The purpose of this study was to perform a three-dimensional observation, via microvascular corrosion casts, of the microcirculation system during deposition of cementum after flap surgery and to investigate the permeable structure of the vascular endothelium. Two stages of wound healing after flap surgery were confirmed based on successive vascular changes. The transition between these stages occurred 3 weeks after surgery, at which time new blood vessels disappeared and an early stage of accumulation of new cementum was apparent.

Thus, we investigated bone remodeling in the healing process after mucoperiosteal flap surgery, focusing our attention on the microcirculation.
Methods: Mucoperiosteal flap surgery was performed on 12 adult beagle dogs.
Background: An increase in blood flow from the periosteum after mucoperiosteal flap surgery is essential for healing and angiogenesis and repair may work in close cooperation to facilitate this process. To investigate the role of the periosteal vascular plexus in the healing process, we used 3-dimensional (3-D) and ultrastructural monitoring of the angiogenic process after elevation of the mucoperiosteal flap.
Methods: Mucoperiosteal flap surgery was performed on nine adult beagle dogs.
Background: When the mucoperiosteal flap is elevated, the gingivo-periosteal vascular plexus and periodontal ligament (PDL) vascular plexus sever their connection with the circulatory tracts that pass through alveolar bone. We studied the effect exerted on the PDL vascular plexus during restoration of the circulatory tract.
Methods: We performed experimental mucoperiosteal flap surgery in adult beagle dogs.
