微创技术在拔除下颌第一磨牙中的应用

目的：探讨应用微创技术拔除下颌第一磨牙的优越性。方法：对要求拔除下颌第一磨牙的126个复杂病例，分别采用微创拔牙法（观察组）与传统劈凿法（对照组）两种方法拔牙，对手术时间、术中和术后并发症进行比较。结果：观察组因紧张而引起的血压、心律变化较小；术中断根率及拔牙窝不完整率观察组明显低于对照组；观察组患者术中痛苦的程度及发生率也不及对照组；术后疼痛肿胀反应对照组多于观察组；观察组拔牙时间缩短。结论：应用微创技术拔除下颌第一磨牙优于传统拔牙方法，值得推广。

Clinical Use of Minimally Invasive Techniques in Extraction of Mandibular First Molar

Objective：To evaluate the superiority of the minimally invasive technology applying in ex-traction of mandibular first molar .Method：126 patients who required having the mandibular first molar ex-tracted were randomly assigned to two groups in this study .Tooth extraction of the observation group used minimally invasive method , the control group used traditional chisel .Then Compare the operation time , intr-aoperative and postoperative complications of the two groups .Result： The data showed that the changes in blood pressure and heart rate caused by stress in patients with minimally invasive extraction group were smal -ler than those of patients with traditional extraction method .In the observation group , the rate of the root frac-ture and the alveolar socket incomplete was lower , intraoperative or postoperative pain of the patients was smaller, the surgery time was shorter .Conclusion：The uncomfortable feeling in patients with minimally in-vasive extraction was significantly lesser than the patients with traditional method .This kind of tooth extrac-tion is superior to the traditional method and it is worthy to be recommended .
