Which type of dental implant extends over the bone surface?

1. Endosteal

2. Sub Periosteal

3. Transitional

4. Root-form

The correct answer is: Sub Periosteal

The subperiosteal implant is designed to be placed beneath the periosteum, which is the layer of connective tissue that surrounds the bones. Unlike endosteal implants, which are inserted directly into the jawbone, subperiosteal implants sit on top of the bone but beneath the periosteum, making them particularly useful for patients who may not have sufficient bone height for traditional implants. This type of implant provides a stable base for prosthetic teeth in cases where bone grafting is not a viable option. Subperiosteal implants are typically custom-made to fit the shape of the jawbone, which allows them to provide adequate support for dental restorations while minimizing the need for extensive surgical procedures often associated with other implant types. Understanding the unique placement and design of subperiosteal implants is important for dental professionals when assessing patients' eligibility for different implant options.
