Key inclusion criteria

Subjects were patients who planned to receive dental implant treatment. These subjects had continuous tooth defects (more than 2), where fixed prostheses were not applicable. The subjects voluntarily enrolled in this study and wished to have dental implant treatment rather than conventional removable prostheses. Subjects showed severely atrophic maxilla or mandible, which require bone transplantation. The width of alveolar bone at the installation sites was less than 5 mm. In the maxilla, the distance between the alveolar ridge and the sinus floors was less than 5 mm. Similarly, in the mandible, the distance between the ridge and mandibular canal was less than 5 mm. Good oral hygiene was maintained. Tooth brushing instruction and scaling were performed prior to the protocol treatment. The age of the subjects was limited to 20 -70 years. The subjects were able to understand and agreed to receive the treatment by informed consent.

Key exclusion criteria

Patients with diabetes and/or autoimmune diseases, who presented hemorrhagic diathesis where partial thromboplastin time (PT) was lower than 50% and activated partial thromboplastin time (APTT) less than 23.5 or longer than 42.5 seconds, uncontrollable infectious diseases, patients with osteoporosis who are prescribed bisphosphonate, liver dysfunction with a Glutamic Oxaloacetic Transaminase (GOT) value less than 10 or more than 40 IU/L or with a glutamic pyruvic transaminase (GPT) less than 5 or more than 45 IU/L, pregnant or possible pregnancy, allergy to any of the medications used in this study and/or the presence of allergy that required continuous systemic medication, smokers, subjects who are positive for HBs antigen (CLIA), HBs antibody (CLIA), HBc antigen (CLIA), HCV antibody (RIA solid phase), HIV antigen and HIV antibody (ELISAs), syphilis serology (RPR), syphilis serology (TPHA) and HTLV-1 and other special conditions that the responsible physician considered not appropriate were excluded.

Results

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.
