Measurement of pressure distribution using tactile sensor and observation of bone metabolic activity using NaF-PET/CT under denture base in vivo

To examine how denture insertion influenced the bone metabolism at the residual ridge beneath the denture, Fluorine-18 NaF positron-emission tomography (PET)and computed tomography (CT)images were taken at baseline, 4-6 weeks, and 13 weeks after the denture use. Although CT value at bone beneath denture did not change, PET standardized uptake value increased during the 4-6 weeks after the denture insertion and then decreased despite no clinical complications in the denture-supporting tissues. This result indicates that wearing of a well adapted denture initially increases bone metabolism beneath the denture and then decreased at around 13 weeks after the denture use without bone structural change which clinical X-ray can detect.
