| Sumario: | Nowadays, an important research topic related with medical devices are the materials designed as bone tissues substitutes. Hard tissues have a great capacity of self-regeneration but in front of traumatic or pathologic critical bone defects it is necessary the use of bone substitutes or templates as temporal or permanent grafts. Glasses or glass-ceramics are osteoconductive, osteoinductive and biocompatible materials. In addition, they have the ability to link directly to the living bone tissues without any interface (bioactivity). Also, it has been reported that bioglasses favor the angiogenesis process and the cellular adhesion, proliferation and differentiation necessary features for bone tissue engineering scaffolds. This work refers generalities of the bioactive glasses and glass-ceramics compositions, manufacture processes, properties, advantages, disadvantages as well as the main clinical applications and new developments for tissue engineering. |
