IONS IN BONE REPAIR

Bioactive glass is actually an old friend, having been developed around 50 years ago. Due to its bone growth promoting properties, it has since been often used in regenerative medicine as a bone replacement material or in dentistry. Image Bioactive glass can be combined with biopolymers for wound treatment. This produces a flexible and transparent material for dressings for chronic wounds, such as those that can occur in patients with diabetes.
