Abstract

Nowadays dental implants are the number one type of intrusion aimed to restore the integrity of a dentition. That is why deep understanding of peculiarities and patterns of bone tissue structural changes of alveolar part of the lower jaw after a dental implant installation and before its post-traumatic regeneration could become a solid theoretical base for the development of its preventative methodology, early complications diagnostic, and their efficient correction. Purpose. Investigation of changes in bone tissue of alveolar part of the lower jaw 15 days after a surgical dental implant installation. Methods. Research was done on 20 adult 6–7-month-old rabbits, having 2.5-3 kg weight, which were segregated into experimental and control groups with 10 animals in each group. Animals in experimental group where bilaterally implanted with 3 mm titanium pin into a lower jaw tissue under combined anesthesia. After 15 days animals were were taken out of the experiment, and were subjected to lower jaw disarticulation. Bone tissue structure was then studied by X-rays and lower jaw slides. Jaw X-rays were performed on Siemens dental radiovisography instrument with Trophy Radiology software. Bone tissue slides of 0.03 mm thickness were prepared in frontal, sagittal, horizontal and inclined planes, and were studied with Ulab XSP-137TLED microscope using 100-400magnitudes, and captured with XCAM 1080P camera. Results and conclusion. X-rays taken after 15 days from titanium pin implantation showed inhomogeneous structure bone tissue with sclerotic lesions in surgical intrusion zone. There were plots of bone damage, detritus accumulation, jaw bone trabeculae destruction, and osteone bone layer discomplexation at the slides around titanium pin. We also have visualized fibrin aggregation, demineralized bone matrix and lysis zones with fibroid structure at adjacent to implant areas.
