Offering superior patient comfort, this full-coverage splint has one point contact for each opposing tooth. The anterior ramp provides lateral and protrusive guidance to disclude posterior teeth during function. Custom-formed to original models, its soft internal can be reformed chair side at initial delivery to compensate for slight model and bite inaccuracies in minutes. This appliance is also available as a Wearguard, or Flat Occlusal Plane.     


  • Anterior acrylc ramp - Standard angle 5° greater than required to disclude posterior teeth
  • Standard protrusive and lateral length extends from contact point to just beyond the labial surface of the upper anteriors (approximately 4-6 minutes)
  • CR bite and opposing models required
  • Full occlusal coverage
  • Lateral and protrusive anterior guidance  
  • Facebow transfer optimzes results          


Note: Models will not be returned unless requested. We are so confident with the precision fit of the Rhea appliances, that returning models is no longer necessary.

Appliance Specific

Occlusal Splint - Standard
Technical Requirements:

  • Stone models are preferred.
  • Opposing model is required.
  • Mounted models are preferred or upper mounted only and bite registration. 
  • 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.


Default Material

  • 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 mesh, polyester or metal may be added upon request.

•  Stainless Steel clasps and reinforcement bars.

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

•  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 contact (usually in the posterior) is at least 1.5mm. Index model base well for durable articulation.
  • Consider using 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. Lab standard articulator settings are 20° inclination and 5° Bennett.

General Requirements

Impressions:

  • 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.

Models:

  • 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.

We use the following articulators and their accessories in our laboratory:

  • SAM® 1, SAM® 2, SAM® 3

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.

Program Cost

$25.50 Initial Registration / 25% Replacement Cost*
* Elastodontics and Twin Blocks: $30.60 Initial Registration / 50% Replacement Cost

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

Program Terms

  • If the Appliance Protection Program is desired for an individual patient, it must be noted on the original prescription accompanying models and wax bite registration to the Laboratory.
  • An appliance protection fee per individual appliance will be applied to the original invoice.
  • Your document number will be noted on the original invoice. This, along with the fee charged is your record of purchase of the program.
  • If the appliance is damaged beyond repair, the damaged appliance, original construction models, set up, and original construction bite must be forwarded to Great Lakes with new models and wax bite registration if applicable. Please note on the new prescription that this remake was insured, and provide the document number noted on the original invoice.
  • If the appliance is lost, the original construction models, set up, and original construction bite must be forwarded to Great Lakes with the new models and wax bite registration if applicable.
  • Please note on the new prescription that this remake was insured and provide the document number noted on the original invoice.
  • Upon fabrication of a replacement appliance, a charge of 25% of the original appliance price will be applied, 50% for Elastodontics and Twin Blocks.
  • Because this program is designed to offer protection against loss or irreparable damage, design changes of any type will not be included in this program.
  • This program provides protection against loss or irreparable damage to an original appliance for a period of one year or one remake.
