ASSOCIATION BETWEEN POSTURAL ALTERATIONS AND PACIENTS WITH OCLUSION PROBLEMS WITH SIGNALS ANS SIMPTHOMS OF TMD

Abstract

Introduction: The body functions as a linked set conected for an aponeurotic tissue, where the change of a segment can generate the modification in several other parts of the body. Alterations in inferior members affect the occlusion force, and the mastigatory muscles influence in the posture and stability of the body. Alterations provoked in the occlusion can generate changes in the stomatognathic system, modifying its its function, as well as modifying the position of the body. However there is controversies in literature in relation to this association (position and stomatognathic system), mainly when related to patients with temporomandibular disfunction. Objective: The objective of this study was to verify the immediate effect of an intervention in the occlusion in pacients suffering or not from TMD. Methodology: the study is analytical clinical assay of immediate effect. The population was composed from individuals that were taken care in the post of PSF of the Candeal community (Salvador-Ba) and the dental clinic of EBMSP. The individuals were divided in two groups (with signals and symptoms of TMD and another one without TMD). Alterations in the position in the decurrent plans sagittal and frontal of the modification of the occlusion (of the right, left side and later on both sides) through photographs and of the test of flexion in foot had been evaluated, to evaluate the length of the posterior muscular chain. Results: 71 individuals participated of the study. 34 individuals composed the TMD group. It did not have significant difference for the position comparing the two groups, however the group with TMD presented a bigger prevalence for anterior translation of the body (TMD: 67.6% and without TMD: 46%) and shortening of posterior chain (TFE in group with TMD: 11,07±9,97 and without TMD: 14,46±9,3). Difference was found significant (p<0,05) beetwen before and after the alteration (right, left and both), in the two groups. It had a bigger prevalence of the feminine sex (52%) in group TMD. When carrying through the alteration of the occlusion, the head twirled for the modified side, inclining for the opposit side. Conclusion: Association between the postural change and the modification of the occlusion between individuals with and without alteration in the TMJ was found.
