The purpose of this study was to cross-sectionally evaluate the effects of postoperative training with chewing gum on masticatory efficiency, maximum bite force and masticatory movement in patients who underwent surgical orthodontic treatment. The subjects consisted of 23 skeletal Class III patients who had been followed-up for more than 5 years since their active treatments and were classified into two groups: one group consisted of 11 patients who were given the training with chewing gum to improve their masticatory function (Training group) and the other 12 patients who received no training at all (Nontraining group). Furthermore, the control was selected for evaluating the masticatory function phase of the subjects and was categorized into two details: one group consisted of 11 persons with normal dentition (Normal group) and the other group consisted of 10 skeletal Class III untreated persons (Non-treatment group). All the samples were adult females and did not have any clinical symptoms of temporomandibular disorders. The results were as follows. 1) The masticatory efficiency and maximum bite force of the Training group were recognized to be significantly much higher than in the Non-treatment group, and they got closer to the Normal group. However, there was no significant difference between the Non-training group and Non-treatment group. 2) The chewing stability of the Training group, Non-training group and Non-treatment group was less than or comparable to that of the Normal group. The surgical orthodontic treatment and training with chewing gum had no influence on the chewing stability.3) The chewing shape on the frontal plane of the Training group, Non-training group and Non-treatment group was narrower than that of the Normal group and was not influenced by the surgical orthodontic treatment nor training with chewing gum. 4) It was suggested that the postoperative training with chewing gum had effects on masticatory efficiency and maximum bite force, and that maximum bite force was one of the factors for improving masticatory efficiency. The following conclusions were obtained. The surgical orthodontic treatment and the postoperative training with chewing gum had little effect on chewing movement of skeletal Class III patients. However, it was suggested that the postoperative training with chewing gum has a positive influence on the learning 東北大学大学院歯学研究科口腔保健発育学講座顎口腔矯正学分野(主 任:五 十嵐 薫教授) *東北大学大学院歯学研究科口腔病態外科学講座顎顔面外科学分野(主 任:川 村 仁教授) Division of Orthodontics, Department of Life-long Oral Health Science, Graduate School of Dentistry, Tohoku University (Director: Prof. Kaoru IGARASHI) *Department of Oral Medicine and Surgery , Division of Maxillofacial Surgery, Graduate School of Dentistry, Tohoku University (Director: Prof. Hitoshi KAWAMURA) 14巻 3号 術後ガム咀嚼訓練が顎変形症患者の咀嚼機能に及ぼす効果 171 effect of the patients' masticatory system from the research results of having a significant beneficial effect on masticatory efficiency and maximum bite force.
