Bone contouring and reshaping is known as?

• A. Osteoclasis
• B. Osteotomy
• C. Osteogenesis
• D. Osteoplasty

Answer: (D)

The main idea here is the terminology for surgically altering the shape of bone. Bone contouring and reshaping specifically refers to remodeling the bone surface to improve its contour and appearance, which is what osteoplasty describes. It involves reshaping or removing small amounts of bone to create a smoother, more functional ridge or profile, without intentionally fracturing or rejoining bone segments.

Osteoclasis would involve intentionally fracturing a bone to correct a deformity, which is more about altering alignment through a break. Osteotomy is a planned cut or separation of bone to change length, angle, or alignment, not just reshaping the surface. Osteogenesis is the process of bone formation and healing, not a surgical reshaping procedure.

So, osteoplasty is the correct term for bone contouring and reshaping.
