In order to rotate the buccal block easier (Fig.6 pink curved arrow), the apical transverse cut will be wedge in shape (Fig.6 (red), 6' (double lines), 7 (black)). In the 2nd stage, the ridge top split will be extended by using a chisel (Fig.7 longer red line) and the buccal block will be pushed buccally (Fig.8). A guide will be seated to finish osteotomy (Fig.9 white) and implant placement.
