Absence of the maxillary lateral incisor creates an aesthetic problem which can be managed in various ways. The condition requires careful treatment planning and a consideration of the options and outcomes following either space closure or prosthetic replacement. Recent developments in restorative dentistry have warranted a re-evaluation of the approach to this clinical situation. Factors relating both to the patient and to the teeth, including the presenting malocclusion and the effect on the occlusion, are considered. This review considers the possible options: no treatment; orthodontic space closure with canine modification; space maintenance and replacement of the missing tooth with denture, bridge (adhesive and conventional), or implant.
上颌侧切牙缺失会造成美学问题，对此可采用多种方法处理。这种情况需要进行仔细的治疗规划，并考虑关闭间隙或进行修复性替代后的各种选择和结果。口腔修复学的最新进展值得对这种临床情况的处理方法进行重新评估。要考虑与患者和牙齿相关的因素，包括当前的错牙合情况以及对咬合的影响。本综述探讨了可能的选择：不治疗；通过改变尖牙进行正畸间隙关闭；间隙保持以及用义齿、桥体（粘结式和传统式）或种植体替代缺失牙。
