Analysis has proven that titanium particles might happen in infected tissues round dental implants. However a brand new examine, printed in Communications Medication, confirmed that titanium micro-particles are discovered in any respect examined implants, with or with out indicators of irritation.
Tord Berglundh, senior professor of periodontology at Sahlgrenska Academy, College of Gothenburg, instructed Medical Xpress that titanium is a “well-studied materials that has been used for many years.”
“It’s biocompatible and protected, however our findings present that we have to higher perceive what occurs to the micro-particles over time. Do they continue to be within the tissue or unfold elsewhere within the physique?” mentioned Berglundh.
After analyzing samples of human comfortable tissue taken from implant websites with and with out peri-implantitis, the examine by the College of Gothenburg and Uppsala College additionally recognized 14 genes which may be affected by these particles.
“However it’s unclear whether or not the particles affect the native immune response or if the distinction in gene expression displays inter-individual variability in inflammatory situations,” says Carlotta Dionigi, specialist in periodontology and researcher on the Division of Periodontology, Sahlgrenska Academy, College of Gothenburg.
