✅ Pressure causes a decrease in blood flow, leading to bone resorption (osteoclasts); the tension side experiences increased blood flow and bone deposition (osteoblasts). surgical orthodontics

Growth modification appliances (like functional appliances or facemasks) only work on growing patients. If the question describes an adult, look for orthognathic surgery or camouflage options.

The applied force cuts off blood supply to the PDL, causing hyalinization, and bone is resorbed from the marrow side. D. The tooth moves too quickly. Answer: C Explanation: When excessive force is applied, the PDL is compressed to the point of occluding blood vessels (hyalinization).
