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.

为了解义齿植入对义齿下残留牙槽骨代谢的影响，在义齿使用后4~6周和13周分别进行18NaF正电子发射断层扫描(PET)和计算机断层扫描(CT)检查。虽然义齿下骨的CT值没有变化，但PET标准化摄取值在义齿植入后4~6周内增加，然后下降，尽管义齿支持组织没有临床并发症。这一结果表明，佩戴适合性良好的义齿最初会增加义齿下的骨代谢，然后在义齿使用后13周左右降低，临床X线可以检测到骨结构的变化。
