摘　　要：目的:比较Filtek Z350XT纳米充填树脂和流动树脂,Tetric-N纳米瓷化充填树脂和流动树脂4种材料在粘接无托槽隐形矫治器附件时的操作时间和临床稳定性,为临床选择合适附件粘接材料提供依据。方法:将采用无托槽隐形矫治的60例错牙合畸形患者随机分为4组,每组15人。A组采用3M Adper SingleBond2粘接剂和Filtek Z350XT纳米充填树脂粘接附件,B组采用3M Adper SingleBond2粘接剂和Filtek Z350XT纳米流动树脂,C组采用Tetric N-bond粘接剂和Tetric N-cerum纳米瓷化充填树脂,D组采用Tetric N-bond粘接剂和Tetric N-flow纳米瓷化流动树脂。记录粘接每组附件所需的操作时间,评价粘接后、粘接后1个月、粘接后6个月、粘接后9个月和12个月后4组附件的脱落情况。结果:应用流动树脂粘结附件的操作时间较充填树脂短(P<0.01);使用同种树脂粘接优化附件和传统附件在脱落率方面无明显差异;4种材料的脱落率在粘接时、粘接后1个月、粘接后6个月时均无统计学差异,但在粘接后9个月和粘接后12个月,流动树脂相比充填树脂脱落率较高(P<0.01)。结论:流动树脂临床操作时间短,4种粘接材料在治疗初期的稳定性均达到满意的效果,但充填树脂在治疗后期的稳定性更好。Objective:To evaluate the operation time and clinical bonding failure of four types of bonding materials(Filtek Z350 XT nano filling composite resin,Filtek Z350 XT nano flowable composite resin,Tetric N-flow composite resin,Tetric N-cerum filling composite resin)in bonding attachment of removable thermoplastic appliance.Methods:Sixty malocclusion patients using removable thermoplastic appliances were randomly divided into four groups.3M Z350 nano filling composite resin and Z350 nano flowable composite resin were used in group A and B,respectively.Tetric N-flow composite resin and Tetric N-cerum filling composite resin were bonded in group C and D,respectively.The operation time of each group was recorded.Failure rates of adhesion were evaluated at the end of adhesion,and 1 month,6 months,9 months,and 12 months after adhesion.Results:The operation time of flow composite resin group was shorter than that of filling composite resin group(P<0.01).The adhesion failure rates were not significant different among four groups in the first 6 months.Significant difference was found between flow composite resin group and filling composite resin group after 9 and 12 months(P<0.01).However,no difference was found between optimized attachment and traditional attachment.Conclusion:The attachment stability of four types of materials could achieve satisfactory effect in the first 6 months.After 9 months,filling composite resin was more stable than nano flowable composite resin.However,the operation time of nano flowable composite resin was more efficient.
