Transversal problems such as crowding and crossbite are one of the most common problems dealt with in early orthodontic treatments. Early correction of these problems may ease or even eliminate the future need for treatment. This paper presents the management of 2 cases with transverse discrepancy using the Ni-Ti Memory Leaf Expander--a new compliance-free slow maxillary expansion appliance. The total treatment time for both cases was 9 months. In both cases, the inter-canine, inter-premolar, and inter-molar distances, as well as the arch length, have all increased.
诸如牙列拥挤和反咬合等横向问题是早期正畸治疗中最常见的问题之一。早期纠正这些问题可能会减轻甚至消除未来的治疗需求。本文介绍了使用镍钛记忆叶扩弓器——一种新型无依从性慢速上颌扩弓矫治器——对2例横向差异病例的治疗情况。两例病例的总治疗时间均为9个月。在这两例病例中,尖牙间、前磨牙间和磨牙间距离以及牙弓长度均有所增加。
