The main objective of the new system is to further improve system logic, robustness and user friendliness, and simplicity without compromise has permeated the evolution of the Astra Tech Implant System EV. The new system is also the result of collaborative input and insights from dental professionals throughout the global dental industry.

“When we develop new implant therapy solutions, it is important that they meet actual clinical needs. With our solutions, clinicians are able to solve these various challenges and, as a result, they can deliver long-term function and aesthetics to their patients. Our focus is to deliver safe, well-documented solutions and the best service to our customers,” says Björn Delin, DDS, and Vice President Global Platform Implant Systems at Dentsply Sirona Implants.

The foundation of this evolutionary step is the unique Astra Tech Implant System BioManagement Complex, well documented for its long-term marginal bone maintenance and aesthetic results provided by the combination of four key features: the OsseoSpeed surface, MicroThread, Conical Seal Design and Connective Contour.

Astra Tech Implant System EV highlights:
• Versatile implant assortment
• Flexible drilling protocol that allows for preferred primary stability
• User-friendly surgical tray with three interchangeable overlay options
• Colour-coded assortment
• Unique interface with one-position-only placement of Atlantis patient-specific abutments
• Self-guiding impression components
• One system—one torque

OsseoSpeed® Profile implants
Almost 40% of all implant sites present with a sloped alveolar ridge after healing. The OsseoSpeed Profile EV implant (Astra Tech Implant System) is a uniquely shaped, patented implant specifically designed for just this clinical situation. It is designed to follow the natural shape of the bone, supporting the soft tissue by preserving marginal bone 360 degrees around the implant. In addition, it can help to eliminate the need for bone augmentation procedures; 58% of all sloped implant sites have a reduced need for augmentation when using the OsseoSpeed Profile implant.

OsseoSpeed Profile EV is the second generation of the uniquely shaped, patented implant specifically designed for sloped ridge situations that was first introduced in 2011. The implant is now upgraded with the simplicity and design principles of the Astra Tech Implant System EV.
Newly published results on OsseoSpeed Profile implants show bone preservation, increased soft tissue volume and regain of keratinized mucosa in patients with compromised soft tissue conditions. PD Dr. Robert Nölken, co-author of the study, explains “We have seen a great deal of improvement on the peri-implant soft tissue in our research follow-up. This allows us to achieve a good aesthetic outcome for patients with thin biotypes.”

This prospective, 2-year follow-up, multicenter study— investigated OsseoSpeed Profile EV implant survival rate, soft and hard tissue maintenance following placement in healed sites of the posterior mandible. Twenty-four centers, 184 patients and 238 implants were included in the study that showed >99% overall survival rate and an average bone level reduction of 0.3 mm.1

The SmartFix concept
SmartFix is a treatment concept that can provide edentulous patients with an immediate fixed, full-arch prosthesis, supported by only four implants. The SmartFix concept includes an angulated abutment that comes together with a short and flexible abutment holder for easier handling. The option of angulating the screw access channel through the prosthesis opens up for ideal aesthetics and function.

This concept is an easy and cost-effective treatment that offers improved treatment satisfaction for the patient and practice growth for the dental professional.

SmartFix is available for the Astra Tech Implant System EV, including OsseoSpeed Profile EV.
