Synthetic Hydroxyapatite (HAp) has been shown to be one of a select few materials which are both biocompatible and bioactive. HAp has an elastic moduli higher than that of cortical bone, however, due to unpredictable fatigue properties and design limitations, porous HAp cannot be used in a bulk form as a load bearing implant. These problems can be overcome by using HAp as a coating material on metallic and ceramic substrates. The use of a bioactive coating has been widely reported employing… CONTINUE READING
