Elastic Mandibular Advancement Appliance (EMA)

The EMA® – Custom appliance is a simple, patient-friendly oral appliance created for noninvasive treatment of snoring and OSA. The primary treatment mechanism of opening the bite and gently moving the mandible forward is achieved with the use of interchangeable elastic straps that offer varying degrees of mandibular advancement. The flexibility of these elastic straps provides unsurpassed lateral movement and overall TMJ comfort. The 2 mm thick pressure formed bases offer orthodontic retention (resulting in no tooth movement) and maximum anterior tongue space because there are no projections in the palate.The Elastic Mandibular Advancement (EMA®) appliance uses elastic force to advance the mandible. Hand plastic trays are pressure formed to the patient”s models and utilize the undercut areas of the teeth for retention. This insures that there will be no movement of the patient”s teeth. Bite planes are used to open the bite. Mandibular advancement is achieved with different length straps. The elastic pull can also be adjusted to suit the patient”s musculature. The straps provide complete lateral movement.The EMA® – Custom is available only to dental professionals

FullBreath Appliance

The design of the Full Breath Solution focuses on inhibition of tongue movement; inhibiting the rise and backward movement of the tongue so that it does not block the airway during sleep.

With a single arch appliance designed to provide subtle yet effective admustments, the Full Breath Solution imporves airflow 100% of the time and stops snoring with 95% of all patients.


Herbst Telescopic Appliance

The Herbst Appliance has been proven to be effective on chronic snoring and mild to moderate obstructive sleep apnea sufferers. This appliance allows patients to move laterally and vertically without disengaging the appliance. Also, if it is determined that the initial position does not provide the anticipated relief of the condition, the mandible can easily be moved forward by two options of adjustability. The first option is traditional hardware with sets of 1,2 and 3 mm shims for advancing those increments only. The second being the Telescopic version allowing the clinician to advance in ¼ mm increments by making one full turn of the protrusion collar up to 6-8mm from the start position. The appliance can be fabricated from hard acrylic, thermoactive and soft materials and is tooth retained via friction grip or clasps.The Herbst Appliance is a mandibular repositioner that has been in use many years for orthodontic and TMJ therapy prior to its modification for treatment of sleep disordered breathing.The greatest advantage of the Herbst appliance is that it allows for very quick, easy and accurate mandibular protrusive adjustability. This is accomplished through simple manipulation of the rod/sleeve plunger mechanism. Vertical opening varies is 5 mm and there is limited freedom of movement for the mandible in a lateral direction. Bilateral interarch elastics are recommended to keep the jaw closed during sleep.NOTE: Some clinicians feel that limited lateral movement of the lower jaw during appliance use is beneficial for TMJ comfort while others believe it is of no benefit. Also, some clinicians find compromised effectiveness if the mandible is allowed to drop down even as much as a millimeter during appliance use while others find no difference. These are both areas that require more scientific study. We are presently unaware of the precise effect of these parameters on appliance effectiveness.FDA Approval: Approved for treatment of snoring
Date of FDA Approval: March 1996

The LSWD is a mandibular advancement device. It is inserted in the mouth and fits on the palate like a retainer. It has a protrusive element (PE) which rests behind the lower anterior teeth to maintain them in a comfortable forward position. This allows the lower jaw to move freely from side to side as well as open slightly. The appliance will be dispensed with a suck down for lower anteriors which can be used as necessary. The protrusive element will extend downward approximately 10mm and thus prevent the lower teeth from disengaging it. Most unique is the feature that there is an anterior stop (no material on the posterior teeth) which serves to minimize clenching. Since clenching is a necessary component of bruxing, it will reduce bruxing as well. The patent is pending and it is FDA accepted for snoring.FDA 510 (k) for snoring. K062333

