Functionally graded materials: An overview of dental applications

Functionally graded material (FGM) is a smart configuration for designing composite materials to improve their long-term endurance. The main characteristic of an FGM is the gradual variation in composition and microstructure across its dimensions, resulting in enhanced properties. This approach has been applied in several fields of thermal barrier coatings, power industry, biomechanical, automotive, aerospace, mechanical, civil, nuclear, aeronautic, and naval engineering
