Quantitative ultrasound is used to characterize osseointegration at the bone-implant interface (BII). However, the interaction between an ultrasonic wave and the implant remains poorly understood. Hériveaux, Nguyen, and Haiat [(2018). J. Acoust. Soc. Am. 144, 488-499] recently employed a two-dimensional (2D) model of a rough BII to investigate the sensitivity of the ultrasonic response to osseointegration. The present letter aimed at assessing the validity of the 2D assumption. The values of the reflection coefficient of the BII obtained with two and three-dimensional models were found not to be significantly different for implant roughness lower than 20 μm. 2D modeling is sufficient to describe the interaction between ultrasound and the BII.
定量超声用于描述骨-种植体界面（BII）的骨整合情况。然而，人们对超声波与种植体之间的相互作用仍了解甚少。Hériveaux、Nguyen 和 Haiat[（2018）。J. Acoust. Soc. Am. 144, 488-499]最近采用粗糙 BII 的二维（2D）模型来研究超声响应对骨整合的敏感性。本函旨在评估 2D 假设的有效性。对于粗糙度低于 20μm 的种植体，通过二维和三维模型获得的 BII 反射系数值没有显著差异。二维建模足以描述超声波与 BII 之间的相互作用。
