          Abstract

          Las alteraciones de la articulación temporomandibular son frecuentes en la práctica clínica odontológica. Esta disfunción tiene variados factores etiológicos, tales como deficiencia de la oclusión, alteraciones biomecánicas y anatomofisiológicas, entre otras. Evaluamos 20 radiografías panorámicas de mandíbula, de individuos entre 21 y 77 años de edad. Medimos algunos parámetros del proceso condilar y de la rama de la mandíbula. Estudiamos las radiografías en un negatoscopio, efectuándose las medidas con una caliper digital. Se utilizó el programa estadístico SPS 10.0, realizándose un estudio descriptivo piloto. La mayoría de los diámetros del proceso condilar fueron mayores en las mujeres, así el diámetro vertical izquierdo, ( C4), con valores de 19,7 mm en los hombres y 20,3 mm en las mujeres, en cambio, el diámetro vertical (R3) de la rama de la mandíbula fue mayor en los hombres con un valor 43,1 mm y en las mujeres 38,8 mm, en la rama derecha; la rama izquierda tuvo un valor en los hombres de 39,6 mm y 38,6. mm en las mujeres. Estas diferencias podrían causar problemas en la masticación y diferencias en la mordida de los individuos, alterando la biomecánica de la articulación témporomandibular que contribuye a la disfunción y dolor que frecuentemente relatan los individuos

          The temporomandibular dysfunction is common in the odontologic clinic practices. This dysfunction has lot of etiologic factors, like problem of occlusion, biomechanics, anatomical and physiological alterations. 20 panoramic mandibule radiography were evaluated, from people aged between 21 and 77 years old. Some parameters of the condylar process and mandibular ramus were measured . This measure was done with a negatoscopy, and digital calliper. The sample was analyzed with the statistical program (SPPS 10, 0). Most of the diameters of the condylar process were higher in women, thus the left vertical diameter, ( C4), with values of 19.7 mm in men and 20,3 mm in women, on the other hand the vertical diameter (R3), of the mandibular ramus was higher in men with a value of 43,1 mm. and in women was 38,8 mm, in the right ramus; the left ramus had a value of 39,6mm. in men and 38,6mm in women. This difference could cause problems in the mastication and bite of the individuals, producing unbalance in the biomechanics, dysfunction and pain in the temporomandibular joint

              The Orthopantomogram, an aid in diagnosis of temporomandibular joint problems. II. The vertical symmetry.

              Vertical measurements of the Orthopantomograms of 152 patients were made for condylar and rami heights. The symmetry between the right (R) and the left (L) side was calculated with the formula: [(R-L)/(R + L)]. A statistically significant difference between the patients of a routine dental group and the patients treated for craniomandibular disorders was found regarding condylar height symmetry.
