Abstract

ALVES, N et al. Assessment of TMJ Condylar Position and Joint Space in Chilean Individuals with Temporomandibular Disorders. Int. J. Morphol. [online]. 2014, vol.32, n.1, pp.32-35. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022014000100006.

The importance of the condyle-fossa relationship in the temporomandibular joint (TMJ) is not yet fully clear, however, some authors associate the non-central position of the head of the mandible in the mandibular fossa with temporomandibular disorder (TMD). Furthermore, other authors suggest that assessment of joint space is a diagnostic tool for assessing the TMJ alterations. The aim of this study was to evaluate the TMJ condylar position and joint space in Chilean individuals with TMD using cone-beam computed tomography. We selected 19 patients of "Unidad de Trastornos Cráneo Cervico Mandibulares (UCRACEM) - Universidad de Talca, Chile", who had a diagnosis of TMD according to the Research Diagnostic Criteria for Temporomandibular Disorders. The assessment of condylar position was performed using Pullinger & Hollender technique and to evaluate the anterior joint space (AJS), superior joint space (SJS) and posterior joint space (PJS) was used Ikeda & Kawamura technique. Posterior condylar position was found in 39.47% of condyles, central condylar position in 34.21% and anterior condylar position in 26.31%. To condyles in central position we found: AJS = 1.57 mm; SJS = 2.20 mm; PJS = 1.54 mm. To condyles in posterior position we found: AJS = 2.18 mm; SJS = 2.02 mm; PJS = 0.98 mm. To condyles in anterior position we found: AJS = 1.00 mm; SJS = 1.89 mm and PJS = 2.07 mm. We conclude that individuals diagnosed with TMD present anatomical regions predisposing to joint disorders with joint spaces diminished when compared with asymptomatic subjects. Furthermore, the posterior condylar position was the most common in individuals with TMD, however there was great variability in condylar position, therefore we suggest that a non-centralized position of the condyle is not necessarily associated with the presence of TMD. We further conclude that in individuals with TMD the condyles located in central and posterior position present EAP decreased compared with healthy individuals.
