ASSESSMENT OF BONE GRAFTING OF UPPER JAW BY COMBINED BONE GRAFT BY X-RAY EXAMINATION (EXPERIMENTAL RESEARCH)
Abstract
Purpose. Roentgenologic evaluation of the upper jaw bone regeneration after crushed composite osteografting.
Materials and methods. The experimental study was carried out on 20 rabbits with artificial defects of the alveolar upper jaw bone. Animals were divided into 4 groups depending on the defect filling method. Roentgenologic studies of the jaws were carried out by contact method using dental apparatus "Chirana" mode at: KV-30-38; SEK-0,002-0,006; MA-25 on a regular x-ray film
Results and discussion. X-ray study of bone fragments was carried out on the 14th, 30th and 90th days of experiment. In the control group on the 90 day - area of homogeneous had low contrast, by its intensity identical to the mucosal tissues; the defect edges were not clear, vague and jagged; there were no signs of cortical plate formation.
In the 1st and 2nd groups on the 14th day of experiment a rectangular shadow was observed in postoperative defect which had unclear edges with signs of contrast reducing. The 3rd experimental group was characterized by the almost completed filling of the defect with homogeneous veil and the most active processes of demineralization. On the 30 day of experiment in groups 1 and 2 heterogeneity of filled defects and presence of low contrast zones were marked. In the 3rd experimental group active processes of mineralization and almost completed defect filling by newly formed bone tissue were revealed. After 90 days of observation in 1st and 2nd experimental groups it was almost impossible to determine the limits of original defect, but some heterogenity of cortical plate formation at the edges was marked. In the third experimental group it was impossible to define limits of the defect, cortical plate was formed, anatomical shape was completely restored.
Conclusions. Based on X-ray study it was established that the most optimal is application of the proposed composite graft directly into the defect and its covering with demineralized allogenic rib plate. In this case, it was almost impossible to reveal the defect area as by the bone structure, and by its shape.
