Comparative study on the clinical application of minimally invasive high-speed turbo-drilling method and traditional cleft crown method in the treatment of mandibular low level impacted teeth
Objective:To compare and analyze the clinical effect of minimally invasive high-speed turbo-drilling method and traditional split-crown method in the treatment of mandibular low level impacted teeth.Methods:The clinical data of 113 patients with horizontal impacted mandibular teeth treated in our hospital from July 2020 to July 2022 were retrospectively collected.According to the difference of treatment regimen,the patients were divided into control group(58 cases were treated with traditional cleft crown method)and observation group(55 cases were treated with minimally invasive high-speed turbo-drilling method).The operation-related indexes(operation time,postoperative wound infection rate,pain assessment by Visual analogue scale(VAS))of the two groups were analyzed during and after the operation,and the fear adaptability and operation safety of the two groups were evaluated after the treatment.Digital quantification and finger quantification were used to observe and compare the complete mouth opening limitation of the two groups at 3 months,9 months and 12 months after operation.Results:The operation time of observation group was shorter than that of control group,and VAS score was significantly lower than that of control group(P<0.05).There was no significant difference in postoperative wound infection rate between the two groups(P>0.05).The number of 0° fear cases in observation group was significantly higher than that in control group,and the number of I° and Ⅱ° fear cases was significantly lower than that in control group(P<0.05).The total incidence of surgical complications in observation group was significantly lower than that in control group(P<0.05).The rate of complete mouth opening restriction in the observation group was lower than that in the control group at 3 months and 6 months after operation(P<0.05),and there was no statistical difference between the two groups at 12 months(P>0.05).Conclusion:High-speed turbodrill can improve patients'fear,relieve pain,shorten operation time,reduce postoperative complications and improve postoperative mouth opening limitation.
