The object of the study there is a level of hyperemia of the mucous membrane around the installed intraosseous dental implants with different coating material according to the results of histogram analysis of digital microscopy. The problem to be solved – evaluation of the degree of hyperemia of the periimplant mucosa around intraosseous dental implants coated with rutile, in comparison with titanium implants of VT-6 alloy after prosthetics. Main scientific results: Analysis of digital images using histogram evaluation of the red component of the spectrum showed that 1 month after prosthetics in group 1, which included 20 patients who had intraosseous implants made of titanium alloy TiV6Al (VT-6), the above indicator increased to 191 (St.Err. 4.45). The difference was 4 conventional units. Similarly, in group 2 (16 people) who had intraosseous zirconium implants, there was an increase in the quantitative rate after prosthetics by 9 conventional units, and its value was 194 conventional units (St.Err. 3.64). Since increasing numerical values and shifting the digital histogram to the right is an objective criterion for reducing the intensity of redness, it can be concluded that there is a reduction of mucosal irritation after orthopedic treatment with a predominance of this process in the group of patients who received intraosseous dental implants coated with rutile. The area of practical use of research results: Since the authors first studied the reaction of the peri-implant mucosa in contact with various implant materials at the stages of orthopedic treatment, this is the basis for the introduction into general medical practice of intraosseous dental implants made in Ukraine using rutile application technology. The area of application of an innovative technological product - it is a dental implant practice. The obtained results will allow to use more widely Ukrainian implants of non-demountable construction with a high level of surface preparation, for the purpose of further orthopedic treatment with the use of non-removable metal-ceramic dentures.

The review analyses the microstructure of the commercial Co–Cr–(Mo, W) dental alloys fabricated by 3D digital selective laser melting (SLM), which is the most promising technique among the emerging additive fabrication technologies used for metal products manufacturing in dentistry. In this regard, the main goal is to compare the microstructures of the metal dental products produced by two currently used technologies, namely, conventional casting and SLM. We consider the latest research published from 2013 to 2022. The microstructures are evaluated using optical microscopy (OM), scanning electron microscopy with energy-dispersive x-ray spectroscopy (SEM–EDS), x-ray diffractometry (XRD), electron backscatter diffraction (EBSD) pattern analysis, and atomic force microscopy (AFM). The microstructure analysis allows concluding whether the SLM fabrication process is suitable for dental applications. As shown, the microstructure of the Co–Cr dental alloys depends on both the chemical composition of the samples and the parameters of the manufacturing technique used. Experimental results have proven that, in contrast to the conventional casting, the SLM-fabricated specimens display superior microstructure due to complete local melting and rapid solidification. Additionally, the SLM process minimizes residual flaws and porosity. As a result, SLM allows producing the dense material comprising homogeneous fine-grain microstructure.
