摘　　要：目的:评价应用新型Quartz SplintTM高强度石英纤维夹板固定前牙的临床效果,为治疗牙周炎导致的牙齿松动提供临床依据。方法:应用Quartz SplintTM高强度石英纤维夹板对32例慢性牙周炎患者Ⅱ°、Ⅲ°松动前牙进行固定,观察固定前和固定后3、6个月牙周探诊深度(PD)、牙周附着水平(AL)和牙槽骨高度的变化。结果:松牙固定后3个月,患牙的PD由(4.39±1.26)mm减至(3.16±0.37)mm,差异有统计学意义(P<0.01);AL由(3.56±1.17)mm减至(3.34±1.03)mm,差异有统计学意义(P<0.05)。固定后6个月PD为(3.21±0.25)mm,与固定前比较差异有统计学意义(P<0.01);AL为(3.36±1.31)mm,与固定前比较差异有统计学意义(P<0.05),与固定3个月比较差异无统计学意义。X线显示所有患牙均无进一步的骨吸收,临床状况改善明显。结论:应用Quartz SplintTM高强度石英纤维夹板固定前牙可获得较满意的临床效果。Objective To evaluate the clinical effect of Quartz SplintTM high strength quartz fibre splint in fixing mobile anterior teeth and to provide the clinical evidence for the treatment of teeth moving periodontitis patients.Methods The Ⅱ degree and Ⅲ degree mobile anterior teeth of thirty two cases of chronic periodontitis patients were fixed by Quartz SplintTM high strength quartz fibre splint.The clinic status such as probing depth（PD）,attachment level（AL） and radiograph were measured before fixation and 3,6 months after fixation.Results The value of PD reduced from（4.39±1.26） mm to（3.16±0.37） mm after 3 months and there was statistical difference（P0.01）.The AL value reduced from（3.56±1.17） mm to（3.34±1.03） mm after 3 months and there was statistical difference（P0.05）.6 months after fixation,the PD value reduced to（3.21±0.25） mm,and there was significant difference compared with before fixation（P0.01）.The AL value reduced to（3.36±1.31） mm,and there was significant difference compared with before fixation（P0.05）;and there was no statistical difference compared with 3 months after fixation.Meanwhile,advanced bone loss was not found.Conclusion The Quartz SplintTM high strength quartz fibre splint can get satisfactory clinical effect in fixing mobile anterior teeth.
