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 biological seal between the oral cavity and the alveolus.
介绍了多孔根状氧化铝牙科植入物在动物体内的制造、表征及临床结果。所有植入物均在不到六个月内失败，原因是植入物牙冠和颈部存在微孔，这阻碍了口腔与牙槽之间有效生物密封的建立。
