How to Incorporate Occlusion Checks During Final Restorations

by

In restorative dentistry, ensuring proper occlusion is crucial for the longevity and success of the final restoration. Occlusion checks help prevent issues like uneven wear, discomfort, and temporomandibular joint (TMJ) problems. Incorporating occlusion checks during final restorations enhances patient outcomes and restores function effectively.

Understanding Occlusion

Occlusion refers to the contact relationship between upper and lower teeth when the jaws are closed. Proper occlusion distributes biting forces evenly, avoiding excessive stress on specific teeth or restorations. An imbalance can lead to restoration failure or discomfort.

Steps to Incorporate Occlusion Checks

  • Initial Assessment: Before finalizing the restoration, evaluate the patient’s existing occlusion. Use articulating paper to identify high spots and contact points.
  • Adjustments During Try-In: During try-in, verify the fit and contact points. Make minor adjustments as needed to achieve even contacts.
  • Use of Articulator: Mount the casts on an articulator to simulate jaw movements. This allows for precise adjustments outside the mouth.
  • Final Occlusion Check: Once the restoration is cemented, perform a thorough occlusion check. Use articulating paper again to confirm proper contact distribution.
  • Dynamic Testing: Have the patient perform lateral and protrusive movements to identify any interferences or high contacts that may cause functional issues.

Tools and Techniques

Utilize various tools to enhance occlusion assessment:

  • Articulating Paper: For visualizing contact points.
  • Shim Stock: To check the intensity of contacts.
  • Occlusal Indicators: Such as disclosing agents for precise adjustments.
  • Digital Occlusion Scanners: For detailed analysis in modern practices.

Best Practices for Successful Occlusion Checks

Adopt these best practices to ensure optimal results:

  • Always check occlusion in centric relation and functional movements.
  • Make incremental adjustments to avoid over-reduction of the restoration.
  • Communicate with the patient about sensations during testing.
  • Document occlusion findings for future reference and case records.

Incorporating systematic occlusion checks during final restorations is essential for durable, comfortable, and functional dental work. Proper assessment and adjustments can significantly improve long-term success and patient satisfaction.
