Abstract

Background. The problem of restoration the integrity of the dentition after tooth loss remains one of the most problematic dental issues. Мodern dental technologies open a promising direction in its solution, in particular - the method of dental implantation. Objective. The aim of our work was to study the changes that occur in the bone tissue of the mandible after implantation of titanium foam and to determine the effect of shock wave therapy (SWT) on its structure restoration. Methods. The study was performed on 15 adult rabbits aged 6-7 months, weighing 2.5-3 kg. The animals from the experimental groups were implanted with titanium pin, 3 mm long. The pin was implanted under combined anesthesia bilaterally into the body of the mandible. One day after the operation, the animals received SWT 500 pulses with a frequency of 5 Hz and a maximum pressure at the wavefront of 1.2 Bar per implantation site using the device Storz Medical Master Plus MP 100. The animals were removed from the experiment on 15-th day, after which the mandible was disarticulated and radiographically performed. The obtained results were statistically significant. The differences at p<0.05 were considered significant. Results. The results showed that the bone tissue of the jaws during implantation undergoes traumatic injury, the results of which, two weeks after surgery on radiographs we can clearly see a violation of the bone tissue structure and a significant increase in its density. Using the SWT method, we obtained a positive dynamics of bone density after titanium pin implantation and slight Rh-changes in bone structure compared with normal. Conclusion. Аfter implantation with titanium pin the bone density of the rabbit lower jaw body is significantly reduced, X-ray shows the heterogeneity of bone structure, areas of sclerosis are expressed. Shock wave therapy helps to restore the quality of bone tissue, this is confirmed by the fact that the density indicators are close to the norm and X-ray shows some separate small areas of restructuring of bone tissue heterogeneity, mainly due to merging the pattern of the bone trabeculae of the bone cancellous part.
