摘　　要：目的比较一种新型异种胶原基质(XCM)与游离龈(FGG)在增宽种植体周角化黏膜的临床疗效。方法选取种植体颊侧角化黏膜宽度<2mm患者74例,按就诊顺序分为两组,其中FGG组37例,XCM组37例。分别行FGG或XCM移植,比较两组术后即刻及术后1、3.6、12个月种植体颊侧KTW,手术后各时间点组织收缩率以及两组手术所用时间。结果XCM组和FGG组在术后即刻角化黏膜宽度分别为(10.08±1.90)mm和(9.79±1.49)mm;XCM组与FGG组在术后1、3、6、12个月各时间点,种植体颊侧KTW均较基线显著增宽(P<0.05)。移植组织在术后均有不同程度收缩,术后3月内移植组织收缩最快。两组间术后3、6、12个月角化黏膜收缩率比较,差异均有统计学意义(P<0.05)。XCM组的手术时间明显少于FCG组(P<0.01)。结论XCM与FCG在术后均能增宽种植区域KTW;使用XCM进行角化黏膜增量手术能简化手术操作步骤,操作时间明显减少。虽然一年内XCM组织收缩率大于FCG,但角化黏膜宽度仍>2mm。Objective To compare the clinical efficacy of new heterogeneous collagen matrix(XCM)and free gingival graft(FGG)in widening the keratinized tissue in the implant area.Methods Seventy-four patients with implant buccal keratinized tissue width(KTW)<2 mm were selected.The patients were divided into a FGG group and a XCM group according to the order of visit,37 in each group.FGG or XCM transplantation was performed,respectively.The buccal KTW of the implants immediately after surgery and after 1 month,3,6,and 12 months after surgery were compared between the two groups.The operation time and tissue shrinkage rate at each time point after surgery were also compared between the two groups.Results The KTW immediately after surgery was(10.08±1.90)mm in the XCM group and(9.79±1.49)mm in the FGG group.At each time point of 1 month,3,6,and 12 months after surgery,the KTW on the buccal side of the implant was significantly wider than the baseline in both groups(P<0.05).The transplanted tissue shrank to varying degrees after surgery,and the transplanted tissue shrank fastest within 3 months after surgery.Among the 3rd month,the 6th month,and the 12th month,the tissue contrast was significant difference between the two groups(P<0.05)at each time point.The XCM group had significantly shorter operation time than the FGG group did(P<0.01).Conclusions Both XCM and FGG are suitable for the regeneration of the peri-implant keratinized mucosa.With the XCM,tissue harvesting procedures are effective,and surgery time can be reduced.Although the contraction rate of XCM was higher than FGG within one year,the width of keratinized mucosa is still sufficient.
