  • Preparation process of dental and orthopedic acrylic materials with antimicrobial properties using copper nanoparticle technology
    Patent number: 11134687
    Abstract: The present invention concerns a new biomaterial used to manufacture antimicrobial dental devices, intended to control the growth of microorganisms in the oral cavity. These include removable dentures (RD) with copper nanoparticles technology and antimicrobial properties against dental pathogens, such as: Candida albicans, a pathogen responsible for denture stomatitis; Pathogenic Streptococcus mutans, responsible for the initiation and progression of caries formation; and Staphylococcus aureus, which causes periprosthetic infections. This removable dental material allows for the production of a new dental device to prevent and/or control oral infections caused by said pathogens, such as denture stomatitis, secondary caries, periodontal diseases, among others.
