You are performing a 5-year follow-up on a 43-year-old implant patient. When comparing radiographs you estimate that there has been almost 0.1 mm loss of bone height around the implant since it was placed. Which of the following is indicated?

**Core Concept**
The loss of bone height around an implant is a common complication, and it can be due to various factors such as peri-implantitis, occlusal overload, or biological width. The management of this condition depends on the extent of bone loss, the presence of symptoms, and the overall health of the implant and surrounding tissues.

**Why the Correct Answer is Right**
Bone loss of 0.1 mm around an implant is considered minimal, and it may not be clinically significant. Since there are no symptoms or signs of peri-implantitis, such as bleeding on probing or increased pocket depth, the patient can be monitored for a longer period. The correct answer is therefore to continue with regular maintenance and monitoring.

**Why Each Wrong Option is Incorrect**
* **Option A:** Immediate surgical intervention is not indicated for minimal bone loss without symptoms.
* **Option B:** No treatment is necessary for a healthy implant with minimal bone loss.
* **Option C:** Antibiotics are not indicated unless there is a clear sign of infection or peri-implantitis.

**Clinical Pearl / High-Yield Fact**
In implant dentistry, the biological width around an implant is crucial for the long-term success of the implant. The biological width is the distance between the implant surface and the surrounding bone, and it should be maintained to prevent peri-implantitis.

**Correct Answer: B. No treatment is necessary for a healthy implant with minimal bone loss.**

✓ Correct Answer: D. The implant is doing well; this amount of bone loss is considered acceptable.
