Manufacture of 3D objects is of most extreme significance in different medical fields counting dentistry. Its appearance started when Charles Hull printed, for the first time, in 1984, a 3D object using the first 3D printer. 3D printing is well gotten by dental experts because of its capability to create complex parts with ease, accuracy, ease of fabricating and decreased chair time permitting the dental practitioner to supply more successful treatment. 3D printing is an additive manufacturing process in which a 3D object is created by the establishment of successive material layers. There are various 3D printing techniques, mainly stereolithography, selective laser sintering, fused deposition modeling in dentistry, which is mainly used in teaching and or managing cases involving implants, different surgeries, periodontal treatment, crowns and bridges, endodontic and orthodontic appliances. This article is focused around the various technologies of additive manufacturing, its developing applications, advantages and limitations in the field of dentistry.
