Astra Tech Implant System

Astra Tech Implant System™

To design a successful implant system, one needs not only a great deal of knowledge about biology and mechanics, but also an understanding of what happens when the two interact. Early on in the development of the Astra Tech Implant System™, we realized the value of a holistic approach. That is why our system is uniquely based not only on a biological but also a biomechanical approach. When introducing the OsseoSpeed™ surface with a unique nanoscale topography, we took this to the next level by incorporating biochemistry.

Astra Tech BioManagement Complex™

Just as in nature, a successful existence cannot be determined by one single element alone. The terms biomechanics and biochemistry are no longer sufficient as there must be several interdependent features working together. This interaction is what we call the Astra Tech BioManagement Complex™.

The establishment and maintenance of a soft tissue seal around the transmucosal part of an implant (i.e. the abutment) is vital for implant treatment success. The formation of the soft tissue barrier around the abutment is fundamentally a result of wound healing.

Thus, during healing a barrier epithelium will form adjacent to the abutment. Apical to this epithelium, a zone of connective tissue will form and attach to the titanium surface on the abutment to protect the underlying bone tissue. The barrier epithelium and the connective tissue–implant interface will consequently establish a certain biological width of the peri-implant mucosa. It is important that this process takes place undisturbed, without micro-movements and micro-leakage in the abutment-implant connection, for optimal healing and long-term result.

Nature itself takes care of the soft tissue sculpturing, as long as it is provided with the right conditions, maintained marginal bone levels and healthy soft tissue. With the Astra Tech Implant System you can count on optimal soft and hard tissues.

Initial bone healing and long-term maintained marginal bone levels are affected by the implant design and surface properties. Optimal biomechanical and biochemical stimuli from the implant surface are of the utmost importance for the bone healing process.

Astra Tech BioManagement Complex™

The long-term marginal bone maintenance level is primarily dependent on biomechanical stimulation from the implant, particularly around the implant neck. This means that a successful clinical result, in both the short and long term, is related to the features of the implant.

Failing to control these factors causes marginal bone loss and problems such as black triangles between teeth and, in a worst case scenario, the implant might be lost. Infection or irritation of the soft tissue can also disturb the healing process and the long-term result. These problems might be caused by factors not related to the implant as such, but to a lack of proper maintenance and care by the patient or by his or her general health status. But it can also be caused by micro-leakage and micro-movements due to a less favorable implant design. Our way of safeguarding a reliable, predictable and esthetic short- and long-term result, is with the Astra Tech BioManagement Complex™.

This is a unique combination of the following features: OsseoSpeed™, MicroThread™, Conical Seal Design™, Connective Contour™.

The unique soft tissue seal on the abutment level, together with biomechanical interactions with the bone around the implant neck, ensure optimal conditions for the bone and soft tissue. The load distribution and the lack of micro-movements and micro-leakage between implant components are the main reasons for maintained healthy peri-implant tissues and preserved marginal bone levels.

The benefits of OsseoSpeed™ TX implants

With the OsseoSpeed™ TX implants the biological, biochemical and biomechanical prerequisites are optimized to create excellent results, both in the initial healing phase and in a long-term perspective. The growing power of OsseoSpeed makes it a perfect solution for all your implant patients:

  • Predictable results for all patients, including compromised cases, where implants with other surface treatments may be less effective.
  • Allows for implant treatment in all indications.
  • Improved biological support for immediate installation and early loading protocols.

Building on success – the OsseoSpeed™ surface

We all know that the surface of the implant is an active component in clinical success. And the general consensus is that a rough surface is superior to a more smooth surface. Since 1990, all Astra Tech implants have featured a well-defined rough surface called TiOblast™, offering proven biomechanical benefits in terms of bone formation and implant retention. In fact, we are the only implant provider with up to ten years of clinical follow-up of a defined "micro-roughened" implant surface.

Building on success – the OsseoSpeed™ surface

More bone more rapidly

Building on the proven success of TiOblast, OsseoSpeed is the first and only implant in the world with a chemically modified titanium surface that stimulates early bone healing and speeds up the bone healing process. The result of the micro-roughened titanium surface treated with fluoride is increased bone formation and stronger bone-to-implant bonding. Together with MicroThread™ on the implant neck, OsseoSpeed provides true growing power in action for a more reliable and effective treatment. The benefits of OsseoSpeed are scientifically proven and well-documented.

Outstanding clinical results

The characteristics and properties of the OsseoSpeed surface have been reviewed in numerous published articles revealing positive bone response and optimal clinical results. Results from the extensive OsseoSpeed clinical study program, show good functionality, and predictable and maintained marginal bone levels with a mean marginal bone loss of only 0.3 mm. There is no significant dip in Implant Stability Quotient values traditionally seen at implants 2–6 weeks after installation. This is interpreted as a continuous gain in osseointegration and stability. Published data show that the OsseoSpeed implant can be safely used with a reported survival rate of 94.5% to 100%, including the use of immediate loading protocol even in the atrophic edentulous maxilla, in sinus lifted maxillary posterior jaw sites, immediate installation in extraction sockets and implants placed in atrophied mandibles close to the nerve. OsseoSpeed is suitable for all implant patients and FDA cleared indications include that OsseoSpeed is especially indicated for use in soft bone applications where implants with other surface treatments may be less effective. Three- and five-year clinical follow-up of OsseoSpeed confirms the excellent results*. Do you want to have a complete list of solid evidence? Visit

MicroThread™ – biomechanical bone stimulation

The neck of Astra Tech implants is designed with MicroThread™ – minute threads that offer optimal load distribution and stress values. This design is based on a thorough understanding of bone physiology, which is vital to optimal implant design. Since bone tissue is designed to carry loads, dental implants must be developed to mechanically stimulate the surrounding bone in order to preserve it, taking into consideration that the critical point of the implant-bone interface is located at the marginal cortical bone where peak stresses occur.

Conical Seal Design™ – strong and stable fit

The Conical Seal Design™ is a conical connection under the marginal bone level that transfers the load deeper down in the bone. Compared to conical connections above the marginal bone and flat-to-flat designs, Conical Seal Design reduces peak stresses and thereby preserves the marginal bone.

Conical Seal Design™ – strong and stable fit

It also seals off the interior of the implant from the surrounding tissue, minimizing micro-movements and micro-leakage. Conical Seal Design simplifies maintenance and ensures reliability in all clinical situations. What's more, the tight and precise-fitting implant-abutment relation of the Conical Seal Design makes abutment connection a quick and simple procedure. The abutment is self-guiding and the installation procedure is non-traumatic, helping to eliminate the risk of bone damage.

Connective Contour™ – increased soft tissue contact zone and volume

The Connective Contour™ is the unique contour that is created when you connect the abutment to the implant. This contour allows for an increased connective soft tissue contact zone both in height and volume, which integrates with the transmucosal part of the implant, sealing off and protecting the marginal bone.
