Summary:Purpose: In recent years, a method for improving gummy smiles in adults using an orthodontic anchor screw has been reported, but there is yet to be a treatment for the gummy smiles of those in the growth period. Methods: We improved the gummy smiles of three class II patients with vertical excessive growth of the upper jaw, during their growth period, using a simple bite jumping appliance (SBJA) and a high pull J-hook headgear. Results: It was found that SBJA promoted mandibular growth and the high-pull J-hook headgear inhibited the vertical growth of the maxillary anterior teeth. Conclusion: It is suggested that a combined use of high-pull J-hook headgear and SBJA is an effective way of improving gummy smiles in class II patients with vertical excessive growth of the upper jaw during their growth period.
