Which surgical procedure recontours bone structures in preparation for a prosthesis?

• A. Osteoplasty
• B. Gingivoplasty
• C. Alveoplasty
• D. Osteoectomy

Answer: (C)

The main idea here is reshaping the jawbone that supports a denture to create a smooth, even foundation. Alveoplasty specifically recontours the alveolar ridge bone—removing irregularities, spicules, and sharp edges and shaping the ridge to a uniform width and contour. This improves denture fit, stability, and comfort by giving the prosthesis a dependable base to seat on. The other options don’t fit this context as well. Gingivoplasty reshapes the soft gum tissue, not the bone. Osteoplasty is bone reshaping in general but not limited to the alveolar ridge for prostheses, and osteoectomy involves removing bone rather than smoothing and contouring it for denture support.
