Type II bone is located in which jaw region?

Type II bone is located in which jaw region?

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

Answer: (C)

In implant planning, bone quality is described by density patterns that combine how thick the cortical bone is with how much cancellous bone lies beneath. Type II bone means a thick cortical shell surrounding a cancellous core. The posterior maxilla commonly shows this cortical-cancellous arrangement, so it fits Type II best. This region tends to have more cortical support at the crest with a substantial cancellous interior, compared with other areas where the pattern is more densely cortical or more cancellous.
