Techniques for new attachment using the principle of guided tissue regeneration with barrier membranes have become accepted as a method for treating teeth with severe osseous defects and furcation involvement. After an evaluation of existing membranes and techniques, a procedure was developed using an expanded polytetrafluoroethylene soft tissue patch, 1 mm thick (W. L. Gore and Assoc., Flagstaff, AZ), in conjunction with an alloplast hydroxylapatite bone substitute (HA-500, 40-60 mesh) (Orthomatrix, Minneapolis, MN), to maintain a space for the maturation of the blood clot. An in vitro study of microbial adherence to the soft tissue patch indicated that the number of attached Streptococcus sanguis (gordonii) G9B, and Actinomyces viscosus T14 (V) cells was significantly lower (P < .005 and P < .025, respectively) than the number of bacteria that attached to Gore-Tex Periodontal Material. Two case reports are presented to demonstrate the successful use of the soft tissue patch augmented with hydroxylapatite in patients exhibiting furcation involvement and severe vertical osseous defects.
利用屏障膜引导组织再生原理进行新附着的技术，已被公认为是治疗伴有严重骨缺损和根分叉病变牙齿的一种方法。在对现有膜材料和技术进行评估后，开发了一种手术方法，即使用1毫米厚的膨体聚四氟乙烯软组织贴片（W.L. Gore及联营公司，弗拉格斯塔夫，亚利桑那州），结合一种异体羟基磷灰石骨替代物（HA - 500，40 - 60目）（Orthomatrix，明尼阿波利斯，明尼苏达州），以维持血凝块成熟的空间。一项关于微生物附着于软组织贴片的体外研究表明，附着的血链球菌（戈登氏菌）G9B和粘性放线菌T14（V）细胞数量显著低于附着于戈尔特斯牙周材料的细菌数量（分别为P < 0.005和P < 0.025）。现展示两例病例报告，以证明在表现出根分叉病变和严重垂直骨缺损的患者中成功使用了羟基磷灰石增强的软组织贴片。
