Descrição

The main objective of this study was to investigate if there is a relation between the cortical bone thickness of human mandibles, with age and patient gender. In this work, the measure of the cortical bone thickness was obtained using different medical images. Different human mandibles were obtained, with high resolution, through computed tomography. The cortical thickness was measured using image processing software (Sante DICOM Viewer FREE, Santesoft). The three dimensional visualization of the medical images was obtained using InVesalius 3.0 (FREE Beta 2 Software, C. T. I. Renato Archer). An initial work with this purpose was produced by [Fonseca, et al 2010] using other software. A total of eight medical images were analysed in two different groups. One group was characterized with four female mandibles, from different ages (26-79 years old). Other group with four male mandibles has similar age (42-57 years old). The cortical thickness value was obtained for each studied case. A comparison between gender patients was obtained. Conclusions about the cortical bone thickness of the mandible affected by tooth extraction, age and gender patient will be produced. The use of this type of information could be useful for complementary diagnostic information and clinical treatment planning.
