Assessing the Amount of Residual Bone after Loss of Teeth through Dental CT for the Needs of Dental Implantology

The rapid development of dental implantology in recent years made the use of CT preoperative study a common practice. The establishment of sufficient amount of residual alveolar bone for the needs of successful osseointegration of endosteal implants is important part of the preoperative study. It is also important for making a final decision whether bone augmentation is really needed when large or complex bone defects are present in the jawbone. After analyzing preoperative Dental CT skenogramms of 292 jaws in our retrospective study, we found that in 48 % of the cases there was a sufficient amount of residual bone, and in 52 % of the cases there was a need for bone augmentation present.
