Experimental analyses of surface treatment on titanium samples.

The roughness of the dental implant surface will influence the behavior of osteoblastic cells regarding the spread, proliferation, differentiation and synthesis of proteins on the surface of titanium. Depending on its characteristics, roughness can be macro-, micro- and nano-roughness Material and method. We achieved the obtaining of thin layers of biomaterials by the pulsed laser deposition method (PLD, Pulsed Laser Deposition) on the titanium samples and the deposition has been made by Spin coating method of a thin film based on hydroxyapatite, respectively hydroxyapatite-maleic copolymer, only on one side of the sample. Results. From a microscopic point of view, the qualities of bio-glass are remarkable. Thus, bio-glasses are amorphous materials and are successfully used as covering material for metallic and polymeric implants, to significantly increase their biocompatibility. Discussion. The biological properties of the materials for implants are of fundamental importance for the success of the treatments and they are reflected along with other characteristics of the implants, in the tissue reaction they cause under the conditions of their insertion in biological systems. Conclusion. Osseointegration could be impaired in people with diabetes, osteoporosis, with bone metabolism disorder where therapeutic success depends on the biomimetic and functional topography of the dental implant.
