Empowering Dentistry with additively manufactured magnetic materials: printing techniques, materials, and applications

The manufacture and use of magnetic materials (MMs) in dentistry have spawned new areas of research in the amalgamation of the high-level dental composite framework pursuant to the advent of layer-by layer manufacturing techniques. The proposed research focuses on the most frequently used printing techniques, mainly (i) selective laser melting, (ii), powder bed fusion, (iii) binder jetting, (iv) direct energy deposition(v) electron beam melting materials employed for the fabrication of magnetic materials. The study also provides an extensive discussion of various 3D printable magnetic materials accompanied by the characterization of their magnetic properties. Further, the use of these additively manufactured magnetic materials in the fabrication of magnetic dental prosthetics, magnetic guided orthodontic aligners, magnetic attachment systems for implant supported prostheses etc, are also discussed. Prospects and prevailing challenges are also discussed.
