RESUMO
The objective of this clinical paper is to demonstrate an effective process to achieve relative long-term functional and aesthetic stability after the treatment of skeletal tongue source open bites. This therapy consisted of applying Delaire's architectural analysis as the cephalometry to make treatment plan corresponding to the patients' own craniomaxillofacial integral architectural structure to achieve the optimal skeletal anteroposterior and vertical position. In addition, glossoplasty and transverse matching of upper and lower arches must be under consideration in the goal of achieving integral biomechanical functional balance and aesthetic harmony. Little relapse of both skeleton and occlusion was found more than 3 years posttreatment. The effect of pararthria correction coursed by lingual functional impediment is also attained.
