3 歯肉の粘膜骨膜弁剥離後にみる骨膜の新生血管と骨組織修復との微細形態的研究(第495回大阪歯科学会例会)

We performed experimental flap surgery on the maxillary anterior region of beagle dogs to examine how it affected microcirculation, and investigated morphological changes in the microvasculature during the healing process. We observed the gingivo-periosteal vascular plexus histologically using a light microscope and a transmission electron microscope 3, 5, 7, 14, 21 and 28 days after the operation. Scanning electron microscopic examination was also done during the same time period using vascular corrosion cast specimens into which acrylic resin had been injected. Our results showed that vigorous vascularization in the periosteum was important in providing a basis for the healing process after periodontal surgery, and that the gingivo-periosteal vascular plexus contributed to the metabolism involved in repair of periodontal tissue.
