Rapid Prototyping in Prosthodontics

Rapid prototyping (RP) is a technique of manufacturing parts by the additive layer manufacturing technology; when a three-dimensional (3D) model created in a computer aided design (CAD) system is sectioned into 2D profiles, which are further constructed layer by layer. This technique has been used to build complex three dimensional models in medicine since 1990’s. Based on this principle, the common technologies employed in dentistry are stereolithography (SLA), Inkjet-based system (3D printing-3DP), and selective laser sintering (SLS). Rapid prototyping technology is on its way replacing the traditional long step procedures in prosthetic dentistry, specifically in maxillofacial prosthesis fabrication, implant dentistry, eliminating dependency on artistic skills of dentist and technician and also saves time.
