This case shows where intrusion screws were used to intrude the incisors followed by a cosmetic gingivec-tomy and re-positioning of the leva-tor labialis apically. (Fig. 17-20) Bone screw anchorage is a conservative and effective method to reduce or prevent gingival display in orthodontic patients. A general practitioner performing orthodontic treatment with simple local anesthetic can do it. It is a conservative treatment alternative that, in most cases, has made maxillary impaction orthognathic surgery obsolete. REFERENCES 1. Rickettes M. Robert. The golden divider. JCO. 1981;15(11). 2.
