Clinical and laboratory study of the effectiveness of composite materials in the fabrication of reinforced composite splints for chronic generalized periodontitis

   Research objective. To carry out a comparative assessment of the effectiveness of using composite materials Estelite ASTERIA and CHARISMA Diamond for the manufacture of reinforced composite splints in chronic generalized periodontitis.

  Materials and methods. Laboratory stage: 10 standard cylindrical samples 2 mm high and 5 mm in diameter made of Estelite ASTERIA and CHARISMA Diamond materials were studied using scanning electron microscopy (SEM). Clinicalstage: 40 patients with a diagnosis of moderate chronic generalized periodontitis K05.31 were treated, and they had I–II degree of tooth mobility. 19 patients in the first group received fixed reinforced composite splinting structures using invasive methods. The method involved placing the liquid composite reinforcement in grooves pre-formed in the hard tissues of the teeth, followed by covering it with a 2 mm layer of Estelite ASTERIA composite material. In the second group, similar structures were made using CHARISMA Diamond material. The patients were monitored for 6 and 12 months, and their шина integrity and aesthetics were evaluated. A SEM study was conducted on the fractured composite material after 12 months of use of the reinforced composite tires.

   Results. A comparative assessment of the condition of reinforced composite tires made of the two materials under study revealed a tendency 12 months after their manufacture to exceed the percentage of cracks (26.3 ± 10.4 and 9.5 ± 6.6 %, respectively, p > 0.05) and chips (15.8 ± 8.6 and 4.8 ± 4.8 %, respectively, p > 0.05) of the composite tire structures in patients of group 1 compared with group 2, and after 18 months there were significant differences between the groups in the number of cracks (57.9 ± 11.6 and 23.8 ± 9.5 %, respectively, p < 0.05).

   Conclusions. Based on the analysis of the results of the laboratory and clinical stages of the study, it can be concluded that the use of the CHARISMA Diamond composite for the production of reinforced composite splints in chronic generalized periodontitis is more appropriate than the use of the Estelite ASTERIA material, due to the lower number of cracks and chips in the structure and the later occurrence of these defects.
