Question

denture framework to fit tighter in the mouth than on
the cast?

cast.
B. Not enough water in the mix of the stone for

C. Duplication impression slightly oversized.
D. Improper wax-up of the partial denture

Answer 1

Factors that could cause a partial denture framework to fit tighter in the mouth than on the cast are too much water in the mix of the stone for the cast, not enough water in the mix of the stone for the cast, and duplication impression slightly oversized.

Step-by-step explanation:

Factors that could cause a partial denture framework to fit tighter in the mouth than on the cast are:

• Too much water in the mix of the stone for the cast
• Not enough water in the mix of the stone for the cast
• Duplication impression slightly oversized

If there is too much water in the mix of the stone used to create the cast, it can lead to expansion of the material, causing the framework to fit tighter in the mouth. Conversely, if there is not enough water in the mix, the stone can shrink, leading to a looser fit. Additionally, if the duplication impression used to create the cast is slightly oversized, it can result in a tighter fit of the framework in the mouth.
