In this work the aim is to observe a mechanical characterization study materials for implants, the surface characteristics of the machined test samples of three types of materials used in bone implants for closing five grade titanium, and titanium grade for stainless steel 316 L, there three types of materials are considered as biomaterials because they posses the necessary properties for bone reconstruction, and has proven to be efficient for implants. This study will be through the detailed application of surface characterization and mechanical properties testing. A study of the roughness of the material before implantation and determining the shear modulus and elasticity using a non-destructive method were used. A summary of different types of fasteners and compared to the test results on the materials will be presented. In machined materials dise formats, images were collected on a confocal microscope, and surface analysis was performed for the purpose of obtaining the mean roughness and mean square surface roughness in order to identify the best surface condition.
