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

本研究旨在通过NaF-PET描述义齿使用后义齿下方残留牙槽嵴骨代谢的时间过程。三名受试者，谁有一个自由端缺牙下颌骨，用义齿取代缺牙区的牙弓治疗。NaF-PET/CT扫描进行了基线，4-6和13周后使用义齿。感兴趣的体积（VOI）被放置在他们的下颌骨在义齿下方的无牙区。计算VOI的CT值和平均标准化摄取值（SUV）。3名受试者的各VOI的SUV在义齿使用后4-6周显著增加，然后在13周显著降低（P
