Effect of a tunnel-structured beta-tricalcium phosphate graft material on periodontal regeneration: a pilot study in a canine one-wall intrabony defect model

摘要

Background and ObjectiveTissue regeneration is affected by the porosity, chemical properties and geometric structure of graft materials. Regeneration of severe periodontal defects, such as one-wall intrabony defects, is difficult because of reduced tissue support, and bone grafts are commonly used in such cases. In the present study, a tunnel-structured -tricalcium phosphate (tunnel -TCP) graft material designed to stimulate bone formation was fabricated. The objective of this pilot study was to evaluate the effect of this graft material on periodontal regeneration in one-wall intrabony defects in dogs.
