Class III malocclusion associated with skeletal anterior open bite pattern im adults can be a challenging orthodontic problem, especially if treated nonsurgically. Conventionally, several treatment alternatives are available such as tooth extraction, molar intrusion, and absolute anchorage system or orthognathic surgical correction. Acorrection with surgery may be themost effective and stable way. The article presents a case report of a 20 years old unilateral cleft lip and palate patient with skeletal Class III and long face syndrome(severe anterior open bite) treated by orthodontic compensation (lower first premolars extraction) followed by vertical reduction genioplasty. Post treatmentthepatient obtained satisfactory occlusion aswell as functional results with correction of severe anterior openbiteandreverse overjet.
