Recently, more concern has been directed to pen-abutment tissues as they relate to the marginal design of the superstructure, hygiene management, and sequelae of peri-implantitis. Especially, since penabutment tissues lack periodontium, whether or not they play a role as a biological defense mechanism against various external stimuli has been in question. In this study, the microvasculature around implant was investigated.<BR>Titanium screw-type implants were used in this study. Three adult Japanese monkeys were used. At weeks 2, 4, and 8 after the abutment connection, the animals were sacrificed, and microvascular casts were prepared for examination by scanning electron microscopy.<BR>At week 8, as was observed at weeks 2 and 4, the capillary network surrounding the abutment had developed a running horizontal structure and was well defined. At the superior margin of the alveolar bone, the pen-abutment capillary network was anastomosed to the periosteum capillary network. Extension of the pen-abutment capillary network into the alveolar bone surface corresponding to the fixture flange was not observed.<BR>If peri-implantitis exacerbates, or lasts long, due to poor microvascularization lacking periodontal ligament in this region, it is easy for external stimuli to cause damage the alveolar bone. Hygiene control around the implant is more important than around natural teeth.
