Dental Implant Techniques and Outcomes

Neutrophil collagenase or collagenase-2 (matrix metalloproteinase [MMP]-8) belongs to the collagenase subgroup of the MMP superfamily of calcium- and zinc-dependent neutral proteinases. MMP-8 is catalytically the most competent proteinase to initiate type I collagen and extracellular matrix degradation associated with periodontal and peri-implant tissue destruction leading to tooth and dental implant loss. Regarding cardiovascular diseases, pathologically excessive MMP-8 has been implicated in atherosclerotic plaque destabilization and rupture probably through its proteolytic ability to thin the protecting collagenous fibrous cap lining coronary and other arteries. During the initiation and course of inflammatory responses in periodontitis, peri-implantitis and cardiovascular diseases, proinflammatory mediators including especially MMP-8 are up-regulated not only in affected tissues but also in the secreted, disease-affected, oral fluids (gingival crevicular fluid [GCF], peri-implant sulcular fluid [PISF], mouthrinse and saliva) as well as in serum and plasma. Regarding periodontitis, peri-implantitis and cardiovascular diseases, the oral fluid and serum MMP-8 analysis has proven to be a sensitive and an objective biomarker as an indicator of health, pathologic processes and pharmacologic response to therapeutic intervention including doxycycline medication as an MMP inhibitor. Oral fluids, i.e., GCF, PISF, mouthrinse and saliva are easily and non-invasively collected for the site- and patient-specific diagnostic analysis in periodontitis and peri-implantitis, whereas serum and/or plasma sample collection is required for diagnosis and monitoring of cardiovascular diseases. Research in periodontology and cardiology has identified a need for the development of innovative point-of-care diagnostic tests for MMP-8. We summarize and review the recent studies on these topics.
