ABSTRACTBackground: literature shows researches that has related the curve of Spee to the anterior wall of the glenoid cavity in a proportional way.
Objective: to investigate if there is a direct proportional relation between the depth of the curve of Spee and the angle of the anterior wall of glenoid cavity by means of the cone beam computerized axial tomography.
Method: a hundred and ten 3D scan of patients were studied with a complete dental formula in the lower area, at least in one side. The angle of the anterior wall of the glenoid cavity and the depth of the curve of Spee were measured by using a computational program.
Results: the global measuring of the sides showed that in the right side there was a statistically significant proportional correlation among the studied variables. On the other hand, in the left side the correlation was not statistically significant. When making the analysis regarding sex, a statistically significant correlation was found in the left side in men; and in the right side in women. Regarding age, a statistically significant correlation in an age range of 50 years and more was found.
Conclusions: there was not a direct proportional relation between the depth of the curve of Spee and the angle of the anterior wall of the glenoid cavity due to the great variability in a single patient; likewise, neither sex nor age have a significant effect on these variables.
