Association between CRP levels in systemic circulation and peri-implant bone loss

Area of Science:

• Dental Implantology
• Biomarkers in Oral Health
• Periodontology

Background:

• Peri-implant alveolar bone loss is a significant concern in dental implant success.
• C-reactive protein (CRP) is a systemic inflammatory marker.
• The relationship between preoperative CRP levels and early bone loss around implants requires further investigation.

Purpose of the Study:

• To investigate the association between high preoperative C-reactive protein (CRP) levels and early peri-implant alveolar bone loss.
• To evaluate the impact of elevated CRP on bone resorption adjacent to dental implants.

Main Methods:

• Retrospective analysis of 20 patients with high preoperative CRP levels (n=58 implants) and 20 patients with low CRP levels (n=54 implants).
• Measurement of vertical bone loss on mesial and distal sides relative to the implant platform.
• Statistical comparison using independent sample t test or Mann-Whitney U test, and correlation analysis with Spearman rho test.

Main Results:

• Patients with high CRP levels exhibited significantly greater mesial and distal peri-implant bone loss compared to the low CRP group (P < .05).
• A significant positive correlation was observed between preoperative CRP levels and both mesial and distal bone loss.
• Two implant failures occurred in the high CRP group.

Conclusions:

• Elevated preoperative C-reactive protein (CRP) levels are associated with an increased risk of early peri-implant alveolar bone loss.
• Preoperative CRP levels may serve as a valuable predictive marker for early bone loss around dental implants.
• Further research is warranted to explore the clinical implications of CRP in implant dentistry.
