What is a common complication of dental implant placement?

• A. Gingivitis due to poor oral hygiene
• B. Bone loss resulting from excessive pressure
• C. Peri-implantitis if infections occur
• D. Failed local anesthesia

Answer: (C)

Peri-implantitis is a significant complication that can arise after dental implant placement, especially when infections occur. This condition is characterized by inflammation of the tissues surrounding the implant, leading to both soft tissue problems and bone loss. It typically results from bacterial infection, which can be exacerbated by poor oral hygiene practices, insufficient maintenance, or pre-existing periodontal disease. The presence of peri-implantitis can jeopardize the longevity and success of the dental implant, making it crucial for both practitioners and patients to monitor and maintain oral health around the implant site actively.

In contrast, while gingivitis and local anesthesia failures are issues that can occur in dental practices, they are not directly tied to complications arising specifically from dental implant placement. Also, while excessive pressure on the implant during its function can lead to bone loss, this scenario is more related to functional overload rather than an infection-related complication.
