Which statement about custom aligners is incorrect?

The statement that custom aligners can be used for all types of orthodontic treatments is not accurate. While custom aligners, such as those made by brands like Invisalign, are effective for many orthodontic issues—including mild to moderate crowding, spacing, and some bite issues—there are limitations. For more severe cases, such as significant overbites, underbites, or complex orthodontic conditions, traditional braces may be the preferred method due to their ability to provide more controlled tooth movement. Therefore, it's important to recognize that custom aligners are not universally applicable to every orthodontic situation.

In contrast, custom aligners are indeed removable, allowing for easy eating and cleaning, and they are created from precise 3D digital scans of the patient's teeth. Additionally, regular check-ups are necessary to monitor progress and make any adjustments to the treatment plan, ensuring the best outcome for the patient.
