Considerations
Dental reconstruction is performed on the study model with
material that withstands the heating temperature (plaster, resin,
mold, teeth, artificial teeth...). If using wax, a duplicate of the
plaster model must be made, as the wax melts with the heat of
the machine. The new (rehabilitated) model is laminated.
Note: Use only the indicated material (Milk or Soft plate), as
another type of material adheres to the resin. After laminating,
carefully remove the plate from the model and fill the plate space
where the temporary bridge will be built with self-curing resin,
then take it to the dental preparation. For use in the mouth, the
tray should be adapted to protect the limit of 1 or 2 teeth on each
side of the area and provide approximately 3 mm around the
gingival margin.
During preparation, the tray can be inserted into the mouth and
used as a reference for the preparation contour. It will provide an
anatomy similar to natural teeth and convenient occlusion with the
antagonist arch. The correct relationship is established in the
mouth and can be observed if all edges are well demarcated and
flawless. When the resin starts to heat up, the resin/tray assembly
can be detached and reseated so that it does not polymerize on
the preparations.
When the acrylic is fully polymerized, the tray must be removed by
bending or stripping it. The acrylic obtained will be practically
polished.
