Taking responsibility for occlusion: the perfect occlusion

Summary

Proper occlusion is rare in healthy patients. When teeth contact during swallowing, forces should align with the long axis of teeth or implants, avoiding contact on incline planes.

Area of Science:

  • Dentistry
  • Biomechanics
  • Dental Occlusion

Background:

  • Occlusal dysfunction is common, impacting oral health.
  • Understanding natural occlusal contacts is crucial for treatment planning.

Purpose of the Study:

  • To define the ideal characteristics of occlusal contacts during function.
  • To establish biomechanical principles for force distribution in the dentition.

Main Methods:

  • Analysis of occlusal contacts during simulated physiological functions.
  • Biomechanical modeling of force vectors on teeth and implants.

Main Results:

  • Simultaneous occlusal contacts are infrequent in healthy dentition.
  • Optimal force vectors during occlusion are directed along the long axis of teeth/implants.
  • Incline plane contacts were found to be non-functional and potentially detrimental.

Conclusions:

  • Restorative dentistry should aim for simultaneous, long-axis-aligned occlusal contacts.
  • Avoiding incline plane contacts is essential for preserving teeth and implants.
  • These findings inform the design of functional occlusion in dental restorations.
