Also known as a hard nightguard, this is a full-coverage splint with an even, flat occlusal surface providing contact for the opposing teeth.

  • Full occlusal coverage
  • No guidance - No ramp
  • Even, flat occlusal surface (following opposing plane of occlusion)
  • Point contact for each opposing tooth
  • Lower same as upper 

NOTE: Great Lakes can only fabricate digital splints/deprogrammers for models mounted with the following compatible articulators - SAM® 1, SAM® 2, SAM® 3 Denar® Hanau™. Modular Models mounted with other articulators can only be used for fabricating conventional splints/deprogrammers.

Appliance Specific

Occlusal Splint - Digital

Technical Requirement:

  • Stone models are preferred. Opposing model is required.
  • Treatment-specific bite record is recommended. If more than one bite record is provided please identify each bite record. Arbitrary Centric Occlusion will be used if no bite record is provided.

If providing mounted models:

  • Currently only SAM and Denar mounted cases (magnetic and screw-on) are accepted for digital fabrication. Mounting portion of the models should preferably be full thickness and not “hourglass” shaped.
  • Mounting stone must be used and not mounting plaster.

Default Materials

  • Clear Splint Biocryl and Clear Cold Cure Acrylic. Veriflex™, Durasoft with Cold Cure, Cold Cure only, or Clear Splint Biocryl only, may be used when requested or when technologically necessary.
  • Reinforcement metal or polyester mesh may be added upon request.
  • Stainless Steel clasps

Practical Considerations
•  Face bow mounted models are likely to result in fewer occlusal adjustments to the

  • All non-mounted models intended for digital splint fabrication, will be mounted for the benefit of digital scanning and milling.
  • These mountings will appear incorrect when attached to a conventional articulator.
    Consider mounting just the maxillary model. We will complete the mounting of the lower model to your bite record.
  • Consider not sending face bows or transfer jigs, as these do not travel well.
  • Consider the vertical dimension of the bite record.
  • Avoid perforation of the bite record. Splint will require more adjustments, if the lab is forced to alter the bite record. Ideal clearance at first tooth contact (usually in the posterior) is at least 1.5mm.
  • Index model bases well for durable articulation. Consider better, non-alginate impression materials.
  • Due to the extensive plastic to tooth contact, splints are very vulnerable to even minor model inaccuracy. Consider clasping for controlled retention. We will add clasps if deemed necessary. 
  • Protrusive bites can be sent to set the condylar inclination of the articulator if the case is fully mounted or upper mounted model only is sent by your office. Lab standard software articulator settings are 20° inclination and 5° Bennett.

General Requirements


  • Accurate impressions with any type of impression material are acceptable
  • Impressions must adequately reflect all relevant anatomy
  • Impression material must not be separating from the impression tray
  • Consider pouring your models right away if your impressions are moisture, temperature, or time sensitive
  • Impressions sensitive to moisture content should be wrapped in a damp paper towel and placed in a sealed plastic bag if models are not poured immediately
  • Only metal impression trays and those with VPS impression material will be returned
  • The nature of impression materials currently on the market may contribute to common model problems encountered in the laboratory. Have you encountered porosity (bubbles, voids) or poor surface quality? Plaster or stone mixes are water based and they interact with impression surfaces in a water-like manner. Liquids placed on solid surfaces will be either attracted to, or repelled from that surface in varying degrees. Please be aware when selecting impression material if it is hydrophilic or hydrophobic.

Hydrophilic: is attracted to, or can be wetted by water.
Hydrophobic: is when liquid is repelled or fails to bond with liquids.
Vinyl poly siloxane (VPS) options can be hydrophilic or hydrophobic. Alginate is hydrophilic.

  • There are advantages and disadvantages to these impression options but there are products on the market to help reduce the disadvantages. Surfactants and debubblizer sprays can be used to lower surface tension between surfaces making the impression material more hydrophilic and assure a better impression result.
  • Great Lakes carries ACU-flow™ a VPS impression material which is hydrophilic and requires NO surfactant spray for surface tension reduction, eliminating bubble formation. Surfactants must be used properly and excess surfactant should not be allowed to pool in the cusp tips. This can cause loose, sandy-like cusp tips. Excess surfactant needs to be blown out leaving a wet look only before pouring. 

Learn how to take a reliable impression


  • Plaster or stone models are acceptable. Generally, the durability of stone is preferred.
  • Models should be reasonably trimmed, yet sufficiently thick for strength considerations.
  • No horseshoe-shaped models; Models should have a base of at least 7mm in the thinnest area.
  • Bases will be added as necessary (for an additional fee) to models without bases or those lacking adequate base thickness or strength.
  • Please indicate if your model must be duplicated as work models may get damaged during the appliance fabrication process.

Bite Records:

  • Please package bite registrations carefully.
  • Bite records must not be left between models for shipment to the lab.
  • Dedicated packaging should be considered for brittle materials such as Delar wax.
  • Please identify the nature and the intent of each bite record, if more than one is being supplied.
  • Please consider mounting the maxillary model, before sending it to the lab, for those cases requiring mounting. Sending items such as facebows, bite forks, and mounting jigs through the mail often results in unreliable mountings.

Appliance Protection Program

Great Lakes understands that appliances may be lost or destroyed through the course of treatment. This obviously creates extra expense for your patient. That's why we created our Appliance Protection Program as a type of appliance insurance. This program may also be an asset in furthering the growth of your practice. Contact Laboratory Customer Service for more information.

As an additional service to our Laboratory customer, Great Lakes provides protection against loss or irreparable damage to any appliance fabricated by Great Lakes Laboratory. We believe we have a total service package unequaled anywhere in the lab industry when this program is combined with our existing benefits:

  • Competitive prices
  • Free repair or replacement of broken Biocryl II acrylic plates
  • Free acrylic repairs of any repairable functional appliance fabricated by Great Lakes
