A STUDY HAS BEEN CARRIED OUT ON THE STRUCTURE AND SURFACE TEXTure of a new dental implant material composed of vitreous carbon balloons (3 wt % or 6 wt %) and poly(methyl methacrylate). Tooth replica implants using this material had been successfully placed in baboons, and histologic study revealed normal alveolar bone and a peri-implant membrane with the connective tissue fibers oriented in a horizontal direction. Square wafers (10 mm X 10 mm X 1 mm) were studied, with the surface sandblasted in one-half of the specimens. Light microscopy revealed that in the 3% carbon specimens, the vitreous carbon micro-balloons were evenly spaced and often appeared to be fragmented within their spaces. S.E.M. studies revealed a finely porous surface with numerous large craters. Microballoons were often seen within the craters in the nonsandblasted specimens.
一项针对由玻璃碳球（3重量%或6重量%）和聚甲基丙烯酸甲酯组成的新型牙科植入材料的结构和表面纹理进行了研究。使用这种材料的牙齿复制植入物已成功植入狒狒体内，组织学研究显示牙槽骨正常，植入物周围膜的结缔组织纤维呈水平方向排列。研究了方形薄片（10毫米×10毫米×1毫米），其中一半标本的表面进行了喷砂处理。光学显微镜显示，在含3%碳的标本中，玻璃碳微球分布均匀，且在其空间内常出现破碎现象。扫描电子显微镜研究显示表面有精细的孔隙，有许多大坑。在未喷砂处理的标本的坑内常可见到微球。
