Abstract
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.
Highlights
Materials and methods The first experimental group included 20 patients who had intraosseous dental implants made of titanium alloy TiV6Al (VT-6)
Since an increase in the mean value of the histogram indicates a decrease in redness, we can conclude that over time, the irritation of the mucous membrane decreases
Comparison of the results of the mean value of the median red colour of the histograms of the microscopy showed that the representatives of the two groups showed an increase in quantitative values
Summary
Orthopedic rehabilitation of patients with dental implants is a common method of eliminating dentition defects [4]. Scientists are actively looking for options to modify the titanium surface using nanotechnology [6]. An example of such an approach is the creation of an oxidized contact layer (rutile), the study of the properties of which is devoted to a large number of scientific publications [7, 8]. Before the start of the research, two statistical hypotheses were formulated: – H0 (null hypothesis) – numerical values based on the results of research in the experimental groups will not have statistical differences. – H1 (alternative hypothesis) – numerical values based on the results of research in the experimental groups will have a statistically significant difference Before the start of the research, two statistical hypotheses were formulated: – H0 (null hypothesis) – numerical values based on the results of research in the experimental groups will not have statistical differences. – H1 (alternative hypothesis) – numerical values based on the results of research in the experimental groups will have a statistically significant difference
