TOOLS

First review with the patient the agreed upon treatment plan and show patient sample of finished crown

Have patient read and sign informed consent for crowns

Select crown shade using mirror held by patient.

Apply topical anesthesia wait one or two full minutes

If using quadrant trays take an opposing arch impression as well as a bite registration.

Inject local anesthesia wait until it takes effect. Take two heavy body polyvinyl siloxane impressions using two triple trays or two quadrant trays.

Prepare the mesial and distal using the large tapered diamond or the 56 fissure bur as space permits

Reduce medial and distal with large tapered diamond. Reduce tooth enough so that medial and distal of prep no longer touch adjacent teeth

Reduce medial and distal with large tapered diamond. Reduce tooth enough so that medial and distal of prep no longer touch adjacent teeth

Use short needle nose red diamond to narrow mesial and distal to create space for 00 cord

Pack oo cord all around the base of the tooth, do not use aluminum sulfate (septin) use hemodent (aluminum chloride) instead.

Next use 2.00 mm bur to cut three occlusal depth cuts
