Implantology, which deals with the method of implanting dental implants in the jaw, is one of the most up-to-date and efficient functions in the world regarding dental treatments, which is rapidly expanding and spreading due to the increase in general growth and progress. Appropriate strength, suitability of biocompatibility, beauty and similarity of titanium implants with natural teeth, as well as the success rate of its implementation by surgeons, have made this method a suitable alternative for missing teeth. One of the important and influential factors on the integration of the implant with the gum bone after the implant work is the quality of its surface in order to increase bone formation between the surface of the dental implant fixture and the gum bone. In this research, the effect of the new combination method of sandblast acid etching with anodizing (SLA with anodizing) on the surfaces of dental implant fixtures has been investigated. In this method, for the sandblasting process, pressure centers and particle spraying angle, and for the washing process, temperatures and acid washing time, and for the anodizing process, voltage and time projects have been considered differently. In this regard, 68 different modes of sandblasting, acid washing and anodizing processes were investigated. For these 68 different states, various tests including: surface roughness, cell viability, elemental and chemical composition analysis, wettability, energy level, hydrogen crispness, checking the amount of sandblast particles stuck on the surface and finally bone formation test were performed in a laboratory environment. . To compare the quality of each of the 68 fixture surface preparation methods. Finally, from these 68 different modes to one mode that has the highest standard conditions in all tests (mode 29) with 4 bar spraying pressure, 30 degrees spraying angle, 75 degrees acid washing temperature, 6 minutes acid washing time, 100 volts anodizing voltage and Anodizing time of 5 minutes was achieved. This condition has a surface roughness of 1.955 micrometers, 92% viable Mann cells, a wetting angle of over 150 degrees, with the lowest pollutant level and accelerated daily bone formation in the early days after treatment compared to others and also the Iranian production sample of Darin Kasht Company. Mana has the best known surface properties. By using artificial neural network training and extracting the results obtained from practical tests of 68 different modes, he predicted two optimal modes, one mode of interpolation between considered modes (ANN-1) and one mode of extrapolation. The considered states (ANN-2) were obtained that the first state increased cell viability up to 93% and the second state increased cell viability up to 94% and its bone formation results are better than other states. is From the comparison and analysis of the present research with the SLA method (without anodizing process), it has been concluded that with the sandblast method, acid etching with anodizing (SLA with anodizing) is a suitable method for titanium engineering level. which structurally accelerated bone bonding compared to other surface preparation methods, including the SLA method, that are used.
