A treatment process involves multiple aligners. Each Leetray aligner is designed based on a scanned jaw model, so it is absolutely accurate, close to the dental arch from the first stage.
Not operating under a "pull" mechanism like traditional braces, clear aligner operates on a "push" mechanism based on the fit of the tray to the teeth and attachment buttons are attached on the teeth to activate the teeth movement more easily, faster, according to the treatment plan. Each tray will help the teeth move a certain amount, so it is very convenient for the doctor to monitor during the orthodontic process, as well as can reduce the treatment time compared to traditional braces in most cases.
