Realisation of micro-speckle patterns for digital image correlation on dental implants

In vitro experiments and finite element analyses can be used to investigate the mechanicalperformance of dental implant structures. But before experimental and mechanical evaluations can becarried out, the right material properties, test methods and measurement techniques should be pointed out.The material properties of dental implants and characteristics of the jaw bone are widely documented.Concerning the right experimental setup and measurement techniques no conclusive description is given.Digital Image Correlation (DIC) is currently a widespread method. It uses random speckle patterns that arecorrelated to accurately measure displacement and strains of 3D-structures. If accurate results arepursued, first a thorough optimisation of this measuring technique must be accomplished. The choices aremade based on the expected effect of load application on a dental implant. In literature the expecteddisplacements are quite small, magnitude 100µm, which requires high accuracy measurements. Thepossibilities of using DIC on micro-scale for titanium components is discussed in this paper.
