摘　　要：目的:研究动态导航引导下精准化、微创化根尖手术新方法。方法:选取慢性根尖周炎、根尖区暗影久治不愈的患者1例,拍摄开口位CBCT;术前规划手术方案;导航器械识别配准标记;动态导航引导定位下进行去骨术和截根术。结果:动态导航引导下精准切除患牙根尖3 mm,最大程度减少了对骨组织和软组织的损伤,实现了精准化、微创化治疗。提高了患者的舒适度和满意度。结论:动态导航引导下的微创根尖手术可以实现术前模拟,术中可视化、精准化、微创化、简单高效,可以降低根尖手术的技术敏感性。Objective:To explore the new method for minimally invasive and accurate apical microsurgery with the aid of dynamic navigation systems.Methods:A patient suffered from chronic periapical periodontitis and failure of root canal therapy was selected.An open position cone beam computer tomography(CBCT)was made.Preoperative plan was made in IRIS software.The infrared lamp of navigation systems was matched and positioned before the surgery.Guided osteotomy and root resection were performed with the aid of dynamic navigation systems.Results:The periapical pathological tissue was removed accurately with minimal lesion to osseous and soft tissue.The minimally invasive and precise treatment was realized.The patient’s satisfaction was improved.Conclusion:Minimally invasive apical surgery with the aid of dynamic navigation systems would realize preoperative simulation,visualization,and accurate and minimal invasion.It was simple,efficient,and would lower the technique sensitivity.
