Making a remount cast

Making a remount cast

Prepare a “remount cast” BEFORE the patient’s next visit

The denture is placed in the remount jig that has been mounted on the articulator, a mounting ring is placed on the upper member of the articulator, and a plaster “remount cast” is poured directly into the denture. This plaster is built up high enough to engage the upper mounting ring. You will end up with a solid cast and “mounting” in one piece.

The following directions are a step-by-step guide to perform this procedure.

a)      After the dentures are polished and ready to be inserted, obtain them from the lab.

b)      Check the articulator to see that the condyles are locked in centric relation position and the incisal guide pin is set on zero.

c)      Place the remount jig and index on the lower member of the articulator.

d)     Block out all undercuts in the maxillary denture using wadded up wet paper toweling,  clay, wet pumice, Take One, or other suitable block out material (NOT WAX).  Place this in the maxillary denture’s ridge area.  Make sure the palate and at least 2 mm of the entire denture flange periphery are not covered.

e)      Place the maxillary mounting plate (which still has the mounting plaster attached from previous steps) on the upper member of the articulator.  This plaster will already have an index from the bottom of the original cast.

f)       Use sufficient mounting plaster to secure the denture to the upper member of the articulator (enough to replace the missing cast).

g)      Close the articulator and place a large rubber band over the upper and lower members to hold the pin fully closed on the incisal guide table.

h)      Make sure that all work is neat and accurate.
