Three dimensional (3D)-printing allows layer-by-layer deposition of materials to fabricate 3D objects with desired configurations. Not all materials can be printed, but fortunately many of the mineralized materials are among the printable ones. Thus, the field of mineralized tissue in dentistry can greatly benefit from 3D-printing in various aspects including fabrication of mineralized scaffolds and tissues in a customized and controllable manner, with reproducible structure, porosity and pore size. This symposium aims to highlight such benefits and presents the new progress in 3-D printing research which are relevant to treatment, regeneration and repair of mineralized tissue. More specifically the presentation and discussion in this symposium will cover the area in osteoconduction and bone augmentation in relation with 3D-printed designs that mimic the natural bone. In situ printing of composite scaffolds for the treatment of bone defects and 3D-printing of dental implants and biomaterials from research to clinical applications are other subjects of this symposium. 3D-printing may also offer an approach for treatment of mineralized oral critically sized defects, which will be discussed in this symposium.
