Figures 7–12. Figure 8. Cement-retained abutment. No gaps are present between implant and abutment. The cement fills all the spaces (reflected light microscopy, original magnification ×20). Figure 9. Cement-retained abutment. No spaces are present between implant and abutment. No organic material is present inside the cement (reflected light microscopy, original magnification ×12). Figure 10. Cement-retained abutment. No gaps are present at the apex of the abutment. The cement fills all the spaces. No organic material or bacteria are present (reflected light microscopy, original magnification ×50). Figure 11. Cement-retained abutment. No gaps are present between implant and abutment. The cement fills all the spaces. No cement fractures are present (reflected light microscopy, original magnification ×12). Figure 12. Cement-retained abutment. No biological fluids are present in the cement. The cement fills all the spaces. No cement fractures are present (reflected light microscopy, original magnification ×50)
