Important to every case… |

| Prescriptions: | Please provide a complete and signed Rx with every case. Click here to access Rx forms and shipping labels. |

|
| 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 PVS impression material will be returned. |
|
|
|
| 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. |
