Aim. To increase the efficiency of treatment of patients with dental failure. Material and Methods. Under the supervision were 33 patients aged 21 to 65 years, who had a sinus lift with osteoplastic material and 6 months after dental implantation in the area of bone grafting. In group 1 (17 patients), synthetic osteoplastic material (contains 60% hydroxyapatite, 40% beta-tricalcium phosphate, collagen type 1) was used, in group 2 (16 patients), the bone defect was filled with xenogeneic osteoplastic material (bovine hydroxyapatite). Results and Discussion. All patients had no specifics in the postoperative period. According to CT-scans in patients of 1st group the alveolar jaw bone height before the treatment was an average of 1.61±0.14 mm, in 6 months after the operation was 15.25±0.23 mm. In 2nd group the alveolar bone height before treatment was 1.89±0.13 mm on the average, after the operation was 12.79±0.07 mm. According to the histological study of bone tissue obtained in patients of 1st group, the formation of a newly formed spongy bone was noted mainly at the edges of the biopsy specimen. In the center of the biopsy bone formation is absent. In patients of the 2nd group about 30% of the shear area is occupied by the spongy bone tissue, the rest of the defect is filled with osteoplastic material. Conclusions. A comparative analysis of the use of synthetic and xenogeneic osteoplastic materials after sinus lift has showed almost identical results.
