3M ESPE manual Opening Container, Removing Denture from Cast, Cleaning the Patient’s Denture

Opening Container

After the stone completely sets (5–7 minutes), carefully open the container, using a laboratory knife. Typically the denture will remain on the stone cast in the upper half of the container and an alginate impression of the external surface of the denture will be in the lower half of the container. Occasionally, the denture will come off the cast and be in the alginate — this is not a problem. Simply remove the denture from the alginate.

Rarely the alginate will come out of the lower container. If this occurs, simply separate the alginate from the stone and place the alginate back into the lower container. This usually occurs when the lower container is not filled adequately with alginate, or excess water is on the bottom of the lower container prior to filling it with alginate.

Removing Denture from Cast

Remove the denture carefully from the cast. Use a laboratory knife along the sides of the posterior edges and carefully tease the denture impression off the cast. Avoid prying with the knife on the heals of the maxillary and mandibular denture, as often these posterior areas are worn thin and may easily fracture.

Cleaning the Patient’s Denture

Before giving the denture back to the patient, be sure to remove residual Orange Solvent using standard cleaning practices; i.e., steam cleaning or ultrasonic cleaning.

With the Celara™ Denture Technique, the patient is never without their denture. The whole procedure, when mastered, should routinely take approximately 30–45 minutes, or 1–1 1/2 hours when fabricating the wax pattern in the dental office.
