An Evaluation of Porous Alumina Ceramic Dental Implants

Abstract
The fabrication, characterization, and clinical results of porous rooted alumina dental implants in animals are presented. Failures of all implants occurred in less than six months and were attributed to the presence of microporosity on the crown and cervical portion of the implant which prevented the establishment of an effective bialogical seal between the oral cavity and the alveolus.