Nose Breathe Appliance

The Nose Breathe for Heavy Snorer [NB/HS] is a NEW tongue-retaining oral appliance. The tongue is held at the roof of the mouth and retained by a naturally occurring lip seal and tongue suction due to the negative pressure of the oral cavity. It is an anatomical feature of the human oral cavity, only found during nasal breathing. The breathing/swallowing/tongue placement mechanism must function synergistically for normal esophageal peristalsis activity, as well as for the normal cranio-facial development. If not, problems, such as, acid reflux, aspiration, COPD, crooked teeth, aerophagia, dysphagia, diabetes, asthma, bed wetting,. could result. The biggest culprit is the tongue activity during swallowing. Nasal breathing is the most effective way to control the aberrant tongue function. Nasal breathing/swallowing/tongue placement must be looked as a unit and not as separate functions.The Nose Breathe for Heavy Snorer is constructed of EVA (ethyl vinyl acetate) material, and is very comfortable. Upper and lower impressions are required and are custom-fitted. The bite is set in the normal occlusion. There is no pressure on the TMJ, and thereby, it will prevent permanent bite shift from occurring.The research study, “A New Tongue-Retaining Oral Appliance” by Rosalind Cartwright, et al. at Rush University Medical Center, Chicago was presented at the 18th Annual APSS Convention at Philadelphia in June 2004. The Abstract was published in the Journal of Sleep, Vol. 27, June 2004, 412. The result: nasal breathing can effectively control snoring and mild sleep apnea.The early control of snoring and mild sleep apnea is important because recent studies are showing that within six years heavy snoring could lead to high blood pressure, stroke, and OSA.FDA Approval: May 28, 2002

The OASYS Oral/Nasal Airway System is the first dental device to be reviewed by both the dental and ENT divisions of the FDA and to be approved as a dental device for treatment of snoring and sleep apnea through mandibular repositioning and also as a nasal dilator for reduction of nasal resistance and improved nasal breathing.The OASYS Oral/Nasal Airway System functions to:

  • Act as a mandibular repositioner
  • Act as a nasal dilator
  • Allow mouth breathing to occur, if required.

The OASYS Oral/Nasal Airway System is designed to achieve these functions with the following goals:

  • Maintain maximize the intraoral volume.
  • Minimize the force on the teeth.
  • Have no components that extend extra orally through the lips.
  • To reduce upper airway resistance.


The OASYS Oral/Nasal Airway System fits securely onto the lower arch only. The upper flange extends in front of the upper arch and under the upper lip. This maintains a slippage during mandibular movements during usage. There is a nature give to the wires that creates a yielding give when the mandible pulls back on the device. Provided is an upper splint that distributes the forces through the entire arch. Together these act to reduce the forces on the teeth.


The OASYS Oral/Nasal Airway System maintains maximal tongue space by positioning the connectors and adjustment components outside of the dental arch leaving the palate and anterior oral space completely free for the tongue to position itself up and forward. There is usually even an open space for the tip of the tongue to go between the incisor teeth.


Oral/Nasal Airway System maintains the patentcy of the oropharyngeal airway by functioning as a mandibular repositioner and as a nasal dilator by maintaining a stretch in the nasal labial tissue to dilate the internal nares.

Patients who are unable to be compliant with a nasal mask due to claustrophobia, head aches due to chinstraps or head gear and complaints of mask leaks leading to eye irritation, sinusitis may benefit by using oral mask ventilation with the OPA P. Oral positive air pressure delivered by a newly conceived proprietary dental appliance (OPA P) is a treatment alternative to nasally applied positive air pressure (CPAP or BiPAP). Mandibular advancement and modification of the upper airway structures is thought to enlarge the airway or reduce its collapsibility.The OPAP® is an oral appliance which incorporates an airway and mandibular position in its design and function. Lt assures an airway to the retropharynx during sleep and allows delivery of positive air pressure (CPAP or BiPAP) through it if needed. The combination of mandibular positioning and the creation of an airway allows for an alternative mode of treatment for the collapsible airway found in O SA patients. This type of dental appliance may be
used for mild to severe cases of OSA.Evaluation of the patient for the suitability of an oral appliance from a medical and dental standpoint is first determined. A referral to a dental sleep specialist is then made. A complete dental exam including panorex, cephalometrics in addition to sonography of the TMJ joint was obtained prior to taking dental impressions may be considered. A bite registration is then obtained, allowing the OPAP® appliance to be custom made to the patients dental impressions. Once a comfortable fit is obtained the OPAP® was connected to CPAP or BiPAP by the standard tubing. A titration polysomnogram test is then recommended with the O PAP and positive air pressure.Primary complaints with the OPAP® included oral drying, excessive salivation, discomfort with exhaling against CPAP. Drying improves with the use of an inline humidifier. Excessive salivation improved with adaptation and continued use of the oral appliance. Discomfort with exhalation against orally delivered CPAP improved with the use of orally delivered BiPAP. The OPAP® has been designed for patients with and without teeth­Data presented to the FDA demonstrated the OPAP® appliance delivered oral air pressure capable of producing a reduction of the AHl in mild to severe cases of OSA to the same level of efficacy as nasal mask delivery. This type of dental appliance may serve to be a therapeutic alterative to nasal CPAP and in certain mild cases this oral appliance is by itself capable of treating mild OSA.FDA Approval:

