What is a likely outcome of inadequate sealing of flasks when packing denture base resin?

Show Answers

Reduced color durabilityLower amount of polymerization shrinkageRise in the vertical dimensionReduction in the vertical height

Explanation

Improper flask closure during the packing stage of denture base resin leads to an increase in the vertical dimension due to incomplete polymerization and resin flow. This results in dimensional changes affecting the fit and function of the denture.
