Abstract：Objective To study the clinical effect of digital guide plate combined with bone slice preservation technology in the treatment of jaw cysts.Methods Totally forty patients who needed jaw cyst enucleation in the outpatient depart-ment of oral surgery of the First Affiliated Hospital of Xinjiang Medical University(Affiliated Stomatological Hospital)from October 2023 to October 2024 were randomly divided into the study group and the control group(20 cases in each group).In the study group,digital guide plate combined with bone slice preservation technology was used during cyst enucleation,and concentrated growth factors(CGF)were filled;the control group was treated with conventional cyst enu-cleation and then CGF were filled.The operation time,the content of C-reactive protein(CRP)and white blood cell(WBC)at 1 d before operation and 1 d and 3 d after opera-tion,the visual analogue scale(VAS)score of pain at 1 d,3 d and 7 d after operation,the Landry wound healing in-dex at 3 d,7 d and 14 d after operation,the degree of post-operative swelling,complications and recurrence at 1 year after operation,the gray value of bone mineral density in the operation area before operation and at 3 months,6 months and 12 months after operation,and the volume of lesion bone cavity before operation and at 6 months and 12 months after operation were compared between the two groups.Re-sults The operation time was(31.40±5.34)min in the study group and(29.40±4.78)min in the control group,and there was no significant difference between the two groups(t=1.247,P=0.220).There was no significant difference in the preoperative CRP and WBC content,gray value of bone mineral density in the operation area,or volume of lesion bone cavity between the two groups(all P＞0.05);in the study group,the CRP content at 1 d after operation and the volume of the lesion bone cavity at 6 months and 12 months after operation were significantly reduced compared with the control group,and the gray value of bone mineral density at 3 months and 6 months after operation was significantly increased compared with the control group,with statistically significant differences(all P＜0.05).Compared with the control group,the VAS score of the study group at 1 day and 3 days after operation was significantly reduced,and the Landry wound healing index at 7 days and 14 days after operation was significantly increased,with statistically significant differences(all P＜0.05).There was no significant difference in the degree of postoperative swelling,complications or recurrence at 1 year after operation between the two groups(all P＞0.05).Conclusion Digital guide plate combined with bone slice preservation technology in the treatment of jaw cysts can achieve precise positioning,reduce surgical trauma,reduce post-operative pain,and help the soft and hard tissue healing in the operation area,which is worthy of clinical application.
