N2 - Bone implantation with the application of titanium implants became possible afterthe works of Prof. Bra°nemark in the early 1960s, where titanium osseointegrationwas established for the first time [1]. After this discovery, it was found that suchan effect is characteristic not only for titanium but also for zirconium oxide [2], variousalloys [3], hydroxyapatite [4], and other materials. However, despite this, themajority of bone implants are made of titanium and its alloys. This is due to bothbiomedical and mechanical characteristics as well as commercial availability. Morethan 50 years of experience suggests the main feature of titanium osseointegration:the geometric structure of the surface is the most important factor influencing theimplant engraftment along with the chemical composition. This is demonstratedusing the results of both cytological and histological studies [5,6]. In general, themajority of the works describe a positive contribution of the developed surface topographyinto biomedical properties related to the polished titanium [7–9]. However, insome cases insignificant relief modification causes the valuable response of osteoblastsand bone tissue [10]. We try to disclose these relationships based on the worksof our colleagues. Also, in this chapter, we try to analyze the existing techniques ofthe surface geometry modification. Based on the reviewed materials, we will outlinethe prospective of the surface geometry modification of titanium implants withoutchanging the chemical composition of the surface layer for the improvement of theirbiomedical characteristics.
