J Periodontol:不同牙龈形态对游离龈移植体积稳定性的影响:一项6个月的临床对照研究

2019-01-22 lishiting MedSci原创

这篇研究的目的是为了评估牙齿邻接区域的近远中游离龈移植(FGG)的牙龈形态对其术后6个月收缩的影响。

这篇研究的目的是为了评估牙齿邻接区域的近远中游离龈移植(FGG)的牙龈形态对其术后6个月收缩的影响。

研究纳入了在下颌切牙周围具有异常角化龈宽度(KGW)的31名患者。采用探诊透明度法和角化龈厚度检测法评估牙齿近远中的牙龈形态;研究组分为厚和薄形态。分别记录术前和术后6个月的菌斑指数(PI), 牙龈指数(GI), 探诊深度(PD), 临床附着水平(CAL)和退缩高度(GRH), 退缩宽度(GRW)和KGW测量结果。在手术中记录移植物的垂直距离(VDG)和水平距离(HDG)、承受区的水平宽度(RAHW)和垂直宽度(RAVW)。通过java类的分析程序计算退缩率。

结果显示,各组临床和手术测量结果之间没有显著性差异。与术前相比,术后6个月牙齿2侧邻接区域的平均KGW值增加,但是各组在第6个月没有明显不同。厚形态组在术后6个月的GRH值明显降低。薄和厚形态组的退缩率分别为23.14 ± 12.21%和17.76 ± 11.05%。组间未见显著性差异(p = 0.210)。

结论:邻接牙齿牙龈的形态对于FGG术后6个月的退缩率具有相似的影响。临牙牙龈的较薄形态看起来更有利于牙根覆盖。
