Effect of the incorporation of zinc oxide nanoparticles on the flexural strength of auto- polymerized acrylic resins.
Background: Auto-polymerized acrylic resins are commonly used in many applications in dentistry including in maxillofacial rehabilitation such as interim prostheses, denture repair, reline, orthodontic appliances, record base, among others. These substances, however, have some negative aspects such...
