While small precision stainless steel braces are the “gold standard” in cosmetic dentistry, some patients may prefer Invisalign models to improve their teeth.
This is the opinion of US-based orthodontist Dr Dan Murphy, who told the Union of Grass Valley newspaper that certain people need specialist equipment.
“In very select cases even appliances such as Invisalign, a sequential series of clear aligning trays designed to move teeth [are available],” he said.
Last month, Dr Majed Moawad noted in an article for the Woodinville Weekly that Invisalign braces are typically worn for between 20 and 22 hours a day to ensure optimal realignment.
However, Dr Murphy admitted this is not as common as precision steel braces, which are generally all that is needed to ensure an individual’s teeth remain straight and well-placed.
Made out of hi-tech metal alloys, braces are able to exert micro-forces on teeth that gradually move them into their proper positions, he explained.
