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

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.

00 cord at. Bottom of sulcus

Green 2mm depth cuts

Use 1.5 mm for axial depth cuts. (Yellow)

Axial depth cuts. Being made
