Gray scale values. a. Gray scale values at the sites 1 mm, 3 mm, and 5 mm immediately above the maxillary bone augmentation. At 6 months postoperatively, gray scale values at all measurement sites were significantly higher in the group that received bone substitutes mixed with adipose stem cells (ASCs+ group) than in the ASCs+ group immediately after the operation (0 months) and at all postoperative measurement time points in the group that received bone substitutes alone (ASCs− group) (**P < 0.01). b Gray scale values at the sites 1 mm, 3 mm, and 5 mm immediately above the mandibular bone augmentation. At 6 months postoperatively, gray scale values at all measurement sites were significantly higher in the group that received bone substitutes mixed with adipose stem cells (ASCs+ group) than in the ASCs+ group immediately after the operation (0 months) and at all postoperative measurement time points in the group that received bone substitutes alone (ASCs− group) (**P < 0.01). ASCs+, bone substitutes mixed with adipose stem cells; ASCs−, bone substitutes without adipose stem cells; GS, gray scale
