Which instrument is used to contour and carve wax patterns on dentures?

• A. Wax knife
• B. LeCron carver
• C. Acrylic trimming bur
• D. Beebee crown shears

Answer: (B)

In denture fabrication, shaping the wax pattern with precision is essential, and you need a tool designed for carving wax rather than general smoothing. The LeCron carver fits that role with its slender, pointed blade and curved tip, which let you contour borders, refine the flange, and sculpt occlusal surfaces on the wax denture with fine control. This enables accurate shaping of the wax pattern to achieve proper fit, depth of sulcus, and harmony with the teeth arrangement before investing and processing. Other tools serve different tasks—wax knives are mainly for smoothing or spreading wax, while acrylic trimming burs and crown shears are used for trimming resin or crowns, not for detailed wax carving.
