The Straumann PURE Ceramic Implant is indicated for the restoration of single-tooth gaps and in edentulous or partially edentulous jaws. The prosthetic restorations used are single crowns, fixed partial or full dentures, which are connected to the implants through the corresponding components.
Closure and Healing caps are intended for use with the Straumann Dental Implant System (SDIS) to protect the inner configuration of the implant and maintain, stabilize and form the soft tissue during the healing process. Closure and Healing caps should be used only with suitable implant connections. Do not use healing components for longer than 6 months.
The provisional components are intended to serve as a base for temporary crown or bridge restoration out of occlusion for the Straumann® PURE Ceramic Implant System. The Straumann® Temporary Abutment VITA CAD-Temp® for the Straumann® PURE Ceramic Implant is indicated for temporary usage of up to 180 days.
CI RD Straumann PUREbase abutment is a titanium base placed onto Straumann ceramic dental implants to provide support for customized prosthetic restorations and is indicated for screw-retained single tooth or cement-retained single tooth and bridge restorations. All digitally designed copings and/or crowns for use with the Straumann® Variobase Abutment system are intended to be sent to Straumann for manufacture at a validated milling center.
The Straumann PURE Ceramic Implant is a dental implant made out of yttrium-stabilized zirconium dioxide (Y-TZP). The Straumann PURE Ceramic Implant is based on features of the Straumann PURE Ceramic implant Monotype. Straumann PURE Ceramic Implants can be placed using the existing instruments using the same osteotomy preparation protocol as for Bone Level implants. The subject implant is a two -piece implant and is available in Ø4.1 mm with lengths of 8, 10, 12, and 14 mm.
The Closure and Healing caps are screws machined as one piece and come in three gingival heights to accommodate individual gingival thickness. The material of the devices is titanium grade 4. The Closure caps are screwed into the implant to protect the inner configuration and shoulder of the implant during the healing phase in cases of submerged (submucosal) healing protocols and do not support a prosthetic restoration. Healing caps are screwed into the implant to protect the inner configuration in cases of transmucosal healing protocols and are placed out of occlusion and do not support a prosthetic restoration.
The Temporary Abutments are used to serve as a temporary crown or bridge restoration for the Straumann PURE Ceramic Implant System.
