Prosthodontics & Occlusion · single question

At the vertical dimension of occlusion (VDO), the maxillary tuberosity contacts the retromolar pad, preventing adequate denture space. What is the most appropriate treatment?

  1. Surgically reduce the maxillary tuberosity
  2. Surgically reduce the retromolar pad
  3. Avoid acrylic coverage of the maxillary tuberosity
  4. Avoid acrylic coverage of the retromolar pad
Show answer and explanation

Correct answer: A. Surgically reduce the maxillary tuberosity

When the maxillary tuberosity contacts the retromolar pad at the vertical dimension of occlusion, there is insufficient inter-arch space for denture fabrication. The maxillary tuberosity is a bony structure covered by fibrous tissue, and surgical reduction (tuberoplasty) is the appropriate treatment to create adequate space for a properly fitting maxillary complete denture. The retromolar pad is a key anatomical landmark for mandibular denture posterior extension and should be preserved whenever possible. Avoiding acrylic coverage does not address the fundamental space problem.
