The decision to close maintain, or open space at the agenesis sites of the maxillary lateral incisor and mandibular second premolar is generally based on several factors, including the class of malocclusion, skeletal pattern (divergence), esthetics, function, and periodontics. Replacement of congenitally missing maxillary lateral incisors, the second most commonly missing teeth, can involve (1) canine replacement, (2) tooth-supported restoration, and (3) implants. This paper contrary to the opinion of other authors, favors replacement of the congenitally missing lateral incisors in one of several ways, versus orthodontic space closure.
在上颌侧切牙和下颌第二前磨牙牙胚缺失部位决定关闭、维持或开辟间隙，通常基于几个因素，包括错颌类型、骨骼模式（差异）、美观、功能和牙周情况。先天性缺失的上颌侧切牙是第二常见的缺失牙，其替代方法可包括：（1）尖牙替代；（2）牙支持式修复；（3）种植体修复。与其他作者的观点相反，本文支持采用几种方法之一替代先天性缺失的侧切牙，而非正畸关闭间隙。
