Purpose This paper aims to improve the efficiency and the quality of metal dental prostheses, reporting on the first patientfitted titanium Ti complete denture base plate fabricated by integrating the technologies of computeraided design and computeraided manufacture CADCAM and laser rapid forming LRF. Designmethodologyapproach To make a complete Ti denture base plate, the traditional lostwaxcasting technique is commonly used in dentistry. In order to simplify this laborintensive process, a new method combined with LRF was invented. Initially, a maxillary edentulous plaster cast was converted to point cloud data by laser scanning system. Subsequently, point cloud data were reconstructed into a 3D solid digital cast, which is stored in standard triangulation language format. Thereafter the 3D denture base was sliced electronically into a sequence of layers defining the regions of the component and, based on it, the complete Ti denture base plate was built layerbylayer using a laser additive manufacturing technology. Findings After CADCAMLRF process, the Ti denture base plate was designed and successfully fabricated layerbylayer. After the traditional dental finishing techniques, the complete Ti denture base plate was made and assessed by clinician and patient. The clinical evaluation on quality of fit was judged to be acceptable. Originalityvalue The CADCAMLRF system is a potential candidate to replace the traditional lostwaxcasting technique and provides a new platform for the design and manufacturing of custommade Ti denture plates and other restorations especially for implant substructure and framework of partial removal of denture.
