With our strong focus on research, science and documentation, we have followed the maintenance of the marginal bone level on our own system for many years and noted that the marginal bone levels on Astra Tech implants have been extraordinarily well maintained. When comparing our exceptional result to the current standard norm, it turns out that there is a huge gap between what can be achieved with the Astra Tech Implant System™ and what is currently accepted as a successful treatment result.
Astra Tech Implant System™ level
More than 40 published articles show that the mean marginal bone level reduction when using the Astra Tech Implant System™ is 0.3 millimetres during the first year of loading and after that it is stable. The conclusion is that the Astra Tech Implant System has a mean marginal bone reduction of 0.3 millimetres – a result that is four times better compared to the current standard norm after five years.
Standard norm
The red line in the graph illustrates what has, until now, been perceived as the standard norm for acceptable marginal bone loss related to dental implant treatment. The figures are based on the three different articles stated next to the graph above. The articles describe the acceptable marginal bone loss to be less than 1.0 millimetre during the first year of loading and less than 0.2 millimetres annually during the following year. Thereafter, the marginal bone loss has been described to become stable, resulting in a marginal bone loss of approximately 1.5 millimetres after five years.
