## Indications for use
Straumann® Variobase™ prosthetic components directly connected to the endosseous dental implants are indicated for use as an aid in prosthetic rehabilitations. The prosthetic restoration (bridge or over-denture) can be cemented on the Straumann® Variobase™ prosthetic components. A temporary restoration can be used prior to the insertion of the final components to maintain, stabilize and form the soft tissue during the healing phase. They may not be placed into occlusion. Final abutments and restorations may be placed into occlusion when the implant is fully osseointegrated.
