This review article describes the application and characteristics of certain biomedical materials in orthodontic appliances. The elastic recoil of shape memory polymers, determination of the forces and moments experienced by the brackets and eventually by the tooth, reduction in treatment time by employing self-healing smart brackets and decreased enamel lost during debonding due to usage of biomimetic adhesives such as dihydroxyphenylalanine (DOPA) is discussed. Increased plaque retention and microbial attachment around brackets and teeth is of profound concern and by utilisation of hydrophobic properties of self-cleaning materials, this can be reduced significantly. Implantation of bioresorbable temporary anchorage devices, which resorb once their purpose is accomplished and increasing the concentration of fluoride in the oral environment to counter the deleterious consequences of orthodontic treatment such as white spot lesions and caries, are also discussed brief
