Prosthodontics & Occlusion · single question
A patient's complete denture moves from SIDE TO SIDE during use. Which prosthetic quality is primarily affected?
Show answer and explanation
Correct answer: B. Stability
STABILITY = resistance to HORIZONTAL (lateral) movement of denture base. Side-to-side movement = inadequate stability. RETENTION = resistance to vertical dislodgement. SUPPORT = resistance to vertical movement toward tissue. Stability depends on: balanced occlusion, base extension, arch adaptation.
