Abstract:

Objective To investigate the efficacy of digital guide plate guided concentrated growth factor(CGF)combined with Bio-Oss bone powder for filling bone cavity after jaw cyst surgery. Methods Sixty patients who attended the Department of Oral and Maxillofacial Surgery of the Affiliated Stomatological Hospital of Xuzhou Medical University from September 2021 to September 2022 for jaw cyst removal were randomly divided into experimental group, control group 1 and control group 2. In the experimental group, a digital guide was made intraoperatively to locate the cyst and CGF combined with Bio-Oss bone powder was filled into the bone cavity. In the control group 1, a digital guide was made intraoperatively to locate the cyst and Bio-Oss bone powder was filled into the bone cavity, and in the control group 2, Bio-Oss bone powder was filled into bone cavity during the conventional surgery. Preoperative, 24 h and 72 h postoperative blood CRP and WBC levels and the time of surgery were measured. Postoperative pain level was assessed and postoperative bone mineral density values were measured 3 and 6 months after surgery. Results The postoperative CRP and WBC of the three groups were significantly higher than those before surgery. The postoperative inflammatory reaction, operation time and pain level of the experimental group and control group 1 were lower than those of control group 2, and postoperative inflammatory reaction was significantly lower in the experimental group than in control group 1. The bone density of bone defect area of the three groups 3 and 6 months after surgerywas higher than that before surgery, and the experimental group was significantly higher than the other two groups. Conclusion Digital guide plate guided CGF combined with Bio-Oss bone powder to fill the bone defect area after jaw bone cyst removal can shorten operation time, reduce postoperative inflammatory reaction and pain and discomfort, promote bone healing, improve osteogenesis speed and quality, and restore jaw bone morphology faster, which is worth being promoted in clinical application.
