Observation of osteogenesis through histological specimens. Hematoxylin-eosin staining and Masson staining of the alveolar bone at 10× and 20× magnification (blue arrow: bone lacuna, yellow arrow: blood vessel, green arrow: muscle fiber, gray arrow: collagen fiber, and black box: the viewing range of the 20× microscope). In hematoxylin-eosin staining, both RG group and Ti-G groups showed a large amount of new bone formation and a large number of bone lacunas. In Masson staining, more blue areas were seen in the Ti-G group than in the RG group, which confirmed that a large number of collagen fibers were formed in the osteogenic space of the Ti-G group
