Tooth extraction is a common operation in oral surgery. Traditional-extraction instruments, such as bone chisel, elevator, and bone hammer, lead to not only severe trauma but also unnecessary complications, and patients easily become nervous and apprehensive if tooth extraction is performed using these violent instruments. In recent years, with the develop- ment of minimally invasive concept and technology, various micro-power instruments have been used for tooth extraction. This innovative technology can reduce the iatrogenic trauma and complications of tooth extraction. Additionally, this technology can greatly decrease the patient's physical and mental pressure. The new equipment compensates for the deficiency of traditional tooth extraction equipment and facilitates the gradual replacement of the latter. Diverse micro-power systems have distinct strengths and weaknesses, so some auxiliary instruments are still needed during tooth extraction. This paper focuses on the various micro-power systems for tooth extraction and tries to compare the advantages and disadvantages of these systems. Selection and usage of auxiliary equipment are also introduced. Thus, this paper provides reference for the proper application of the micro-power systems in tooth extraction.
牙拔除术是口腔外科最基本的治疗操作，但传统使用骨凿、骨锤等拔牙工具的方法不仅创伤大、并发症多，还易增加患者紧张、恐惧心理。近年来，随着微创理念的发展和技术的进步，各种微动力设备开始应用于牙拔除术，这些设施既能减少拔牙创伤、降低拔牙并发症，还可极大地减轻患者的身心压力，从而弥补了传统拔牙器械的不足并逐渐取代了传统拔牙工具。由于各种微动力系统具有不同的优势和缺陷，在操作过程中还需一些辅助设备。本文将针对各种微动力系统在牙拔除术中应用的优缺点和辅助设备的选择和使用方法进行阐述，为临床上如何选择和应用微动力系统提供参考。
