摘要: 口腔正畸托槽粘接后会导致牙面菌斑附着增加、菌斑内微生物平衡失调并引起釉质脱矿及牙周损害。常用的控制菌斑的方法效果很难保证,而托槽的表面抗菌改性可摆脱上述缺陷。目前,托槽表面抗菌改性常用的二氧化钛、银、聚四氟乙烯具有较高的抗菌、灭菌作用,可减少菌斑生物膜的形成。常用的涂层方法包括溶胶-凝胶法、液相沉积法、物理气相沉积法、电化学法和阳极氧化法等。抗菌涂层无口腔黏膜刺激性、无短期全身毒性及无遗传毒性,具有良好的生物相容性,可满足口腔生物材料的应用要求。

Abstract: The bonding of orthodontic brackets may increase dental plaque adhesion and promote microbial imbalance. This phenomenon subsequently leads to enamel demineralization and periodontal damage. Commonly used methods cannot control dental plaque, but antimicrobial modification on the surface of orthodontic brackets can eliminate this defect. Materials for antimicrobial modification include TiO2, Ag, and polytetrafluoroethylene, which can reduce plaque biofilmformation. Commonly used coating methods include physical vapor deposition, sol-gel, liquid phase deposition, electrochemical process, and anodic oxidation. Antibacterial coating exhibits favorable biocompatibility and prevents oral mucosal irritation, short-term systemic toxicity, and genetic toxicity. Thus, this method meets the application requirements of oral biological materials.

Key words: fixed orthodontic appliance, orthodontic brackets, antibacterial coating, fixed orthodontic appliance, orthodontic brackets, antibacterial coating
