About the American Board of Dental Sleep Medicine (ABDSM)

Dr. Alex Johnson has received board certification from the American Board of Dental Sleep Medicine (ABDSM) and has been awarded Diplomate status.

ABDSM certification signifies that Dr. Johnson has met established qualifications and demonstrated a thorough understanding of oral appliance therapy.

The American Board of Dental Sleep Medicine (ABDSM) is an independent board of examiners that was established in 2004 for duly licensed dentists who treat sleep-related breathing disorders.

The purpose of the ABDSM is to help set standards for the scope of dental sleep medicine, which includes oral appliances and upper airway surgery to treat sleep-related breathing disorders such as snoring and obstructive sleep apnea (OSA). It sets standards to assure professional dental and medical colleagues, patients, and the public of an acceptable level of education, training, and experience by those who become Diplomates of the ABDSM by examination.

The ABDSM recognizes those dentists duly licensed by law who have successfully completed the board-certification requirements established by the ABDSM. The American Academy of Sleep Medicine (AASM) recognizes Diplomate status granted by the ABDSM.

Dentists with a broad understanding of oral appliance therapy work closely with board-certified sleep physicians to treat sleep-disordered breathing. An oral appliance that is custom-made and fitted by a trained dentist, is an effective treatment option for patients who have been diagnosed by a physician with primary snoring or obstructive sleep apnea.
