摘　　要：目的:评价应用新型Quartz Splint TM高强度石英纤维夹板进行前牙正畸保持的临床效果,为选择适当正畸保持方法提供依据。方法:选择62例完成正畸常规治疗后需局部加强保持者,将患者按照随访时间分为3个月组、6个月组和12个月组。应用Quartz Splint TM高强度石英纤维夹板对前牙进行固定。目视和器械检查每个组保持器有无脱落位点,牙齿间隙及扭转错位有无复发同时检查保持器区域内牙周健康状况,即检查探诊深度(PD)、出血指数(BI)和菌斑指数(PLI),评价Quartz Splint TM高强度石英纤维夹板在前牙正畸保持中的应用效果。结果:62例患者中,60例患者Quartz Splint TM高强度石英纤维夹板均固位良好,无松脱及断裂且间隙及扭转,均未复发。仅有2例纤维夹板分别在第6个月和第12个月个别位点脱落但无断裂。随访期内Quartz Splint TM高强度石英纤维夹板总完好率为96.77%,且患者牙周状况健康。结论:应用Quartz Splint TM高强度石英纤维夹板对前牙区散在间隙或者扭转牙正畸后固定保持可获得稳定的临床效果。Objective To evaluate the clinical effect of the application of the new Quartz Splint^TMhigh strength silica fiber splint in keeping the orthodontic teeth,and to provide the basis for choosing appropriate orthodontic retainer.Methods A total of 62 patients needing local strengthening retainer after completed orthodontic treatment were selected.The patients were divided 3-month,6-month and 12-month groups according to the follow-up time.Quartz Splint^TMhigh strength silica fiber splint was used to fox the labial teeth.Visual and instrument examination were used to check wether there were off-sites of retainers in various groups,teeth gap and the presence of recurrent dislocation;the periodontal health status was observed including probing depth（PD）,bleeding index（BI）,and plaque index（PLI）.Results 60 patients using Quartz Splint^TMhigh strength silica fiber splint were stable without frature while the periodontal tissue revealed no significant changes in all 62 patients.Only 2cases of Quartz Splint^TM high strength silica fiber splint in 6 months and 12 months respectively had individual off-sites without breaking.During 12-month follow-up period,the total intact rate of Quartz Splint^TM high strength silica fiber splint was 96.77%,and the patients had healthy periodontal conditions.Conclusion The stable clinical effect can be obtained by the application of Quartz Splint^TM high strength silica fiber splint for scattered clearance of the front teeth area or rotated teeth after orthodontic.
