Abstract: PURPOSE: To verify the efficacy and safety of calcined cattle bone grafting material in filling alveolar bone defect after tooth extraction. METHODS: A randomized, bind, parallel, positive-control multicenter clinical trial was conducted. A total of 280 subjects were randomly assigned to either the experimental group (calcined cattle bone group) or control group (Bio-Oss group) equally. The main efficacy indicator was the imaging changes 24 weeks after material implantation. Secondary efficacy indicators were wound healing, rejection, bone metabolism, post-filling symptoms and signs of bone infection. The safety of material was assessed by the incidence of adverse events and serious adverse events. SAS 8.2 software package was used for statistical analysis. RESULTS: A total of 280 cases were included, of them 267 cases completed the study while 13 cases fell off. The effective rate of FAS(PPS) was 90.58%(97.46%) in the experimental group and 87.05% (95.04%) in the control group. The difference of effective rate between the experimental group and control group (95%CI) was 3.53% (-3.88%, 10.94%) of FAS, 2.42% (-2.38%, 7.22%) of PPS, and there was no significant difference between the two groups. The incision healing of the two groups was good, and the incidence of rejection, bone infection signs, post-filling symptoms and bone metabolic changes was very low. The incidence of adverse events was similar in the two groups, and no serious adverse events related to the study materials occurred. CONCLUSIONS: The efficacy of calcined cattle bone grafting material in filling alveolar bone defect after tooth extraction is not inferior to that of Bio-Oss, and it is safe and effective for alveolar bone defect repair.
