Open the CIPO recordAbstract From the Canadian patent
The invention relates to an implant element for permanent anchorage in bone tissue in which at least the surface intended to face the tissue in the implantation region is made of a biocompatible material such as titanium and having a clinically well documented surface. The element is provided with a thin, uniform and adherent calcium-phosphate coating with a well controlled dissolution rate. The coating follows the topography of the underlying well documented surface in order to combine properties for rapid bone growth during the healing phase and properties for a guaranteed long-term stability during clinical loading conditions.

Why it's free to use
- Filed April 29, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 29, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 29, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
