Correct answer: C — Excessive occlusal vertical dimension

Clicking, muscle fatigue, and minimal freeway space after new complete dentures indicate excessive occlusal vertical dimension. Insufficient vertical dimension more often produces overclosure, angular cheilitis, and reduced facial support. The teaching point is that phonetics, freeway space, facial appearance, and comfort should be assessed together when setting vertical dimension.
