Influência da relação maxilomandibular, dimensão vertical e contenção posterior na disfunção temporomandibular
This study evaluated the association between maxillomandibular position, vertical dimension and posterior support (CP) with the presence of temporomandibular dysfunction (TMD). A total of 148 patients participated in the study, 78 of whom had a diagnosis of TMD and 70 didn’t present this dysfunction...

| Resumo: | This study evaluated the association between maxillomandibular position, vertical dimension and posterior support (CP) with the presence of temporomandibular dysfunction (TMD). A total of 148 patients participated in the study, 78 of whom had a diagnosis of TMD and 70 didn’t present this dysfunction. The patients were evaluated with regard to the maxillomandibular position, by the Ramfjord frontal manipulation method associated to the deglutition method, it was verified with the carbon paper if it occluded in centric relation (CR) or maximal habitual intercuspation (MHI); The vertical dimension was also evaluated, using the metric method associated to the phonetic; For CP, Individuals were categorized with 0 to 2 occlusal units (OU), 3 to 5 OU (reduced dental arch) and 6 or more OU; And the presence of TMD was evaluated through the Research Diagnostic Criteria for Temporomandibular Disorders (RDC / TMD) . The association between the variables was verified using the chi-square test. When evaluating patients in relation to vertical dimension of occlusion (VDO), it was observed that the majority of patients with this alteration had TMD (52.5%), but the variables alteration of the VDO and presence of TMD were not associated in this study (p=0,495). Regarding the maxillomandibular position, 100% of patients with TMD occluded in MHI, while 95.7% of patients without TMD presented occlusion in MHI. It wasn’t possible to evaluate the association of this factor with TMD. The posterior support variable and the presence of TMD also had no association (p = 0.726 and p = 0.054, for users or not of removable partial denture replacing posterior teeth, respectively). Thus, there was no association between the occlusal parameters evaluated and the presence of TMD, although it was observed that the prevalence of TMD increased as the occlusal support was reduced. |
