Biomaterials generally have small sizes and complex structures. Instrumented indentation testing provides accurate measurements even on small samples, minimizing deformation during evaluation and helping identify the relationship between the material's fine structure and its mechanical properties.
Hardness and tensile properties of artificial joint materials, such as titanium alloys, can be measured using instrumented indentation testing to evaluate long-term durability and wear resistance.
Biomaterials for dental implants and prosthetics must withstand various loading conditions within the oral cavity. Instrumented indentation testing can assess the elastic and deformation behavior of biomaterials under real load conditions, helping develop durable and optimal materials for use.
