Abstract:

BACKGROUND: Heal-all oral biofilm is a material utilized in repairing oral mucosa and soft tissues defects and characterized by degradation, easily preparation, long preserved duration, convenient transportation and good ossification, which has been widely used in dental implant as guided bone regeneration materials.
OBJECTIVE: To check the clinical effective of Heal-all oral biofilm on guided bone regeneration in dental implant.
METHODS: A total of 72 patients with bone defects in the implantation area were selected as subjects, who were divided into control group and experimental group at random. Bone defects around implants were repaired by guided bone regeneration technique with BME-10X medical collagen membrane and Heal-all oral biofilm respectively. X-ray and clinical examination were taken at 1 and 3 months after implantation. The amount of new-formed bone tissue was evaluated when stage II operation was performed.
RESULTS AND CONCLUSION: In stage II operation, osseointegration was formed between implants and bone tissue in all 72 patients. The average rate of bone formation was 92% in the experimental group while 91% in the control group. All implants were successfully repaired with implant denture. Occlusal function was restored successfully with all 72 implants during the follow-up period of 3-24 months after restoration. As an alternative option of BME-10X medical collagen membrane, Heal-all oral biofilm can be used in guided bone formation clinically.
