随着人民生活水平的不断提高,广大人民群众对医疗卫生的要求越来越高,洁齿为更多的人所关心。我国牙石发病是很高的,由此而引起的并发症很多,故牙石的治疗显得更为突出。目前世界上先进国家作牙科洁疗术大都采用超声刮牙器或气动洁牙器,而我国多数医院还是采用手动器械。超声牙刮器是通过具有压电效应的压电陶瓷,把脉冲电源的电能转换为超声机械振动,用振动能量击碎去除牙石,刮掉牙斑;气动浩牙器是靠气动牙科设备上的压缩空气的能量,推动一个振动片撞击振杆产生振动来刮除牙石、牙斑的。但这些进口设备太贵,因此很难在国内普及应用。
With the continuous improvement of living standards of the people, the masses of the people are increasingly demanding medical and health care. Dental care is of concern to more people. The incidence of dental calculus in China is very high, resulting in many complications, so the treatment of calculus is more prominent. At present, most advanced countries in the world use dental scrubs as dental scrubs or pneumatic scaler. However, most hospitals in our country still use manual instruments. Ultrasonic tooth scraper is through the piezoelectric effect of piezoelectric ceramics, the pulse power of electrical energy is converted to ultrasonic mechanical vibration, vibration energy crushed to remove the calculus, scraping plaque; pneumatic tooth is to rely on dental equipment The energy of compressed air, pushing a vibrating plate to vibrate the vibrating rod to scrape the calculus, plaque. However, these imported equipment is too expensive, so it is difficult to popularize the application in the country.
