Which implant is used when the bone height/width is insufficient?

1. Plate form implant

2. Endosseous implant

3. Subperiosteal implant

4. Root form implant

The correct answer is: Subperiosteal implant

The subperiosteal implant is specifically designed for situations where there is insufficient bone height or width. This type of implant is situated above the jawbone and beneath the gum tissue, resting on the bone structure but not inserted into it. This makes it particularly suitable for patients with significant bone resorption, where traditional implants may not have enough bone support. In contrast, other types of implants, like the root form implant, are designed to be anchored directly into the jawbone, which requires adequate bone volume and density for stable integration. Plate form implants also require specific dimensions of bone to be properly placed. Endosseous implants, like root form implants, depend on the available bone for secure placement. Therefore, the subperiosteal implant is the best choice when the bone height or width is lacking, as it does not require the same structural support from the bone as other implant types.
