目的：目的是探讨骨密度（BMD）的颌骨（下颌骨和上颌骨）和其他骨骼部位之间的关系。此外，还分析了性别、吸烟、无天然牙年限等因素的影响。材料与方法：18例无牙颌患者（9名女性，9名男性），平均年龄67.1岁（sd 12.6）年进行DXA扫描，以评估腰椎和髋关节以及下颌骨的升支、体部和联合以及上颌骨前部的BMD。升支的BMD值与股骨相似，但显著低于腰椎。体部和下颌前部的值高于股骨和升支，上颌前部的值低于股骨和升支。支骨密度与脊柱和髋关节骨密度标准测量值有中等程度的相关性，但颌骨其他区域的骨密度与骨骼部位无相关性。随着年龄的增长，髋部和升支的BMD呈负相关。无牙年限和吸烟年限与髋部、脊柱和颌骨骨密度无显著相关性。（207）结论：虽然下颌骨的支可能显示出BMD与骨骼部位的相关性，但可以放置种植体的颌骨区域则没有。DXA测量的颌骨骨密度与无牙颌年限、吸烟年限均无相关性。
Objectives: The aim was to investigate the relationship between bone mineral density (BMD) of the jaws (mandible and maxilla) and other skeletal sites. In addition, the influence of gender, smoking and the number of years without natural teeth were examined.Materials and methods: 18 edentulous patients (9 females, 9 males) with a mean age of 67.1 (sd 12.6) years had DXA scans to assess the BMD of the lumbar spine and hip, together with the ramus, body and symphysis of the mandible and the anterior of the maxilla.Results: BMD values for the ramus were similar to those for the femur but significantly lower than the lumbar spine. The body and anterior mandible had higher values and the anterior maxilla lower values than both the femur and ramus. The ramus BMD showed moderately strong relationships with the standard measures of BMD in the spine and hip, but the BMD of other areas of the jaws showed no relationship with skeletal sites. The BMD for both the hip and the ramus showed an inverse relationship with increasing age. There was no statistically significant relationship between BMD of hip, spine and jaw and either years edentulous or cigarette years. (207)Conclusions: Although the ramus of the mandible may show correlation of BMD with skeletal sites, the areas of the jaws where implants may be placed do not. Therefore BMD of the skeletal sites could not be used to predict BMD of the jaws.The BMD of the jaws as measured by DXA showed no relationship with either years edentulous or cigarette smoking.
