Abstract
Orthodontic tooth movement was performed on five monkeys (Macaca nemistrina). Oral health was established and exploratory surgery was performed to assess the level of the connective tissue attachment and marginal bone. Measurements of the gingival margin and mucogingival junction were taken and orthodontic forces were applied. The central incisors were moved labially a mean distance of 3.05mm. Post therapy measurements were performed to assess the change which occurred as a result of tooth movement. Significant recession of the gingival margin, connective tissue level and marginal bone was found when compared to an amalgam marker located on the facial surface of the displaced central incisors. The distance from the amalgam marker to the mucogingival junction increased enough to compensate for the decreasing effect of the recession on the width of the keratinized gingiva
