Dental splints are dental appliances made of transparent plastic, which are worn in the upper or lower jaw. If the splint is intended to counteract teeth grinding, it is also called a grinding splint.

There are many different types and shapes of splints with different degrees of hardness and manufacturing techniques.

Depending on the shape, hardness and manufacturing process, the splints differ in their function, effectiveness and biology.

Tasks and function of the dental splint

1. protection of teeth from the high forces of pressing and grinding.

Provided the splint is correctly fitted and there are no interfering contacts, all dental splints can perform this task. The plastic of the splints can absorb the force and destruction of the tooth structure is prevented.


2. relaxation of the chewing muscles

The classic splint for relaxing the masticatory muscles is the Michigan splint.

This splint is made of hard plastic and provides the temporomandibular joints with a range of motion, which leads to relaxation via reflex arches.

The freedom of movement is created by unkeyed, free contacts on the occlusal surfaces and a guided lateral movement of the mandible over the canines – so-called canine guidance.


3. correction of the temporomandibular joints – MAGO therapy

Many people, in addition to protecting their teeth and relaxing their muscles, also need correction of their temporomandibular joints. This point is the most complex and requires the practitioner to have a very specific knowledge and experience in the field of

The only splint which, in our opinion, is suitable for this purpose is the MAGO splint. This splint relieves the jaw joints, allowing them to regenerate. Regular adjustments of the splint accompany this regeneration and the temporomandibular joints can reach their ideal and harmonious position after 4 to 18 months. In this case, the splint must be worn around the clock. Accompanying therapies to improve ascending problems are very important at this time (e.g. osteopathy, physiotherapy).

The main cause of disturbed temporomandibular joint position is incorrect tooth position, which forcibly pushes the temporomandibular joints into a pathological position. The MAGO splint addresses this cause and decouples the influence of the teeth on the temporomandibular joints. Consequently, the temporomandibular joints move to where your actual healthy position is.

When wearing the splint, complete physical harmony should have been achieved and the CMD symptoms should have disappeared as far as possible.

After the MAGO therapy is completed, the temporomandibular joints are where they belong, but the teeth have remained in the old, problematic position. Consequently, the next step is to correct the teeth and adjust them to the new, balanced jaw position. This bite reconstruction is usually done by building up the teeth with ceramic partial crowns, crowns and/or veneers. For this purpose, the most tooth-friendly method is selected for each individual tooth on the basis of an elaborate analysis and planning. In rare cases, concomitant orthodontic treatment (braces) may be required.

For patients with severe CMD, MAGO therapy with subsequent correction of tooth position is, in our opinion, the only functioning, cause-specific form of therapy that provides a permanent solution.

Dental splint materials

Splints can be soft or hard, depending on the material used. We clearly recommend the hard dental trays and discourage the use of soft materials: These are interpreted by the tooth receptors as soft food, which, via reflex arches, stimulates constant muscle activity.

The following plastics can be used as material for dental splints:

  • Poly-Methyl-Meth-Acrylate (PMMA)
  • Polyethylene terephthalate (PET)
  • Polyethylene Terephthalate Glycol Copolyester (PET-G)
  • Urethane di-meth acrylate (UDMA)
  • Urethane Meth Acrylate (UMA)
  • Polyethylene (PE)
  • Polypropylene (PP)
  • Polystyrene (PS)
  • Ethylene vinyl acetate (EVA)
  • Thermoplastic polyurethane (TPU)
  • Thermoplastic Polycarbonate (TPC)
  • Polyvinyl chloride (PVC)
  • Meth-acrylic ester (MAE)

With this abundance of materials, it is very important to use exactly the material that ideally fulfills the function and puts as little strain on health as possible.

Making the dental splints

There are also different options for the production.

  • The material can be heated and thermoformed onto the tooth model. Additional material is applied to the resulting thermoformed rail, which gives the rail the necessary shape.
  • The rail is printed or printed with a 3D printer.
  • The splint is milled out of a plastic block using the CAD/CAM process. In the picture you can see such a blank, with the tooth splint milled out.

The manufacturing process should also always take into account the function, durability and biology.

FAQ on the subject of dental splints

How should rails be cleaned?

The dental trays should be cleaned daily with clear, mild detergent or clear liquid soap. A soft toothbrush can be used well for this purpose. Please do not use any aggressive agent and hard brushes.

How long should the MAGO splint be worn daily?

The MAGO splint must be worn at least 24 hours a day and only removed for brushing teeth or cleaning the splint.

Should the MAGO splint also be worn while eating?

Since the temporomandibular joints regenerate, but the teeth remain in the same position, it happens that after a few weeks/months the teeth no longer fit together. Consequently, the splint should be worn while eating: Otherwise, the temporomandibular joints will be pressed into the old, wrong position by the teeth at every meal. This makes undisturbed regeneration impossible.

What are the disadvantages of MAGO therapy?
  • The splint must be worn around the clock
  • The subsequent reconstruction of the teeth with ceramic partial crowns, crowns and veneers results in higher costs.
  • The total duration of therapy is usually 4 to 18 months. The time depends on the individual regeneration period of the temporomandibular joints and can vary greatly.
Is there any therapy that can treat TMJ and CMD problems as effectively as MAGO therapy?

No, we are not aware of any other solution that addresses the cause to the same extent and can treat CMD in such a causal way.

Can a dental splint also be worn over implants?

Yes, the MAGO splint can also be worn over implants.
