Before dental cosmetic procedures, assist with preparing implants, veneers, dentures or braces. Detect and reveal bone loss associated with gum disease or alterations to bone structure due to infection. Reveal the position of tumours or cysts. Find the exact location of abscesses in the mouth. Look for tooth decay. Check whether there is enough space in a person’s mouth to fit erupting teeth. Monitor the development of wisdom teeth to see if they are impacted or not.
