Three-dimensional digital data obtained by laser scanner, computer tomography or digital cameras has been used in dentistry since the early 1990s. In the field of maxillofacial prosthodontics, 3D technologies with sophisticated computer software have been used for simulation and fabrication of prostheses. Although 3D technologies have many advantages over conventional methods, there are still some limiting factors which affect accuracy in particular. This review discusses the advantages and limiting factors of 3D technologies related to maxillofacial prostheses.
