Principles of Implant Occlusion: Part 2 – Recommendations for Single Implant Prostheses

Principles of Implant Occlusion: Part 2 Recommendations for Single Implant Prostheses
Launch Course

Course Objectives (1 CE Credit)

Randolph R. Resnik, DMD, MDS

The ideal occlusal scheme for an implant prosthesis is designed to control the biomechanical stress on the implant system, provide a prosthetic and biologically acceptable implant interface, and maintain long-term stability of the marginal bone, soft tissue and prosthesis. Dr. Randolph Resnik discusses the principles of implant-protected occlusion and presents specific recommendations for achieving an ideal occlusal scheme for the single implant prosthesis. Topics include:

  • Optimizing occlusal schemes through implant positioning and crown design
  • Differences between ideal and overly large occlusal tables
  • Comparisons of natural teeth and implant crowns
  • How cusp inclination factors into occlusion
  • Evaluation of occlusal contacts under various biting forces
  • The consequences of cantilever forces on implant systems
  • The effects of an increased proximal contact area
  • Mutually protected occlusion

Summary

Because of the inherent differences between teeth and implants, careful attention must be given to the development and modification of occlusal schemes for single implant prosthetic rehabilitation. The principles of implant-protected occlusion, a concept developed by Dr. Carl Misch, address several conditions to decrease stress to the implant system. Clinicians should incorporate these principles into their implant restorations to maintain forces within physiologic limits and to provide long-term stability of the implant system.

CAUTION: When viewing the techniques, procedures, theories and materials that are presented, you must make your own decisions about specific treatment for patients and exercise personal professional judgment regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
