Sleep Herbst Appliance is Better than you Think

A Dentist was recently audited by his state board compliance committee for treating a patient with a Herbst sleep apnea appliance.  It was reported that this particular patient was not given a diagnostic sleep test prior to receiving treatment. A vindictive ex-staff member of this particular practice, who was the former Sleep Apnea Coordinator, turned the doctor into the state board.

In fact the Dentist assumed there had been a home sleep study done and began treatment via the Herbst appliance. In the chart notes, the Dr. had noted sleep bruxism and this particular patient was paying on a cash basis, not using his/her medical insurance.

As it turned out, This is yet another case of why the Herbst appliance is a Dr’s. best friend. The Herbst appliance has been in used in dentistry since 1909, it can be used to treat bruxism, TMJ, snoring and OSA.  If this particular patient had been given a monoblock appliance or OSA mouthpiece whose FDA intended use is exclusively sleep apnea the story would have turned out very differently. The Dr could have been found guilty by the State Board because a monoblock cannot be used to treat nocturnal bruxism and there is no other dental application for the appliance.

 

 

The Sleep Herbst Appliance is a mandibular re-positioning device that has been in use since 1909 in orthodontic and TMJ therapy, prior to its modification for treatment of sleep disordered breathing. I first learned about the Herbst appliance back in the 1980’s. Dr. Gene Williamson from  Atlanta was using it to treat TMJ at the time. Dr. Ed Spiegel began using and teaching the Herbst technique to treat obstructive sleep apnea (OSA) based on reports of successful snoring results for TMJ patients. The Herbst Sleep Appliance has been proven to be effective on chronic snoring and mild to moderate OSA sufferers.

The Sleep Herbst Appliance is extremely successful in the treatment of nocturnal bruxism due to the fact it allows patients to move laterally and vertically without disengaging the appliance. It has been shown that patients who suffer from nocturnal bruxism tend to move their jaw in a motion that resembles the figure eight. The lateral movement built into a Herbst allows the patient to move the jaw freely. This movement allows synovial fluid to flow freely through the joint, resulting in less jaw discomfort and/or occlusal changes for the patient. This benefit is not found in monoblock appliances.

Key to the function of the Sleep Herbst Appliance is the adjustable telescoping arms on the sides of the appliance. 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 the Telescopic version allowing the clinician to advance in 1/8 mm increments by making one full turn of the protrusion collar up to 4 mm from the start

position. At Gergens Orthodontic Laboratory, we start each appliance at +1 so you can retrude 1 mm. The appliance can be fabricated from hard acrylic, thermoactive and soft materials and is tooth retained via friction grip or clasps. 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, however it is usually 5 mm, there is limited freedom of movement for the mandible in a lateral direction. Bilateral inter-arch elastics are recommended to keep the mouth closed during sleep. A mouth closed posture will allow a lip seal allowing the patient to breathe through the nose or to use CPAP as a complimentary therapy.

There is no midline connection on the Sleep Herbst Appliance which helps extremely with claustrophobic patients. 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 research. We are presently unaware of the precise effect of these parameters on appliance effectiveness.  At Gergen’s Sleep Appliance Lab we make more of this appliance than all other appliances combined.
