What is considered type 4 bone?

Anterior mandible
Posterior mandible
Anterior maxilla
Posterior maxilla

The correct answer is: Posterior maxilla

Type 4 bone is characterized by a thin cortical plate and a soft, low-density bone with a large marrow space. This bone type is typically found in the posterior maxilla, making option D the correct answer. Options A, B, and C do not represent type 4 bone as described above. In contrast, the anterior mandible (option A) is often considered type 1 bone, while the posterior mandible (option B) is typically type 2 bone. The anterior maxilla (option C) is commonly associated with type 3 bone.
