Abstract
There is a high level of evidence that survival rates of dental implants placed simultaneously with bone augmentation are similar to survival rates of implants placed into pristine bone. In some prospective studies, the survival rates, after a mean observation period of 12.5 years, for implants either placed simultaneously with guided bone regeneration or placed into native bone were 93% and 95%, respectively, but the studies that evaluated the stability of the augmented bone in the long term are still scarce. Our study was carried out to evaluate the volumetric stability of guided bone regeneration in long term. The stability of Guided Bone Regeneration provides long term security in the aesthetics success of implants placed in these sites The defects evaluated were class 2 and 3. All sites were operated by the same surgeon. Cone beam computed tomography scans were employed to assess the stability of guided bone regeneration in long term. All measurements were performed by a single examiner. The specific measurement program was used ( I-CAT Vision).
