J Periodontol: 两种种植体黏膜增厚术式的比较

2018-06-04 MedSci MedSci原创

目前的证据支持足够的种植体周围粘膜厚度(PMT)有利于边缘骨水平稳定和美学效果。传统认为上皮下结缔组织移植(sCTG)是种植体周围粘膜增厚的金标准,但无细胞真皮基质(ADM)可能是一种有效的替代方法。该随机临床试验的主要目的是确定ADM与自体sCTG增加PMT的临床疗效的比较。

目前的证据支持足够的种植体周围粘膜厚度(PMT)有利于边缘骨水平稳定和美学效果。传统认为上皮下结缔组织移植(sCTG)是种植体周围粘膜增厚的金标准,但无细胞真皮基质(ADM)可能是一种有效的替代方法。该随机临床试验的主要目的是确定ADM与自体sCTG增加PMT的临床疗效的比较。

实验招募植入种植体时需要增厚周围粘膜的患者。参与者被随机分配到对照组(sCTG)或实验组(ADM)。本研究主要是评估实验初与16周后PMT的变化。同时记录角化粘膜宽度(KMW)的变化,改良伤口愈合指数(MWHI)变化和患者自己测量的结果值(PROM)。

结果:实验最终纳入20名参与者。对于所有参数,组间初始值无统计学差异。在距离预期粘膜边缘1mm,3mm和5mm的PMT中,sCTG组的PMT增加为0.44±2.04mm,1.20±1.48mm和1.20±0.89mm,ADM组为0.05±1.57mm,0.85±1.29mm和1.45±1.17 mm。组间PMT,KMW和MWHI变化没有显着的统计学差异。 sCTG组患者2周和4周时明显感觉不适。

在植入种植体时,ADM与sCTG的粘膜增厚作用类似。
