Abstract:
Objective:To explore the effect of ultrasound bone knife combined with high-speed gas turbine method in mandibular impacted third molar extraction surgery,and conduct relevant analysis for bleeding situation.Methods:A total of 152 patients who underwent mandibular impacted third molar extraction surgery at Beijing First Hospital of Integrated Traditional Chinese and Western Medicine from April 2023 to April 2024 were retrospectively selected.They were divided into an observation group and a control group based on the different types of used instruments during the operation,with 76 cases in each group.The observation group used ultrasound bone knife combined with high-speed gas turbine method,while the control group only used high-speed gas turbine.The general information,incidence of intraoperative complications,surgical time,visual analogue scale(VAS)for pain assessment,degree of alveolar damage,patient's satisfaction,the number of patients with postoperative complications,intraoperative bleeding volume,postoperative bleeding time,and hemostatic effect were compared between two groups.Results:The incidence of complications included loosening of adjacent tooth,fracture or displacement of adjacent tooth,root fracture,and fracture of lingual bone plate in the observation group was 11.84%,which was lower than 23.68%in the control group,and the difference was statistically significant(x2=3.958,P＜0.05).Both the surgical time and VAS score of the observation group were lower than those of the control group(t=-7.875,-3.222,P＜0.05),and the degree of alveolar damage and the number of patients with postoperative complications in the observation group were significantly lower than those in the control group,with statistically significant differences(t=-6.500,x2=4.417,P＜0.05).The average score of patients'treatment satisfaction in the observation group was significantly higher than that in the control group(t=4.242,P＜0.05).Both the intraoperatively blooding loss and the time of postoperative bleeding in the observation group were significantly lower than those in the control group(t=-3.636,-9.191,P＜0.001),and the score of hemostasis effect in the observation group was also better than that in the control group(t=11.744,P＜0.001).Conclusion:The effect of ultrasound bone knife combined with high-speed gas turbine method is better for mandibular impacted third molar extraction surgery,which performance is better in the amount of intraoperative bleeding loss,the time of postoperative bleeding,and hemostatic effect.
