Postural evaluation of patients with temporomandibular disorders under use of occlusal splints

Abstract

Objectives:Alterations in the temporomandibular complex can reflect in adaptations of the individual's entire muscular system, intervening with the head position and scapular waist, developing postural alterations and modifying all corporal biomechanics. The aim of this study was to evaluate the head position (HP) and head postural alterations before and after installation of occlusal splints.Material and Methods:Twenty patients with temporomandibular disorders (TMD) underwent clinical and postural examination, before the installation of an occlusal splint, and after 1 week and 1 month of use.Results:There were statistically differences for HP, between the initial values and after 1 week of use of the occlusal device (p= 0.048) and also between 1 week and 1 month of evaluation (p= 0.001). Decrease of the painful symptomatology and maintenance of the rectification were also observed.Conclusions:The individual's postural position can suffer biomechanical alterations due to stomatognathic alterations, causing clinically visible changes in dysfunctional individuals and affecting the performance of the involved structures.

Association between temporomandibular disorders and abnormal head postures

“…The same has not been found for other methods, such as the plumb line described by Kendall et al 24 and used also by Saito et al 15 Some studies that used other methods to evaluate FHP, such as the plumb line, but not the craniovertebral angles, have found satisfactory results for the comparison of head posture and TMD. 14,25 No statistically significant differences were found in craniovertebral angles between the SGs and CGs. Similar results were found by Lunes et al 12 who analyzed individuals with the RDC/TMD and measured the craniovertebral angle using a photographic technique.…”

Identification of occlusal prematurity by clinical examination and cone-beam computed tomography

“…Dental professionals must consider the importance of occlusal contacts for the success of dental treatment, maintaining occlusal stability and orofacial harmony, as occlusal interferences may implicate potential damages to the whole stomatognathic system, which includes teeth, supporting structures, neuromuscular system and temporomandibular joints (1)(2)(3)(4)(5)(6).…”

Relação entre idade, gênero, características de maloclusão dental e sintomatologia de patologias funcionais do sistema temporomandibular com aspectos de postura corporal ortostática: implicações fisiopatológicas mútuas

“…Algumas pesquisas relacionaram maior freqüência de alterações na postura corporal de indivíduos portadores de PFSTs quando comparados com indivíduos saudáveis (GELB e BERNSTEIN, 1983;BRAUN, 1991;KRITSINELI e SHIM, 1992;HUGGARE e RAUSTIA, 1992;BERGBREITER, 1993;LEE et al, 1995;ZONNENBERG & VAN MAANEN, 1996;FUENTES et al, 1999;NICOLAKIS et al, 1998;SONNESEN et al, 2001;D'ATTILIO et al, 2004;RIES & BÉRZIN, 2008;STRINI et al, 2009;FLORES et al, 2016), enquanto outras não conseguiram demonstrar qualquer relação (CLARK et al, 1987;DARLOW et al, 1987;HACKNEY, 1993;VISSCHER et al, 2002;MATHEUS, 2005;PERINETTI, 2007;IUNES et al, 2009;MATHEUS et al, 2009).…”

“…Para uma análise mais precisa da vasta literatura científica, esta revisão foi dividida em tópicos, segundo o tipo de proposição do estudo em questão: Tal metodologia foi posteriormente utilizada e adaptada para vários outros estudos que objetivaram avaliar quantitativamente a postura corporal para diversos fins (LUCA, 2002;YI, 2002;ROSÁRIO, 2003;PENHA, 2007;PERILLO et al, 2010 (SONNESEN et al, 2001;VISSCHER et al, 2002;D'ATTILIO et al, 2004;OLIVO et al, 2006;PERINETTI, 2007;PERINETTI & CONTARDO, 2009;PERILLO et al, 2010), quanto nacional 9 (MATHEUS, 2005;MALUF, 2006;MORENO, 2006;BEVILAQUA-GROSSI et al, 2007;RIES & BÉRZIN, 2008;IUNES et al, 2009;MATHEUS et al, 2009;SAITO et al, 2009;STRINI et al, 2009;FARIAS NETO et al, 2010).…”

“…Alguns afirmam haver associações positivas entre postura (de cabeça, coluna cervical ou corporal) e PFST (SONNESEN et al, 2001;D'ATTILIO et al, 2004;RIES & BÉRZIN, 2008;STRINI et al, 2009;SAITO et al, 2009;FARIAS NETO et al, 2010), enquanto outros não conseguiram demonstrar quaisquer diferenças (VISSCHER et al, 2002;PERINETTI, 2007;IUNES et al, 2009;MATHEUS, 2005;MATHEUS et al, 2009 Outros estudos objetivaram verificar possíveis relações entre alterações em oclusão dental e variações posturais, principalmente em cabeça e coluna cervical (FINK et al, 2003;D'ATTILIO et al, 2005;TECCO et al, 2005a;TECCO et al, 2005b;TECCO et al, 2007;MAKOFSKY, 2010;PERILLO et al, 2010;PERINETTI et al, 2010 2) Avaliar a possibilidade e a magnitude de explicação destes aspectos de postura corporal a partir da idade, gênero, características de maloclusão dental e sintomatologias compatíveis com PFST, tomadas isoladamente ou em associação conjunta (Objetivo 2).…”
