Air polishers are relatively new devices that have provided dentistry with an alternative method for cleansing the tooth surface. Many publications attest to the efficacy of the instrument in plaque and stain removal while advising the practitioner of potential health risks to the patient. In spite of the information available, little research has been published concerning air polishing procedures in the treatment of the tooth surface before placement of the orthodontic bracket. In light of the research supporting the efficacy of plaque and stain removal, the use of the air polisher has been shown to have no detrimental influence on the bonding of the resin bracket cement to the tooth surface. It would appear that the system may be ideal for use in conjunction with orthodontic treatment. The air-powder polisher has been found to be the most effective method of plaque removal for orthodontic patients without causing breakage of elastics or wires or loss of zinc phosphate or composite material. Another application for the air-powder polisher in the orthodontic practice is surface preparation of the tooth before bracket placement. The instrument should be held approximately 4 to 5 mm from the tooth surface, at a 60 degree angle for anterior smooth surfaces, at an 80 degree angle for posterior smooth surfaces, and at a 90 degree angle for occlusal surfaces. A constant circular motion should be used, with an exposure time of 30 to 60 seconds.
空气抛光机是相对较新的设备，为牙科提供了一种清洁牙齿表面的替代方法。许多出版物证实了该器械在去除牙菌斑和污渍方面的功效，同时也向从业者告知了对患者潜在的健康风险。尽管有这些可用信息，但关于在正畸托槽放置前使用空气抛光程序处理牙齿表面的研究却很少发表。鉴于有研究支持空气抛光机在去除牙菌斑和污渍方面的功效，已证明使用空气抛光机对树脂托槽粘结剂与牙齿表面的粘结没有不利影响。看来该系统可能非常适合与正畸治疗联合使用。已发现空气粉末抛光机是正畸患者去除牙菌斑最有效的方法，不会导致弹力线或钢丝断裂，也不会造成磷酸锌或复合材料脱落。空气粉末抛光机在正畸实践中的另一个应用是在托槽放置前对牙齿进行表面处理。该器械应距牙齿表面约4至5毫米，对于前牙光滑表面呈60度角，对于后牙光滑表面呈80度角，对于咬合面呈90度角。应采用持续的圆周运动，暴露时间为30至60秒。
