Influencia de la Oclusión en el alineamiento de las vértebras cervicales con relación al plano Silla-Nasiun

Abstract

This research has studied the effect of occlusion in the cervical alignment of vertebrae with relation to the SN plane, by the use of an oclusal guide. The methodology was explicative, transversal and pre experimental. A study group of 10 university students was the sample, to obtain the data base, we used an oclusal guide for one week and radiographic capture to measure the new position of the first 2 vertebrae; angular and linearly position in relation to the point SN. The results show the angle formed by the axis of the odontoid apophysis (C2) and the plane S-N, which we named angle SN – OR; in habitual occlusion the average is 93,35 ° and in central relation the average of 101,65 °, obtaining a difference of 8,3 ° between both pertaining to the jaw positions. . The linear measurements for the habitual occlusion shows an average distance of 26,1 mm and 18,9 mm for the position in central relation. Existing a difference of 7,2 mm for both pertaining to the jaw positions. As Conclusion: the Occlusion influence in the alignment of the cervical vertebrae with relation to the plane SN
