Fränkel II
Special Notes
To view prices, please create an account. The photograph shows our standard design. We can customize many of our appliances for your patient's specific needs - please see our auxiliaries and color chart (not applicable for nylon appliances).
Fränkel II also accomplishes transverse and vertical development of both the maxillary and mandibular arches. Construction of the Fränkel II allows for subsequent additional advancement of the mandibular portion of the appliance, largely eliminating the necessity for replacement appliances as mandibular growth occurs.
- Consultation with our laboratory is recommended to determine the optimum method of additional advancement techniques.

Appliance Specific
Technical Requirements • Upper and lower models are required. • Stone models are preferred. • Treatment-specific bite record is required. • Complete and signed Rx. Default Materials • Cold Cure Acrylic • Duraloy Practical Considerations • Models should reflect the resting depth of the vestibule (usually 10+ mm inferior to the gingival margins of #23, #26 and 10+ mm superior to the gingival margins of #3 and #14). • Construction bite should reflect the exact desired mandibular position with the following parameters in mind: CL - I: (FR-I, FR-IV) o Anterior-Posterior Correction: none. Lab FM - 91 Rev: 4/21/15 Page 6 of 6 o Vertical Opening: at least 2mm posterior inter-occlusal clearance. If opening is insufficient, the lab may be able to increase it on customers request in lieu of taking a new bite record. o Dental Midlines Relationship: skeletal symmetry is the objective regardless of mid-line alignment. Should there be a misalignment of upper and lower dental midlines in a desired construction bite, please diagram this on the Rx. CL - II: (FR-II) o Anterior-Posterior Correction: as desired, (usually 2-6mm of mandibular advancement) o Vertical Opening: at least 2mm posterior inter-occlusal clearance. If opening is insufficient, the lab may be able to increase it on customers request in lieu of taking a new bite record. o Dental Midlines Relationship: skeletal symmetry is the objective regardless of mid-line alignment. Should there be a misalignment of upper and lower dental midlines in a desired construction bite, please diagram this on the Rx. CL - II: (FR-V) o Anterior-Posterior Correction: as desired, (usually 2-6mm of mandibular advancement) o Vertical Opening: at least 2mm posterior inter-occlusal clearance. If opening is insufficient, asking the lab to increase it is almost certain to result in a non-fitting appliance. o Dental Midlines Relationship: skeletal symmetry is the objective regardless of mid-line alignment. Should there be a misalignment of upper and lower dental midlines in a desired construction bite, please diagram this on the Rx. CL - III: (FR-III) o Anterior-Posterior Correction: mandible is comfortably retruded. o Vertical Opening: at least 1mm clearance at the nearest posterior contact and at least 1mm inter-incisally. If opening is insufficient, asking the lab to increase it is almost certain to result in a non-fitting appliance. o Dental Midlines Relationship: skeletal symmetry is the objective regardless of mid-line alignment. Should there be a misalignment of upper and lower dental midlines in a desired construction bite, please diagram this on the Rx.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.

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
$32.00 Initial Registration / 25% Replacement Cost*
* Elastodontics and Twin Blocks: $39.50 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
