Aim To analyse change in selected bone markers in peri‐implant sulcus fluid ( PISF ) sampled before treatment and after 12 months and test correlation with change in disease progression. Materials and Methods Peri‐implant sulcus fluid was sampled from 32 patients in a randomized, clinical study comparing peri‐implant defect re‐construction with or without porous titanium granules. Matrix metalloproteinase 8 levels were measured using the Quantikine Human Total MMP ‐8 ( DMP 800) ELISA . Multianalyte profiling of the level of bone markers [interleukin‐6, osteprotegerin (OPG), osteocalcin, leptin, osteopontin, parathyroid hormone, tumour necrosis factor‐α, adiponectin and insulin] was performed by Luminex using Human Bone Panel IB . Changes in bone marker levels were compared and correlation with clinical findings was tested. Results No differences in clinical parameter or bone marker levels between test and control group were found. When comparing bone marker levels irrespective of treatment allocation between baseline and 12 months, a significant reduction in total protein, matrix metalloproteinase ‐8, interleukin‐6, OPG, leptin and adiponectin were demonstrated. Positive correlations were found between the reduction in interleukin‐6 ( r = 0.43), insulin ( r = 0.38) and matrix metalloproteinase‐8 ( r = 0.47) concentration, and probing pocket depth reduction. Conclusion Peri‐implantitis surgical treatment induced some reduction of the studied bone markers. Conclusive evidence for correlation between change in bone marker concentrations with disease resolution was not found.
