目的:探讨超声骨刀(UBK)联合牙科电动马达(DEM)在下颌中低位埋伏牙拔除术中的临床应用。
方法:将2022年1月至2023年5月的200例智齿患者随机分为3组:实验组A(UBK联合DEM),实验组B(UBK结合高速涡轮手机(HSTMP)),对照组(骨凿劈冠(BCSC))。操作时间,手术期间的心理状态,疼痛,肿胀,限制张口和其他并发症的第一,记录术后第二天和第三天。
结果:实验组A(EAG)手术时间(12.95±2.12)分钟短于实验组B(EBG)(17.06±2.25)分钟及对照组(CG)(23.43±2.18)分钟,差异有统计学意义(P<0.05)。EAG的心理状况显著低于EBG和CG(P<0.05)。术后疼痛,肿胀,EAG的张口限制和并发症明显低于EBG和CG(P<0.05)。
结论:UBK联合DEM在下颌中下段阻塞牙拔除术中有较好的效果,预后良好,安全性高,操作时间短,患者的心理状况更好,术后疼痛低,肿胀,张口限制和并发症发生率,是目前首选的提取方法。
To investigate the clinical application of an ultrasonic bone knife (UBK) combined with a dental electric motor (DEM) in the extraction of mandibular middle and low impacted teeth.
From January 2022 to May 2023,200 patients with wisdom teeth were randomly divided into three groups: experimental group A (UBK combined with DEM), experimental group B (UBK combined with high-speed turbine mobile phone (HSTMP)), and the control group (bone chisel split crown (
BCSC)). The operation time, psychological state during operation, pain, swelling, limitation of mouth opening and other complications on the first, second and third days after operation were recorded.
The operation time of experimental group A (EAG) (12.95 ± 2.12) minutes was shorter than that of experimental group B (EBG) (17.06 ± 2.25) minutes and the control group (CG) (23.43 ± 2.18) minutes, and the difference was statistically significant (P < 0.05). The psychological state of the EAG was significantly lower than that of the EBG and CG (P < 0.05). The postoperative pain, swelling, limitation of mouth opening and complications in the EAG were significantly lower than those in the EBG and CG (P < 0.05).
UBK combined with DEM in the extraction of mandibular middle and low obstructed teeth has good results, good prognosis, high safety, short operation time, better psychological status of patients, low postoperative pain, swelling, mouth opening restriction and complication rate, and is currently the preferred extraction method.
