The missing of the upper incisors especially would assume a serious aspect, and could be treated by three methods of orthodontic treatment, prosthodontic treatment and autotransplantation of the premolar teeth. The patient of this report had the skeletal class II malocclusion with the left upper central incisor missing, and have been treated with the fixed appliance after extraction of the right upper central incisor and both lower second premolars. The results were obtained as follows:
1. Treatment was done for 1 year 6 months.
2. Normal overbite and overjet were achieved.
3. Cuspal interdigitation was obtained normally.
4. Space problem was resolved with resin restoration of the upper lateral incisors.
5. The upper canines were used as the upper laterals after cuspal contouring.
6. Retention would be required with adequate retainers for a long time to prevent relapsing after treatment.
