Which bone density type is the densest (most cortical bone, least trabecular)?
Show answer and explanation
Correct answer: A. Type I
✓ A) Type I is the densest bone.
Misch bone density classification: Type I = dense cortical bone (anterior mandible symphysis) — most dense, but poor vascularity, highest drilling resistance, risk of overheating; Type II = thick cortical + coarse trabecular (posterior mandible); Type III = thin cortical + fine trabecular; Type IV = thin cortical + fine trabecular (posterior maxilla) — least dense, worst implant prognosis. Type I has the highest density but is associated with more challenging drilling and potential thermal necrosis if not properly irrigated.
