Subantral augmentation as a model of studying the opportunities of bone reconstruction with a severe atrophy

Abstract

The alveolar bone restoration is one of the problems of oral surgery, which require solution before dental implantation. Improvement of instruments, development of surgical procedures and creation of new bone substitute materials in recent years have allowed dental implantation in patients with severe bone atrophy in the area without teeth. Nevertheless, developing technologies can not always satisfy the demands of surgeons in selecting the ideal bone substitute material. The aim of the work is to increase the efficiency of bone plasty procedures on the example of the upper jaw. As a study material, three groups of patients with severe alveolar bone atrophy of the upper jaw were selected, who underwent open sinus lifting (Tatum) with various compositions of bone substitute. The article gives examples of a material combinations for obtaining the optimal volume and quality of the restored bone tissue in the region of the maxillary sinus bottom. The article contains a comparative evaluation of the patients treatment results in the observation groups.
