An article devoted to the topical problem of studying the microbioccnosis of the mouth during various orthopedic operations is presented, since the percentage of failures in this area of dental interventions is still quite high.
Objective: To study the microbiological landscape of the mouth in individuals with implants without and with platform switching to an abutment.
Material and Methods: The study was carried out on patients at the orthopedic stage of treatment in the Department of Orthopedic Dentistry of the TDSI with installed IM PRO dental implants (Helmut Knigel, Germany) and has an implant-abutment connection system using a fixing screw. All patients w'ere diagnosed with "Partial secondary adentia". All patients were divided into 2 groups: group 1 consisted of 9 patients with an implant-abutment system without platform switching; Group 2 consisted of 10 patients with an clement of platform switching to an abutment. The study was carried out in the dynamics of monitoring patients - before the installation of the orthopedic structure, 3 months and 6 months after the installation of the orthopedic structure.
The material for the microbiological study was a biomatcrial from the soft tissue mucosa around the abutment. The material was placed in vials with Stuart's medium and within no more than 3 hours was transferred to the microbiological laboratory.
Results of the study: the obtained results of the study allow us to conclude that when the platforms are switched to the abutment, a positive microbiocenosis is formed on the implants at the 6th month of using the orthopedic construction, but the value of all the representatives of microorganisms studied remains at high levels. At the same time, the microbial landscape is characterized by the prevalence of stabilizing species (Streptococcus salivarius, Streptococcus sanguis, Corynebacterium spp. ). However, the frequency of such microorganisms uncharacteristic for the oral cavity in the test material as enterobacteria, enterococci, indicate the development of dysbiosis in the area of the implant-gingival contact.
Conclusion: The study of the dynamics of the microbial flora in patients with implants with switching platforms to an abutment relative to the indicators before prosthetics, showed mainly a decrease in the quantitative indicators of representatives of both its stabilizing and aggressive components.
