Prosthetic Concept of Resilient Hybrid Bar ConstructionPREAT Corporation
Revax Retained Resilient Hybrid Prosthesis
A bar supported removable prosthesis that is bar and abutment supported in the anterior region, and tissue supported in the posterior region.
- 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 a limited number of implants are present in either the mandible or maxilla, the tissue supported overdenture is a preferred prosthetic option to protect the implant abutments.
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 prosthesis 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 extensions of a bar that primarily splints the implants. The distal support elevations are positioned in the axis of rotation of the resilient hybrid prosthesis.
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.
