The computer-aided design/computer-aided manufacturing (CAD/CAM) systems were introduced into dentistry in 1970s. This technology has evolved rapidly that, starting from a single crown to full mouth, rehabilitation is possible in a single day now. This article reviews the history, evolution, components, and various materials used for fabrication of prosthesis. It also evaluates popular CAD/CAM systems, its limitations, future evolvement, and also the dental considerations while using them.

“…The 3D systems and printers use a UV lamp or a light source to harden the resin or wax after each layer is jetted. (1,6) Advantages are this technology is fast and cost effective, resolution is high, high-quality finish is possible. Disadvantages are tenacious support material can be difficult to remove completely, support material may cause skin irritation, cannot be heat sterilised, materials cost is high.…”

Abstract3D printing has been acclaimed as a disruptive technology which will change manufacturing. This technology is used in vari ous fields such as aerospace, defense, art. Recently it has become a subject of great interest in virtual surgical planning. The techn ology has a particular resonance with dentistry. It has become of great importance with advancement in 3D imaging and modellin g technologies such as CBCT, intraoral scanning and CAD CAM in dentistry. Uses of 3D printing include the production of drill guides for dental implants, the production of physical models for prosthodontics, orthodontics and surgery, the manufacture of de ntal, craniomaxillofacial and orthopedic implants and the fabrication of copings and frameworks for implant and dental restoratio ns. This paper reviews the types of 3D printing technologies available and their various applications in dentistry and in maxillofac ial surgery.Keywords: Three-dimensional printing, Rapid additive manufacturing, Selective laser sintering, Stereo lithography Introduction3D printing is also known as additive manufacturin g (AM), rapid prototyping, layered manufacturing or sol id free form fabrication. It is the process in which multi ple layers of material is added one by one under comput er control to create three-dimensional object. The key id ea of this innovative method is that the three dimension al model is sliced into many thin layers and the manufac turing equipment uses this geometric data to build each layer sequentially until final desired product is complete d. It all starts with creation of a virtual design of the obj ect. Scanner may be used to scan buildings, rock format ions, etc., to produce a 3D model. The 3D model is slice d and then it is ready to feed into the 3D printer of comp atible brand and type. This can be done via USB, SD or Wi-Fi. When a file is uploaded in a 3D printer, the obje ct is ready to be 3D printed layer by layer. The 3D print er reads every slice (2D image) and creates a three dime nsional object. Objects of any geometry can be made by this technology. This is what we call slicing.

“…7 In fused deposition modeling technique, computer-aided design/computer-aided manufacturing models are made using plastic polycarbonate which is laid in a layered fashion from top to bottom. 8 In digital light processing technique which is similar to stereolithography, in contrast to UV radiation visible light is used to cure the resin. 9 Three-dimensional plotting is a recent technology where soft tissue materials like hydrogels (gelatin etc) are used.…”
