In this study, to prevent the induction of functional problems in the mandibular joint and to improve mandibular deformity, we used different osteotomy methods in the left and right mandibular ramus, i.e., intraoral vertical ramus osteotomy in the left side and sagittal splitting ramus osteotomy in the right side. Improvement of mandibular protrusion and normal occlusion were obtained by surgical orthodontic treatment, but the mandibular asymmetry could not be improved. From experience of the reconstruction of malocclusion in jaw deformity, development of the following methods was considered necessary based on problems in orthodontic treatment and future prospects: 1. Diagnostic method by highly accurate and high-dimensional imaging, 2. Biomechanical analysis and a simulation method in each patient, 3. Genetic diagnosis method, 4. Development and improvement of orthodontic devices for the efficient movement of teeth.","PeriodicalId":232357,"journal":{"name":"The Journal of clinical dentistry","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116105842","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}

Producing favorable stress redistributions in the abutments and surrounding tissues is difficult. Various retainer designs have been developed to address this issue. The purpose of this study was to investigate the stress redistribution in the abutments and surrounding tissues of three retainers device configurations based on the RPI system, Konus Krone system, and Bracing arm system using quasi three-dimensional photoelastic methods. Three composite photoelastic models were made of a mandible unilaterally edentulous distal to the right second premolars. Individual simulant materials were used for tooth structure, periodontal ligament, and alveolar bone. Three normal periodontal conditions of the right first and second premolar abutment teeth were considered, and three retainers were cast for the teeth. Unilateral partial dentures with various retainer designs, RPI system, Konus Krone system and Bracing arm system were made for the three models. Simulated vertical and lateral occlusal loads were applied to the dentures, and the stresses which developed in the supporting structures were monitored photoelastically. Under comparable loading conditions, stress redistribution patterns in the abutments and surrounding tissues differed between the three systems, and The RPI system configurations showed the most uniform redistributions across loads directed in all five directions, while Konus Crone systems showed strongly stress redistribution for vertically, posteriorly, and buccally directed loads and Bracing arms configurations showed strongly stress redistribution for anteriorly and lingually directed loads. The results of this study demonstrated that the condition of vertical axis's angle, contact position and contact area of between abutments and retainers has considerable influence on favorable stress distribution.","PeriodicalId":232357,"journal":{"name":"The Journal of clinical dentistry","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129774271","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}

But future dentistry won't be just confined in the tooth and the periodontium and it will be responsible for the diagnosis, prevention and treatment of the disease which occurs in the mouth, jaw and face. Although Temporomandibular Disorders (TMD) is one of those diseases, there are many possibilities in the disease which cause a pain in the orofacial structures. The pain in daily dental practice is usually caused by teeth, oral mucosa, temporomandibular joints and/or masticatory muscles; however, another organ can become a source of occurrence of the pain too. Therefore, it is essential to verify which organ a pain appears from first, in other words a differential diagnosis becomes very important. It is explained how you should differentiate TMD from the pain which occurs in other orofacial structures.","PeriodicalId":232357,"journal":{"name":"The Journal of clinical dentistry","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125460106","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}
