Fig. 6a Fig. 6b Fig. 7a Fig. 7b Conclusion General and pediatric dentists should understand the controversy surrounding the issue of Early versus Late Class II orthodontic treatment. The clinician must be able to quantify the unique benefits of early Class II treatment by unlocking the occlusion and allowing proper growth modi-fication of the mandible. This article compares a conventional late mixed denti-tion treatment with a unconventional early mixed denti-tion protocol to support the unique benefit of early mixed dentition Class II treatment. 14,15 (Fig. 6a, 6b)(Fig. 7a,7b) 5.
