Type I bone is located in which jaw region?

Type I bone is located in which jaw region?

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

Answer: (B)

Type I bone is the densest bone type, made up mostly of cortical bone with very little cancellous bone. This dense structure provides very high primary stability for implants but offers limited vascularization, which can influence healing. In the jaw, this dense cortical pattern is most commonly found in the posterior mandible, where the cortices are thick and porosity is low. Clinically, this means you can expect strong initial stability when placing implants there, but you need careful drilling techniques and irrigation to avoid overheating. Regions like the anterior mandible or maxilla tend to have more cancellous content or thinner cortices, corresponding to lower density bone.
