Clear braces generally refer to invisible braces, which are effective. Invisible aligners are made using elastic polymers through a computerized 3-D diagnostic, design and manufacturing system. Invisible aligners will apply a certain strength to the teeth, and have good corrective effect for misalignment of upper and lower teeth, crowding of teeth, and thinning of teeth, which can be restored to the normal state of the teeth through the treatment and make the teeth more beautiful. Invisible aligners are not effective in treating more complicated malocclusions such as severe crowding and anterior protrusion of teeth, and cannot effectively straighten teeth. When using invisible aligners, if the patient does not wear them on time and change them regularly, the straightening effect will also be unsatisfactory or the straightening time will be prolonged. If you need to have your teeth straightened, it is recommended that you visit a hospital for treatment under the guidance of a doctor.
