Fig. 11. Premolars were extracted in the initial treatment. Anterior bite turbos were boned on the lower arch for bite opening.
Fig. 12. Class III elastic provided horizontal and vertical forces to improve canting in the lower arch and to facilitate early correction of Class III relation.
Fig 13. 7th month of treatment. leveling of right maxillary canine and the lower-occlusal plane canting were improved. Positive overjet was also achieved.
Fig. 14. Asymmetrical elastics and a pre-torque NiTi wire were introduced in the 11th month of treatment. (Arrow: lower 3-3 ART)
Fig. 15. A L-shape Class III vector elastic was utilized for space closure, settling posterior bite and better interdigitation.
