Past, Present and Future Views of the Jaw Deformity Studies. Analysis Subjects of Past Fourteen Years: Part 2.

All of the subjects that had been presented during the last 14 years in Japanese Study Group of Jaw Deformities, which was recently renamed Japanese Society for Jaw Deformities, have been reviewed in detail.The results were as follows: 1) It is time to improve the typical operative methods. 2) Treatment of jaw deformity with the medical complications, failure cases, and long-term observed cases must be investigated. 3) Although there were many clinical presentations at the beginning, the number of basic research presentations have been increasing. 4) It seems that a long time would be required to elucidate causes and pathological conditions of jaw deformities as well as to establish preventive measures. Therefore, the current therapeutic methods, that is, “preoperative orthodontics-operation-postoperative orthodontics”, would continue to be the main stream.We would like to establish the institution as, “Center for Jaw Deformity” to research causes and methods of treatment for severe jaw deformities. An orthognathic surgical system controlled by medical electron machines and nonsurgical treatment is expected to be developed in the future.
