OBJECTIVE This study was undertaken to compare the relative rates and extent of osseointegration of dental implants when placed simultaneously with either corticocancellous block or particulate corticocancellous bone grafts. METHODS Using the canine ilium as a model site, the implants were placed so that each served as its own control. The implants were harvested at 1, 2, or 3 months for evaluation by light microscopy, microradiography, and histomorphometry. RESULTS Both types of grafts were determined to be viable by microscopic evaluation of fluorescent labels. Qualitatively there appeared to be greater bone density in the corticocancellous block graft implant sites. At 3 months, the block graft implant sites had a level of osseointegration (59.6%) that approximated the control implant sites (65.2%), but was significantly greater than the particulate graft sites (39.2%). CONCLUSIONS These results indicate that implants in corticocancellous block grafts develop osseointegration more rapidly than those in particulate bone grafts. The clinical implications of these findings are discussed.

D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog
D005453	Fluorescence	The property of emitting radiation while being irradiated. The radiation emitted is usually of longer wavelength than that incident or absorbed, e.g., a substance can be irradiated with invisible radiation and emit visible light. X-ray fluorescence is used in diagnosis.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
