Abstract
|
|
|
Purpose: The purpose of this study was to evaluate the histological healing process of 3 different types of xenogenic tooth bone graft material and xenogenic bone graft material.
Methods: Three types of human tooth bone graft material (chips, crowns, and roots) and BioOss (Geistlich Pharma AG, Wolhausen, Switzerland) was filled at the preformed 4 round-shaped calvarial bone defects of beagle dogs. The beagles were sacrificed at 2, 4, 8, and 12 weeks, respectively, for radiological and histological evaluation.
Results: Increased strength and radiopacity were detected in all graft material groups in time-dependent manner. New bone was formed and matured surrounding the graft material histologically. Also, a new bone was directly integrated with graft material.
Conclusion: It was expected that newly developed tooth bone graft material would show good bone healing capacity if it was used as a graft material for the restoration of bony defect.
