3D打印负压引流塞治器在颌骨囊肿开窗减压术中的应用效果

Application effects of 3D printing negative pressure drainage obturator in fenestration decompression of patients with jaw cysts

目的:观察3D打印负压引流塞治器在颌骨囊肿开窗减压术中的应用效果。方法:回顾性分析2021—2022年该院收治的60例颌骨囊肿患者的临床资料,按照所用塞治器不同将其分为对照组和研究组各30例。对照组采用传统义齿型负压引流塞治器,研究组采用3D打印负压引流塞治器。比较两组术后不同时间囊腔体积缩小率,临床疗效,塞治器满意度评分,以及并发症发生率。结果:研究组术后3、6个月囊腔体积缩小率均高于对照组,差异有统计学意义(P<0.05);研究组治疗总有效率为96.67%(29/30),高于对照组的73.33%(22/30),差异有统计学意义(P<0.05);研究组固位性、舒适性、使用便利性、易清洁性等塞治器满意度评分均高于对照组,差异有统计学意义(P<0.05);研究组并发症发生率为3.33%(1/30),低于对照组的26.67%(8/30),差异有统计学意义(P<0.05)。结论:3D打印负压引流塞治器应用于颌骨囊肿开窗减压术可提高囊腔体积缩小率、治疗总有效率和塞治器满意度评分,降低并发症发生率,效果优于传统义齿型负压引流塞治器。

Objective:To observe application effects of 3D printing negative pressure drainage obturator in fenestration decompression of patients with jaw cysts.Methods:The clinical data of 60 patients with jaw cysts admitted to this hospital from 2021 to 2022 were retrospectively analyzed.According to the different obturators used,they were divided into control group and study group,30 cases in each group.The control group was treated with traditional denture negative pressure drainage obturator,while the study group was treated with the 3D printing negative pressure drainage obturator.The cyst cavity volume reduction rate at different time after the surgery,the clinical efficacy,the obturator satisfaction score,and the incidence of complications were compared between the two groups.Results:The cyst cavity volume reduction rate in the study group was higher than that in the control group 3 and 6 months after the surgery,and the difference was statistically significant(P<0.05).The total effective rate of treatment in the study group was 96.67%(29/30),which was higher than 73.33%(22/30)in the control group,and the difference was statistically significant(P<0.05).The satisfaction scores of retention,comfort,convenience and easy cleaning in the study group were higher than those in the control group,and the differences were statistically significant(P<0.05).Further,the incidence of complications in the study group was 3.33%(1/30),which was lower than 26.67%(8/30)in the control group,and the difference was statistically significant(P<0.05).Conclusions:The 3D printing negative pressure drainage obturator in fenestration decompression for the patients with jaw cysts can improve the cyst volume reduction rate,the total effective rate of treatment and the obturator satisfaction score,and reduce the incidence of complications.Moreover,it is superior to traditional denture negative pressure drainage obturator.
