The maxillary lateral incisors are the most frequently missing teeth after the third molars. The cases with congenitally missing lateral incisors are treated either by orthodontically closing the spaces or by space regaining for prosthetic restorations. Malocclusion is the most effective factor for selecting the treatment method. Besides the characteristics of the malocclusion and interdigitation, the colour, the shape, the size and the position of the canines effect the treatment planning. In particular, Class II Div. 1 and Cl. I anterior crowding cases are the most convenient cases for orthodontically closing the missing lateral spaces. In these cases besides the treatment of the present malocclusion the reshaping of the canines is aimed and these teeth are moved to lateral spaces. In this article the treatment of a Cl. II Div. 1 malocclusion case with congenitally maxillary missing lateral incisor with Begg technique will be presented. The changes and variations of the Begg mechanics applied for this case will be discussed.
上颌侧切牙是继第三磨牙之后最常缺失的牙齿。先天性侧切牙缺失的病例可通过正畸关闭间隙或恢复间隙以进行修复治疗。错牙合是选择治疗方法的最有效因素。除了错牙合和牙合接触的特征外，尖牙的颜色、形状、大小和位置也会影响治疗计划。特别是安氏II类1分类和安氏I类前牙拥挤病例是正畸关闭侧切牙缺失间隙最适宜的病例。在这些病例中，除了治疗当前的错牙合外，还旨在对尖牙进行塑形并将这些牙齿移至侧切牙间隙。本文将介绍一例使用Begg技术治疗先天性上颌侧切牙缺失的安氏II类1分类错牙合病例。还将讨论针对该病例应用的Begg矫治技术的变化和差异。
