1、纤维树脂夹板与烤瓷冠桥固定夹板治疗中重度牙周病松动牙的疗效比较【摘耍】目的：探讨纤维树脂夹板与烤瓷冠桥固定夹板治疗中重度牙周病松动牙的疗效差异。方法：选取本院口腔科中重度牙周病松动牙患者30例，随机数字表法分为两组，观察组患者采用纤维树脂夹板治疗；对照组患者采用烤瓷冠桥固定夹板治疗。比较两组患者治疗0、3、6个月菌斑指数(PLI)、出血指数(BI)、牙周袋探针深度(PD)、临床附着丧失(CAL)与牙齿松动度(TM)的差异。结果：治疗0、3个月，两组比较差异均无统计学意义(P>0・05)；治疗6个月，观察组PLI明显低于对照组(P〈0.05),对照组PLI、BI明显高于治疗0、3个月(P〈0
2、・05)；治疗3、6个月，观察组卩D、CAL值均明显低于对照组与同组治疗0个月(P〈0.05)o全部患者牙周固定状态下患牙与牙周固定夹板整体均无松动。结论：纤维树脂夹板与烤瓷冠桥固定夹板均能有效改善中重度牙周病松动牙的牙齿松动度，但纤维树脂夹板对菌斑控制与PD、CAL值的改善程度更佳，值得临床推广应用。【关键词】纤维树脂夹板；烤瓷冠桥固定夹板；牙周病；松动牙[Abstract】Objective：TostudythecurativeeffectdifferenceoffiberresinsplintandPFMcrownandbridgefixedsplintformoderate-sev
