Why is bioglass used for bone repair?
Bioactive glass is biocompatible and improves the formation of new and strong bones. It has been shown that when bioactive glass is added to bone substitutes, it can boost their efficacy as well as bone healing properties to rival those acquired with autografting.
What are those ions that help produce hydroxyapatite?
The OH− ion can be replaced by fluoride, chloride or carbonate, producing fluorapatite or chlorapatite. It crystallizes in the hexagonal crystal system. Pure hydroxyapatite powder is white….

What are bioactive ceramics?
Bioactive ceramics are generally regarded as ceramics that are designed to induce specific biological activity for repairing damaged organs. For repairing bone tissues, the bioactivity is regarded as the capability to make direct contact with living bone after implantation in bony defects.
How are bioactive glasses used in dentistry?
There is increasing use of bioactive glasses in various aspects of dentistry including dental restorative materials, toothpaste, mineralizing agents, desensitizing agents, pulp capping, root canal treatment, and air abrasion.
What are bioac-tive glasses?
Bioactive glasses can also be used to modify different biocompatible materials that need to be bioactive. This study reviews the significant developments of bioac-tive glasses in clinical application, especially dentistry.
What are the most bioactive glasses?
The most bioactive glasses have superior surface area with higher dissolution rate and thus faster apatite formation. The FDA has approved Bioglass®45S5 and S53P4 for clinical applications due to desired antimicrobial properties.
What determines the bioactivity of glass?
The bioactivity is influenced by the structure and composition of the glass, manufacturing techniques, and the rate of ionic dissolution. The most bioactive glasses have superior surface area with higher dissolution rate and thus faster apatite formation.
