The TAP® splint

The TAP® splint has been developed in the 1990s by the American dentist and engineer Dr Keith Thornton. Dr Thornton works in the third generation as a dentist in Dallas, Texas and, among other things, has earned a reputation as an expert in TMJ disorders.

During his military service as a dentist of the US Navy in the Philippines, he was often involved in emergency operations and first aid measures. Patients suffering from shortness of breath or choking seizures could be effectively helped in a first aid measure by quickly bringing forward the lower jaw, leading to an opening of the pharynx.

When Dr Thornton dealt with the treatment of snoring and sleep apnea in the early 90s for the first time, he remembered this effective measure to open the throat area. It was obvious to him that it must be possible to advance the lower jaw and thus to open the posterior respiratory tract by using an appropriate splint construction.

Thanks to his study in engineering, he succeeded quite quickly in developing a mechanical construction incorporated in two dental splints, allowing the lower jaw to be advanced in a forward position – reliably and controlled. The “TAP®”, short for “Thornton Adjustable Positioner”, was born.

Within a short time, scientific studies confirmed that the TAP® splint represented a targeted and effective kind of treatment of snoring and sleep apnea. Even a 96 % success rate by wearing the TAP® splint could be established in the scientific study published by Pancer et al. in 1999: Evaluation of Variable Mandibular Advancement Appliance for Treatment of Snoring and Sleep Apnea in: Chest 1999, 116(6): 1511-1518

Today, the TAP® splint is one of the most widely used anti-snoring devices in the US.


TAP® - the quick and easy solution.

Whether snoring threatens your relationship or your health: the TAP® splint is the easiest way to help you. Your orthodontist or dentist fabricates your individual splint – without recourse to surgery or lengthy treatment. The splint makes sure your lower jaw is held in a forward position – thus keeping free your respiratory tracts and considerably reducing your snoring problems or, after precision adjustment, in many cases even completely eliminating it.

Thus, intraoral treatment devices have long been a recognized alternative to therapy with respiratory masks (nCPAP). Numerous scientific studies demonstrate the effectiveness of specific lower protrusion splints like the TAP® splint. The guidelines of the American and German Society of Sleep Medicine (AASM / DGSM), too, recommend intraoral devices for the treatment of snoring and light to moderate forms of sleep apnea as an alternative or complementing kind of therapy (DGSM (2009): S3 guideline non-restorative sleep / insomnia, in: Somnology 13 : 4-160)


    Bimaxillary devices show a high success rate in the treatment of snoring and mild to moderate sleep apne
    You can easily insert and remove the splint on your own.
    All functional elements are made of biocompatible and nickel-free materials.
    The splint is individually fabricated for you, allowing great mobility and continuous adjustment.

Six splint versions
for various kinds of indications

Basically, TAP® splints are suitable for all patients with a good teeth condition and at least 8 remaining natural teeth in combination with sufficient mobility of the lower jaw. Thanks to continuous research and development, four different splint options, a device for combined therapy and a test device are currently available for different occlusions and patient needs.

TAP® Standard

This is the version originally developed by Dr. Thornton, enabling targeted and effective treatment of snoring and sleep apnea. Featuring a long activation range with a frontal external titration unit, it can be easily adjusted by the patient.

  • Splint made of biocompatible resin
  • Protrusion adjustment device made of stainless steel
  • Indicated for initial bite Class I, III as well as in case of simultaneous bruxism
  • Removable positioning screw, exchangeable against TAP® cover plate
  • External front assembly, adjustable while wearing the splint
  • Titration / adjustment range: 20 mm

TAP®-T Matrix

With this version, the dimensions of the splint components have been substantially reduced. The protrusion adjustment device is incorporated within the upper jaw splint, thus guaranteeing lip closure at any time while wearing the splint. The TAP®-T upper protrusion adjustment device is made of a nickel-free biocompatible titanium alloy – a proven and suitable implant material. The lower guiding device consists of a high-strength stainless steel alloy.

  • Splint made of biocompatible resin
  • Upper protrusion adjustment device made of biocompatible titanium
  • Lower guiding device made of nickel-free stainless steel alloy
  • Indicated for initial bite Class I and III
  • Well tolerated by patients with nickel allergy
  • Adjustable in the mouth while wearing the splint
  • Titration / adjustment range: 7 mm

TAP®-T Reverse

The TAP®-T Reverse device incorporates a reduced upper protrusion adjustment device made of titanium. It has been specifically designed for patients with deep bite. Lower protrusion is adjusted by activation key from a palatal direction, as this reduced adjustment device can be incorporated behind the upper incisors in the DURASOFT® splint.

  • Splint made of biocompatible resin
  • Upper protrusion adjustment device made of biocompatible titanium
  • Lower guiding device made of nickel-free stainless steel alloy
  • Indicated for initial bite Class I, III and deep bite
  • Well tolerated by patients with nickel allergy
  • Titration / adjustment range: 4 mm


Construction of the dreamTAP is characterized by a modified mounting position of components, i.e. the adjustment device placed in the lower jaw. This structure creates more space for the tongue, thus offering even more wearing comfort for the patient. Thanks to exchangeable hooks, an adjustment of up to 15 mm can be achieved. dreamTAP® components are made of a nickel-free CrCo alloy fabricated by metal injection molding and therefore extremely solid.

  • Splint made of biocompatible resin
  • Protrusion adjustment device made of nickel-free CrCo alloy
  • Indicated for initial bite Class I, II, III and deep bite
  • Well tolerated by patients with nickel allergy
  • Titration / adjustment range: up to 15 mm thanks to exchangeable hooks
  • 10 mm lateral excursion
  • Great mobility for the tongue
  • Adjustable in the mouth while wearing the splint
  • Can be used with combined therapy
Combined Therapy


This nasal pillow mask has been developed for patients with low CPAP acceptance and is put in the upper jaw using a ThermAcryl mouthpiece. With its comfortable, yet absolutely stable fit that avoids slipping, the mask is completely sealed and does not leave annoying marks on face and nose. For use in the combined therapy, the TAP® PAP can be complemented by a lower jaw splint, thus reducing the mask pressure by advancement of the lower jaw.

  • Metal-free nasal pillow mask
  • Great fit thanks to soft nose pads in 3 sizes
  • Can be used In combination with lower splint for the combined therapy
  • Adjustment range: 20 mm
  • ThermAcryl mouthpiece for individual adaptation
  • No head straps
Testing device


Methods using devices such as the TAP® splint destined for protrusion of the lower jaw are particularly indicated for patients with primary snoring and mild to moderate forms of sleep apnea – without recourse to invasive or surgical measures.

The diagnostic testing device myTAP helps to establish whether bimaxillary devices are generally eligible for a patient. It is inexpensive, infinitely adjustable and easy to use.

Construction and design are based on the TAP® splint; the mouthpiece is made of ThermAcryl – a lightweight plastic material that can be softened in hot water and then adjusted in the mouth. The adjustment mechanism is used to adjust the optimal protrusion of the lower jaw. This position can be continuously adapted and modified at any time.

Watch the application video below on myTAP® to get acquainted with the step by step adaptation of the testing device.

  • Individual adjustment in the dental office in just 15 minutes
  • Slender design
  • Metal-free, no allergenic potential
  • Full lateral excursion
  • Titration / adjustment range: 20 mm
