The lower fixed retainer from cuspid to cuspid has been one of the commonly used methods of retention at the end of the orthodontic treatment. Orthodontists mostly use the lingual wire soldered to cuspid bands for the fixed lower retainer. With the advent of the new effective bonding materials many orthodontists prefer to use cuspid-to-cuspid/biscuspid-to-biscuspid bonded retainers to obtain optimal retention of lower anterior teeth both functionally and aesthetically. After experimenting with a variety of previous methods, such as the use of rubber bands, elastic threads, cotton pliers, ligature wires and silastic trays for the accurate placement and immobilization of a lower lingual retainer during the bonding, we have found that the use of two 1 to 1 1/2 inch pieces of 0.016 inch wires tack welded to lingual wire gives the best results. It is more accurate, simple, inexpensive and designed to save the orthodontist chair time.
从尖牙到尖牙的下颌固定保持器一直是正畸治疗结束时常用的保持方法之一。正畸医生大多使用焊接在尖牙带环上的舌侧丝作为下颌固定保持器。随着新型有效粘结材料的出现，许多正畸医生更倾向于使用从尖牙到尖牙/从双尖牙到双尖牙的粘结保持器，以便在功能和美观方面都能实现下颌前牙的最佳保持效果。在试验了多种以前的方法，如使用橡皮筋、弹力线、棉钳、结扎丝和硅橡胶托盘来在粘结过程中精确放置和固定下颌舌侧保持器之后，我们发现使用两段1至1.5英寸长的0.016英寸钢丝点焊到舌侧丝上能取得最佳效果。它更精确、简单、便宜，而且旨在节省正畸医生的椅旁时间。
