The application of real-time dynamic navigation in the extraction of low horizontally impacted mandibular third molars
Objective To evaluate the clinical efficacy of real-time dynamic navigation in the extraction of mandibular low horizontal impacted third molars,providing a reference for clinical application.Methods A total of 100 patients with mandibular low horizontal impacted third molars,who were treated at the Department of Oral and Maxillofacial Surgery,Xi'an Jiaotong University Stomatological Hospital from January 2023 to August 2023,were randomly divided into the experimental group(extraction with real-time dynamic navigation)and the control group(extraction with direct minimally invasive method),with 50 patients in each group.The study recorded the time required for preoperative planning,navigation setup,and surgery,as well as the occurrence of complications(injury to adjacent teeth and nerve damage).Results In the experimental group,the preoperative planning time was 10±3 minutes,the navigation setup time was 5±1 minutes,and the surgery time was 20±2 minutes.In the control group,the corresponding times were 0 minutes,0 minutes,and 35±2 minutes.The surgery time in the experimental group was significantly shorter than that in the control group(P＜0.01).No adjacent tooth or nerve injuries were observed in the experimental group,whereas 2 cases of adjacent tooth injury and 3 cases of lower lip numbness were noted in the control group.Conclusion The use of real-time dynamic navigation for the extraction of mandibular low horizontal impacted third molars enables precise visualization and segmentation of teeth,effectively shortens surgery time,and reduces the risk of adjacent tooth and nerve injuries,making it a valuable technique for clinical promotion.
