After arriving at Russellville Dental Lab, the impressions will be poured, trimmed, and mounted. If your case involves an impression in place, we will carefully pour the case and slowly expose the margin of the crown while maintaining the positive seat of the partial on the model.
The lab will be on the lookout for errors in the impression that might limit the clinical outcomes. Typical complications in this workflow are most likely to be improperly seated partials in the impression. We can usually see this immediately when pouring up, as the poor seat will lead to stone over the partial surfaces.
If all is well, we will scan and design the crown, and after milling and sintering the crown will be placed as either a “Copy Crown” mimicking the natural tooth, or it will be adjusted to fit under the partial if there was no preliminary impression.
If you were unable to capture a preliminary impression, and you request that the lab return the partial before the completion of the crown, we will be unable to guarantee fit without adjustment.
