Edentulism of Maxilla (Upper Jaw) Maxilla Bone Regeneration

Bone regeneration with autologous bone marrow cells (CO2-1) and bovine bone mineral (Bio-Oss®) in surgical treatment of upper jaw edentulism

Objectives

Clinical trial to assess the safety and find evidence of efficacy of treatment with expanded mesenchymal stem cells grafts for maxillary bone regeneration.

Methodology 

Phase I-II, open-label, prospective and unicentric clinical trial.

A graft consisting of expanded bone marrow mesenchymal stem cells was implanted in bovine bone biomaterial.

Results

Safety
The procedure proved effective, no adverse or toxic effects were recorded.

Efficacy
A higher quality of newly formed bone tissue was evident in the areas where the biograft was implanted with expanded mesenchymal stem cells, compared to the control areas where only biomaterial was implanted.

Conclusions

The therapy is safe and effective. Implantation of a biograft with expanded mesenchymal stem cells improves bone quality and could be beneficial in patients with progressive maxillary atrophy due to loss of dental pieces that require implant application.
