Eruption Guidance Appliances
Eruption Guidance Appliances are molded polyurethane devices intended to guide teeth into the right positions as they erupt, typically in patients 8 to 12 years old. They can be effective in the short term for patients to whom they are recommended by orthodontists, when worn correctly. However, as the Australian Society of Orthodontists (ASO) warns, it is not yet clear whether these are effective in the long-term and that such appliances will not necessarily eliminate the need for braces later. The ASO says that Eruption Guidance Appliances cannot treat all orthodontic problems and that braces are still more effective.
