A method is presented for the accurate application of the modified 3-3 retainer of multistrand wire described by Zachrisson . This lingual retainer or splint is noninvasive of dental tissue and is reversible. Wire breakage does not appear to occur, and the slightly elastic properties of the wire allow a physiologic mobility of the teeth, which is of advantage in the periodontal patient. The only breakage that may occur is of the composite bond, although this appears to be less than with bonded brackets, but repair is quick and simple. The present method is now offered to add simplicity, speed, and accuracy to the important advantages already enjoyed, widening the scope for employment of this type of retainer to as many as eight or ten teeth in a series and, perhaps more significantly, to the maxillary anterior teeth, even where a deep bite exists. The value of the method is also seen when an active orthodontic appliance is removed and retention or splinting is required within an hour or two, as for the patient who is concurrently undergoing periodontal treatment.
本文介绍了一种精确应用由扎克里松描述的多股丝改良3 - 3固位器的方法。这种舌侧固位器或夹板对牙体组织无创且可逆转。似乎不会发生钢丝断裂，钢丝的轻微弹性特性允许牙齿有生理性移动，这对牙周病患者有利。可能发生的唯一断裂是复合粘结处的断裂，尽管这种情况似乎比粘结托槽时少，但修复快速且简单。现提供的这种方法在已有的重要优点基础上增加了简便性、速度和准确性，将这种固位器的应用范围扩大到连续多达八颗或十颗牙齿，也许更重要的是，甚至可用于存在深覆合的上颌前牙。当拆除活动正畸矫治器并在一两个小时内需要进行保持或夹板固定时，比如对于同时正在接受牙周治疗的患者，这种方法的价值也很明显。
