| Popis: | Introduction: Occlusion is a multidimensional phenomenon of which vertical dimension is an important factor. Maintenance of occlusal harmony along vertical dimension helps in better prognosis of the treatment performed. Along with the stomatognathic system, it has also been found to be beneficial for overall health of the postural muscles. Therefore, co-relation between vertical dimension and postural muscles analysis is significant. Aim/Objectives: To evaluate the effect of the restoration of lost vertical dimension with a permissible splint on posture using photogrammetry and S-EMG. Methods and Material: Fifteen patients were selected according to the inclusion and exclusion criteria for the study. Vertical dimension of rest and occlusion were measured using Niswonger’s technique. Posture was evaluated using photogrammetry and S-EMG. For photogrammetry, CVA angle and Gaze angle were measured using photographs on Kinovea software. The posture was evaluated by measuring the activity of postural muscles, namely Sternocleidomastoid [SCM], upper trapezius and spinous erectae using S-EMG. Permissible splints were constructed at restored vertical relation and given to the patient after occlusal equilibration. 30 days post-restoration, the posture was re-evaluated using same methods. Results: Difference between right and left side reduced from pre to post but was not statistically significant. Relation was found only between right upper trapezius and right spinous erectae and left upper trapezius and left SCM. Conclusion: Posture is affected by a number of factors, one of which happens to be occlusion. This study proved that occlusion does have an effect on body posture and an improvement in occlusion will only aid in improving body posture |
