Although temporomandibular joint （TMJ） disk dynamics have been strongly linked to OA and ICR/PCR, and disk displacement can cause facial asymmetry, early detection and prevention of TMJ disk displacement are difficult. Therefore, this study sought to compare the connection between facial asymmetry, mandibular condylar length, and TMJ disk displacement in skeletal Class II patients without condylar head deformity. The study included 33 orthodontic Class II patients without condylar head deformity but did have TMJ symptoms. Those with mandibular deviation were assigned to Group A （Group A-L for long condylar heads and Group A-S for short condylar heads）, while those without were assigned to Group B （Group B-L for long condylar heads and Group B-S for short condylar heads）. Both Groups A and B had a laterality in the length of the condylar head, with the A-S group having a significantly shorter condylar head than the other groups. Severe disk displacement was noticed in 25％ of patients in the A-L group, 40.0％ in the A-S group, 15.4％ in the B-L group, and 15.3％ in the B-S group. Conclusively, even in cases without condylar head deformity or facial asymmetry, 15.3％ of patients had a severe anterior displacement of the TMJ disk, indicating that the degree of disk displacement does not always correlate with the presence or absence of condylar head deformity.","PeriodicalId":23019,"journal":{"name":"The Showa University Journal of Medical Sciences","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135052141","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}

The determination of thickness and evaluation of material properties were conducted before and after thermoforming. 2） We devised three types of holding jigs and conducted compression tests on the aligners’ shape. The apparent elastic modulus of the aligner was compared and examined through the stress–strain diagram. 1） Deformation and variation in thickness were observed following thermoforming; however, the elastic modulus remained constant. No significant differences were observed in the elastic moduli of materials with different thicknesses. 2） The results of mechanical tests on the aligners indicated that the apparent elastic modulus increased with the thickness of the material. There were no variations in the thickness and physical properties of the aligner materials before and after thermoforming; however, as dentition morphology is complex, we assumed that a greater sheet thickness obtained by thermoforming would increase the elastic modulus of the aligner. Aligner holding jigs were developed and used to study the mechanical properties of the aligners. These properties were affected by the shape of the jig’s holding and joint sites as well as the thickness of the thermoplastic material.","PeriodicalId":23019,"journal":{"name":"The Showa University Journal of Medical Sciences","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135008663","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}
