INBDE (Integrated National Board Dental Examination) 2026 – 400 Free Practice Questions to Pass the Exam

The mandible, or jawbone, consists of two primary types of bone formation - endochondral and intramembranous. This means that the bone formed in the jaw develops through two distinct processes - one of which occurs in the cartilage and the other in the membrane. Therefore, options B, C, and D are incorrect because they do not accurately describe the types of bone formation present in the mandible. Option B refers to a type of cartilage found at the ends of long bones, while options C and D both refer to types of tissues that are not specifically involved in jawbone formation.
