Which instrument is a carving tool used to shape acrylic or wax during denture fabrication?

• A. Acrylic trimming bur
• B. Birds beak pliers
• C. Archwire
• D. LeCron carver

Answer: (D)

In denture fabrication, shaping the wax and later the acrylic patterns relies on carving tools that let you sculpt and refine with precision. The LeCron carver is the instrument designed for this purpose, with fine, pointed, or curved working edges that enable careful carving of occlusal anatomy, borders, and smooth contours on wax patterns or acrylic resin. Its design focuses on removing small amounts of material to achieve realistic anatomy and proper fit, which is why it’s the best choice for shaping acrylic or wax during fabrication.

Acrylic trimming bur is used for removing excess acrylic material after processing, not for detailed carving. Birds-beak pliers are for manipulating or bending components, not for carving wax or acrylic. Archwires belong to orthodontics, not denture fabrication.
