A 28-year-old female with a skeletal Class III malocclusion, missing her upper first premolars, retroclined
upper, lower incisors and premature contact at 21 and 31 that caused anterior sliding when she bit and her chin
shifted to the left was treated by orthodontic alone. Her lower second premolars (35, 45) and lower third molars
(38, 48) were extracted during orthodontic treatment. Correction of the Class III malocclusion and upper space
closure were achieved by Class III elastics. Prevention of retroclination of lower incisors during space closure was
performed by adding gable bend to arch wire. The active treatment period was 30 months. The one-year retention
showed that the treatment results were quite stable.
