Milled versus Pressure-Molded Occlusal Device Wear Characteristics against Zirconia
Occlusal devices are often provided to prevent wear of dentition and damage to restorative materials. In a dental landscape of increasing material choices and fabrication methods, there is a wide array of options from which to choose. If clinicians are less prescriptive and leave these decisions to the dental laboratory, then ease of workflow may influence which device is fabricated. Two commonly fabricated occlusal devices at a local dental laboratory include milled polymethylmethacrylate (PMMA) anda pressure-molded thermoplastic polyurethane (TPU)/polyethylenterephthalat-glycol copolyester (PET-G).
