Study on Effect Difference between Triangular Incision and Envelope Incision in the Extraction of Horizontal Mandibular Impacted Wisdom Teeth
Objective:To compare the effects of envelope incision and triangular incision for extraction of horizontal mandibular impacted wisdom teeth on masticatory function,mouth opening limitation,pain and swelling of patients.Method:The clinical data of patients with horizontal mandibular impacted wisdom teeth who underwent envelope incision for extraction in Ji'an Hospital,Shanghai Oriental Hospital from November 2021 to February 2023 were retrospectively analyzed,and 38 patients(38 affected teeth)were randomly selected and included in envelope group.The clinical data of patients who received triangular incision for extraction of horizontal mandibular impacted wisdom teeth in the hospital during the same period were retrospectively analyzed,and 30 patients(30 affected teeth)were randomly enrolled as triangular group.The surgical indicators(surgical time,intraoperative blood loss),limitation of mouth opening,pain and swelling on the 7th day after surgery and masticatory function(occlusal force,masticatory efficiency)at 1 month after surgery were compared between the two groups of patients,and the adverse events within 1 month after surgery were counted.Result:There were no statistically significant differences in the surgical time and intraoperative blood loss between envelope group and triangular group(P>0.05).On the 7th day after surgery,the pain and swelling and limitation of mouth opening in envelope group were severer than those in triangular group,with statistical differences(P<0.05).At 1 month after surgery,the occlusal force and masticatory efficiency in envelope group were lower than those in triangular group,with statistically significant differences(P<0.05).Within 1 month after surgery,there was no statistical significance in the total incidence rate of adverse events between the envelope group(26.32%)and the triangular group(23.33%)(P>0.05).Conclusion:Envelope incision and triangular incision in extraction of horizontal mandibular impacted wisdom teeth can achieve good clinical therapeutic effect and good safety.However,triangular incision for extraction can effectively alleviate postoperative limited mouth opening and pain swelling in patients,which is beneficial for the recovery of their chewing and biting abilities.
