This article has presented three soft-tissue surgical techniques that have been shown to alleviate the relapse of orthodontically treated teeth in three specific situations: (1) rotations (and possibly also labiolingual irregularities), (2) extraction site closures, and (3) maxillary midline diastemas. The anatomy and histophysiology of the periodontium have been discussed briefly as they pertain to the rationale for these surgical procedures. None of the techniques discussed, if performed as indicated, will be detrimental to the supporting periodontal tissues and all can easily become a routine part of the clinician's standard retention therapy.
本文介绍了三种软组织外科技术，这些技术已被证明在三种特定情况下可减轻正畸治疗牙齿的复发：（1）牙齿旋转（以及可能存在的唇舌向不整齐），（2）拔牙位点关闭，以及（3）上颌中线间隙。本文简要讨论了牙周组织的解剖结构和组织生理学，因为它们与这些外科手术的原理相关。如果按指示进行操作，所讨论的任何技术都不会对支持性牙周组织造成损害，并且所有这些技术都可以轻松成为临床医生标准保持治疗的常规组成部分。
