Patients were aged 6 to 15 years. The first group (197 patients) was treated without teeth extraction, 2nd group had teeth extracted. The treatment of dentition anomalies was effective both in decidual and permanent occlusion. The duration of treatment, number of visits per one definitive course were virtually equal in both groups. The authors believe teeth extraction expedient only in grade II constriction of dental arches, grade I to II construction of apical basis and medial teeth shift with space unavailable for restricted teeth at least for 1/2 crown width, and in absolute or relative macrodontia.
患者年龄在6至15岁之间。第一组（197名患者）未拔牙进行治疗，第二组进行了拔牙。牙列异常的治疗在乳牙列和恒牙列中均有效。两组治疗持续时间、每个确定疗程的就诊次数实际上相等。作者认为，仅在牙弓II级缩窄、根尖基底I至II级结构异常以及内侧牙齿移位且受限牙齿至少有1/2冠宽的空间不可用时，以及在绝对或相对牙体过大的情况下拔牙才是合适的。
