涡轮机联合微创拔牙器械在拔除低位阻生智齿中的临床应用 postprint

Abstract: Objective To compare the clinical application of extraction of mandibular impacted wisdom teeth under turbinecombined minimally invasive extraction instrument method and traditional method of tooth extraction. The advantages anddisadvantages were compared. Methods Eighty-two cases with low mandibular impacted wisdom teeth were selected. Theywere randomly divided into experimental and control group, with 41 cases in each group. Experimental group was performedwith minimally invasive tooth extraction knife tooth extraction in combining with the high speed turbine dental drill toothextraction. Control group was performed with traditional tooth extraction equipment. Increased rate, rate of incomplete toothextraction sockets, dental fear of disease incidence rate, operation time and postoperative mouth by the limit of differenceswere compared. Results The experimental group was healed in primary, whereas the control group had 4 cases with delayedhealing caused by infection. The rate of root fracture in experimental group was 7.3%, while the control group was 22%. Noneof experimental group had incompleted of tooth extraction socket, while the control group had 18 cases with incomplete toothextraction socket. Two cases in experimental group had dental fear of disease, while 5 cases in the control group. Comparedwith control group, operation time decreased significantly and postoperative mouth was lighter in experimental group(P<0.05). Conclusion Compared to traditional method of tooth extraction, the minimally invasive tooth extraction technologyin the mandibular impacted wisdom teeth low urethral surgery are painless, safe and minimally invasive. It has a good clinicalapplication prospects.
