Maxillary incisor intrusion and facial growth.
A palate and first molar anchorage appliance is used to intrude upper incisors, and the effects on dental and skeletal variables are examined in 25 growing females and 25 matched controls. On average, the mandible was unaffected for the entire treated sample, but those with the largest reduction in overbite showed more increase in mandibular length than expected.
