Titania-Y-TZP biocomposites and their in vitro studies

Bioactive ceramics have the ability to form chemical bonding with bone, resulting in good interfacial attachment between an implant and its surrounding bone. Sol-gel derived titania is known to be bioactive. The limitation of the current bioactive ceramics, including titania, is the lack of high mec...

Description
Summary:Bioactive ceramics have the ability to form chemical bonding with bone, resulting in good interfacial attachment between an implant and its surrounding bone. Sol-gel derived titania is known to be bioactive. The limitation of the current bioactive ceramics, including titania, is the lack of high mechanical properties. Yttria stabilised tetragonal zirconia polycrystals (Y-TZP), on the other hand, is well known for its good biocompatibility and high fracture toughness. Therefore, there is an interest to produce titania-Y-TZP composites, with the aim of achieving both desirable bioactivity and mechanical properties.
