The effects of sintering behavior of zirconiadoped hydroxyapatite for clinical applications

Hydroxyapatite is one of the most potential bioceramic to be applied into the medical and dental field due to its biocompatibility with human hard tissue. However, its properties are still behind those of hard tissues and further studies need to be done to improve its mechanical properties. In the c...
