摘要
目的研究影响无托槽隐形矫治器附件脱落的相关因素。方法对51例无托槽隐形矫治患者的1091个附件，进行1年的追踪观察。记录附件脱落情况，分析探讨导致附件脱落的相关因素。运用单因素及多因素（Logistic回归）研究每个因素与附件脱落的关系。结果单因素分析显示磨牙附件（脱落率-22．4％，p=0．006）、传统附件（脱落率-20．4％，P=0．000）、不配戴矫治器进食（脱落率-18．3％，P=0．001）、每天摘戴次数≥5次（脱落率：20．2％，p=0．014）者附件脱落率增加。多因素分析表明：附件形态（P=0．001，OR=1．782）、每天摘戴矫治器的次数（P=0．031，OR=1．440）、是否配戴矫治器进食（P=0．001，OR—O．451）均是影响附件脱落的独立因素。配戴矫治器进食是附件脱落的抑制因素。结论传统附件和矫治器每天摘戴次数≥5次者可能导致附件脱落率增高，配戴矫治器进食能减少附件脱落的可能性。
Objective The purpose of this study was to analyze the influencing factors of attachment loss in clear aligner treatment. Methods A clinical observation was performed on 1-year follow up clinical data of 51 patients who had clear aligner treatment with 1091 attachments. The status of attachment loss was recorded. Different factors affecting attachment loss were analyzed. Associations between these variables and attachment loss were analyzed using univariate analyses and multivariable logistic regression. Results Univariate analyses revealed that the factors affecting the attachment loss were molar attachment（losing rate= 22. 4%, P = 0. 006）, traditional attachment （losing rate=20.4Y00,P=0. 000）,having food without appliance（losing rate=18.3~,P=0. 001） and aligner removal frequency more than or equal to five times a day（losing rate = 20. 2%, P=0. 014）. However, upper or lower teeth, first bonding or second bonding, choice of food and removal method of clear aligner had no impacts on attachment loss according to univariate analysis. The geometry of attachment （P=0. 001,OR=1. 782）,aligner removal frequency （P=0. 031,OR=1. 440） and presence or absence of appliance when having food （P=0. 001, OR=0. 451） were proved to be significant independent predictors of attachment loss with muhivariable logistic regression analysis. Having food with appliance may be a disincentive of attachment loss. Conclusions The traditional attachment and aligner removal frequency （ more than or equal to five times a day） may lead to attachment loss. Having food with appliance may prevent attachment loss.
