Abstract

Whole dentition intrusion and distalization poses great challenge in orthodontics due to complex mechanical design and possible anatomical limits. This case report illustrates the orthodontic retreatment of a class I hyperdivergent patient by the “high-pull palatal gear” (HPPG) technique and two mandibular miniscrews. The gummy smile was corrected and the profile was successfully improved through whole arch intrusion and distalization and subsequent forward rotation of the mandible.
