本文是对恒河猴裸露牙骨质的无髓牙根面上附丽装置能否再生的研究。附丽装置是指牙槽骨、牙骨质及牙周韧带而言。这些组织为了牙齿能抵抗功能压力,而提供必需的支持力。研究分三步进行:第一步是预备根管,在四个上中切牙中,一个保留活髓作对照,另一个牙则去除牙髓,髓腔任其敞开,另外两个切牙的根管则进行机械处理、扩大,其中一个牙封樟脑酚纸尖,直到观察期末,其中另一牙用牙胶尖充填根管。术前、术后都 This article is about the Rhesus Monkey naked cementless root surface with the device attached to the proliferation of renewable research. Attachment means that the alveolar bone, cementum and periodontal ligament purposes. These organizations provide the necessary support for teeth to withstand functional stress. The study was divided into three steps: The first step was to prepare the root canal. One of the four upper incisors kept the vital pulp as a control, while the other one removed the pulp, leaving the open cavity. The other two incisors The root canal was mechanically treated and expanded, one of which was sealed with camphor phenol paper until the end of the observation period, of which the other tooth was filled with gutta-percha tip. Preoperative and postoperative
