Abstract
Four bioactive ceramic materials currently recommended for regeneration of osseous tissues in treatment of periodontal disease have been compared with Bioglass® particulates, of equivalent size in two compositions, in a monkey model. Both Bioglass® materials were found to be easily manipulated, were haemostatic and osteoproductive allowing restoration of both alveolar bone and periodontal ligament. Epithelial downgrowth was inhibited and epithelial attachment was close to the preimplantation level. The other materials were slower to act and epithelial downgrowth was to the same level as in unfilled control defects.
