The aim of this study was to compare and evaluate the clinical failure rates of the chemically cured composite bonding resin Maximum Cure (MC) and the flowable light-cured resin Filtek Flow (FF) when used in an indirect bonding technique. A total of 112 consecutive patients satisfying the selection criteria were assigned to alternating groups in a split-mouth study design. In Group 1, the maxillary right and mandibular left quadrants were indirectly bonded using MC adhesive, whereas the contralateral quadrants were bonded using FF adhesive. In Group 2, the sides bonded were opposite to those in Group 1. One patient was lost from group 1, so the adjacent patient from group 2 was excluded. Over a six-month observation period, all loose brackets were recorded and the data compared with a Wilcoxon signed ranks test. Of the 2468 brackets placed, 36 with the MC adhesive came loose (2.9% failure rate) compared with 30 in the FF group (2.4% failure rate, P = .95). In the maxillary arch, 12 brackets from the MC quadrants came loose vs 24 in the FF (P = .02). In the mandibular arch, 24 brackets from the MC quadrants came loose during the six-month observation period compared with six from the FF quadrants (P = .03). These results suggest that both adhesives examined in this study (MC and FF) were suitable for the indirect bonding of brackets. The failure rates were low for both adhesives, so either could be recommended for clinical use, the choice being dictated more by operator preference.
本研究的目的是比较和评估化学固化复合粘结树脂Maximum Cure（MC）和可流动光固化树脂Filtek Flow（FF）在间接粘结技术中使用时的临床失败率。在一项分口研究设计中，共有112名符合选择标准的连续患者被分配到交替组。在第1组中，右上颌和左下颌象限使用MC粘合剂进行间接粘结，而对侧象限使用FF粘合剂进行粘结。在第2组中，粘结的侧与第1组相反。第1组有1名患者失访，因此第2组的相邻患者被排除。在六个月的观察期内，记录所有松动的托槽，并使用Wilcoxon符号秩检验比较数据。在放置的2468个托槽中，使用MC粘合剂的有36个松动（失败率2.9%），而FF组为30个（失败率2.4%，P = 0.95）。在上颌弓中，MC象限有12个托槽松动，而FF象限有24个（P = 0.02）。在下颌弓中，在六个月的观察期内，MC象限有24个托槽松动，而FF象限有6个（P = 0.03）。这些结果表明，本研究中检测的两种粘合剂（MC和FF）都适用于托槽的间接粘结。两种粘合剂的失败率都很低，因此两种都可推荐用于临床，选择更多地取决于操作者的偏好。
