The most common type of early Class II Division I malocclusion is dental alveolar in development. It is the type of maloccusion that is etiologically environmental in nature, but delay in treatment can influence negative changes in dental, facial and skeletal pattern. This malocclusion is readily available for interception at age 7 or 8 to achieve a state of dental and skeletal normalcy with a protocol of defined objectives and predictable outcomes. With efficient and effective arch development (NPE) and utility arch wire (UAW) mechanics, a state of normalcy can be achieved within nine to twelve months of treatment.
早期安氏II类1分类错牙合最常见的类型是牙槽骨发育型。这种错牙合类型本质上是由环境因素导致的，但治疗延迟会影响牙齿、面部和骨骼形态的负面变化。这种错牙合在7至8岁时很容易进行阻断性治疗，通过明确的目标方案和可预测的结果，实现牙齿和骨骼的正常状态。通过高效的牙弓发育（NPE）和功能弓丝（UAW）技术，在治疗的9至12个月内即可实现正常状态。
