Intended Use

The SomnoGuard® SP Soft is intended for the treatment of night-time snoring and mild to moderate obstructive sleep apnea (OSAS) in adults.

Device Story

SomnoGuard® SP Soft is a boil-and-bite mandibular advancement device (MAD) used to treat snoring and mild to moderate obstructive sleep apnea. The device consists of two independent trays (upper and lower) made of medical-grade polycarbonate shells with a thermoplastic copolymer lining. The trays are linked by a coupling protrusion mechanism using Polyoxymethylene (POM) connectors of varying lengths, allowing for up to 10 mm of protrusion and lateral jaw movement. A physician or trained staff member fits the device chair-side by heating it in hot water, molding it to the patient's teeth, and cooling it to set the impression. The device works by advancing the lower jaw to open the upper airway. It is intended for medium-term use (up to two years) and serves as a cost-effective alternative to custom-made dental appliances. It is used in clinical settings by dental or sleep specialists.

Clinical Evidence

No new clinical trials were conducted for this 510(k). Evidence relies on historical clinical data from studies in Germany, the U.S., and Belgium, alongside published literature (e.g., Pancer et al., 1998) and American Academy of Sleep Medicine guidelines. These sources confirm that oral appliance therapy is effective for managing snoring and reducing breathing arrests in mild to moderate OSAS patients. Imaging studies cited in literature demonstrate airway improvement with oral airway dilators.

¹ In some countries there is a second model of SomnoGuard® SP, named SomnoGuard® SP Hard. Both models differ in the thermoplastic impression material only. SomnoGuard® SP Hard uses PCL (Polycaprolactone) instead of Elvax, giving a higher retention. SomnoGuard® SP Hard is not intended to be sold in the U.S.

### Device Description

The entire family of SomnoGuard mandibular advancement devices is used for treating snoring and mild to moderate obstructive sleep apnea. The principal effect of all appliances is the advancement of the lower jaw, thereby opening the upper airway and reducing snoring and the breathing arrests due to mild to moderate obstructive sleep apnea.

SomnoGuard can be fitted without the need of taking a patient's dental impressions as a prerequisite to construct the ready-to-use device. SomnoGuard devices are "boil-&-bite" appliances. To prepare fitting of the appliance it is necessary to heat the appliance in hot water that has been boiled for approximately 3:30 seconds. Thereafter, when the device is removed from the hot water and has cooled down for about 10 seconds, a physician or his or her trained staff inserts the device into the mouth of the patient, thereby first the lower jaw into the lower arch, then the upper jaw into the upper channel of the device. The patient then puts forward his or her lower jaw commonly at normal bite conditions to approximately half the maximum extension possible, with the plastic still warm and mouldable, and then firmly bites the plastic. When doing this, patient sucks in while closing the mouth and pressing the tongue against the inner surface of the front teeth. In parallel, doctor presses his or her fingers on the outer walls of the mouthpiece to make sure that the appliance is properly moulded. The process is completed by fixing the bite impression by rinsing the device in cold water.

Boil-&-bite appliances are primarily considered by sleep specialists and dentists for shortterm use up to about one year or as a first-line screening device to determine whether patients suffering from snoring and / or mild to moderate obstructive sleep apnea (OSAS) respond positively to oral appliance therapy, the outcome of which cannot be predicted for any appliance available in the marketplace prior to its usage. Thus in case of no therapeutic effect larger investments for the much more expensive custom dental lab made appliances can be avoided.

SomnoGuard® AP (AP = Adjustable Positioner) as well as SomnoGuard® SP Soft (SP = Sagittal Positioner) are two-part infinitely adjustable appliances enabling a protrusion of up to 10 mm, allowing lateral lower jaw movement and breathing through the mouth whenever needed. The devices consist of two independent trays each with a thermoplastic body, and both parts linked to each other by a coupling protrusion mechanism. The outer tray shells consist of solid, clear and transparent medical grade polycarbonate. The inner lining which

{2}------------------------------------------------

accommodates the teeth impressions is made of a thermoplastic copolymer which is similar to that used with the previously FDA cleared SomnoGuard® one-part appliances. After the oral appliance is heated in a hot water bath its thermoplastic body moulds easily to the teeth and jaws allowing any medical doctor to very easily fit the device chair side.

The SomnoGuard® SP Soft two connectors, made out of Polyoxymethylene (POM), connect the lower and the upper part of the appliance. Each device comes with 6 connectors of different length, enabling individual protrusion of up to 10 mm.

With the SomnoGuard® AP an adjusting screw made of stainless steel allows the anterior adjustment of the lower tray against the upper tray between 0 and about 10 mm or even more depending on the length of the screw used. The adjustment is only possible extra-orally and when the upper and lower trays are disassembling both trays is also necessary for cleaning.

The highly cost-effective device is considered for medium term use up to two years.

All "boil-&-bite" appliances are simple to fit by dentists and other medical specialists, taking about 10 minutes and not requiring any special tools. Since compliance and treatment outcomes cannot be predicted with any oral appliance currently available in the marketplace as previously mentioned, it always makes sense from a cost and economical point of view to initiate treatment with a more economical boil & bite device before subjecting patients to a much larger investment for the fabrication of a custom made dental appliances such as the SomnoGuard AP Pro.

#### Intented Use Statement

The SomnoGuard® SP Soft is intended for the treatment of night-time snoring and mild to moderate obstructive sleep apnea (OSAS) in adults.

### Comparison of Predicate Devices

SomnoGuard® SP Soft and SomnoGuard® AP use identical materials for the thermoflexible impression material and the hard shell trays but have different connectors between the upper and lower jaw trays.

{3}------------------------------------------------

SomnoGuard® SP Soft and SilentNite® are made out of different materials and SilentNite® is individually made but they share the same connecting mechanism out of the same materials between the upper and the lower jaw trays.

All devices have an identical intended use, the reduction of night-time snoring and mild to moderate obstructive sleep apnea in adults.

Substantial equivalence is based on non-clinical data as it relates to the historical significance of oral devices that reposition the jaw and reduce or manage snoring. Pancer et al. described this in an article published in the journal CHEST in 1998, where they concluded that mandibular advancement devices (MAD) were 95% successful in reducing and/or controlling snoring. In addition the American Academy of Sleep Medicine (formerly the American Sleep Disorders Association) published in 1995 their Standards of Practice and Guidelines which demonstrated that oral appliances were effective in the management of snoring.

### Clinical Data

Own clinical data from clinical studies in Germany, the U.S. and Belgium, as well a numerous number of articles referring to other MADs repeatedly looked at oral appliances and their use for the treatment of snoring confirm that oral appliance therapy is an effective means by which snoring can be managed and breathing arrests due to mild to moderate obstructive sleep apnea can be reduced. This effectiveness is embraced from a variety of aspects including safety, convenience and cost.

In conclusion, a number of studies have shown improvement of the airway utilizing imaging associated with the use of oral appliances (also referred to as Oral Airway Dilators), which aids in the management and reduction of snoring as well as breathing arrests due to mild to moderate obstructive sleep apnea.

Clinical and nonclinical data indicate that SomnoGuard® SP Soft is safe and effective for its intended use and performs as well as the predicate devices.
