Accuracy of fixed implant‐supported dental prostheses additively manufactured by metal, ceramic, or polymer: A systematic review

摘要: Purpose Additive manufacturing (AM) in prosthodontics is used as an alternative to casting or milling. Various techniques and materials are available for the additive manufacturing of the fixed and removable tooth‐supported restorations, but there is a lack of evidence on the accuracy of AM fixed implant‐supported prostheses. Recent studies investigated the accuracy of ceramic AM prostheses. Therefore, the aim of this systematic review was to evaluate the accuracy of additively manufactured metal, ceramic or polymers, and screw‐ or cement‐retained fixed implant‐supported prostheses. Materials and Methods Two calibrated investigators performed an electronic search of relevant publications in the English language following selected PICOS criteria and using a well‐defined search strategy (latest search date—1st of June, 2021). Based on the exclusion criteria (no control group, less than five samples per …
