The present invention provides a porous block for implantation in the maxillofacial area of a human or animal, wherein the porous block:—comprises titanium metal and/or a titanium alloy—has a porosity of at least 40%—is a geometrical structure shaped to fit at least a part of a degraded alveolar process of the human or animal and—as an intended bone contacting surface intended to be in contact with the bone surface of an implantation site in the maxillofacial area of the human or animal, wherein said bone contacting surface has pores extending through the porous block and wherein at least some of these pores have a pore diameter size of at least 50 μm to ensure bone ingrowth and wherein—the porous block is a geometrical structure having a width, a height and a length, said intended bone contacting surface being defined by the width and the length, wherein the average value of the width is in the range of 5-10 mm, the average value of the height is in the range of 3-10 mm and the average value of the length is in the range of 5-100 mm.
