3d Printing: Reshaping Dentistry

Abstract

3D printing is one of the immediate emerging and fastest growing trends in medicine and dentistry. In contrast to traditional method of subtractive manufacturing, 3D printing is an additive manufacturing method in which a item is made by laying down successive layer of material. Complex anatomical structures can be printed using high resolution resin with great precision. Commonly used techniques in dentistry are stereolithography, fused deposition modelling, selective laser printing. These techniques are used in orthodontics, cutting guides and drills, implantology. With the advent of 3D imaging and modelling technology there is significantly increased rate of success in implantology and surgery with the use of custom-made drills and guides, there is marked increase in accuracy and quality of work. This review paper includes the various technologies, advances of 3D printing and its dental applications.
