چکیده: (592 مشاهده)
Zirconium oxide has the best mechanical properties compared to other ceramic materials. Modern techniques such as subtractive manufacturing(milling) have acceptable accuracy for restorations. Additive manufacturing (3D printing) has been introduced recently. This new technique has some advantages such as the ability to process complex shapes, optimal use and lower waste of materials. However, the fitness and accuracy of additive manufacturing vs subtractive manufacturing is unclear. The present study aimed to review the accuracy, restorations fit and fracture resistance of printed vs milled zirconia restorations. This systematic review protocol based on PRISMA guidelines. We searched the following databases from 2010 to 2024: Pubmed, Google Scholar, Scopus, Science Direct, Web of Science and Cochrane Library. The inclusion criteria were the Comparative studies that compared milled and 3D printing crowns, studies that clearly reported how restoration fitness was measured, studies that clearly mention the technology and materials. Published works that included veneers, temporary crowns and implant crowns or not mentioned the technology and materials, were excluded. Among 46 related studies, 14 studies most related to our review selected. Three article indicate higher accuracy in printed crowns. however, others show comparable or higher accuracy in milled crowns. Additive manufacturing (AM) has higher internal adaptation. Inaccuracy in horizontal surface of AM is due to layering production. While, 3D printing has best accuracy in vertical surface. Most articles represented that subtractive manufacturing has higher marginal fitness. However, both AM (Additive manufacturing) and SM (subtractive manufacturing) are within acceptable range. Additive manufacturing has acceptable fatigue resistance.
