Effect of bioabsorbable plate on fixation stress and displacement in patients with open reduction and internal fixation of mandibular fracture
Objective To explore the effect of bioabsorbable plate on fixation stress and displacement in patients with open reduction and internal fixation of mandibular fracture.Methods A total of 90 patients with mandibular fracture treated by open reduction and internal fixation in our hospital from August 2019 to August 2022 were selected as the research objects.The patients were divided into control group and observation group by random number table method,with 45 cases in each group.The control group was fixed with micro titanium plate,and the observation group was fixed with bioabsorbable plate.The therapeutic effects of the two groups were compared.Results The excellent and good rate of treatment in the observation group was higher than that in the control group(P<0.05).The maximum stress value and maximum displacement value of the mandible,the whole and the fixed plate in the observation group were better than those in the control group(P<0.05).The occlusal relationship of the observation group was better than that of the control group(P<0.05).The total incidence of complications in the observation group was lower than that in the control group(P<0.05).After operation,the levels of interleukin-6(IL-6)and C-reactive protein(CRP)in the observation group were lower than those in the control group(P<0.05).Conclusion Bioabsorbable plate fixation can improve the therapeutic effect of patients with open reduction and internal fixation of mandibular fracture,improve the fixation stress and displacement,enhance the stability of fracture,reduce the occurrence of complications and alleviate the inflammatory response,which is worthy of promotion.
