Rehabilitation of the Edentulous Mandible With an Immediately Loaded Full-Arch Fixed Prosthesis Supported by Three Implants: A 24-Month Retrospective Analysis of Trefoil concept

RA Rozov and A B Gerasimov

The most significant task of dental rehabilitation of elderly is to ensure high quality of life by creating prosthetic reconstructions with high functionality. And that can often be achieved only with the use of implant-supported prostheses of various types. It is of particular importance for the rehabilitation of edentulous mandible. Implant supported treatment with overdentures that are retained on 1-2 implants and 3-4 implants, splinted by a bar, are quite popular. These overdentures have certain disadvantages, which affect chewing efficiency, and limit their longevity. In addition, removable dentures have been shown to have a negative impact on the mental health of elderly patients. The state-of-the-art concept of implant rehabilitation of edentulous mandible is immediate loading on four implants, two of which are tilted at the angle.

There is a clear interest in the P.I. Branemark (1999) concept of implant rehabilitation of the edentulous mandible using three implants and a standard prefabricated bar fixed to them at the day of surgery that also serves as the framework for the definitive prosthesis. The results of implant-supported rehabilitation significantly improved the quality of life of patients. For that period of the development of the dental practice, these were amazing results. The economic situation in the health care of the European countries and Russia requires cheaper methods of dental rehabilitation of edentulous patients while maintaining high rates of implant survival and quality of life for patients.

That is why we are interested in implementing this concept of implant-supported rehabilitation in prosthetic dentistry.
