[Intercepted orthopedic treatment of skeletal maxillary protrusion deformity]

Maxillary protrusion deformity may be divided into three types: functional, skeletal and their combination. The diagnosis of which should be differentiated carefully. The treatment of skeletal maxillary protrusion is very difficult. It must be diagnosed in the growing stage of children and treated with intercepted orthopedic appliance in time. In order to bring the mandible into harmony with maxilla, the growth of maxilla should be inhibited while the mandible is stimulated. In this article an efficient orthopedic appliance using orthopedic force to inhibit the growth of maxilla was introduced. The factors which influenced the orthopedic effect were introduced by cases report. The use of the roentgenography cephalometric in diagnosing the maxillary protrusion deformity was discussed.
