Clinical Study On Postoperative Complications Of Mandibular Third Molar Extraction With Groove Incision And Angled Incision

Objective:Comparing the Groove incision and the angle incision to remove the postoperative complications of the mandibular proximal and middle impacted third molars,to optimize the surgical incision for the extraction of the third impactor molar in the mandibular approach,and to provide clinical trial basis for postoperative complications.Methods: Case data from 2017.10 to 2018.10 studied at Zunyi Medical University,need to remove the third molar impacted third molar and meet the inclusion criteria of this study,100 college students,age 18-25 years,male or female,a total of 100 near the middle and lower jaw The third molar was implanted into the sulcus,and 50 patients were randomly divided into the groove incision group and 50 patients in the angled incision group.All patients underwent the same standard surgical operation and clinical treatment.The surgeon was the same senior physician to the mandibular ambush.The three molars were removed.Preoperative imaging of CBCT films to understand the relationship between the third molar and the adjacent teeth,the resistance,the relationship between the mandibular canal and the mandibular impacted third molar;measuring and recording the 6 sites of the mandibular second molar(near cheek),the midpoint of the buccal side,the far cheek,the near tongue,the proximal and middle points of the lingual side,the distal tongue,the depth of the periodontal probing,and the operation time of the operation(from the beginning of the incision to the end of the suture).The patients were recorded for opening,swelling,postoperative hemorrhage,mandibular fracture,inferior alveolar nerve injury,infection,etc.on the 2nd,5th and 8th postoperative day.The third month of the mandibular second molar was examined at 6 sites.The depth of the situation roughly evaluated the effect of the two incisions on the reattachment of the gums.Results:The degree of swelling was compared: the degree of swelling in the Groove incision group was significantly higher on the 2nd day and the 5th day after the operation(P<0.05),but there was no significant difference between the two groups on the 8th day after surgery(P>0.05);Degree comparison: The degree of opening restriction on the 2nd and 5th day after operation was more obvious than that of the Groove incision group(P<0.05),but there was no significant difference between the two groups on the 8th day after operation(P>0.05);Comparison of gingival reattachment: There was no significant difference in the depth of probing between the 6th and second mandibular molars before and after 3 months(P>0.05);postoperative hemorrhage: Groove incision group There were2 cases of post-bleeding and 13 cases of angular incision group.There were no infection,mandibular fracture and inferior alveolar nerve injury in this study.There was no significant difference in the duration of surgery between the two groups(P> 0.05).Conclusion:In the early postoperative stage,the Groove incision removed the mandibular ambush in the third molar,and the patient's satisfaction was higher.
