B. Improved adhesive, cohesive, and viscosity characteristic of the interfacial film layer.
C. Elimination of voids occurring in the interfacial space due to inaccurate intaglio surface contact.

B. Start with a denture surface that is clean and dry.
C. In the maxillary denture dispense a large amount of adhesive along the ridge crest area.
D. Limit adhesive application to the anterior aspect of the mandibular denture.
Once dispensed onto the denture's intaglio surface, how should the adhesive be manipulated?
A. Simply seat the denture using heavy pressure.
B. Allow time for the adhesive to warm on the denture surface to facilitate adhesion.
C. Evenly disperse the adhesive over the entire intaglio surface with a clean, dry finger.
D. No additional manipulation is necessary.
After applying adhesive to the denture's intaglio surface and immediately prior to placing the denture in the mouth, what step(s) should be accomplished?
A. Place the denture in a warm, dry place for 20-25 minutes.
B. Submerse the denture in cool water to hydrate the adhesive.
C. Allow warm water from a faucet to flow over the adhesive for 4-5 seconds.
