Abstract: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(P<0.01).The AL value reduced from（3.56±1.17） mm to （3.34±1.03） mm after 3 months and there was statistical difference(P<0.05). 6 months after fixation,the  PD value reduced to （3.21±0.25） mm,and there was significant difference compared with  before  fixation(P<0.01). The   AL value reduced to （3.36±1.31） mm,and  there was significant difference compared with  before  fixation(P<0.05);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.
