Prosthodontics & Occlusion · single question

Which occlusal scheme is most appropriate for this fixed partial denture?

  1. Canine guidance
  2. Incisive guidance
  3. Mutually protected occlusion
  4. Bilateral balanced occlusion
Show answer and explanation

Correct answer: C. Mutually protected occlusion

Mutually protected occlusion is the concept in which anterior teeth protect the posteriors during excursions (disclusion) and posteriors protect the anteriors in maximum intercuspation. This is the standard preferred scheme in fixed prosthodontics — especially when implants are present, because implants tolerate axial loading best and minimal lateral forces.10. Periodontics
