ABSTRACT
The objective of the study was to investigate the morphological features of the temporomandibular joint in adult patients with posterior occlusal plane and different inclinations. Fifty five skeletal I occlusion patients with average were included, shooting CBCT in the intercuspal position, divided into 3 groups according to OPP-FH angle, and measurement of the temporomandibular joint morphology was calculated with cone beam computed tomography (CBCT) special software Invivo 5.0, Statistical analysis of three groups of data using SPSS23.0. The condyle usually locates in the middle of the fossa, the maximum axial area of the condyle (A) was statistically significant between the group 1 and the group 3. The internal and external diameter (MD) of the condyle was statistically significant between group 1 and group 3, and group 2 and group 3. The bilateral TMJ morphological features of the three groups were basically symmetrical. The position of the condyle in the fossa is mostly centered, and some of the posterior, the maximum axial area and the internal and external diameter of the condyle are different in three groups.
RESUMEN
El objetivo de este estudio fue investigar las características morfológicas de la articulación temporomandibular (ATM) en pacientes adultos con plano oclusal posterior y diferentes inclinaciones. Se incluyeron 55 pacientes con oclusión esquelética tipo I, visualizados por tomografía computarizada de haz cónico (CBCT) en posición intercuspiana, y se dividieron en 3 grupos según el ángulo OPP-FH. La medición morfológica de la articulación temporomandibular se calculó con CBCT y mediante el software especial Invivo 5.0. El análisis estadístico de datos se realizó con el software SPSS 23.0. El cóndilo de la mandíbula generalmente se ubica en el centro de la fosa; el área axial máxima del cóndilo de la mandíbula (A) fue estadísticamente significativa entre los grupos 1 y 3. Los datos de los diámetros medial y lateral (DM) del cóndilo de la mandíbula fueron estadísticamente significativos entre los grupos 1 y 3 y los grupos 2 y 3. Las características morfológicas de la ATM de los tres grupos fueron básicamente simétricas. La posición del cóndilo de la mandíbula en la fosa fue principalmente centrada, y parte del área axial máxima, posterior y los diámetros medial y lateral del cóndilo de la mandíbula fueron diferentes en los tres grupos.
