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.
Which class of RPD is characterized by the absence of an axis of rotation?
1) Class I
2) Class II
3) Class III
4) Class IV
Prosthodontics Answer: 3
Class III RPDs do not have a significant axis of rotation due to their design, which allows for better load distribution across the remaining teeth compared to Class I and II RPDs.

In anterior teeth "rests" are ideally prepared and located on
1) Incisal edges
2) Lingual surfaces
3) Mesial surfaces
4) Distal surfaces
Prosthodontics
Answer: 2
In anterior teeth, "rests" are ideally prepared and located on the lingual surfaces. This is because the lingual surfaces provide better support for the denture and distribute the occlusal forces more evenly across the palatal mucosa, reducing the risk of denture movement and discomfort.
