| Research Abstract |
CT and [18F]NaF-PET allowed for a precise estimate of bone metabolism, bone density and trabecular bone structure around the dental implants. Histological deta clearly showed osteogenic reaction around the implants, which related bone metabolism and bone density.
Using [18F]NaF-PET, bone metabolism around the implant could be estimated precisely and three-dimensionally. The result suggests the loading effects in early stage on peri-implant bone formation. Comparing with our previous data using Tc99m-MDP bone-scintigraphy, the results of this study showed different manners of bone-metabolism. Those differences might be due to a difference of uptake mechanisms between 2 tracers, namely 18F- and MDP.
