摘　　要：正畸牵引是冠根折牙齿保存治疗的重要技术手段,尤其在前牙外伤的治疗中,通过正畸牵引可将龈下断段牵引至龈上,并联合多学科治疗,最大程度地恢复患者功能、改善美观。但是在临床应用中,正畸牵引缺乏预见性和精确的牵引指标,并且缺牙状态维持3~6个月影响患者伤后的身心健康恢复。本研究通过数字化技术精准设定牵引目标位置,制作导板准确实施牵引术,紧密联系修复治疗等一系列处理,提高整体治疗的可预知性、增加治疗成功率。Orthodontic extrusion is an important technical means for the preservation and treatment of crown-root fracture teeth,especially in the treatment of anterior tooth trauma.Combining with multidisciplinary treatment,the subgingival segment can be pulled to be supra-crestal through orthodontic extrusion.The patient′s function can be restored to the greatest extent and the aesthetics can be improved.However,the current orthodontic traction lacks predictability and accurate traction indicators,so that patients need to be partially edentulous for 3-6 months,which greatly affects the physical and mental health of patients after injury.In this study,a series of treatments such as accurately setting the traction target position,making a guide plate to accurately implement traction,and closely linking repair therapy were used to improve the predictability of the overall treatment and increase the success rate of treatment.
