Abstract
The anterior teeth of five adult pigtail monkeys were moved lingually to correct a previously induced labioversion. These teeth were retained in their more normal arch positions for five months, after which clinical and histologic measurements were made of the periodontium. The untreated cuspids served as controls. Measurements were made to record changes in the gingival margin, the mucogingival junction, the width of keratinized gingiva and the marginal bone level relative to a fixed point on the tooth crowns. Oxytetracycline was administered three times to label areas of osteogenesis in the periodontium.
The incisors were retracted a mean distance of 1.8 mm lingually. The marginal bone level increased (moved coronally) a mean of 2.8 mm for upper and lower incisors combined. The intreated cuspids had a loss of 1.08 mm marginal bone (moved apically). Soft tissue effects were slight. The oxytetracycline labels showed that osteogenesis occurred in the periodontium to a significant degree.
Tooth position, in this study with monkeys, was determined to be significantly correlated to good periodontal support by bony tissue.
