OBJECTIVE
We sought to measure the bone mineral density (BMD) of various regions in the maxilla before implant treatment and to investigate correlations between these values and the BMDs of the spine and hip.
STUDY DESIGN
Eighteen patients were examined by means of quantitative computed tomography, and the BMD of the maxillary alveolar ridge was calculated. The same patients also underwent dual-energy x-ray absorptiometry of the lumbar spine and the total hip. Analysis of variance was used to compare BMD values between and within individuals. The Pearson correlation coefficient was used to correct for sex and body mass and to calculate the correlation between the BMD of the maxillary alveolar ridge and the BMD of the spine and hip.
RESULTS
The maxillary BMD varied significantly between individuals (P <.001) and within individuals (P <.001). The BMD of the anterior region of the maxilla was correlated significantly with the BMD of the lumbar spine (r=0.6; P <.05).
CONCLUSION
A site-specific evaluation of maxillary bone tissue could be of value before implant treatment.
目的
我们试图测量种植治疗前上颌骨不同区域的骨密度（BMD），并研究这些值与脊柱和髋部骨密度之间的相关性。
研究设计
通过定量计算机断层扫描对18例患者进行检查，并计算上颌牙槽嵴的骨密度。这些患者还接受了腰椎和全髋部的双能X线吸收测定法检查。采用方差分析比较个体间和个体内的骨密度值。使用Pearson相关系数校正性别和体重，并计算上颌牙槽嵴骨密度与脊柱和髋部骨密度之间的相关性。
结果
上颌骨骨密度在个体间（P<.001）和个体内（P<.001）均有显著差异。上颌骨前部区域的骨密度与腰椎骨密度显著相关（r = 0.6；P<.05）。
结论
在种植治疗前，对上颌骨组织进行特定部位的评估可能具有重要价值。
