Carranza’s Clinical Periodontology Twelfth Edition-Chapter 74-6

Caption: Figure 74-6: Bone quality influences the load-bearing capacity.

Insight: There is more cancellous or spongey bone in the posterior maxilla (A) than in the anterior mandible (B) where the bone is more dense/cortical. In order to increase survival rates and stability shorter and wider implants with a larger surface area are used to compensate for this difference. Newer surfaces with “nano-architecture” also increase the surface area.
