Missing maxillary lateral incisors create an esthetic problem with specific orthodontic and prosthetic considerations. The purpose of this article is to describe treatment protocols and problems encountered in the management of this disorder.
The two common treatment options are orthodontic space opening for future restorations or orthodontic space closure using canines to replace the missing maxillary lateral incisors. The required amount of space opening and the various prosthetic options are discussed. The methods for reshaping canines in orthodontic space closure and building them up to simulate lateral incisors also are described. The indications, advantages and disadvantages of both treatment modalities are outlined to help clinicians make decisions in borderline situations.
Teamwork between the orthodontist, general practitioner and restorative dentist is important when analyzing factors related to individual patients and establishing overall treatment plans. This also will allow treatment modalities and the various options for replacing missing maxillary lateral incisors in space opening to be discussed between team members and the patient.
上颌侧切牙缺失会引发美学问题，并涉及特定的正畸和修复考量。本文旨在描述该病症治疗方案及治疗中遇到的问题。
两种常见的治疗选择是为未来修复进行正畸扩弓，或利用尖牙正畸关闭间隙以替代缺失的上颌侧切牙。文中讨论了所需的扩弓量及各种修复选择。还描述了在正畸关闭间隙时重塑尖牙并将其垫高以模拟侧切牙的方法。概述了两种治疗方式的适应证、优缺点，以帮助临床医生在临界情况下做出决策。
在分析个体患者相关因素并制定总体治疗计划时，正畸医生、全科医生和修复牙医之间的团队合作很重要。这也将使团队成员与患者能够讨论治疗方式以及在扩弓时替代缺失上颌侧切牙的各种选择。
