On the other hand, the usability of the AM technology for multiple unit FDPs remains questionable both in accuracy and mechanical stability aspects.Įven though 3D printing offers certain advantages over subtractive manufacturing, namely reduced initial cost of the device and waste material, the possibility of fabricating extended dental appliances such as dental models, as well as fabricating a large number of objects in a shorter time period, The milled computer aided design and computer aided manufacturing (CAD‐CAM) interim fixed dental prosthesis (FDPs) are validated clinical options as they offer adequate accuracy and mechanical stability. Is essential but can be more difficult to achieve for multiple unit restorations. Therefore, adequate 3D adaptation (up to a 125‐µm marginal and internal fit) The fabrication of interim restorations is one of the clinical applications that can benefit the most from the developments in 3D printing technology.Īn interim restoration should offer certain mechanical stability, while maintaining the biological health of the teeth and their surrounding tissues. This results in the creation of new clinical applications of the 3D printed products, thereby increasing demand and ultimately reducing costs of AM. With this expansion, a wider range of three‐dimensional (3D) printers and printable materials are being introduced to the market. Additive manufacturing (AM) is arguably one of the fastest developing technologies with great potential in the restorative/prosthodontic domain.
