Who needs an E-appliance? What problems does it solve?

  • Those who grind and clench their teeth – the E-appliance will eliminate or greatly reduce clenching or grinding. Even in those who still brux, the damage being done to the teeth will stop.
  • Those with headaches or facial pain – the E-appliance can significantly reduce or eliminate the pain by allowing the patient’s muscles to relax. It also allows the patient’s own anatomy and muscles to place the joint in the most natural position while reducing muscle activity.
  • Those who have had cosmetic or restorative dentistry – the E-appliance will protect any restorative or cosmetic dentistry and the natural dentition. The E-appliance creates longevity for restorations and prolongs the life of natural teeth.
  • Those who want to keep their teeth properly aligned – the E-appliance will hold both upper and lower teeth in their present position and prevent orthodontic relapse.
  • Those who are preparing for restorative work – the E-appliance helps create a stable joint position and muscle coordination, allowing you to balance a patient’s bite with confidence.
  • Those whose joints click or pop – the E-appliance reduces the forces in the joint by reducing muscle activity and stops the progressive breakdown of the joint.
  • Those whose symptoms make a diagnosis difficult – the E-appliance is an excellent diagnostic tool that allows you to distinguish between muscle problems and internal derangements of the joint. Using our protocol the E-appliance will identify those patients you should not treat.
  • Those who have cracks, fracture lines or weakened teeth – the E-appliance protects existing tooth structure and prevents further damage.
  • Those who don’t want or can’t afford to have their bite balanced or have restorative dentistry done – the E-appliance will help patients get in their “adaptive zone,” giving their teeth and joints time to rest and repair while they sleep. For most people, this – combined with blue dot therapy – will keep them in their adaptive zone so continued damage is minimized or eliminated.

Why is the E-appliance better than any single arch appliance?

  • Success with the E-appliance does not depend on the dentist’s ability to manipulate the joint. With a single arch appliance, the dentist must manipulate the joint into the correct position.
  • Success with the E-appliance does not depend on the dentist’s ability to balance the bite on the appliance. With a single arch appliance, the dentist must perfectly balance 14 separate contacts. The E-appliance has only one contact.
  • The E-appliance is self-adjusting, and places the joint in the most natural position. A single arch appliance must be monitored and readjusted to keep the joint in its most natural position.
  • With the E-appliance, no back teeth touch, so interferences cannot create wear. A single arch appliance allows the back teeth to touch, which can create interferences as it wears.
  • The E-appliance does not need to be adjusted as it wears, because it is self-adjusting, avoiding interferences that stimulate grinding. As a single arch appliance wears, interferences are introduced, so it needs to be constantly adjusted to stay balanced.
  • The E-appliance does not have to be tight to keep it from dislodging or moving, because all forces applied to it will keep the appliance in place. (The E-appliance cannot go into crossover.) Most appliances must snap into place to prevent the appliance from dislodging during function and crossover.
  • The E-appliance allows a patient’s own muscles and anatomy to place the condyle in its most natural position. You will not have to manipulate the joint yourself to find centric relation – it goes there naturally when the E-appliance is in place. With a single arch appliance, you must be skilled at manipulation to get the joint in its most natural position.
  • The E-appliance only requires five or ten minutes of chair time to deliver. A single arch appliance may have to be relined and adjusted, which can take an hour or more.
  • The E-appliance is an easy to use diagnostic tool. When a patient wears the E-appliance for a single night, the absence of pain in the morning indicates a muscular problem that can be predictably treated. Pain that persists or increases indicates an internal derangement, which requires a different treatment. A single arch appliance will allow you to make a proper diagnosis only if it is properly balanced and the joint is in its most natural position.
  • The E-appliance can truly monitor stability over time because it stabilizes the upper and the lower teeth. With a single arch appliance, only the upper teeth are stabilized. The lower teeth can move as the appliance wears.
  • Studies have shown that proprioceptive input from the teeth increases muscle activity and bite force. The E-appliance blinds proprioception of the upper and lower teeth so that bite forces are reduced. A single arch appliance allows proprioceptive input from one of the arches, which increases bite force.
  • Wearing the E-appliance allows the entire masticatory system to rebuild and rest at night, while protecting upper and lower teeth, preventing future wear, cracks and breakdown.
  • Regular wear will allow many patients to get within their adaptive zone and stop – or significantly reduce – breakdown.
  • The E-appliance acts as a retainer to keep teeth from shifting and prevents grinding during the night, thereby preventing orthodontic relapse.
  • Regular wear will increase longevity of existing teeth for patients who choose not to have their bite balanced or have dental work done.
  • This double-arch appliance is smaller, thinner and easier for patients to wear, which improves patient compliance.

