Question

Quizplus · Accepted Answer

Carborundum discs are commonly used for removing sprues in dental laboratory work. They are made of a composite material of abrasive particles bonded together with a resin, which allows for efficient and precise removal of excess material without damaging the surrounding structure. Carbide and diamond discs are also commonly used for cutting and shaping dental materials, but may be too abrasive or expensive for sprue removal. Stainless steel discs are not typically used for this purpose as they are not abrasive enough.
