What is the body's attempt to isolate the implant as it degrades or leaches components?

• A. Fibrous capsule
• B. Granulation tissue
• C. Calcified barrier
• D. Scarring

Answer: (A)

Fibrous capsule formation is the body's response to isolate a degrading or leaching implant. When a foreign material is present, the body mounts a foreign body reaction and coats the implant with dense connective tissue rich in collagen, creating a capsule that physically walls it off from surrounding tissues. This barrier helps limit direct contact and slows diffusion of any components released as the implant degrades. Early healing may involve granulation tissue, but that is part of the initial inflammation and healing process and typically matures into the fibrous capsule. A calcified barrier is not the usual isolating mechanism, and while scarring describes fibrous tissue formation, the specific isolating structure around an implant is the fibrous capsule.
