Intended Use

The Straumann® PURE Ceramic Implant is indicated for restoration in single tooth gaps and in an edentulous or partially edentulous jaw. The prosthetic restorations used are single crowns, fixed partial or full dentures, which are connected to the implants through the corresponding components. The ø3.3 mm reduced diameter implants are recommended for central and lateral incisors only.

Device Story

Straumann® PURE Ceramic Implants are endosseous dental implants used for tooth replacement. Available in monotype and two-piece designs, they feature a Yttrium-stabilized zirconium dioxide (Y-TZP) body with a ZLA® (sand-blasted, large-grit, acid-etched) surface to promote bone anchorage. Implants are surgically placed into the jawbone by a dental clinician. The device serves as a foundation for prosthetic restorations, including single crowns, fixed partial, or full dentures. The system integrates with corresponding instruments and prosthetic components. The device is non-magnetic and passive, functioning as a structural anchor for dental prosthetics. Clinical benefit includes restoration of oral function and aesthetics in patients with missing teeth. The device is MR Conditional, with compatibility dependent on the specific prosthetic assembly used.

Clinical Evidence
