通过沿着0.018英寸唇弓和AlastiK链的滑动机构来缩回上颌尖牙的效率与使用Gjessing设计的尖牙缩回弹簧的效率进行了比较。在21名受试者中，通过这两种方法中的一种，在牙弓两侧研究了犬齿回缩和倾斜程度以及犬齿旋转的速率。与滑动机械装置相比，使用弹簧时犬回缩更快，远端倾斜更少。犬齿回缩弹簧在回缩期间控制犬齿旋转方面并不优于滑动机构上级。
The efficiency of maxillary canine retraction by means of sliding mechanics along an 0.018-inch labial arch and an AlastiK chain was compared with that using the canine retraction spring designed by Gjessing. The rate of canine retraction and degree of tipping, and rotation of the canine were studied in 21 subjects by one of these two methods on either side of the dental arch. Measurements were made in the mouth and on photographs of dental casts. The canine was retracted faster and with less distal tipping with the spring than with the sliding mechanics. The canine retraction spring was not superior to the sliding mechanics in controlling canine rotation during the retraction.
