Determination of Young's Modulus of Hydroxyapatite Doped with Magnesium by Vibration Method

摘要

Implants and bone reconstruction have known a great development recently. Synthesized bone tissues must have mechanical, physiological and biological properties closer to natural bone, as much as possible. Bioceramics are materials which fulfill these conditions, being biocompatible with mechanical strength similar to bone. One material widely used is hydroxyapatite. Hydroxyapatite is slightly different from bone tissue and it forms the mineral part of bone tissue. In order to improve mechanical properties and biological compatibility hydroxyapatite is doped with different compounds, mainly chemical elements. Magnesium, a chemical element present in human bone structure is one of these compounds.
