背景：本研究的目的是比较隧道技术使用胶原基质（CM）和结缔组织移植（CTG）在短时间内治疗多种Miller I类和II类衰退的疗效。方法：28例患者入组研究。对照组采用CTGs隧道技术治疗，试验组采用异种CM隧道技术治疗。在基线、3个月和6个月后获得临床记录。术后3个月和6个月评估平均衰退覆盖率（ARC）和完全衰退覆盖率（CRC）的百分比。结果：与基线测量值相比，两组衰退参数均有显著下降。6个月后，试验组的平均衰退深度（0.21比0.39 mm）和衰退面积（0.31比0.53 mm(2)）显著高于对照组（P < 0.05）。两组平均角化组织宽度（KTW）以相似的速率增加（对照组和试验组分别为1.0和0.8 mm）。6个月后，对照组的ARC为95%，试验组为91% (P < 0.05)；对照组的CRC为71.4%(10/14)，试验组的CRC为14.3% (2/14)（P < 0.05）。结论：异种CM联合隧道技术可获得满意的ARC， KTW的增加与CTG相似，但不满意的CRC发生率较低。
Background: The aim of this study is to compare efficacy of the tunnel technique for root coverage using collagen matrix (CM) versus connective tissue graft (CTG) for treatment of multiple recessions of Miller Classes I and II over a short period of time.Methods: Twenty-eight patients were enrolled in the study. Patients in the control group were treated with the tunnel technique using CTGs, whereas patients in the test group were treated with the tunnel technique using xenogeneic CM. Clinical recordings were obtained at baseline and after 3 and 6 months. Percentages of average recession coverage (ARC) and complete recession coverage (CRC) were evaluated 3 and 6 months after surgery.Results: Significant decreases were recorded in both groups of recession parameters compared with baseline measurements. Mean recession depth (0.21 versus 0.39 mm) and recession area (0.31 versus 0.53 mm(2)) after 6 months were significantly higher in the test group (P < 0.05). Mean keratinized tissue width (KTW) increased at a similar rate in both groups (1.0 versus 0.8 mm for control and test groups, respectively). ARC after 6 months was 95% in the control group and 91% in the test group (P < 0.05), and CRC was 71.4% (10/14) in the control group and 14.3% (2/14) in the test group (P < 0.05).Conclusion: Xenogeneic CM combined with tunnel technique leads to satisfactory ARC and increase in KTW similar to CTG, but yields lower unsatisfactory CRC.
