Long-Term Management: Maintenance, Peri-Implant Disease, and Surveillance
Framework
Long-term management questions test surveillance and disease recognition. Know the distinction between peri-implant mucositis (reversible inflammation, no bone loss) and peri-implantitis (inflammation with progressive bone loss). Understand risk indicators: history of periodontitis, poor plaque control, smoking, uncontrolled diabetes, and lack of maintenance. Recall that probing depths, bleeding on probing, and radiographic bone levels are the core surveillance tools.
Maintenance protocols
Individualize recall intervals based on risk (e.g., 3-4 months for high-risk, 6 months for low-risk). Know the components of supportive peri-implant care: plaque control reinforcement, professional debridement with non-metallic instruments, restoration and occlusion checks, and radiographic monitoring. Recognize that implant survival is not the same as success - function, esthetics, and absence of disease matter.
Traps
Common distractors: treating peri-implant mucositis with surgery (it is managed nonsurgically); assuming a stable radiograph at one year means no further monitoring; or attributing mobility to bone loss when it may indicate loss of osseointegration. Another trap is overlooking cement retention as a cause of peri-implantitis.
Rule of thumb
Any bleeding on probing with increasing pocket depth should trigger radiographic review and a diagnosis of peri-implant disease until proven otherwise. Example: a patient with a history of periodontitis and a 7-mm pocket with bleeding at a 5-year recall - obtain radiographs, compare bone levels, and initiate nonsurgical therapy with closer recall before considering surgery.
