Accurate occlusion testing is essential for the success of dental restorations. Proper testing ensures that restorations fit well, function correctly, and do not cause discomfort or damage to surrounding teeth.

Understanding Occlusion

Occlusion refers to how upper and lower teeth come together when biting or chewing. Proper occlusion distributes forces evenly, preventing excessive pressure on any single tooth or restoration.

Preparation for Occlusion Testing

Before testing, ensure the restoration is fully set and polished. Remove any excess material that might interfere with accurate contact points. Use articulating paper to visualize contact points.

Tools Needed

  • Articulating paper
  • Articulator (if applicable)
  • Mirror and explorer
  • Gently loaded patient bite

Performing Occlusion Testing

Have the patient gently close their mouth to make contact with the restoration. Use articulating paper to mark contact points. Check for high spots or uneven contacts.

Adjust the restoration using a fine diamond bur or polishing instrument. Repeat the process until contact points are evenly distributed and comfortable for the patient.

Verifying Adjustments

Reassess occlusion after each adjustment. Ask the patient to perform lateral and protrusive movements to ensure no interferences occur during functional movements. Confirm that contacts are light and evenly distributed.

Tips for Accurate Testing

  • Use consistent biting pressure when testing.
  • Always compare the restored side with the opposite side for symmetry.
  • Instruct patients to avoid grinding or clenching during testing.
  • Document the contact points for future reference.

Performing precise occlusion testing helps ensure the longevity and functionality of restorations. Regular practice and attention to detail are key to achieving optimal results.
