This appliance allows patients some lateral and vertical movement without disengaging the appliance. Also, if the initial position does not provide anticipated relief, the mandible can easily be moved forward in small increments by using advancement shims, or with our telescopic hardware advanced up to 4mm with a 1mm retrusion.
This appliance can be made of hard acrylic, thermoactive resin (Variflex™), clear Biocryl, or soft EVA material.
Indications for use: Herbst® -
- Optimum tongue space
- Upper edentulous with at least 6 teeth on lower arch
- Full complement of teeth
- Midline deviations
- Minimal inter-incisal opening
- Maxillary tori
- Mandibular tori
Indications for use: Variflex Telescopic Herbst® -
Same as Herbst indications above, and the following:
- Extensive crown and bridge
- Short clinical crowns
- Longer tooth dentitions

- 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.

- 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.
- 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.
