Bone Augmentation with Bioactive Glass in Three Cases of Dental Implant Placement

Abstract

This study reports the clinical use of a bioactive bone graft material, PerioGlas^®, in the treatment of dental extraction sites before dental implant placement, to effect bone regeneration and to give early fixation to the implant.

PerioGlas^®, granules, ranging from 90 to 710 mm, are implanted after tooth extraction in three patients; after 6 months bone biopsies were performed in the site of the glass implantation and observed under Electron Scanning Microscopy.

All the granules showed a biodegradation involving precipitation of calcium phosphate that worked as a scaffold for osteoblasts colonization. All cases examined showed the bioactivity of PerioGlas^® granules resulting in new bone formation and biodegradation of the glass. After a two-year clinical follow-up all the implants were successfully loaded and appeared stable.
