Durable Urushiol-Based Nanofilm with Water Repellency for Clear Overlay Appliances in Dentistry

초록

With increased esthetic needs, orthodontics is an indispensable medical treatment in dentistry, and transparent clear overlay appliances (COAs) are in general use to fix teeth. However, COAs are easily worn out because of the lack of durability. Here, we applied a nanofilm onto COAs using urushiol (U), a durable coating material from plant via a layer-by-layer assembly technique. In particular, polymerized urushiol (PU) provided COAs with higher mechanical strength in the large-scale assessment, lower cytotoxicity, and intrinsic hydrophobicity for antimicrobial use. In this report, we inceptively attempted to functionalize COAs with nanofilm for advanced biomedical use.
