For a complete denture patient with Class III ridge relation, the freeway space
1. must be increased
2 .must be decreased
3.should be the same as for Class I
4. Do not set teeth for abnormal jaw relations
Prosthodontics
Answer: 2
Explanation: In Class III ridge relations, the freeway space
must be decreased to accommodate the altered jaw relationship and ensure proper
occlusion. This adjustment helps maintain functional stability and comfort for
the patient.
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.

Lateral throat form occupied by retromylohoid flange in lower denture
1) Has nothing to do with the denture
2) Should be large, one-half inch
3) Should be small, less than half inch
4) Should be larger, more than 2 inches
Prosthodontics
Answer: 2
The retromylohyoid area is an important anatomical region in the lower denture that contributes to the retention and stability of the denture. The lateral throat form, which is the space between the retromylohyoid flange and the surrounding tissues, should be adequately large (approximately one-half inch) to allow for proper function and comfort of the denture. A well-formed lateral throat area helps in achieving a good seal and prevents food impaction.

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
Prosthodontics
Answer: 2
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.
