A review on optical methods to assess dental behavior under stress

摘要

This paper proposes a review of the different opportunities described in literature for quantitative assessment of naturaland reconstructed teeth using optical methods. These experimental method are particularly interesting for understandingthe behavior of the natural tooth, but even more so for the CAD/CAM (Computerized aided design and computerizedaided manufacturing) bonded ceramics reconstructions. Indeed CAD/CAM ceramics are increasingly used as therapeuticoptions. However, little is known about their mechanical behavior under stress, as the response of the prepared toothsupporting it. In the past years, optical approaches were proposed to get whole field and quantitative measurement oftheir mechanical properties. This paper discusses the main methods described in literature, as photo elasticity, digitalMoiré interferometry, speckle interferometry and digital color holography.
