Assessment of the Quality of Residual Alveolar Bone after Edentulism, Based on Dental CT Imaging for the Needs of Dental Implantology

The rapid development of dental implantology in recent years made the use of CT preoperative study a common part of detailed operational planning. Establishing the quality of residual alveolar bone in the area of interest, for the needs of successful osseointegration of endosteal implants, is an important part of the preoperative study. In the presence of an active bone transformation in the zone of interest, severe osteoporosis zones or such, combining osteoporosis and condensing osteitis, might be present, leading to higher risk of early compromise of endosteal implants. After analyzing preoperative Dental CT skenogramms of 292 jaws in our retrospective study, we found that in 55 % of the cases, the quality of jawbone was appropriate for successful osseointegration process. In 38 % of the cases there were osteolytic bone defects and in 21 % - osteosclerotic condensing osteitis bone defects present in the area of interest.
