Australia has been using hydroxyapatite/coral for chin and jaw implants for 15 years? Coral is suppose to have properties that are alike to human bone? Infection rate is nill? Why aren't doctors in the US/other countries jumping onto coral instead of using silicone etc?Any doctors in the US/UK using coral for chin/jaw implants?http://www.dermnetnz.org/procedures/hydroxyapatite.html (http://bmendelson.com.au/)
