Invisalign changes a pair of braces every two months, and it is best to take them off and disinfect them once a week. The wearer wears it all the time except eating, drinking, brushing and flossing, that is to say, patients need to wear it most of the 24 hours a day.

Wear the appliance for at least 22 hours every day, and then replace it with a new appliance every two weeks. The average patient's course of treatment will last from 12 to 18 months, depending on the patient's dental condition. For most patients, Invisalign's correction takes about 12 to 15 months, and a few patients will have a longer course of treatment, such as 18 months.

Characteristics of Invisalign:

1. Working principle: Compared with metal braces which use arch wires and brackets to correct teeth, Invisalign dental appliance corrects teeth through a series of transparent invisible brackets without brackets, and does not use metal arch wires of braces and brackets during correction.

2. Visual effect: it is invisible without metal braces, and Invisalign is almost invisible.

3, oral health: metal archwires and brackets in metal braces will stimulate the mouth, while hindering the cleaning of all teeth and gums when brushing. During the treatment, Invisalign can be used for normal brushing and flossing.

4. Wearing conditions: Do not remove the metal braces before the end of the treatment. Invisalign braces can be removed by themselves during the treatment.

5. Advantages of Invisalign braces: the correction effect is accurate, the teeth are arranged neatly according to the tailor-made plan, and they are completely made according to the computer-aided design of 3D molding of your tooth model.
