Evaluation of the Effect of Nanocoating on Mechanical and Biofilm Formation in Thermoplastic Polyurethane Aligner Sheets.

Objective: The objective of this research is to determine whether the thermoplastic polyurethane (TPU) coated with carboxymethylcellulose chitosan has better mechanical and antibacterial action (anti-) when utilized in intraoral simulations with synthetic saliva.

Materials And Methods: The TPU sheets ( = 45) were divided into three groups. Control ( = 15) consists of as-received TPU sheets.
