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 micromovements and micro-leakage in the abutmentimplant 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.
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 micromovements and micro-leakage between implant components are the main reasons for maintained healthy peri-implant tissues and preserved marginal bone levels.
