BACKGROUND
This study reports a case in which a severely impacted lower first molar was recovered with a combined orthodontic therapy and minimally invasive oral surgery with special focus to patient's aesthetic demands.
CASE REPORT
A 12-year- old female patient was complaining delayed eruption of mandibular right first molar. Radiographic exam showed a severe tooth impaction with a close relationship between tooth roots and mandibular nerve. As the patient refused full arches orthodontic treatment, a partial orthodontic approach was projected. During treatment, temporary miniscrews were placed in both upper and lower arches, in order to allow dental movement with maximum anchorage. After a 24 month-therapy the tooth was extruded, so the appliance and the miniscrews were removed.
CONCLUSION
The present case shows that severe tooth impaction can be resolved with a combined partial orthodontic- minimally invasive surgical treatment.
背景
本研究报告了一例通过正畸治疗与微创口腔手术相结合的方法成功恢复严重阻生下颌第一磨牙的病例，特别关注了患者的美学需求。
病例报告
一名12岁女性患者主诉下颌右侧第一磨牙萌出延迟。影像学检查显示牙齿严重阻生，牙根与下颌神经关系密切。由于患者拒绝全牙弓正畸治疗，因此设计了局部正畸方法。治疗期间，在上、下牙弓均植入临时微螺钉，以实现最大支抗下的牙齿移动。经过24个月的治疗，牙齿被牵引出来，随后拆除矫治器和微螺钉。
结论
本病例表明，严重牙齿阻生可通过正畸与微创外科联合治疗得以解决。
