Prosthetic Concept of Rigid Hybrid Bar ConstructionPREAT Corporation
Revax Retained Rigid Hybrid Prosthesis
A bar supported removable prosthesis (bridge) that is resilient or totally abutment supported (rigid).
- A patient removable bridge
- Provides for proper lip support and contours
- Bar provides for abutment splinting
- Tripodization provides for controlled implant loading and prosthesis stability
- Provides for open palate
When an adequate number of well integrated implants are present in an arch, a traditional fixed bridge is the prosthetic modality of choice. Often this is not an option in the maxilla, due to combined vertical and horizontal resorption, quality of bone, and position and/or flare of the implants. In this instance, a traditional fixed bridge would not meet patient requirements for hygiene maintenance, esthetics, phonetics, and comfort. The viable alternative is the rigid supported Revax bar removable prosthesis.
The goal of the prosthetic design is to accomplish excellent esthetics, phonetics, and stabilization of the prosthesis as well as to ensure optimum conditions for oral hygiene and patient comfort.
The hybrid concept is to separate support, lateral stabilization, and retention. Each of these aspects may be altered according to the individual situation without influencing the other aspects.
Support is derived from three elevated areas: on the midline and on the distal of a bar that primarily splints the implants.
Lateral Stability is achieved by incorporating a cast frame into the removable prosthesis that closely fits the bar in a passive state.
Retention is derived from 2 or 4 Ceka Revax attachments with adjustable, serviceable retention without affecting support or stability.
