ABSTRACT:
BACKGROUND OF THE INVENTION
It has been estimated that ninety million American adults and children snore and that one in every ten adults snores. Snoring can have serious medical consequences for some people. Snoring is the first indication of a potentially life-threatening sleep disorder called Obstructive Sleep Apnea. If not diagnosed or if left untreated, Obstructive Sleep Apnea could result in severe medical consequences such as systemic high blood pressure, cardiovascular disease and even sudden death.
Snoring is caused by vibration of the tissues due to air turbulence as the airway narrows and may be a sign that a patient is suffering from apnea. But not all snorers suffer from apnea. Snoring can be categorized by its severity. There is the snorer who snores but experiences no physical problems. Then there is the snorer who suffers from apnea, or the snorer who suffers from upper airway resistance. In some of these people, though they may not actually experience apneic episodes, their snoring is so loud and their breathing so labored, that it still wakes them, and their partners, numerous times throughout the night.
Many spouses, partners and/or children suffer through the night from the annoying noise of the snorer. Snoring not only disturbs the sleeping pattern of the snorer himself, it is also disruptive to the family life by causing lack of sleep to all involved. This leaves all involved unrefreshed, tired and sleepy throughout the day. It can cause sleepiness while driving, reading, working or doing other tasks.
A broad variety of intra-oral and dental appliances and devices are now available to treat a patient for snoring. Some known oral devices for treating snoring and obstructive sleep apnea are worn inside of the mouth and work by repositioning of the jaw, moving the mandible, lifting the soft palate or moving the tongue forward. The various classes of treatment devices that now exist include mandibular advancers and tongue advancers. These appliances work by advancing the tongue and soft palate away from the back wall of the throat. Other methods used to treat snoring include controlled positive air flow pressure systems also known as CPAP which require a nose mask and which are quite uncomfortable.
Other treatments for snoring include various surgeries, which are drastic steps to take to attempt to cure the problem however snoring can be so disruptive to a person's life and relationships, that some sufferers resort to surgery.
Another device which has been known is described in U.S. Pat. No. 6,467,484 to De Voss. The device of De Voss fits entirely over the teeth and presses against the inside of the mouth and the gums, making it uncomfortable for the user to wear. In addition, the device is held in the user's mouth only by pressure against the teeth from the groove in the U-shaped member that fits over the teeth. If that pressure releases for any reason, such as material fatigue, the entire device can fall off of the teeth, which could be a very dangerous situation.
BRIEF DESCRIPTION OF THE INVENTION
The sleep appliance of this invention is a dental oral appliance for use with patients who suffer with sleep disorders. Primarily it is designed to reduce or eliminate snoring and to open the airway for a sleeping individual who suffers with obstructive sleep apnea.
The appliance is physically designed similar to an upper (maxillary) orthodontic retainer, commonly called a Hawley retainer. It covers the inside (lingual) of the upper teeth and has an open palate (nothing covering the middle area of the palate.) Retention (holding ability) for the appliance is provided by clasps, commonly called Adams clasps, placed over the upper right and left molars. In the anterior area from cuspid to cuspid, there is a retainer wire that is the standard wire used on orthodontic appliances to hold the anterior teeth in place or to move them backwards (inward towards the palate [lingually]).
In the anterior area over the upper central incisors is a raised strip that extends from the incisal tip (biting edge) of the central incisors toward the lingual. It extends back from the middle of the central incisors (where they meet or touch each other) to the middle of the palate. This raised anterior area is to disclude or separate the posterior teeth. The net effect is to reduce spasm on the temporalis muscle and aid in reducing migraine and chronic tension headache pain that comes from bruxing and clenching (squeezing teeth together with potentially up to thousands of pounds of pressure). Nocturnal bruxing and clenching are the cause of pain coming from the spasmed temporalis muscle.
There is a transverse strip that extends from the inside (lingual) of the upper right molars to the inside of the upper left molars. This transverse strip extends from the right to the left and covers the tongue, holding it down.
To understand the effectiveness of the appliance, the mechanism of snoring and obstructive sleep apnea must be understood. While we sleep, the tongue falls back and up towards the palate and it partially or completely obstructs or closes the path of the airway. This results in snoring, obstructive sleep apnea, or Upper Airway Resistance Syndrome. The medical treatment for these maladies range from medication to a C-PAP (Continuous Positive Airway Pressure) machine. The C-PAP is nearly 100% successful when utilized. Unfortunately, the non-compliance for C-PAP use ranges from 50% to 80% depending where one searches in the literature. The American Association of Sleep Medicine designated dental sleep appliances as the number one alternative to CPAP. The sleep appliance of this invention is designed to treat the problem of tongue blockage when sleeping. It works by utilizing several factors. First, it changes the vertical dimension (height of the opening or separation of the teeth). This results in an increased opening of the airway. Second, the strip that runs transverse along the back of the appliance effectively holds the tongue down and does not allow it to fall back and block the airway opening.
OBJECTS OF THE INVENTION
Accordingly, several objects and advantages of the invention are as follows:
It is an object of this invention to provide a simple device to prevent or reduce snoring as well as Obstructive Sleep Apnea.
It is another object of this invention to provide a device, easily applied and easily tolerated, which will substantially prevent snoring.
Further objects and advantages will become apparent from a consideration of the following description and drawings.
