SEM findings of patient D showed five different points: (1) at the bone tissue in the apical region of the implant, (2) at the exposed implant surface in the apical region of the implant, (3) at the necrotic bone tissue attached to the implant, (4) at another necrotic bone tissue attached to the implant, and (5) at implant surface near the upper region of the implant by examination under 65 × , 500 × , 1000 × , 2500 × , 5000 × , 10,000 × , and 20,000 × magnifications. Points 1, 2, and 3 showed typical features of MRONJ with concave areas that show bone resorption pits seen on the bone surface of necrotic bone. The attached necrotic bone tissue on the implant surfaces of points 2 and 3 showed a pattern of sclerosing bone with rare signs of bone lacunae
