Prosthodontics & Occlusion · single question

When fabricating a new complete denture, increasing the vertical dimension of occlusion excessively most likely causes which clinical sign?

  1. Increased proliferation of Candida
  2. Sore facial muscles and TMJ discomfort with difficulty closing the lips
  3. Improved phonetics
  4. Reduced freeway space without symptoms
Show answer and explanation

Correct answer: B. Sore facial muscles and TMJ discomfort with difficulty closing the lips

Excessive vertical dimension overcloses the freeway space, leading to muscle fatigue and soreness, TMJ discomfort, clicking teeth during speech, and difficulty achieving lip competence.Other options: Candida proliferation relates to tissue trauma/hygiene; phonetics worsen, not improve; the freeway space is reduced and symptomatic.Key exam takeaway: Too much VDO = muscle/TMJ soreness, clicking teeth, lip incompetence, reduced freeway space.
