(Identica Hybrid)		 Wear resistance of the 3D-printed PMMA resin material is comparable to CAD/CAM milled PMMA or the conventionally fabricated PMMA resin materials.
3D-printed resins provide adequate wear resistance for dental use.

  • Wear resistance of 3D-printed comparable to others.

  • Addition of filler increases wear resistance. So, materials with high filler content are recommended for fabricating long-term provisional restorations.
