Mesiodistal reduction of primary teeth is necessary in cases with mild or moderate primary crowding, in patients treated with Fränkel appliance type I or II or in those who need to keep a primary molar as long as possible due to congenitally missing premolars. In order to minimize the risks of periodontal destruction and caries, the tooth surface should be polished after grinding. A technique for stripping permanent teeth, recently proven successful in achieving smoother enamel than untreated tooth surfaces, was slightly varied and applied to primary teeth. By means of scanning electron micrographs, it could be shown that application of this technique produces smooth surfaces on primary teeth as well. The procedure is described in detail and cases in which it should be used are presented.
对于存在轻度或中度乳牙拥挤的病例、接受I型或II型Frankel矫治器治疗的患者，或因先天性前磨牙缺失而需要尽可能长时间保留乳牙磨牙的患者，乳牙的近远中减径是必要的。为了将牙周破坏和龋齿的风险降至最低，磨牙后应打磨牙齿表面。一种用于恒牙片切的技术最近被证明是成功的，该技术能使牙釉质比未处理的牙齿表面更光滑，对其稍作修改后应用于乳牙。通过扫描电子显微镜照片可以看出，应用该技术也能使乳牙表面光滑。本文详细描述了该操作过程，并列举了应使用该技术的病例。
