A group of Case Western Reserve University School of Dental Medicine researchers wanted more definitive research on retainer wearing. As a result, they recently conducted a study searching for more data.
The researchers randomly sent out 2,000 surveys to orthodontists in the United States and 658 responded.
It was discovered that 58.2 percent of orthodontists had prescribed removable retainers for their patients. Fixed lingual retainers that are constantly worn in one’s mouth were prescribed by 40 percent of orthodontists.
Most orthodontists prescribed removable retainers to be worn full-time for the first nine months after a patient had his or her braces removed. Orthodontists also want patients to wear these retainers part-time for the rest of their life.
