OBJECTIVES
To investigate the relationship between two-dimensional (2D) and three-dimensional (3D) bone imaging parameters.
STUDY DESIGN
Bone specimens were obtained from the mandibles of five male pigs weighing around 110 kg each. A total of 111 samples were measured two-dimensionally with using solid state digital intraoral radiography. Of these 111 samples, 43 were selected for 3D analysis and measured by microcomputed tomography. Through destructive mechanical testing, strength parameters were obtained.
RESULTS
Correlations between the 2D and 3D parameters were rare; however, both 2D and 3D parameters separately showed significant correlations with strength. Multiple linear regression analyses using both 2D and 3D parameters together showed greater predictability than those using only 2D or only 3D parameters.
CONCLUSION
Architectural parameters in 2D and 3D independently affect trabecular strength; the combination of the two can be used to improve bone strength predictability.
目的
研究二维（2D）和三维（3D）骨成像参数之间的关系。
研究设计
从五只体重约110千克的雄性猪的下颌骨获取骨标本。使用固态数字口腔内放射成像对总共111个样本进行二维测量。在这111个样本中，选取43个进行三维分析，并通过微型计算机断层扫描进行测量。通过破坏性力学测试获得强度参数。
结果
二维和三维参数之间的相关性很少见；然而，二维和三维参数分别与强度显示出显著相关性。同时使用二维和三维参数的多元线性回归分析比仅使用二维或仅使用三维参数的分析显示出更高的预测性。
结论
二维和三维的结构参数独立影响小梁强度；两者结合可用于提高骨强度预测性。
