Histomorphometrical analysis of the area of new bone in relation to the total defect area concerning the central as well as the cortical defect zone. In both defect zones the area of new bone was significantly higher in the autograft group (central area of the defect zone: p < 0.001 autograft group versus CPG group, cortical defect zone: p < 0.002 autograft group versus CPG group).
