CM, collagen membrane; 3D-PFTM, three-dimensional preformed Ti-membrane; NBA, new bone area; RBA, remaining graft bone area; BIC, bone-to-implant contact; NB-OB, distance from the upper point of new bone to the old bone; OI-OB, distance from the upper point of the osseointegration to the old bone. The symbol “” indicates statistical significance between the two groups ().
