A 54-year-old man has poor dentition, including missing tooth of #19 and residual root at #20 (Fig.1).
The socket at #19 appears to have not completely ossified (Fig.1 *, Fig.5 >). Use Magic Split and Magic Expanders to expand the ridge top so that an implant will be placed higher for favorable crown/implant ratio (i.e., to reduce abutment screw loosening).
