring the teeth with full crowns can provide additional retentive surfaces and support for the clasp. This can be particularly useful when the available undercuts are limited, thereby enhancing the overall stability and retention of the prosthesis.

3. Tissue conditioners are indicated when there is reduction in salivary flow
4. None of the above
Prosthodontics
Answer: 2

Which of the following materials have maximum osseous integration
1) Tantalum and titanium
2) Vitreous carbon
3) Porous aluminium silicate
4) Alumina and sapphire
Prosthodontics
Answer: 1
Maximum osseous integration is a term used in the context of dental implants and refers to the degree to which the bone tissue of the jaw integrates with the implant material. Tantalum and titanium are both biocompatible materials that are known for their excellent osseointegration properties. Titanium is the most commonly used material for dental implants due to its high biocompatibility and strong osseointegration. Tantalum is also biocompatible, but it is not as commonly used as titanium.

4. Hamular process
Prosthodontics
Answer: 1
When determining the posterior limit of the maxillary denture, the hamular notch is on the posterior border.
