(a) Access to the apical region obtained through the design of a cortical plate (upper left) that could be repositioned without any interference. The SALs preparation at different stages (Table 1; 1 = no lesion; 2 = 50% of the bur diameter in cancellous bone; 3 = 100% of the bur diameter in cancellous bone; 4 = complete cancellous bone width; 5 = cortical bone perforated) can be observed from specimens one (no lesion) to five. (b) Access to the apical region obtained through the design of a cortical plate (upper left) that could be repositioned without any interference. The SALs preparation at different stages (Table 1; 1 = no lesion; 2 = 30% of the bur diameter in cancellous bone; 3 = 50% of the bur diameter in cancellous bone; 4 = 100% of the bur diameter in cancellous bone; 5 = complete cancellous bone width) can be observed from specimens one (no lesion) to five.
