Connective tissue around implants avoids which condition?

• A. Gingival recession
• B. Caries
• C. Peri-implantitis
• D. Osteoporosis

Answer: (C)

The key idea is that a healthy connective tissue around implants acts as a biological barrier that helps prevent inflammatory disease of the surrounding tissues. Peri-implantitis is inflammation around an implant with progressive bone loss caused by bacterial plaque; when the soft tissue surrounding the implant is healthy and forms a stable seal, it helps restrict bacteria from reaching the bone and reduces the risk of this inflammatory destruction. In contrast, gingival recession relates to the position and thickness of the gum margin, caries involves tooth surfaces (not present on implants), and osteoporosis concerns bone density more than the soft-tissue seal—so they aren’t the conditions primarily prevented by the surrounding connective tissue around implants.
