| Research Abstract |
This study aimed to describe the time course of the bone metabolism at the residual ridge beneath the denture following denture use by NaF-PET. Three subjects, who had a free-end edentulous mandible, were treated with a denture replacing the edentulous region of the dental arch. NaF-PET/CT scanning was performed at baseline, 4-6 and 13 weeks after denture use. A volume of interest (VOI) was placed on their mandibles at the edentulous region beneath the denture. CT value and mean standardized uptake value (SUV) of the VOI were calculated. The SUVs of each VOI significantly increased at 4–6 weeks after denture use and then decreased at 13 weeks in all three subjects (P
