摘要： 目的: 通过采用超声骨刀和凿骨法拔除下颌第三磨牙断根比较两者临床效果。方法: 选取2017年1月~2018年1月期间在我院口腔外科拔除下颌第三磨牙发生断根患者200例,随机分传统组99例和实验组101例,两组断根前均采用微创拔牙理念技术,断根后传统组常规凿骨法取出断根,实验组采用超声骨刀取出断根,对两组手术时间、并发症进行统计分析。结果: 传统组时间(13.11±2.14) min,实验组时间(19.57±3.11) min。实验组取出断根时间长于传统组(P<0.05),两组术后均完整取出断根。实验组无血管神经损伤,传统组有4例神经损伤。传统组有8例出现舌侧骨板断裂,其中有3例断根进入舌下、下颌下及咽旁间隙。实验组术后并发症低于传统组(P<0.05)。结论: 采用超声骨刀取出下颌第三磨牙断根,明显降低术中及术后并发症,优于传统骨凿法。应用微创理念,配合超声骨刀,给予患者舒适化、无痛化的操作,具有较好的临床意义。

Abstract: Objective: To compare the clinical effects of ultrasonic bone knife and chisel in extraction the broken root of mandibular third molars. Methods: A total of 200 patients with root fractures of mandibular third molar were enrolled from 2017,1 to 2018,1. The patients were randomly divided into the traditional group (99 cases) and the experimental group (101 cases). Both groups were treated with minimally invasive extraction before root fracture. Conceptual technology, the traditional group of conventional bone-cutting method was used to remove the root after root-cutting. The experimental group used the super-bone knife to remove the root, and statistical analysis was performed on the operation time and complications of two groups. Results: The time of the traditional group was (13.11±2.14) min, and the experimental group was (19.57±3.11) min. The root withdrawal time of the experimental group was longer than that of the traditional group (P<0.05), and the roots were completely removed after operation. There was no vascular nerve injury in the experimental group, and there were 24 cases of nerve injury in the traditional group. In the traditional group, 8 cases had lingual bone plate fracture, and 3 cases were broken into the sublingual, submandibular, and parapharyngeal spaces. The postoperative complications in the experimental group were lower than those in the traditional group (P<0.05). Conclusion: Ultrasonic osteotome, when removing the root of the mandibular third molar, significantly reduces the intraoperative and postoperative complications. The piezoelectric bone knife has good clinical significance.
