Computer-aided technology for fabricating complete dentures: Systematic review of historical background, current status, and future perspectives

Use of intraoral digital scanning for a CAD/CAM-fabricated milled bar and superstructure framework for an implant-supported, removable complete dental prosthesis

“…It is difficult to register the dynamic movement of the muscles and jaws with an intraoral scanner. 13 Recently, clinical reports have provided proof of concepts on the application of digital data acquisition for conventional removable partial dental prostheses in Kennedy Class III clinical situations 14 and implant-supported fixed complete dental prostheses 15 in which the dynamic registration of soft tissue was not as critical. In addition to soft tissue registration, scannable impression copings (Scan body; Straumann) can be used in conjunction with the intraoral digital scanner (iTero; Align Technology) to acquire digital data at the implant level in both partially and completely edentulous patients.…”

“…In the long run, digital technologies in complete denture fabrication are expected to help dealing with many other issues such as increased demand, access to care around the world, standardization in clinical research. 85 On the flip side, the costs associated with complete denture fabrication by digital means are still high, as compared to fully analog methods. With widespread acceptance, however, these costs are expected to fall, and likely become lower than expenses associated to the traditional methods.…”

“…85 A survey of U.S. post-doctoral program directors and predoctoral department chairs found that the use of digital technology in denture fabrication is incorporated in more than half of the graduate programs, while only 12% of the surveyed schools observe it in predoctoral education. It is estimated that up to 10% of complete dentures delivered in academic settings are processed by digital means.…”

Complete denture fabrication with CAD/CAM record bases

“…[12][13][14] The bases are milled from prepolymerized acrylic resin cylinders that are highly condensed and less porous than conventional denture acrylic resin. 15 Bidra et al 15 describe the anticipated benefits of the new production process as providing better strength and fit and the potential to harbor fewer microorganisms with fewer resulting infections. This technology provides an interesting possibility in the treatment of patients who are susceptible to oral candidiasis and could be added to the treatment regimens already described.…”
