Mini-screw anchorage to accomplish en masse intrusion of the maxillary dentition during growth for reduction of excessive gingival display. by John M. Pobanz, DDS, MS
Case History and Analysis
An African-American 14-year and four-month-old female presents with the chief complaint of excessive gingival display. In her words: “Can you make it so that I don’t look like a horse?” She had not yet experienced the onset of menstruation. She presents with no significant medical or dental history affecting treatment planning and no complicating factors associated with the periodontium or oral tissues. The patient displays 8mm of gingiva upon smiling (Fig.1). Pre-treatment facial photographs (Fig. 2) show a convex profile bimaxillary protrusion. Cephalometric analysis (Fig.3) shows a Class II skeletal relationship, retrusive mandible. The lip profile is protrusive relative to the E-line. She is not lip incompetent. However, the molar and canine relationships are Class I. Overjet and overbite are normal.
