3D PRINTING IN DENTISTRY and DIGITAL IMPRESSION Dr. Claudine E. Lagman ¡ It is the process in which multiple layers of material are added one by one under computer control to create threedimensional object. 3D printing is also known as: Layered Manufacturing Additive manufacturing Rapid prototyping Solid free form fabrication ¡ In 1984, Charles Hull an American Engineer, developed the world’s first working 3-D printer.

Conventional impression Disadvantages ØErrors in tray selection ØInadequate adhesive application ØGag reflex ØShort working time ØTearing and deformation ØRequired Disinfection ØStorage space ØLoss or damage ADVANTAGES of Scanners Elimination of the shortcomings associated with traditional, technique-sensitive impression taking Material Presence of undercuts Material shrinkage Time to casting Impression storage Temperature sensitivity Mixing of impression material Improved diagnosis and treatment planning Faster records submission Fewer retakes Reduced chair time Standardization of office procedures Reduced storage requirements Faster laboratory return Improved appliance accuracy Enhanced workflow CAD/CAM technology Alginate impression Bite registration Plaster cast model Digital 3D models PRE-REQUISITE OF DIGITAL IMAGING DIGITAL SCANNER SOFTWARE to Create Image (CAD CAM system) MILLING UNIT CONCLUSION With the numerous advantages of digital impressions over traditional impressions and the ability to benefit from digital impression taking and/or CAD/CAM,more dentist is using scanners. It will be a routine procedure in most dental offices in the near future.
