Abstract

Abstract: Objective: To compare the efficacy of concentrated growth factor (CGF) gel and CGF extract combined with low replacement rate osteogenic materials for site preservation surgery. Methods: Eighteen patients were randomly divided into two groups. CGF gel group: CGF gel and DBBM were mixed at 1∶1 to fill the bone defect, and CGF extract solution group: the bone defect was filled with the mixture of CGF extract solution and DBBM. Voxel-based superimposition of cone beam computed tomography images were taken before operation, on the same day after operation, and 6 months after operation. Results: From postoperative day to six months after operation, there were significant differences in the mesiodistal height and buccal-lingual height between CGF gel group and CGF extract solution group, and the bone height resorption in CGF gel group was higher than that in CGF extract solution group, but there was no significant difference in mesiodistal width and buccal-lingual width between two groups. Conclusion: The osteogenic effect of CGF extract solution group is better than that of CGF gel group at 6 months after operation.

Key words: site preservation, CBCT, voxel-based superimposition, concentrated growth factor
