Healing times for dental implants could be cut
Date:6/14/2011

rent surface topographies. The method can be used in the development of new dental implants to optimise the properties for increased bone formation and healing. She has also studied the oxide's conductivity, and the results show that a slightly higher conductivity results in a better cell response and earlier deposition of minerals that are important for bone formation.

The results are in line with animal studies and clinical trials of the commercial implant OsseoSpeed (Astra Tech AB), which show a slightly higher conductivity for the oxide and also an exchange between hydroxide and fluoride on the surface of the oxide. Surfaces with a well-defined nanostructure have a larger active area and respond quickly to the deposition of bone-forming minerals.

The project is a collaboration between the University of Gothenburg and Astra Tech AB in Mlndal, and will be further evaluated in follow-up studies.
