Abstract

Objective: To evaluate the effects of BMP on the repair of animal periodontal defects by using GTR technique.

Methods: 30 experimental mandibular buccal alveolar periodontal defects were produced surgically around premolar and molar teeth in 8 young mongrel dogs. The exposed root surfaces were curetted to remove the periodontal ligament and the cementum. The defects were devided into 3 equal groups (collagen, collagen + BMP, control). The results were examined histologically 1 month and 3 months respectively.

Results: In experimental groups the JE downgrowth was inhibital in the early healing, and the new attachment formation was promoted while comparing with the controls. Compound membrane (with BMP) showed the capacity to support more new bone and cementum formation than the other two groups.

Conclusion: It is suggested that exogenous BMP can be used in GTR technique to promote periodontal regeneration.
