Which statement below is incorrect regarding the alveolar bone?

Explanation

Option A is correct because the alveolar bone proper surrounds the root and anchors the periodontal ligament fibers. Option B is true as the supporting alveolar bone surrounds the alveolar bone proper and stabilizes the socket. Option C is accurate since the cortical plates are thinner in the maxilla than in the mandible. Option D is incorrect because the cortical bone is actually thickest in the posterior region of the jaw, not the anterior.
