## Indications for use
Straumann® Variobase™ for Bridge/Bar Cylindrical prosthetic components directly connected to the endosseous dental implants are indicated for use as an aid in prosthetic rehabilitations. The patient-specific prosthetic restoration (bridge or over-denture) can be cemented on the Straumann® Variobase™ for Bridge/Bar Cylindrical 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. Temporary restorations are indicated to be placed out of occlusion. Straumann® Variobase™ for Bridge/Bar Cylindrical and patient-specific restorations may be placed into occlusion when the implant is fully osseointegrated. All digitally designed Straumann® Variobase® for Bridge/Bar Cylindrical prosthetic components are intended to be sent to Straumann for manufacture at a validated milling center.
