A new technique for cranioplasty with L-shaped titanium

OBJECTIVE The use of hydroxyapatite-based ceramics for cranioplasties has recently increased in Japan,because of the good cosmetic outcomes,biocompatibility,strength,osteoconductive properties,and lack of risk of disease transmission associated with these materials.However,miniplate fixation has not been possible for ceramic implants.We describe a new technique for miniplate fixation Biocompatible Materials Scholars@DukeBiocompatible Materials Subject Areas on Research Biological Evaluation of Pliable Polymer-Ceramic CompositesShiny Velayudhan,Girish Menon,Ramesh Parameswaran Biological Evaluation of Pliable Polymer-Ceramic Composites - Bioactive,Hydroxyapatite Filled Ethylene Vinyl Acetate Co-polymer for Cranioplasty Implantation Studies in Rabbits.Paperback.Sprache Englisch.(Buch (kartoniert)) - portofrei bei eBook.de
