Surface topology and chemical composition are two factors affecting the osseointegration of an implant, extremely relevant to satisfy all the requirements needed for bio-implant applications. Nevertheless, some of the materials used for implants do not satisfy properties such as biocompatibility and osteointegration. In this sense, lasers are adequate tools to produce macro- and micro-structures on metallic alloys or polymer surfaces in order to improve their biological response. In view of this, the process of laser surface texturing of two common materials used in implants, such as titanium and PEEK (polyetheretherketone) is investigated in the present work, both from a theoretical and experimental point of view. In order to perform this process, influence of different laser wavelengths has also been studied (λ = 10600, 1064, 532, and 355 nm).
