Clear aligner treatment is an orthodontic treatment that is custom-made with 3D printers without the use of conventional metal or porcelain wires and brackets. It is a modern orthodontic method used to correct tooth positions that need to be corrected aesthetically and functionally. Aim This study aimed to compare the discolouration of teeth and clear aligners after 15 days of full-time use of clear aligners. Materials and methods The 20 patients in the study group had used clear aligners for 45 days, including three different clear aligners for 15 days. In addition, 20 patients were included as a control group to measure the difference in tooth discolouration. Retaining attachments using G-Aenial (GC Corp, Tokyo, Japan) and 3M ESPE (St. Paul, MN, USA) flowable composites were placed crosswise to each patient in the distal regions of all lateral and canine teeth. The performance of three aligner plates (Zendura Flex (Bay Materials LLC, Fremont, CA, USA); Duran (ScheuDental GmbH, Iserlohn, Germany); and Taglus (Laxmi Dental Export Pvt. Ltd, Mumbai, India)), two fluid composite attachments, and two clear aligner cleaners regarding discoloration were tested. Each aligner was used for 15 days, and then the patient was moved to the next aligner. Colour change on the aligners and the patients' teeth were assessed from the canine to the middle third and mid-plane of the canine tooth using a VITA Easyshade V spectrophotometer (Bad Säckingen, Germany). An aligner cleaner was used immediately after the patients used their clear aligners, and then the measurements of the aligner color values were completed. The 120 aligners obtained were divided into two groups. Sixty aligners were treated with Fresh Guard (Efferdent, Lynchburg, VA, USA), and the other 60 were treated with Corega (GlaxoSmithKline, London, UK) tablets and stored in a glass of water. Results The colour stability of G-Aenial Flo was higher than that of the 3M ESPE fluid composite (p=0.040 and p=0.024). Our study determined that staining occurred in all the teeth we measured as a result of using aligner. Fresh Guard aligner cleaner caused more discoloration on Zendura and Duran aligners than Corega aligner cleaner (p<0.05). Taglus plaque was found to have more discoloration than Zendura and Duran aligner (p<0.05). Conclusion In conclusion, Duran clear aligners are preferable to other clear aligners in terms of discoloration. In addition, G-Aenial Flo can be recommended as an attachment or fluid composite because of its better color stability results.
隐形矫治器治疗是一种正畸治疗方法，通过3D打印机定制而成，无需使用传统的金属或陶瓷钢丝及托槽。它是一种现代正畸方法，用于在美观和功能上矫正需要矫正的牙齿位置。目的本研究旨在比较隐形矫治器全时使用15天后牙齿和隐形矫治器的变色情况。材料和方法研究组的20名患者使用隐形矫治器45天，包括三种不同的隐形矫治器各使用15天。此外，纳入20名患者作为对照组，以测量牙齿变色的差异。在所有侧切牙和尖牙的远中区域，为每位患者交叉放置使用G-Aenial（日本东京GC公司）和3M ESPE（美国明尼苏达州圣保罗）流动复合树脂制成的固位附件。测试了三种矫治器托盘（Zendura Flex（美国加利福尼亚州弗里蒙特Bay Materials LLC公司）；Duran（德国伊瑟隆ScheuDental GmbH公司）；以及Taglus（印度孟买Laxmi Dental Export Pvt. Ltd公司））、两种流动复合树脂附件和两种隐形矫治器清洁器的变色情况。每个矫治器使用15天，然后患者更换为下一个矫治器。使用VITA Easyshade V分光光度计（德国巴特萨克京根）从尖牙到尖牙的中三分之一和中平面评估矫治器和患者牙齿的颜色变化。患者使用隐形矫治器后立即使用一种矫治器清洁器，然后完成矫治器颜色值的测量。获得的120个矫治器分为两组。60个矫治器用Fresh Guard（美国弗吉尼亚州林奇堡Efferdent公司）处理，另外60个用Corega（英国伦敦葛兰素史克公司）片剂处理，并保存在一杯水中。结果G-Aenial Flo的颜色稳定性高于3M ESPE流动复合树脂（p=0.040和p=0.024）。我们的研究确定，由于使用矫治器，我们测量的所有牙齿都出现了染色。Fresh Guard矫治器清洁器在Zendura和Duran矫治器上造成的变色比Corega矫治器清洁器更多（p<0.05）。发现Taglus托槽的变色比Zendura和Duran矫治器更多（p<0.05）。结论总之，就变色而言，Duran隐形矫治器比其他隐形矫治器更可取。此外，由于G-Aenial Flo具有更好的颜色稳定性结果，可推荐其作为附件或流动复合树脂。
