Occlusal Splints

TDSA Digitally Milled Splints

Digitally Milled Splints

TDSA Digitally Milled Splints have made life easy and help you cut your chair time down.

Traditional methods of splint manufacture are highly technique sensitive and often lead to poor splint fit, over contour and hence poor patient compliance. They also, more often than not, require extensive chair side time for adjustments to achieve passive fit and an appropriate occlusal scheme.

The main benefits of CAD/CAM milling technologies are the elimination of individual human errors inherent in the casting and other technical processes resulting in time saving and higher level of predictability at both the technical and clinical level. This allows the milled occlusal splint to be more durable, lighter, thinner and less bulky, hence improving patient’s comfort and compliance.

Clinically, maxillary and mandibular impressions are taken and poured. An open centric bite is taken with no tooth contact and utilizing a vertical dimension stop. Use a custom vertical dimension jig to control the vertical relationship.

These models are digitized using a 3D scanner and virtually articulated in centric relation and the computer software also then calculates the centre of rotation of the condyle based on average values. The maxillary model is digitally surveyed and the outline of the occlusal splint is constructed. Splint dimensions are automatically analysed to ensure a minimum occlusal thickness.

This minimizes the risks of perforations of the splints (especially in the distal molar areas) or over-bulking of the splint which has significant dimensional issues anteriorly. Once the design of the splint has been digitally finessed, it is milled from a block.

Type of Splints

We offer a range of digitally milled splints according to suitability and preference for yourself and your patients. We also accept your designs and can discuss customisations where possible.

Flat Plane Splint

Flat plane splints allow full coverage with a flat occlusal table, allowing every tooth to contact in the opposing arch. These are enhanced by digital milling to allow your preference of indentation and coverage. These can be constructed for both the upper or lower arch.

Michigan Splint

The Michigan Splint is an adaptation of the flat lane splint. It allows full contact of the opposing arch but has added anterior or canine guidance as per your preference.

Farrar Splint

The Farrar splint has a unique dramatic inclined anterior plane to guide the mandible into a protrusive position as per your prescribed position. It allows contact only with the anterior teeth.

Deprogrammer Splint

This splint is similar to the Farrar splint, however, does not have a dramatic ramp, rather a smaller anterior element allowing only anterior teeth to contact.

DAASA Splint
Dual Arch Anterior Scribe Appliance

The Michigan Splint is an adaptation of the flat lane splint. It allows full contact of the opposing arch but has added anterior or canine guidance as per your preference.

NTI Splint
Nociceptive Trigeminal Inhibition

The NTI splint is an anterior bite stop appliance. This can be constructed for just the anterior teeth or extended to the 4-4. It allows only anterior contact, designed to help with TMDs, headaches and rection of masticatory muscle activity.

Gelb Splint

This splint was the initial design associated with treatment for the TMJ. It is a mandibular splint with posterior occlusal coverage to add to the vertical dimension. This splint helps recapture the disc by adjusting the position of the mandible, usually into a more protruded and inferior position in the fossa. The splint also has an anterior lingual stainless steel support bar to join to acrylic components and traditionally has two ball hooks mesial the to lower 6s.

All splints which have only an anterior point of contact prevent the mode of mastication from trying to fit the teeth together, leaving the TMJ to reseat into a position that allows the muscles of mastication to relax.

Care Instructions

  • Clean your appliance after every use with a toothbrush and lukewarm water. Brush gently.
  • After cleaning, rinse appliance under cool water. Air dry at room temperature.
  • Once completely dry, store in case.
  • DO NOT soak the appliance in mouthwash or alcohol.
  • DO NOT place in hot or boiling water or expose to excessive heat, as this will distort the appliance.
  • DO NOT bend or use unnecessary force on appliance

*No warranty or guarantee is provided

Dentist Information

Below are three important steps to consider when fitting the Endura Splint with your patient.

  • Try the Endura Splint in the mouth. If it is tight or not fitting passively, then
  • Place the Endura Splint in hot water for 10 seconds, shake off excess hot water and carefully place in the mouth. The Endura Splint bears unique thermoforming properties that allow for it to adapt to all dentition. It will not distort at body temperature.
  • Check occlusion and adjust where required.
