What should be the initial focus when adjusting occlusion for complete dentures?

  1. Restorative adjustments

  2. Centric occlusion

  3. Balancing occlusion

  4. Esthetic adjustments

The correct answer is: Centric occlusion

When adjusting occlusion for complete dentures, the initial focus should be on centric occlusion. This is the occlusion that occurs when the upper and lower dentures are in maximum contact, representing a stable and repeatable occlusal position. Achieving proper centric occlusion is crucial as it establishes the foundation for functional and comfortable dentures, promoting efficient chewing and speaking while minimizing the risk of sore spots or instability of the dentures. By ensuring that the occlusion is set accurately in the centric position, clinicians can assess how the dentures function during various movements, which can then guide subsequent adjustments. The correct positioning in centric occlusion is necessary before addressing other aspects like balancing occlusion, restorative adjustments, or esthetic adjustments, as these elements build upon the foundational occlusal stability provided by centric occlusion.
