Description
Occlusal splints, the guards worn over the teeth, are made from several acrylic materials, and their surfaces change with time in the mouth. The authors compare three clear resins: heat-cured, milled, and 3D-printed. They make 108 small specimens, polish one side of each, and measure roughness, hardness, and color change. Half of each test group then sits in dry storage for 30 days, and the other half ages in warm distilled water for the same period.
Roughness differs clearly between materials, with milled and printed samples starting smoothest, and polishing matters more than aging for that trait. Hardness also differs: milled resin is hardest, yet every material softens after aging. Color change varies too, and the milled resin shifts least. The authors rank the milled material best overall on the three surface traits they track.
