Most occlusal splints have one primary function; what is it?

  1. To alter an occlusion so it does not interfere with complete seating of the condyles in centric relation
  2. To increase the vertical dimension, taking all the loading forces off the TMJs and transferring the load to the teeth
  3. To relieve symptoms of orofacial pain since direct occlusal equilibrium does not have the same potential for the relief of symptoms
  4. To avoid having to remove any tooth structure by equilibrating the teeth to perfect the occlusion

Answer(s): A



What is the principal determinant of posterior occlusal form?

  1. Elevator muscles
  2. Vertical dimension
  3. Anterior guidance
  4. Lateral excursions

Answer(s): C



Functional occlusion is influenced by side shift as follows: the greater the side shift, the restoration fabricated should exhibit:

  1. Wider cusps on posterior teeth.
  2. Longer cusps on posterior teeth.
  3. Wider fossas and marginal ridges.
  4. Improved strength to withstand balancing interferences.

Answer(s): A



In what position of the TMJ can the mandible accept firm compressive loading with no signs of tenderness or tension?

  2. Centric occlusion
  3. Lateral excursion
  4. Maximum opening

Answer(s): A
