A STEP BY STEP PROCEDURE FOR CLASS I, CLASS VI AND PIT GOLD FOIL

PREPARATION
Step 1. Anesthetic is administered and an extra heavy dam is placed.

Step 2. Removal of previous restoration is accomplished with a #55 or #56 straight fissure bur and caries can be removed with a small round bur and excavator.

Step 3. Place a cement base if preparation is deep.

Step 4. Cut preparation with a #55 or #56 straight fissure bur to a depth of 1.5mm. The walls are perpendicular to the floor and the shape is often oblong or teardrop.

Step 5. Smooth floor and place retention undercuts in corners or in the side of the walls with a #35 inverted cone bur.

Step 6. Remove irregularities at the cavosurface with a small Wedelstaedt chisel or a #7404 twelve fluted bur.

INSERTION
Step 7. Heat and anneal a pellet of Easy Gold of proper size and place in the preparation with a smooth small nibbed amalgam plugger. Condense and compact with a Ferrier #3 (.75 mm) straight condenser stepping systematically over the inserted pellet. Continue adding annealed pellets and condensing until two thirds of the preparation is filled.

Step 8. Anneal a 64th gold foil pellet and place along one portion of the wall overlapping the Easy Gold and the wall. Condense in a step by step starting in the center and working systematically out to the wall; always keeping gold between the wall and the condenser nib. Continue placing and condensing gold foil pellets against the walls which results in a saucer shape to the gold foil. Always keep the walls ahead or higher than the center.

Step 9. Continue adding pellets to the restoration until the desired contour has been achieved. Allow a slight excess for finishing.

Step 10. Confirm condensation with a Varney foot condenser (F 12).

FINISHING
Step 11. A vaselined 1/2 inch medium garnet disc, on a straight or contra-angle mandrel is used for bulk reduction of the gold to near contour. Be careful not to reduce tooth structure with the garnet disc. Remove tags of gold at the margins, created from the spinning of the discs at the margins, with a cleoid-discoid going carefully from gold to tooth. Air coolant is used continually on the tooth while discing and polishing is being done.

Step 12. A vaselined 1/2 inch fine sand disc is used in the same manner as above. Reduce the gold and tooth to the same plane and the final contour. Continue to remove gold tags from over the margins with a cleoid-discoid or the back of a gold knife.

Step 13. Use the beavertail burnisher to work harden the surface of the gold with the side and the flat portion near the tip in an up and down and sideways motion. Remove any remaining tags with the back of a gold knife or cleoid-discoid by drawing it parallel with the margins.

Step 14. A vaselined 1/2 inch fine cuttle disc is used in the same manner as described above to remove any ripples and scratches from burnishing the gold surface. Smooth the final contour and remove any remaining tags in the customary manner. If the ripples are deep, a vaselined sand disc should be used prior to the cuttle disc.

Step 15. Using a ribbed Young's soft rubber cup and dry flour-of-pumice, commence the polishing phase. Wash and dry. Use air to cool the tooth.

Step 16. Using a clean ribbed soft rubber cup and 15 micron aluminum oxide powder, repeat the above step.

Step 17. Using a clean ribbed soft rubber cup and 1 micron aluminum oxide powder, repeat the above step. The air, suction and rotating cup all stop at the same time. If the gold is well condensed and the finishing steps have been followed; a deep, dark rich luster will appear.
