Definitions

  • the present invention relates to a mandibular advancement device which is insertable in, and removeable from, the mouth by the user.
  • a mandibular advancement device for the treatment and prevention of snoring, sleep apnoea and similar disorders.
  • the present invention further relates to a mandibular advancement device for use by athletes participating in sport.
  • a mandibular advance device in the form of a mouthguard to improve airflow to optimise the athletes breathing during sports.
  • a muscular relaxation in the throat area can occur in humans during sleep. This reduction in muscle tone causes a narrowing of the individual's pharynx. In some individuals, this narrowing of the pharynx can cause snoring.
  • Snoring is a common problem and is caused by turbulence inside the airway during inspiration.
  • snoring is often a manifestation of sleep apnoea whereby due to the narrowing of the pharynx, respiration is temporarily suspended for a certain period of time. This suspension of respiration causes the individual to awaken from sleep and is often repeated which can affect the quality of sleep; thus, effecting a person's day to day life and performance.
  • a mouthguard (commonly also referred to as a gumshield or mouth protector) is a device worn in the mouth of the athlete which is intended to protect the teeth, gums and jaw of the user.
  • These conventional devices are adapted to fit over the teeth and a substantial portion of the gums of the upper jaw.
  • conventional devices tend to be bulky and the natural position which provides the most comfort to users tends to be the natural biting position of the jaw. This results in muscular relaxation of the throat area, causing a narrowing of the athlete's pharynx which can cause turbulent airflow inside the airway during inspiration. This turbulent airflow reduces the flow rate of air inside the airway, thus the breathing efficiency of the athlete is reduced.
