Final answer:
Contouring pliers are utilized to adjust the stainless steel crown to fit around the tooth after the height has been modified, not dental amalgams which are used for cavity fillings.
Step-by-step explanation:
After the height of the stainless steel crown is adjusted, contouring pliers are used to contour the fit around the tooth. Contouring pliers are designed specifically to adjust the shape and contour of dental crowns to ensure a proper fit to the natural anatomy of the patient's tooth. Unlike dental amalgams, which are used for filling cavities due to their durability and ease of manipulation, contouring pliers are a hand instrument used in the fitting process of crowns, rather than in the filling of cavities. It is important to note that while amalgams are approximately 50% mercury by weight, and raise concerns about mercury toxicity, they are not the correct tool for adjusting the fit of a crown.
