Abstract:

BACKGROUND: Current treatments of peri-implantitis include surgery, laser therapy, ultrasonic scaling, local medication or their combination. However, there have been no ideal therapeutic effects achieved.
OBJECTIVE: To investigate the feasibility of treating peri-implantitis using tissue-engineered bone reconstructed by bone morphogenetic protein-modified adipose-derived stem cells and Bio-oss scaffold.
METHODS: A computer-based online retrieval of Pubmed database was performed to search papers published during January 1988 to December 2011 using the key words “adipose-derived stem cells, tissue engineering” in English. Simultaneously, related papers published during January 2005 to December 2011 in CNKI were retrieved using the key words “adipose-derived stem cells, tissue engineering” in Chinese. A total of 56 papers were retrieved.
RESULTS AND CONCLUSION: According to the characteristics and advantages of regenerative tissues in tissue engineering, a three-dimensional environment was established using adipose-derived stem cells as ideal seed cells, bone morphogenetic protein 2 as an ideal cytokine and Bio-oss biomaterial. The multiporous structure of Bio-oss biomaterial facilitates the migration of adipose-derived stem cells. After compounded by adipose-derived stem cells, bone morphogenetic protein 2 promotes osteogenic differentiation of adipose-derived stem cells, leading to new bone formation by deposition of calcium salt and achieving the purpose of treating peri-implantitis.
