Planning extraction of teeth for orthodontic treatment is one of the challenging factors for successful functional and esthetic orthodontic results and for the long-term stability.
The aim of this study is to document possible extraction guidelines for planning of orthodontic treatment for space deficiency cases related to excess tooth material.
The guidelines are written as patterns to facilitate the decision of extraction of teeth for class I, class II division 1, class II division 2, and class III malocclusions, for crowding, overjet reduction, or correcting the buccal segment relationship. The decision for extraction of teeth for orthodontic treatment is enforced by the oral hygiene, carious teeth, periodontal involvement, impacted teeth, supernumeraries, hypodontia, or for orthognathic purposes. Also, planning the decision for accurate extraction pattern is the main factor in the success of the orthodontic treatment and for the long-term stability of the results.
Orthodontic tooth extraction should always be planned with consideration of the width and length of the face, the oral hygiene, carious activity, periodontal involvement, malformed crowns, length and health of the root of the teeth, prognosis of impacted teeth, supernumeraries, and hypodontia.
Accurate diagnosis and treatment planning following orthodontic extraction guidelines lead to a long-term stability of the corrected results.
为正畸治疗计划拔牙是实现成功的功能和美观正畸效果以及长期稳定性的具有挑战性的因素之一。
本研究的目的是记录与牙齿过多相关的牙列间隙不足病例正畸治疗计划可能的拔牙指南。
这些指南以模式形式编写，便于为安氏I类、安氏II类1分类、安氏II类2分类和安氏III类错牙合、牙列拥挤、减小覆盖或纠正颊侧段关系的病例做出拔牙决策。正畸治疗的拔牙决策受口腔卫生、龋齿、牙周病变、阻生牙、多生牙、牙列缺损或正颌目的的影响。此外，规划准确的拔牙模式决策是正畸治疗成功及结果长期稳定的主要因素。
正畸拔牙计划应始终考虑面部的宽度和长度、口腔卫生、龋病活动、牙周病变、牙冠畸形、牙根长度和健康状况、阻生牙的预后、多生牙和牙列缺损情况。
遵循正畸拔牙指南进行准确的诊断和治疗计划可使矫正结果长期稳定。
