Principles of Implant Occlusion: Part 4 – Recommendations for Removable Implant Prostheses

Principles of Implant Occlusion: Part 4 - Recommendations for Removable Implant Prostheses
Launch Course

Course Objectives (1 CE Credit)

Randolph R. Resnik, DMD, MDS

Ideal occlusion is of paramount importance for the long-term success of removable implant prostheses. Most existing occlusal guidelines for removable implant prostheses are derived from principles established for conventional removable prostheses, rather than based on the type and support system of the specific implant overdenture. Dr. Resnik discusses the various factors related to treatment planning for removable implant prostheses, including recommendations for an ideal occlusal scheme with respect to the type of overdenture. Topics include:

  • Treatment planning factors
  • The support system of specific overdenture types
  • Occlusion principles for removable implant prostheses
  • Occlusal recommendations based on the opposing arch
  • The rationale for bilateral balanced occlusion
  • Benefits of medial-positioned lingualized occlusion

Summary

Adherence to the principles differentiating an RP-4 vs. RP-5 implant prosthesis should be followed for optimal long-term function of the removable implant prosthesis. Because patients with removable implant prostheses have been shown to have difficulties in recognizing occlusal prematurities, the occlusal contacts should be strictly monitored and evaluated on a consistent basis to maintain stability and decrease any occlusal disharmony. The proper occlusal scheme, as well as the ultimate success of the implants and the prosthesis, is based on careful treatment planning and the consideration of various factors and principles, which will allow for longevity of the restoration and harmony with the surrounding tissues.

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