Abstract
The article presents the results of a histological study of morphological changes in bone tissue around established dental implants after exposure to low-intensity, low-frequency ultrasound during dental implantation. Histological studies of tibia bone blocks were conducted in three groups of laboratory animals around installed dental implants, which were subjected to different modes of ultrasonic exposure. In the course of studies, it was found that the processes of osseointegration of dental implants in animals of all groups occurred without staging. In the early stages, granulation tissue was formed, which was subsequently replaced by reticulofibrotic bone tissue, and then by more mature lamellar tissue. The timing and degree of bone maturation, as well as the indicators of osseointegration in groups using low-intensity pulsed ultrasound and without it, were significantly different. It was shown that the ultrasound effect on peri-implant tissues induces osteoreparative processes, stimulating neoangiogenesis in granulation and newly formed bone tissue. It has been established that ultrasonic exposure of implants, and then peri-implant tissues during dental implantation, promotes the formation of bone tissue, the histostructure of which is similar to the histostructure of the maternal bone at earlier stages.
