Аннотация: In previous experimental investigations, adhesion strength was studied with a static tensile load of dental cement joints of an individual milled transdental implant with hard tissues of the tooth root. At the second stage, the effect of artificially formed roughness of the implant surface on the adhesive properties of the cement joint implant-tooth was studied. The implants were sandblasted with alumina pellets of sizes 50, 150, 250 microns – the artificial roughness was the best when processed with granules of 250 microns. In the present work, the next stage of research is presented – the effect of the thickness of the cement joint “transdental implant - cement - dentin tooth” on its adhesive properties. Before milling samples of transdental implants on a digital model, the intra-root part of the implant was reduced by 20, 50, and 100 μm, sandblasted with alumina powder of 250 μm grain and fixed to a removed tooth on cements that have worked best in previous studies. All tests were carried out on an Instron 5900 experimental setup. Zirconia implants were considered in combination with the two most effective cements Fuji-1 and Multilink-N (with the highest adhesion-strength characteristics). As a result of experiments, the combination of zirconia material with Fuji-1 cement turned out to be much better than with Multilink-N cement. The work carried out computer simulation of the drawing process a prototype of a zirconium implant from a tooth root sample with different thicknesses of cement film 20, 50 and 100 μm. A satisfactory qualitative and quantitative agreement was obtained between the results of three-dimensional numerical analysis and experiment: with a decrease in the thickness of the cement film from 100 μm to 20 μm, an improvement in the properties of the adhesive compound is observed, and a thickness of 50 μm can be considered optimal.
