摘　　要：目的:对比分析MillerⅠ、Ⅱ类牙龈退缩治疗中隧道技术联合脱细胞真皮基质补片与冠向复位瓣术联合结缔组织移植治疗的应用效果。方法:选取2018年4月-2019年4月本院60例MillerⅠ、Ⅱ类牙龈退缩手术治疗患者,随机分两组,每组30例。对照组使用冠向复位瓣术联合结缔组织移植治疗,研究组使用隧道技术联合脱细胞真皮基质补片治疗。比较两组治疗前后患牙根面覆盖率、临床指标、美学及疼痛评分。结果:两组治疗前患牙根面覆盖率、疼痛评分比较,差异均无统计学意义(P>0.05);研究组治疗后各指标均优于对照组(P<0.05)。两组治疗前后牙周袋探针深度、牙龈退缩深度、临床附着水平、牙龈退缩宽度、角化龈宽度、牙龈厚度比较,差异均无统计学意义(P>0.05)。两组治疗前红色美学评分、白色美学评分比较,差异均无统计学意义(P>0.05);研究组治疗后各评分均高于对照组(P<0.05)。结论:MillerⅠ、Ⅱ类牙龈退缩患者治疗中隧道技术联合脱细胞真皮基质补片的应用效能够达到与冠向复位瓣术联合结缔组织移植相近的疗效,并有效缓解患者痛苦,提升美学效果。Objective:To compare and analyze the application effect of tunneling technique combined with acellular dermal matrix patch and coronal reduction flap combined with connective tissue transplantation in the treatment of MillerⅠandⅡgingival recession.Method:A total of 60 type gingival recession patients in our hospital from April 2018 to April 2019 were randomly divided into two groups,30 cases in each group.The control group was treated with coronal reduction flap combined with connective tissue transplantation,and the study group was treated with tunneling technique combined with acellular dermal matrix patch.The root surface coverage,clinical indexes,aesthetic scores,and pain scores were compared between two groups before and after treatment.Result:There were no significant differences in the root surface coverage and pain scores between two groups before treatment(P>0.05);after treatment,the study group were superior to the control group(P<0.05).There were no significant differences in the depth of periodontal pocket probe,gingival recession depth,clinical attachment level,gingival recession width,keratinized gingival width and gingival thickness between two groups before and after treatment(P>0.05).Before treatment,there were no significant differences in the red aesthetic score and white aesthetic score between two groups(P>0.05);after treatment,the study group were higher than those of the control group(P<0.05).Conclusion:The application effect of tunneling technique combined with acellular dermal matrix patch in the treatment of patients with MillerⅠandⅡgingival recession can achieve a similar effect to that of coronal reduction flap combined with connective tissue transplantation,and effectively relieve the pain of patients and enhance the aesthetic effect.
