Homologous freeze dried dura mater (FDDM) was used as a graft material in the correction of inadequate zones of attached gingiva. Eleven patients having a mean preoperative width of attached gingiva of 0.31 mm with a range of 0 to 1 mm were used in this study. A total of 17 grafts were implanted at 42 tooth sites, all on the buccal side of the mandibular arch. Clinical observations were conducted over a 3-month postoperative period. The parameters examined pre- and postoperatively were the width of the attached gingiva, the crevice depth and the width of the homologous FDDM implanted. Postoperatively, the mean width of the attached gingiva was 3.65 mm with a range of 2 to 6 mm. This finding was statistically significant (P less than 0.001). The crevice depths did not vary significantly and the implanted FDDM evidenced a mean shrinkage of 46.7%. Within its temporal limits, the present study has shown that homologous FDDM can be used effectively as a free graft in mucogingival surgery to correct inadequate zones of attached gingiva.
同种异体冻干硬脑膜（FDDM）被用作移植材料，用于矫正附着龈不足区域。本研究纳入了11例患者，术前附着龈平均宽度为0.31mm，范围为0至1mm。共在42个牙位植入了17块移植物，均位于下颌牙弓的颊侧。术后3个月进行临床观察。术前和术后检查的参数包括附着龈宽度、龈沟深度和植入的同种异体FDDM的宽度。术后，附着龈平均宽度为3.65mm，范围为2至6mm。这一结果具有统计学意义（P小于0.001）。龈沟深度无显著变化，植入的FDDM平均收缩率为46.7%。在其时间限制范围内，本研究表明同种异体FDDM可有效地作为游离移植物用于膜龈手术，以矫正附着龈不足区域。
