The mandibular kinematics in relation to structural and functional modification of temporomandibular joint.

摘要

The aim of this study was to correlate the possible connections between the statical and dynamical occlusion and the pathology of thetemporomandibular joint (TMJ), masticatory muscles and parafunctions. Materials and methods: 83 subjects, 38,6% males and 61,4% femaleswere included in the study. Initially we noted the presence of parafunction of stomatognatic system. We correlated the anamnestic data with theclinical results obtained after the examination. The clinical examinations were addressed to the TMJ, the jaw muscles and static and dynamicocclusion. Results: The results showed an increased frequency of malocclusion (71,1%)in women (p=0,004). As well, there is an evidence ofan association between active premature contact and temporomandibular dysfunction: joint pain (p = 0.05), unilateral clicking (p = 0.05), andbilateral clicking (p = 0.06). Conclusions: This study showed that dental malocclusion, bruxism and other parafunctions could be consideringfavoring factors in producing of TMJ dysfunction, along with other associated pathologies.
