3D-printed denture wear patterns

A study examined the wear resistance of additive manufactured, 3D-printed dentures.

In an in vitro study published in The Journal of Prosthetic Dentistry, researchers assessed the linear and volumetric wear resistance of three 3D-printed denture resins compared with conventional double cross-linked polymethyl methacrylate denture materials and tooth enamel following mastication simulation using a biaxial fatigue testing machine.

The researchers found that wear resistance was dependent on the resin used in the 3D-printed dentures. For instance, while one of the resins was found to be comparable to the conventional denture materials, another resin performed poorer than both the conventional denture materials and tooth enamel with regard to linear wear and wear volume.
