Radiologic evaluation of reparative osteogenesis in experimental animals during implantation of different compositions of osteoplastic materials

Aim – to study the effectiveness of reparative osteogenesis during the operation of guided bone tissue regeneration using various combinations of osteoplastic materials by cone-beam computed tomography. Material and methods. In experimental animals, various ratios of compositions of autogenous osteoplastic compositions from bone chips of the lower jaw or ilium, xenogenic osteoplastic material and bioresorbable membrane were used. Results. The optical density of the bone regenerate was estimated by computed tomography after the method of guided tissue regeneration. Reparative osteogenesis was studied using various combinations of autogenous bone and xenogenic material. Conclusions. The obtained results allow us to recommend the use of compositions of osteoplastic materials from autogenous bone and xenogenic material for practical use. It has been experimentally proven that high rates of bone tissue regeneration are achieved using a mixture consisting of 25% autogenous bone (angle of mandible, internal mouth cavity of donor) and 75% xenogenic material.
