Orthodontic treatment of Class II Division 2 malocclusion with gummy smile and deep bite is a challenge under the circumstances of lacking skeletal anchorage device. In this case report, we illustrated a miniscrew-assisted orthodontic retreatment of a 29-year-old female patient, who came to our department with a chief complaint of her unpleasant smile. The patient had previously undergone orthodontic treatment with 4-bicuspid extractions to correct her protrusive incisors. The clinical examination revealed a Class II division 2 malocclusion, 100% overbite, and a gummy smile. The philosophy of the orthodontic retreatment in this case was to correct Class II molar relationship and the deep bite while improving her excessive gum display simultaneously. With the aid of the temporary anchorage devices, we were able to predictably achieve the treatment goals without deteriorating the facial profile. The patient was satisfied with the posttreatment esthetics and occlusion, and the treatment result remained stable after one-year follow up.
