Polishing Protocol
What do you understand by the words abrasive and polishing agents? How and what are the agents used in polishing in gold restorations?
Answer:
Agents used in Polishing Gold Restorations: Gold is relatively a soft material. Therefore, it requires a different approach than that used for other metals used in dentistry. Slow-speed handpiece should be used in finishing and polishing gold alloy.
The technique consists of the following steps:
- Contour with carbide burs, heatless stone, or green stone (silicate carbide).
- Finishing with pink stone (aluminum oxide) or medium grade abrasive impregnated rubber wheels and points (brown and green).
- The final finish is done by applying fine abrasive-impregnated rubber wheels, cups, and points.
- Polishing is done by applying tripoli or rouge with rag or leather wheels.
