正畸拔牙矫治中尖牙远中移动影响因素的研究进展

Research progress on factors influencing canine distal movement in orthodontic extraction treatment

摘要

针对牙齿前突或拥挤病例，减数治疗可利用拔牙间隙实现排齐与前牙内收，是目前临床矫治的常用手段之一。尖牙能否实现精准远中移动，直接影响前牙内收效率与侧貌改善程度，是减数治疗的关键步骤。目前，国内外学者围绕尖牙远中移动的生物力学机制及临床策略已开展大量研究，但尚缺乏针对解剖因素、并发症与临床策略的系统整合分析。本文通过全面检索并深度分析近年来相关研究，梳理尖牙远中移动的生物学机制及相关影响因素，为临床医生提供更具操作性的理论与实践参考。

Abstract

For patients with dental protrusion or crowding, extraction therapy is a common clinical approach that utilizes the space created by tooth extraction to achieve alignment and anterior teeth retraction. The precise distal movement of the canine is a critical step in this therapy, as it directly affects the efficiency of anterior retraction and the degree of profile improvement. To date, scholars worldwide have conducted extensive research on the biomechanics mechanism and clinical strategies of canine distal movement. However, a systematically integrated analysis of anatomical factors, complications, and clinical strategies remain limited. This paper comprehensively reviews and analyzes recent studies to summarize the biological mechanisms and influencing factors of canine distal movement, aiming to provide clinicians with more operable theoretical and practical references.
