摘要：

目的    探讨慢性牙周炎三壁骨下袋植骨术中生物膜应用与否对牙周病治疗效果的影响。方法    选择2012年1月至2013年12月在佛山市禅城区向阳医院口腔科就诊的三壁骨下袋且牙周袋探诊深度（PD）≥ 5 mm、骨吸收区角度≤60°的慢性牙周炎患者30例，随机分成两组。盖膜组（15例）：在行牙周植骨术同时覆盖Bio-Gide生物膜；非盖膜组（15例）：仅行牙周植骨术不覆盖Bio-Gide生物膜。术后6、12个月回访，检查PD、临床附着丧失（CAL）、龈沟出血指数（SBI）、牙龈退缩（GR）等牙周观察指标的变化；通过X线检查测量植骨区骨密度和植骨区新生骨高度，比较两组骨缺损修复情况。结果    两组术后6、12个月的PD、CAL、SBI和GR均较术前明显改善，差异均有统计学意义（均P < 0.05）；但两组之间差异无统计学意义（P > 0.05）。两组术后6、12个月的植骨区骨密度及新生骨高度均有明显升高，但两组之间差异无统计学意义（P > 0.05）。结论    对慢性牙周炎三壁骨下袋的患牙施行不覆盖生物膜的牙周植骨术，疗效确切，并且可简化术式，减少手术创伤，降低手术费用。

Abstract:

Objective    To study the effect of biofilm on treatment result of three wall intrabony graft surgery for chronic periodontitis. Methods    Select 30 cases of chronic periodontitis with the three wall intrabony and probing depth（PD）≥ 5 mm，resorption area ≤ 60° angle from January 2012 to December 2013 in Foshan Xiangyang Hospital who were randomly divided into two groups. The cover film group：15 cases，with periodontal bone grafting while covering Bio-Gide biofilms；non-membrane cap group：15 cases，only with the line of periodontal bone graft and without Bio-Gide biofilms. Six and 12 months after the visit，changes in inspection probing pocket depth（PD），clinical attachment loss（CAL），sulcus bleeding index（SBI），gingival recession（GR）and other periodontal indicators were observed； bone mineral density and bone area district new bone height were measured by X-ray for statistical analysis；compare bone defects of the two groups. Results      In the two groups PD，CAL，SBI and GR had significant improvement at 6 and 12 months compared with preoperative ones，the differences being statistically significant（P < 0.05），but the difference between the two groups was not statistically significant（P > 0.05）. Postoperative bone mineral density and area of new bone height at 6 and 12 months were significantly higher, but the difference between the two groups was not statistically significant（P > 0.05）. Conclusion    For chronic periodontal disease three wall intrabony teeth， periodontal bone graft without biofilm has good effect，and can simplify the procedure，reduce surgical trauma and lower operation costs.
