Research progress of holographic interferometry in oral biomechanics

全息干涉术(HI)主要通过全息图像相干产生干涉条纹以实现对物体运动、形变等的测量,对微小位移敏感度高,可做到非接触、可视化地测量物体表面变化。随着全息技术的不断发展,HI的数字化可对位移、形变等达到定性和定量分析,提高了测量精度,对表面力学变化分析具有更好的指导性。HI在口腔医学领域具有一定的研究基础,主要用于测量分析牙体和周围骨骼的形变、力的传递与耗散、修复体和种植体的稳定性变化等。本文就HI在口腔生物力学领域的研究进展作一综述。

Holographic interferometry is sensitive to micro-displacement,and it can be used to measure the surface changes of an object in a non-contact and visual way. The interference fringes generated through the coherence of holographic images are used to measure the vibration and deformation of the object. With the continuous development of digital holography, the digitized holographic interferometry can be utilized to obtain a qualitative and quantitative analysis on the displacement and deformation,which improves the measurement accuracy and has important guidance on the analysis of surface mechanical changes. Holographic interferometry has some research basis in dentistry,which is mainly used to measure and analyze the deformation of teeth and the surrounding bone,the transmission and dissipation of forces,and the changes in the stability of restorations and implants. The research progress of holographic interferometry in the field of oral biomechanics is reviewed in this article.
