Review Article: Zirconia surface bone graft implant with Ultraviolet Stimulation works toward Accelerating Bone Healing

Biomedical zirconia was introduced in 1969 into medicine to solve the problem of alumina brittleness in hip replacement procedures and has since been used for various joint replacement appliances in orthopedic surgery. The most frequently-studied material is yttrium-stabilized zirconia, which is also known as tetragonal zirconia polycrystal (TZP). Y-TZP presents various interesting characteristics, such as low porosity, high density and high bending and compression strength, proving that it is suitable for biomedical application. UV-treated zirconia surfaces exhibited an enhanced osteoblast response, which was characterized by an accelerated and augmented cell attachment, accelerated cell spread and cytoskeletal development with increased proliferation. The purpose of this paper is to identify which method of treatment of zirconia material implant & ultraviolet stimulation effect for bone healing is the most effective and efficient based on literature review. Bone grafts are available in a variety of substances. These bone substitutes can be biological (natural) or synthetic. Re-absorption is also essential for bone growth. Specific cells continuously break down bones and rebuild them. Substitutes that break down too quickly are not suitable for bone grafts, as they do not allow enough time for the new bone to grow. From our literature review, Zirconia is one of the biomaterials that have a bright future because of its high mechanical strength and fracture toughness. Zirconia ceramics have several advantages over other ceramic materials due to the transformation toughening mechanisms operating in their microstructure that can be expressed in components made out of them. UV treatment substantially enhances the osteogenesis process, resulting in a greater amount of peri-implant bone, as well as an increased strength of bone-zirconia integration.
