Abstract
This M.Sc. project was aimed to addressresearch concerning geometrical requirements of dental implants and hypodermic needles. The approach followed in this research was to characterize geometries of biomedical microcomponents resulting in experimental data that will produce further research fields to discover the potential improvements for these subjects. The most relevant features havebeenmeasured by means of 3D-SEM technique and an Infinite Focus instrument, ALICONA. The experimental results werecompared with the ones obtained from a reference stylus instrument, Form TalySurf Series 2 or FTS.For the case of the hypodermic needle’s diameter traceability wasestablished from an uncertainty evaluation performed using a calibrated wire gauge. For the dental implants pitch and depth of threads the measurements done on the FTS reference equipment served to compute their uncertainty evaluation. With the Scanning Probe Imaging Processor software, SPIP,the computations needed to acquire the values of the surface topography parameters selected were done.
