摘要: Objectives Dental peri-implantitis is characterized by a multifactorial etiology. The role of metal elements as an etiological factor for still unclear. aim this study was to investigate the incidence in bone and mucosal tissues around dental Grade 4 CP titanium implants with signs human patients. Methods In prospective pilot study, all patients were enrolled consecutively two centers. Bone soft tissue samples indication explantation analyzed different (Ca, P, Ti, Fe) means synchrotron radiation X-ray fluorescence spectroscopy (SRXRF) polarized light microscopy (PLM). existence macrophages lymphocytes histologic specimens analyzed. Results Biopsies 12 (seven samples, five samples) included analyzed. In nine (75%), SRXRF examination revealed (Ti) associated occurrence Iron (Fe). Metal particles detected peri-implant using PLM. increased concentration, detected, whereas M1 predominantly seen particles. Conclusion Titanium found hard biopsies retrieved from sites. Further immunohistochemical studies need clarify which specific immune reaction elements/particles induce tissue.
