Resumen
1.Maxillary lateral incisor of the patient was microdontia. Bolton index discrepancy. The first orthodontic treatment closed the anterior teeth space, but didn’t take functional jaw of the patient into account, and the protruding jaw might cause occlusal interference After the first orthodontic treatment, space between anterior teeth was created, followed by functional facial asymmetric deformity (mandibular deviation, mental region to left). 2.Due to severe enamel demineralization of the patient and microdontia of 22, invisible orthodontic treatment was adopted for the second time. Jaw pillow had obvious advantages over fixation in removing occlusion interference. Crossbite of 22 was corrected with repair space reserved. 3.The patient had a slight overbite and Skeletal Class I. After treatment, Index Post Face Height/Ant Face Height (FHI) was decreased by 2.4°. The mandible rotated backward for 1mm. Overject of anterior teeth was increased. The maxillary central incisor was retracted for 2.7°. Labial inclination of lateral incisors was reduced. The original facial shape was basically maintained.
