简要总结
Adverse events: Evaluation of safety: In terms of the quality control of the product, no problem was observed. No adverse events related to cell transplantation was observed. The exposure of GBR membrane was observed in 3 cases, which was healed after removal of the membrane and bone regeneration was feasible. Overall, the safety of this protocol was confirmed. Efficacy: New bone area was identical to that in the preceding our clinical study. Individual variation (cell proliferation and new bone area) was significantly reduced from previous clinical study. All dental implants aquired ossointegration and no failure was observed during the observation period. Evaluation: The results showed the safety of this protocol. The level of new bone formation was identical to that of the previous clinical study, thus proved the non-inferiority of the current protocol. Since the purpose of this study has achieved from 15 cases, the clinical study was closed without the addition of 10 cases, which was originally planned.
