Outline of Final Research Achievements

Implant designs that can stimulate and integrate with an epithelial wound healing process may significantly enhance the efficacy of dental implants. Here, we investigated the effect of systemic Mesenchymal Stem Cells (MSC) transplantation on peri-implant epithelial sealing. Systemic MSC transplantation may be effective for enhancing epithelial sealing around titanium implants.In addition, the peri-implant epithelium condition on the implant body was investigated in vitro study. Rat oral epithelial cells (OECs) were co-cultured with MSC. We also identified an increase in the number of attached OECs upon direct or indirect co-culture with MSCs, and OEC apoptosis increased in co-culture with MSCs.
Collectively, our data suggest that systemic MSCs accumulate around the implant in the early stage and promote PIE formation and soft tissue attachment to the implant surface.
