Published: March 1, 2022

Abstract Purpose To evaluate and compare the benefits limitations of additive manufacturing for complete denture fabrication. Methods A PubMed Google Scholar search topics pertaining to dentures was performed. The resulting articles were then divided into allow a narrative review. Discussion Determining how printing compares with conventional milled is critical widespread adoption this fabrication technique. Physical properties, tooth bond strength, base adaptation soft‐liner strength are discussed establish compares. Conclusions Printing offers many advantages over conventionally processed dentures; however, questions need be answered by research. include reduced cost most printers compared milling machines, less material waste, ability print multiple simultaneously, complex designs can fabricated that otherwise could not milled. Current research has shown flexural fracture toughness, color stability, printed when dentures. Print orientation been influence accuracy, surface roughness C. albicans adherence which seen or materials. These factors do represent criticism but rather indicate more new promising Since numerous it likely have significant role in years come as knowledge increases materials/techniques continue advance.
