The main advantage of bioglass ceramics is that CaO and P2O5 can be introduced into the glass. Hydroxyapatite crystals can be precipitated by heat treatment. It has excellent biocompatibility and bioactivating properties, and other components in the composition can precipitate other components. Types of crystals ensure the chemical stability and machinability of materials, and are more promising than metals, alumina and Other Materials
. Many clinical trials have been conducted to date, some for six years, and have yielded promising results.
