Which of the following factors can be attributed to increased risk during dental implant surgery?

The presence of poor oral hygiene is a significant factor that increases the risk during dental implant surgery. When a patient has inadequate oral hygiene, it can lead to a higher accumulation of plaque and bacteria in the oral cavity. This creates an environment that is conducive to infections, which can complicate the healing process following implant placement. Dental implants rely on osseointegration, which is the process where the bone integrates with the implant. If the surrounding tissues are inflamed or infected due to poor oral hygiene, it can compromise this integration, leading to potential implant failure.

In contrast, non-smoker status, good nutrition, and regular dental check-ups tend to contribute positively to surgical outcomes. Non-smokers generally have better healing capabilities and reduced risks of complications, while good nutrition supports overall health and healing. Regular dental check-ups help maintain oral health and can catch potential issues before they affect surgical outcomes. Thus, maintaining good oral hygiene is essential before, during, and after dental implant surgery to minimize risks and ensure long-term success.
