WHAT IS OCCLUSAL SPLINT THERAPY?

Occlusal splint therapy may be defined as “the art and science of establishing neuromuscular harmony in the masticatory system by creating a mechanical disadvantage for parafunctional forces with removable appliances. A properly constructed splint facilitates a mutually protected occlusion.

WHAT TYPES OF SPLINTS ARE AVAILABLE?

The types of splints currently employed in occlusal splint therapy include permissive, nonpermissive, hydrostatic, and soft rubber (silicone) splints.

The permissive splints allow the teeth to glide unimpeded over the biting or contact surface. These include bite planes (anterior deprogrammer, Lucia jig, anterior jig) and stabilization splints (Tanner, centric relation, flat plane, and superior repositioning).

The nonpermissive splints have ramps or indentations that limit the movement of the mandible. Examples include an anterior repositioning appliance (ARA) and a mandibular orthotic repositioning appliance (MORA).

Soft rubber splints and hydrostatic splints function by separating the teeth. Soft rubber splints, however, do not provide the characteristics necessary for successful splint therapy. These splints can exacerbate bruxism, possibly due to premature posterior contacts related to the fact that these splints cannot be balanced.

HOW DO SPLINTS WORK?

Splints provide diagnostic information, allow muscles in spasm to relax, protect the teeth and jaws from the adverse effects of bruxism, and normalize periodontal ligament proprioception. These devices can also allow repositioning of the condyles and jaws into centric relation (CR).

MAXILLARY SPLINT

The unique form offers a variety of possibilities to individualize the splint.

  • Retention can be achieved with the central incisors, the lateral incisors, or all four
  • Force distribution to the canines if desired, for example with Class II Division 1 occlusion
  • Assures axial loading of mandibular teeth with minimal adjustment

If you do not need the palatal wings, simply remove them.

MANDIBULAR SPLINT

A dedicated deprogrammer for the lower arch.

  • Predictable avoidance of mandibular canine contact, even with extreme lateral movements.
  • Helps avoid invasive adjustment of irregular mandibular incisal edges.
  • Frequently simpler than a maxillary splint to fit and adjust.

The mandibular FOS also can serve as a classic maxillary deprogrammer. Simply turn it upside down and place it in the maxillary arch.

The indications for a simple midline point stop splint:<

  • Treatment of acute TMJ pain with limited opening/li>
  • Diagnostic placement to achieve a physiologic registration

laboratory service

  • Are teeth rotated or tipped and clinical relining unpredictable?
  • Is minimising your clinical chair time your first priority?
  • Do you prefer to have the support of an expert laboratory?

Our FOS service laboratory could be the answer

Our experts will analyse the models and help you design the appropriate splint.

The laboratory box is pre-addressed and the postal fees are paid. Simply make silcone impressions, complete the order form and post.

You will receive the finished splint within a week.

"Like many dentists, I started using deprogrammers diagnostically prior to restorative treatment.

More and more of my patients continued to use their splints for years. The disadvantages of existing products in both material selection and design became more and more apparent.

FOS splints are the result of this experience and three years of trials."


ABOUT FOS

The FOS (flexi orthotic system) comprises of a choice of either an upper or lower anterior splint made of medical grade polyester copolymer, designed to prevent headaches, migraines and associated head and neck pain caused by teeth clenching and grinding (bruxism). 

The objective of the FOS is to allow muscles in spasm to relax, protect the teeth and jaws from the adverse effects of bruxism, and allow normalisation of the periodontal ligament proprioception. These devices can also allow repositioning of the condyles and jaws into centric relation (CR).

WANT AN ALTERNATIVE TO NTI?

THE BENEFITS OF FOS

LABIAL FLANGE

Unlike the NTI, the FOS splint has a recession for the central incisors. Less internal adjustment is generally required to achieve a stable position (no rocking) prior to relining.

DISCLUSION ELEMENT

The NTI frequently loads the lower incisors with a labial force vector, leading to mobility or sensitivity. With 15 degrees additional slope to the palatal, the FOS generally requires less adjustment to achieve axial loading of the antagonists.

PALATIAL EXTENSIONS OVER THE CANINES

Palatial extensions are not required for 80% of patients, and with the FOS, these can simply be cut off.

MATERIAL

The NTI is manufactured with polycarbonate. The primary difficulty with polycarbonate is related to standard resins used in dentistry - monomers significantly weaken the polycarbonate. The application of MMA, EMA, or other low viscosity monomer to polycarbonate to improved bonding lowers the fracture resistance massively. It is also impossible to create a stable bond with methacrylates. 

Without a stable bond, a polycarbonate splint pre-form requires mechanical retention for the relining material or any external form corrections, and the interface will still demonstrate discolouration and infiltration of saliva / bacteria.

The FOS is manufactured with a medical grade polyester copolymer. While demonstrating similar physical properties in terms of transparency or fracture resistance, the copolymer is not affected by methacrylates - or any other solvents or materials generally used in dentistry.
