A conservative compression surgical orthodontic method for treating upper prognathism in adults

: A clinical example of effective treatment of an adult patient with combined deformations of the jaws (upper prognathism of the third degree and open occlusion of the second degree) is reported. Fragmented osteotomy of the maxilla at the level of symmetrical removal of second molars is performed. Due to Engle's arches soldered with Vasil'ev's splint and compression, a maxillary fragment was shifted 10 mm backward and downward at the expense of compressing the inter-root septae; the first molars were preserved. Diastemata and tremata between incisors of both jaws were eliminated by the same method.
