The phase of healing focused on tissue strengthening and remodeling is which?

• A. Hemostasis and inflammation
• B. Epitheliazation
• C. Proliferation
• D. Remodeling

Answer: (D)

Remodeling, also called maturation, is the phase where the wound gains tensile strength and the tissue becomes more organized. After the initial clotting and inflammatory cleanup, and the proliferative phase that builds new tissue and blood vessels, remodeling reorganizes and cross-links collagen fibers so they align along lines of stress. Over time, weaker type III collagen is replaced by stronger type I collagen, and the scar becomes less cellular and less vascular as it matures. This ongoing process explains why strength continues to increase for weeks to months after the injury.
