摘　　要：目的:分析生物可吸收板内固定术在下颌骨骨折患者中的修复效果。方法:选取2021年8月-2022年8月于笔者医院接受治疗的98例下颌骨骨折患者为研究对象,依据手术方式不同分为两组。研究组50例采取生物可吸收板内固定术,对照组48例采取微型钛板固定术。评价两组治疗效果、固定应力及位移情况,比较两组手术前后的颞颌关节、咬合关系、张口度,并评价两组的并发症发生情况。结果:研究组的治疗优良率显著高于对照组(P<0.05);研究组的下颌骨、整体最大应力值、最大位移高于对照组,固定板最大应力值低于对照组,最大位移高于对照组(P<0.05);术后3个月,两组颞颌关节、咬合关系、张口度评分均降低,其中研究组各评分低于对照组(P<0.05);研究组的并发症发生率低于对照组(P<0.05)。结论:在下颌骨骨折患者的临床治疗中应用生物可吸收板内固定治疗效果显著,可明显提升骨应力,促进下颌骨功能恢复,改善颞颌关节、咬合关系及张口度,并发症少,对患者的下颌骨骨折有明显的修复作用。Objective To analyze the effect of absorbable plate internal fixation in mandibular fracture patients.Methods 98 patients with mandibular fracture who were treated in the author's hospital from eight 2021 to eightr 2022 were divided into two groups according to different surgical methods.50 cases in the study group were treated with bioabsorbable plate fixation,while 48 cases in the control group were treated with micro titanium plate fixation.To evaluate the treatment effect,fixation stress and displacement of the two groups,compare the temporomandibular joint,occlusion relationship,mouth opening degree of the two groups before and after surgery,and evaluate the complications of the two groups.Results The excellent and good rate of treatment in the study group was significantly higher than that in the control group(P<0.05).The maximum stress and displacement of the mandible and the whole body in the study group were higher than those in the control group,while the maximum stress value of the fixed plate was lower than that of the control group,and the maximum displacement was higher than that of the control group(P<0.05).Three months after operation,the scores of temporomandibular joint,occlusal relationship and mouth opening in both groups decreased,and the scores in the study group were lower than those in the control group(P<0.05).The incidence of complications in the study group was lower than that in the control group(P<0.05).Conclusion In the clinical treatment of patients with mandibular fracture,the application of bioabsorbable plate internal fixation has a significant effect,which can significantly enhance the bone stress,promote the recovery of mandibular function,improve the temporomandibular joint,occlusion relationship and mouth opening degree,with fewer complications,and has a significant repair effect on patients with mandibular fracture.
