Auxiliary buttons are often required in clear aligner therapy for elastic traction. We introduce an adhesiveless flame-fusion technique for affixing auxiliary metal buttons to clear aligners, aiming to eliminate the extra chair time, occasional debonding, and translucent haze associated with resin adhesives. Round‑base stainless‑steel buttons are grasped with locking forceps, heated in an alcohol flame (600-650 °C for 10-15 s), and immediately pressed with moderate manual pressure (5 N) for 5-10 s onto 0.75 mm polyethylene terephthalate glycol (PETG) aligners that are fully seated on working models to prevent distortion. Clinical use has shown the buttons remain firmly embedded under routine intra‑ and inter‑arch elastic forces without compromising aligner fit or transparency, while bonding can be completed in well under a minute. This simple, cost-effective protocol is readily adaptable to most commercial aligner systems and avoids the drawbacks of adhesive bonding, including extra chair time, occasional debonding, and the translucent haze associated with resin adhesives.
在透明矫治器治疗中进行弹性牵引时，通常需要辅助按钮。我们介绍一种用于将辅助金属按钮固定到透明矫治器上的无粘合剂火焰熔接技术，旨在消除与树脂粘合剂相关的额外就诊时间、偶尔的脱粘以及半透明雾状现象。用锁定镊子夹住圆底不锈钢按钮，在酒精火焰中加热（约600 - 650°C，持续10 - 15秒），然后立即用适度的手动压力（约5 N）按压5 - 10秒，压在完全就位在工作模型上的0.75毫米聚对苯二甲酸乙二醇酯（PETG）矫治器上，以防止变形。临床应用表明，在常规的牙弓内和牙弓间弹性力作用下，按钮仍能牢固地嵌入，而不会影响矫治器的贴合度或透明度，同时粘结可在不到一分钟内完成。这种简单、经济高效的方法很容易适用于大多数商业矫治器系统，并且避免了粘合剂粘结的缺点，包括额外的就诊时间、偶尔的脱粘以及与树脂粘合剂相关的半透明雾状现象。
