Dentsply Sirona Implants continues to deliver innovation, digital solutions and versatility in implant dentistry. With the latest product developments, the Astra Tech Implant System continues to evolve, based on customer needs and the latest digital technology.

With a comprehensive product and solutions portfolio for all phases of implant dentistry, Dentsply Sirona Implants continually strives to increase the application of implant therapy, based on science and without compromising safety and efficacy.

“The implant solutions that we develop are based on the needs of our customers, as well as centered around our well-documented and clinically proven implant systems. We’re all about providing long-term functional and aesthetic solutions for the many different situations that happen in clinics and laboratories every day all over the world. And we help dental professionals deliver the absolute best care for their patients,” says Gene Dorff, Group Vice President at Dentsply Sirona Implants.

Azento for single tooth replacement
Azento is the latest innovation in the Dentsply Sirona Implants’ implant solutions portfolio, helping implant dentistry professionals with one of their most common indications—single tooth replacement—in implant therapy.

Each patient treated with Azento gets a custom treatment plan, including surgical guide, instruments, drills, a case-specific Astra Tech Implant System or Xive implant, an Atlantis custom healing abutment and an optional temporary restoration.

This digital implant workflow solution streamlines the implant planning, purchasing and delivery of products. For the clinician, this custom implant solution increases convenience, seamlessly and efficiently connects with qualified laboratories, and enables consistent, excellent results for patients.

Introducing Astra Tech Implant EV
The Astra Tech Implant System just got even better—with the new Astra Tech Implant EV. As one of the most well-documented implant systems in the market today—documented in over 1,000 publications in peer-reviewed journals—it continues to evolve and provide great clinical benefits.

In fact, the revised implant design change comes with significant advantages—with a deeper implant thread design apically, it is easier to reach preferred primary stability and the handling experience is enhanced for easy installation.

Dr. Mark Ludlow, Division Director of Implant Prosthodontics and Associate Professor at the College of Dental Medicine at the Medical University of South Carolina, agrees: “You still have all the wonderful properties of TX and EV, but with this new implant, you get better handling that helps hit that primary stability—it literally just sinks into the osteotomy.”

With this new change in design properties also comes the new name—Astra Tech Implant EV. The new implant line will be available starting in the North American market in October 2019 and in the European market in early 2020.

Latest clinical data on Astra Tech Implant System
The Astra Tech Implant System OsseoSpeed implants show excellent long-term clinical results, as described in the article by Windael et. al.** Patients in this study received a total of 105 immediately loaded implants in the edentulous mandible. Minimal bone loss, 100% implant survival and 100% prosthetic survival rates were reported at the 10-year follow-up.

Using short implant is a solution for patients with limited bone that are unwilling or unable to undergo bone grafting. In a recently published study* lead by Professor Hämmerle from the University of Zürich, a randomized clinical multicenter study compared the use of short 6 mm OsseoSpeed implants (Astra Tech Implant System) with 11-15 mm implants and grafting. In the study, they show important benefits when using OsseoSpeed short implants: a simplified surgical procedure (no need for grafting), reduced surgical time (with 30%) and reduced surgical cost (with 50%), and higher patient satisfaction (due to less pain and less complications, as well as cheaper treatment).

Astra Tech Implant System’s OsseoSpeed Profile implant is a solution for sloped ridge situations that can be used instead of bone augmentation. The OsseoSpeed Profile implant has been evaluated in a 10-year study, showing well maintained hard and soft tissue levels. This data will be presented for thefirst time by Dr. Robert Noelken, Germany, at the EAO meeting in Lisbon.

The evolution of the Astra Tech Implant System
Since its launch over 30 years ago, Astra Tech Implant System has been one of the world’s most documented dental implant systems, with over 1,000 published scientific references in peer-reviewed journals. Ongoing clinical documentation demonstrates that Astra Tech Implant System provides surgical and prosthetic flexibility, maintains marginal bone levels, and delivers reliable and predictable clinical results as well as natural aesthetics, in the short and long term.

This top-of-the-line implant system features pioneering and groundbreaking innovations that are the result of knowledge and understanding of the biological and clinical processes involved in dental implant therapy. These innovations, such as implant-abutment connection, surface technology, and implant thread design, contribute to even better clinical results.

It was clear from the beginning that a successful implant system cannot be determined by one single feature alone. Just as in nature, there are several interdependent features working together. Astra Tech Implant System BioManagement Complex™ is the unique combination of key features— OsseoSpeed®, MicroThread®, Conical Seal Design™ and Connective Contour™—that is at the core of Astra Tech Implant System.

With the right design philosophy, you get an implant system that provides the versatility needed to meet the needs of each individual clinical situation. When designing an implant system, several parameters need to be considered: long-term biological and clinical performance, ease of use and tactility, versatility and indication coverage, as well as mechanical integrity and robustness. In addition, the design philosophy of the Astra Tech Implant System EV is based on the natural dentition utilizing a site-specific, crown-down approach. By using the natural dentition as a guide, implants, abutments, and abutment and bridge screws are designed to meet the requirements for mechanical integrity, bone quantity, load carrying capacity and biological response.

This evolutionary step—Astra Tech Implant System EV—was the result of a collaborative input and insights from dental professionals throughout the global dental community: 47 international participants and 700+ implant treatments in 14 countries. And the evolution and true dedication to improving implant dentistry continues today.