Somnoguard 2.0

One-part thermoplastic mandibular advancement device to treat snoring and mild to moderate obstructive sleep apnoea. Appliance consists of a hypoallergenic thermoplastic body. After heating the appliance in water that has been boiled the thermoplastic co-polymer becomes soft and mouldable. While soft, the appliance is fitted to the upper and lower jaws and once cooled it is ready to be worn at night. It differs from the preceding SomnoGuard by a 3.0 mm thicker molar biting zone. This thicker molar area means that fitting is faster and easier for those patients with a deep bite. The monobloc appliance exhibits the following features and advantages:

  • Easy fitting within minutes, preferably by physicians or their trained staff
  • Clinical efficacy well proven by several clinical trials performed with the SomnoGuard® with success rates between 50 to 80% in reducing snoring and RDI (i.e. Respiratory Disturbance Index). Literature references and detailed actual clinical trial outcome data is published on
  • Normally very well tolerated. Minor and temporary side effects refer mainly to hypersalivation and morning discomfort
  • Average life of about one year, and thus considered for short to medium term use
  • The most cost-effective option to treat snoring and sleep apnea


Somnoguard Adjustable

Dental lab made two-part mandibular adjustable positioner to treat snoring and mild to moderate sleep apnoea. The SomnoGuard AP Pro can easily be constructed from common acrylic/elastomeric thermoform dental materials in any detal lab after taking impressions of the lower and upper jaws and producing plaster models. The components used to connect the upper and lower trays of the dental appliance and enable the infinite advancement of the lower jaw are made from stainless steel. The components” technology is based on the preceding development of the SomnoGuard AP. The components are very durable, more or less inndestructable, inexpensive and can most often be reused when the oral appliance has to re-made for some reason. As well as the advantages of the SomnoGuard AP, the dental device SomnoGuard AP Pro provides the additional benefit that even patients with missing teeth or dentures can wear it. SomnoGuard AP Pro is considered for long term use between about three to five years or longer.

FDA Approval received for the complete line of SomnoGuard oral appliances (the 1-part boil & bite devices SomnoGuard and SomnoGuard 2.0, the 2-part adjustable boil & bite SomnoGuard AP and the two part custom made SomnoGuard AP Pro for fabrication by dental labs) the FDA 510(k) approval under the clearance number K061688 on September 8, 2006



The SUAD is also a custom-made appliance that is made of a heat-sensitive acrylic and is reinforced by a metal framework. The SUAD adjustment mechanism (Herbst) is positioned on the sides of the device and consists of a piston that slides within a tube. The appliance is comfortable on the teeth and the mechanism allows good freedom of movement of the jaw. Therefore it is used frequently in patients who tend to grind their teeth heavily. The position of the jaw can be adjusted by using small rings that slide over the piston and when the tube is positioned over the piston it will advance the jaw the width of the ring. Small elastics (rubber bands) are used to keep the jaw from falling open during the night although the patient is able to partially open the mouth, which can improve comfort when using the appliance.



The Thornton Adjustable Positioner (TAP) is a custom-made two piece adjustable appliance that is worn while sleeping. The trays of the appliance snap over the upper and lower teeth and hook together. The design is based on the same principle as cardiopulmonary resuscitation, CPR. The airway must be opened to allow air to pass through the throat. The TAP holds the lower jaw in a forward position so that it does not shift nor fall open during the night. This prevents the airway from collapsing. The more you pull your jaw forward, the more your airway will open.

The TAP is the only mandibular advancement device that can be adjusted easily by the patient or practitioner while in the mouth. This feature allows the patient to always be in control of their treatment. The unique design also allows the patient to fine-tune their treatment position at home to achieve maximum results.

Most patients experience relief the very first night they wear their TAP. Although it may take up to a week to get used to wearing a TAP appliance, this is a small hurdle for patients. Nine in ten patients wear the device all night, every night  making the TAP a highly effective solution for both snoring and sleep apnea.


