Materials consisted of cephalograms which were taken from 20 Japanese with reversed occlusion Study was made of the 2 dimensional changes in cephalograms before and after treatment, in order to determine its value for the estimation of the mandibular position after treatment of reversed occlusion, for therapeutic purposes, and also its value as a rotational element in preparation of Ricketts' V.T.O. Superimposed cephalometric tracings were made in the pretreatment and posttreatment rest positions. Using these, the method was evaluated for current use in analysis. The superimposition of tracings enabled estimation of the mandibular position and habitual position with an accuracy of 80% (16/20 cases). Coincidence of posttreatment mandibular position and pretreatment rest position was obtained in all adult cases. Utilization of the rest position for preparation of Ricketts' V.T.O. made it possible to estimate the growth direction and the mandibular position with an accuracy of 65%. Superimposition of pretreatment rest position and posttreatment habitual occlusal position led to coincidence of V.T.O. 84% of the time. Case analysis by means of Rákosi's functional analysis was effective for the determination of the relative therapeutic difficulty and the therapeutic approach. Utilization of the rest position, in addition to Kim's ODI and APDI values proved to be capable of determining the exact therapeutic plan at a probability of 70%. The above results revealed that the preoperative rest position was effective, not only for functional analysis, but also for the estimation of the therapeutic goal for adult cases and of the first stages-completion (at the overjet correction) for young cases.","PeriodicalId":12643,"journal":{"name":"Gifu Shika Gakkai zasshi = The Journal of Gifu Dental Society","volume":"16 1","pages":"189-215"},"PeriodicalIF":0.0,"publicationDate":"1989-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13779027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EMG recordings were analyzed during rest position, maximal clenching and maximal clenching with a cotton-roll. Mandibular movement was examined for path of closure, amount of freeway, maximal velocity of jaw opening and closing, condylar test and amount of maximal vertical jaw opening. The results of the investigation revealed the following. Normal occlusion and prognathia were classified into two groups by path of closure. One group was going toward the upper front and another toward the upper back. The former was indicated in 77% of normal occlusion and 65% of prognathia cases examined. Amount of freeway space was the same in both groups. Maximal velocity of jaw was significantly (p less than 0.05) faster for prognethia than for normal occlusion. Condylar test was significantly (p less than 0.05) greater for prognathia than for normal occlusion. Temporal muscle activity was greater for normal occlusion than for prognathia. During maximal clenching, temporal muscle activity was greater than masseter activity in the normal occlusion. A tendency toward negative correlation was found between temporal muscle activity during maximal clenching and the mandibular plane angle, facial height and gonial angle. The same tendency was found between masseter muscle activity and the mandibular plane angle, facial height, ramus-height and gonial angle. These results prove that it is important to examine muscle activity and mandibular movement to make treatment planning.","PeriodicalId":12643,"journal":{"name":"Gifu Shika Gakkai zasshi = The Journal of Gifu Dental Society","volume":"16 1","pages":"147-63"},"PeriodicalIF":0.0,"publicationDate":"1989-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13779025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Mandibular movement and electromyogram investigation of normal occlusion and reversed occlusion before and after correction of over jet].","authors":"T Maeda","doi":"","DOIUrl":"","url":null,"abstract":"The purpose of this investigation was to understand how the mandibular movement and myofunction in reversed occlusion, approach to normal occlusion after the correction of over jet. The experiment was carried out in 30 normal and 26 reversed occlusion school children patients who were classified into 3 groups by morphological analysis. A K6 diagnostic system was used. It recorded muscle activity of maximum clenching, free way space, path of closure, and the maximum velocity of opening and closing mandibular. And recorded a condylar test at the same time. Reversed occlusion classified 3 groups: upper and lower incisor had improper inclinations (D group, 19%), construction bite possible but recognized back and forth discrepancy between maxilla and mandibular (FS group, 50%), discrepancy larger than FS group and construction bite not possible (S group, 31%). Toward upper forth group indicated 77% and toward upper back group indicated 23% in normal occlusion. As for reversed occlusion the former indicated 92% and the latter indicated 8%. Differences in connection with orthodontic appliance and period of treatment were not so large. Back and forth mandibular movement, as measured by a condylar test, was greater for reversed occlusion than for normal occlusion, but this value tended to decrease after orthodontic treatment. In reversed occlusion, maximum opening, free way space, maximum velocity of opening and closing and muscle activity of rest position didn't show significant difference (p less than 0.05) among each group before and after the correction of over jet. Temporalis and masseter activity of maximum clenching, except temporalis among the D group, approached the values for normal occlusion. In the S group, muscle activity of maximum clenching with a cotton-roll, was lower before treatment, but approached to data in normal occlusion. These results prove that improvement of over jet in reversed occlusion, by ordinary orthodontal diagnosis and treatment plan, quasi-normalizes mandibular movement and muscle activity in reversed occlusion.","PeriodicalId":12643,"journal":{"name":"Gifu Shika Gakkai zasshi = The Journal of Gifu Dental Society","volume":"16 1","pages":"121-46"},"PeriodicalIF":0.0,"publicationDate":"1989-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13779024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
