CBCT STUDY REGARDING THE GAIN OF ALVEOLAR BONE FOLLOWING GUIDED BONE REGENERATION WITH VARIOUS GRAFTING MATERIALS

Abstract

Aim of study. The aim of study was to asses the bone volum gain in guided bone regeneration techniques using various grafting materials. Materials and method. Results. The highest mean values for parameter bone height (11,28 mm), in the alveolar augmentation procedures, were recorded in the study group that combined xenograft Hypro-Oss and PRGF, followed by xenograft SmartBone group (9,83 mm), and allogenuous material OsteoBiol (8,55 mm). The highest mean values for parameter bone width (2,00 mm), in the alveolar augmentation procedures, were recorded in the study group that combined xenograft Hypro-Oss and PRGF, followed by allogenuous material OsteoBiol group (1,96 mm), and xenograft OsteoBiol (1,83 mm). The changes of osteodensity, in the alveolar augmentation procedures, were highest in the xenograft SmartBone group (197,5HU) and allogenuous material OsteoBiol group (180HU), and the lowest osteodensity chages were recorded Hypro-Oss & PRGF test group (151,39HU). Conclusions. The use of the mixed graft Hypro-Oss and PRGF conducted to the highest gain of alveolar bone height and width but the lowest osteodensity values, comparing to xenografts from the new generation of graft materials.