  • Patient-friendly
  • Superior results
  • Easy to fit
  • Infinitely adjustable
  • Precise control of advancement
  • Interchangeable hooks
  • Freedom for lateral movement

Tongue Retaining Device (TRD)

The TRD is lab constructed of a flexible polyvinyl material adapted to the general contours of the teeth and dental arches. It does not depend on teeth for retention. Rather, the tongue is held forward by the negative pressure created in the vacuum bulb on the front of the appliance.The appliance is available in four tongue extensions and with or without air way tubes for patients with compromised airway patency. It is constructed in conjunction with the Kel Gauge (described in another section of this program.)Since the mandible is not rigidly or firmly held by the appliance, freedom of movement is possible during use. This would seem to make the TRD a good choice for the edentulous patient, the patient with periodontal disease and the patient with temporomandibular joint dysfunction.There is ample research available documenting the effectiveness for treatment of snoring and OSA in certain patients.NOTE: Mandibular repositioners have been successfully used in edentulous patients over dentures in certain cases where the dentures have had adequate retention. Mandibular repositioners have also been successfully used in patients with compromised periodontal status or TMJ function. In these cases, however, the clinician needs to be especially careful in design and follow up.FDA Approval: Approved for both snoring and OSA

    Undergoing Sleep study and definitely have sleep apnea with O2 dropping to 82 % at times. Apnea 11% of each hour. Have tried face mask over nose and mouth, but didn’t go well. Interested in options other than CPAP. Please give me names of dentists (Oral surgeons )in the central Florida area near The Villages, FL. who are qualified to work with MAD or other oral devices. Thank you.

    “Vivos Therapeutics” should be here… if compared with rest of the other treatment, you will find it more innovative and effective. Just in 12-24 months it will cure sleep apnea if it’s mild to moderate.

    Can you supply a list of Practitioners that are currently selling the Herbst Appliance. My current one is years old and would most likely need to be replaced. I live in Lancaster.
    Thank you

    I have unused CPAP medical supplies and don’t want to throw away (incorrect order items received that the company says not cost effective to issue return)…

    Need address so I can donate to your organization…

    My husband and I planned an European River Cruise for our 20th wedding anniversary. I asked my doctor about getting something to keep me from snoring. Since I have a normal BMI/weight, don’t drink or smoke or have any medical problems, he thought I should be tested for sleep apnea which can be accompanied with snoring. I completed a one night sleep study and learned that I did indeed have sleep apnea. The Sleep Doctor (MD specializing in this field) had me fitted for the SomnoDent. All this occurred in May, 2016 and our trip was the first few weeks of June. Man what a difference it made right away. The snoring stopped and I started getting the best rest due to treating the sleep apnea which was causing (unaware to me or my husband) me to wake up over five times an hour gasping for air. I wear the device every night and don’t even think about it being in my mouth as I drift off into a sound, uninterrupted sleep…………zzzzzzzzzzzzz

    I am using the TRD device that I get on EBAY for 5 dollars, and I do the throat and tongue exercises, plus the breathe aid nasal insert., by sleep rite

    I have both obstructive and central apnea. Just wondering how effective a device is with central apnea. My Dr. says the central apnea is more pronounced in my case than the obstructive.

      It probably will not be effective for central apnea as that is occurring from the brain not sending proper signals to the muscles that control breathing.

    My dentist did plastic-like, custom moldings with wide, rubbarized bands that can be interchanged. While the office refers to it as a ‘snoreguard,’ it sounds like the ‘EMA’ device. I got it as an alternative to the cpap for milder apnea. I am very disappointed in that the rubberized bands tear easily as well as, it has not helped my apnea one bit. Worst is what I was charged – they originally quoted me at $5,000, billable to my insurance & said my out of pocket would be no more than $1700. They have since billed my insurance for $9,000, who paid just $1100… and are billing me an additional $5,000! And, again…zero apnea relief!!!

      Wow, what a rip-off! The custom fitted Glidewell silentnite anti snore mouth guard was less than $500 from my dentist. My main objection to it is the replacement crosslinks are $15 from my dentist, and there are only 4 links of a particular length included on the plastic molding that you get for that money, so I’m paying a little under $4 per link for a cheap looking plastic injection molded thing. So far, I have needed to replace one every few weeks of use. I suppose that it depends on the individual and how much strain they place on the links while sleeping. Still….better than thousands of dollars if it works about the same.

    I knew nothing about sleep apnea before reading this article. It was interesting to learn that these type of appliances can help you to control snoring. We are planning on going on a road trip soon so hopefully this article can help me to avoid being a burden during the trip.

    I use a TAP. Fitted by my dentist. My cost was around 500.00. The plastic breaks down and discoloration occurs in about a year. Otherwise great relief! Can’t sleep without it! I still have a little snore that breaks through, but the apnea is gone.
