3D printing – A paradigm shift in orthodontic appliances and patient care

Some of the rapidly developing technologies in orthodontics are digital imaging, 3-dimensional modeling, and printing. 3-D printing uses a layer-by-layer manufacturing technique to create scaffolds that can be used for many applications. With the advent of digital surface imaging and 3-dimensional prototyping, new avenues for producing physical models have opened. The traditional clinical decision-making process has been revolutionized by the incorporation of 3-D printing which makes it convenient for clinicians to avoid physical model storage areas and better visualization of anatomical structures and treatment planning. This paper presents the advancements in additive manufacturing techniques for customized patient care in Orthodontics including recent advances in printing technology and materials. The potential application of 4D printing as an advanced manufacturing technology and the challenges and future perspectives for additive manufacturing are also highlighted.
