Definitions
- a number of oral appliances have been developed in association with various therapies related to the treatment of sleep apnea, snoring, bruxism, orthodontia, eating disorders and other medical and dental issues.
- Snoring is a condition affecting approximately forty percent (40%) of the adult population, while sleep apnea is believed to affect at least twenty (20) million people.
- bruxism consists of a static and/or dynamic contact between the dentition of the mandible and maxilla.
- Bruxism is commonly referred to as "tooth grinding,” which results in the physical destruction of tooth enamel directly leading to tooth decay as well as more serious problems.
- Bruxism affects nearly fifteen percent (15%) of the population and in advanced stages bruxism results in the abnormal and excessive grinding or clenching of teeth while an individual is asleep.
- Bruxism is medically classified as parasomnia or sleep disorder.
- temporomandibular joint syndrome (or dysfunction)
- TMJ temporomandibular joint syndrome
- the temporomandibular joint lies between the temporal bone of the skull and the mandible of the jaw, and allows the jaw to open and close.
- the joint is formed by a condyle on the mandible, which hinges and glides in and out of the depression in the temporal bone.
- TMJ can be caused by bruxism, malocclusion, trauma, and arthritis. There is also an indication that a posterior or backward displacement of the condyle of the jaw significantly contributes to TMJ pain.
- TMJ has been associated with a wide variety of physical aliments, including migraine headaches. TMJ related headaches can become so severe as to cause nausea and blurred vision.
- Most people afflicted with TMJ suffer from a myofascial pain-dysfunction syndrome primarily as a muscle problem related to dental/skeletal relationships and tensional factors. The effects can range from mild to severe, including pain in the joint area that can extend to the shoulders, back, neck, and sinuses.
- U.S. Patent No. 6,769,910 discloses a non-surgical oral appliance for improving breathing, and abating or completely alleviating snoring sounds, TMJ and bruxism while sleeping.
- the user is professionally fitted for the appliance such that the appliance positions the mandible in an open, protrusive, predetermined position such that the oral airway permits the enhanced passage of air.
- Oral appliances have been developed and prescribed in association with conditions in addition to the above-described oral, respiratory, dental and developmental disorders.
- AOA American Obesity Association
- obesity is a disease that affects nearly one-third of the adult American population.
- the number of overweight and obese Americans has continued to increase since 1960 — a trend that is not slowing down.
- Research conducted by the AOA indicates that 64.5 percent of adult Americans (about 127 million) are currently categorized as being overweight or obese.
- obesity causes at least 300,000 excess deaths in the United States alone, and healthcare costs of American adults with obesity amount to approximately $100 billion.
- weight loss methods and devices for enabling people to attempt to manage their weight problems.
- the most prevalent methods include dieting, exercising, medications, body wrapping, surgical procedures, etc.
- Other weight management solutions involve mechanical devices and dental appliances.
- One such device is positioned in the mouth to stimulate salivation and swallowing, such as disclosed in U.S. Pat. Nos. 3,224,442 and 5,052,410.
- U.S. Patent No. 5,924,422 discloses a removable, retainer-like device that is molded to fit the contours and configuration of the user's mouth.
- the upper surface of the retainer-like device is configured to fit the roof of the user's mouth, while the lower surface is configured to replicate the roof, or palate, of the user's mouth.
- the retainer- like device is adapted to be easily and quickly put into use, without any special training, by positioning it in the mouth with the upper surface against the palate, and pushing the retainer between the corresponding teeth. When worn, the device effectively lowers the roof of the user's mouth to reduce the overall volume of the oral cavity.
- the device is intended to be easily inserted and removed by the user.
- the oral appliance if it is to be effective, should be used in accordance with a prescribed usage schedule to attain the desired therapeutic benefits. Accordingly, the dental and medical professions, medical and dental insurers, parents and others interested in a user's compliance with a prescribed usage schedule for a respective device, recognize the paramount importance of developing systems and methods for ensuring a user's compliant use of an oral appliance.
