There is provided a scan post for a system of planning and producing oral or maxillofacial restorative products. The scan post comprises a body made of titanium or stainless steel, and at least a portion of the surface of the body is surface-treated using the following steps: sand blasting the treated surface to obtain surface roughness Ra of about 1.5um - 2.5um, and coating the treated surface using Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD) process. The coating deposits on the treated surface a layer of one from the group consisting of chrome, chrome-nityrtide, aluminum nitride and titanium nitride. The surface treating may include after the step of sand blasting and before the step of coating, an intermediate step of rinsing the body with acid to remove sand leftovers from the scan post. |
