ASSESSMENT OF BONE GRAFTING OF UPPER JAW WITH COMBINED BONE GRAFT BY X-RAY EXAMINATION (CLINICAL RESEARCH)

Abstract

Purpose. Roentgenologic evaluation of the upper jaw bone regeneration after crushed composite osteografting. Materials and methods. Clinical studies were carried on 62 children hospitalized at the Department of Maxillofacial Surgery of the Lviv Regional Hospital with congenital palatal and alveolar clefts. 32 children underwent operations of cleft palate repair (the main group) and 30 ones – mucos-periostal flap plastic surgery by I. Got` and coauthors (the control group). To study the peculiarities of osteografts reorganization roentgenological studies have been carried out before the cleft palate repair surgery and during remote period of monitoring in all patients. Results and discussion. X-ray analysis of the congenital hard palate and alveolar defects after the combined bone reconstruction have shown that transplanted allogenic graft did not cause any complications during its remodeling, and was replaced by newly formed bone, which didn’t differ from the surrounding bone tissue by its structure. Fragments of the upper jaw were reliably fixed into a new position. Conclusions. Based on X-ray exam the research has established that the most optimal one 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 either by the bone structure, or by its shape.
