OBJECTIVE: To study the regeneration of periodontal tissue after the application of beta-TCP/BMP artificial bone to class II furcation defects.
METHODS: Periodontal defects were produced surgically around premolar teeth in 4 dogs. The flap surgery was performed and the root surfaces were curetted to remove the periodontal ligament and the cementum. A synthetic bioabsorble barrier manufactured from poly DL-lactide was used. The defects were divided into 3 groups (beta-TCP/BMP + PDLLA, PDLLA, control). 12 weeks after surgery, the animals were sacrificed and the teeth with their supporting periodontium were processed for light microscopic evaluation.
RESULTS: The definitive evidences of regeneration were founded both in BMP/GTR group and GTR group, but the BMP/GTR group exhibited more new bone formation, cementum deposition occupying the majority of the furcation defects than the other two groups.
CONCLUSION: It was concluded that the beta-TCP/BMP artificial bone can be used in GTR technique to promote periodontal regeneration.
