The aim of this study was to evaluate the implantation of powder-liquid mix type MTA, paste type MTA, and resin-based endodontic sealer (AH Plus) in tibia of rabbits for 12 weeks. Intraosseous implantation was tested according to ISO 10993-6:2016. After anesthesia, the cortical bone of tibia was exposed, then three or two holes were formed (2 mm in diameter × 6 mm in depth) in each side. The mixed materials according to manufacturer’s instruction were placed into the cylindrical holes. After implantation, all animals received visual inspection at least once a week and inflammation, complication, and other specific figures were recorded. All animals were euthanized 12 weeks after implantation, and the specimens received visual and histologic evaluation, then following results were obtained. New bone formation were most-abundant and uniformly in the experimental group of implantation of paste type MTA, and were observed to some extent in the experimental group of implantation of powder-liquid mix type MTA and microvascular invasion around MTA was examined. As the control groups of implantation of epoxy resin based endodontic sealer, severe lymphocytes and neutrophils were observed. Histologic evaluation revealed that both paste type MTA and powder-liquid mix type MTA were non-irritant compared with AH Plus that had no potential risk biologically, and were seemed to meet the criteria of implantation test. As the paste type MTA has similar physical and biological properties with better handling behavior, so powder-liquid mix type MTA can be substituted by the paste type MTA.