What is the E-Appliance?

The Problem
The E-appliance is a patented double arch orthotic. Its unique design solves bite problems and their symptoms. It is easy to deliver, easy to use and – for the first time – allows us to stabilize the entire masticatory system.

Many people experience problems resulting from improper positioning of the tempromandibular joint, bite problems and associated musculature. The excessive bruxing and clenching this causes may lead to excessive wear, loose teeth, rotation or migration of teeth, cracked or broken teeth, headaches, pain or tenderness of the joint and associated musculature, popping or clicking of the joint, deterioration of the joint, or other problems. As dental technology advances and people demand more effective treatment options and more complex cosmetic procedures, reducing or eliminating such problems becomes increasingly important.

Other oral appliances cover a single arch to prevent teeth from grinding against one another during sleep. Although such oral appliances can reduce certain symptoms of grinding, they cannot maintain their effectiveness over a long period of time, due to their inability to stabilize the opposing teeth. Furthermore, natural physiological triggers (interferences in the appliance) can continue to cause deterioration of the joint despite use of such oral appliances.

Even if an appliance is constructed and adjusted so that the opposing teeth contact the appliance at the same time – a difficult and time-consuming process – the positions of the opposing teeth may continue to shift, which necessitates continued adjustment of the oral appliance. If the appliance is not continually adjusted, the appliance – with interferences – perpetuates additional instability and deterioration will occur. These and other deficiencies have made previous oral appliances inadequate for the needs of our patients.

The solution
The E-appliance can reduce or eliminate problems and disadvantages associated with previous oral appliances. The two arches contact one another using a single anterior bearing point on a flat plane, which allows the user’s muscles and anatomy to move the joint into its proper natural position.

Because the E-appliance ensures that the joint is in its proper natural position and eliminates proprioceptive input to the muscles, bite force is reduced, and masticatory system harmony is established.


Prescribing the E-appliance

Preparation for the E-appliance is a simple process. Impressions are the most important part of this process – nothing the lab can do will compensate for inaccurate impressions. if you need help making your impressions, please contact our office. We will be happy to help you.

  1. Take perfect, bubble-free impressions of the upper and lower arches using crown and bridge impression material.
  2. Take a maximum protrusive bite and a CO bite.
  3. Send the impressions to our office for us to pour. Please use impression trays that do not need to be sent back.
  4. Along with each case, send a completed prescription form.
    • Make sure to indicate which appliance you are ordering.
    • Indicate in the special instructions how tight or loose (the amount of snap) you want in the appliance. Remember – the appliance works better if it is not too tight.
    • The patient’s appointment date must be indicated on the form.
  5. Make sure to send:
    • A CO bite.
    • A maximum protrusive bite.
    • Upper and lower impressions or models.
  6. To compensate for curve of spee, indicate if we should provide more vertical opening or provide steeper guidance.
  7. You must pre-schedule all cases. You may contact Eubank Laboratories by fax, 972.867.2219; by phone (toll-free) 888.596.1811 ext. 309; or by e-mail, tabatha@therightfitdentist.com.
    Should a problem occur, please contact our office. We are here to help you! Please note:
    • Casts fracture routinely during fabrication, and impressions break loose from the tray.
    • When bites are not received, our technical staff will arbitrarily hand articulate the models together
    • Make sure that the impressions and/or models have been checked for distortion and/or voids.
