In the Type II bone description, which region is identified as least favorable for implants?

• A. Posterior mandible
• B. Anterior maxilla
• C. Posterior maxilla
• D. Anterior mandible

Answer: (C)

In this Type II bone description, regional bone quality and available height determine implant suitability, with some areas clearly more favorable than others. The posterior maxilla stands out as the least favorable because it typically has poorer bone density and height due to sinus pneumatization and thinning of the buccal cortical plate. This combination reduces primary stability and increases the need for augmentation procedures, making it less ideal for implants than the other regions. The anterior mandible generally offers dense, reliable bone, and the posterior mandible usually provides good bone density, whereas the anterior maxilla often has thinner cortical bone but is still usually more favorable than the posterior maxilla in this context.
