摘要
背景:生物可吸收性微型接骨板植入后患者恢复较好,且效果与微型钛内固定相似,并且由于其可吸收性,不会作为异物长期存在体内,无需二次手术,并且不影响骨的应力,不会出现骨组织萎缩的现象,并发症较传统金属内固定少。目的:比较微型钛内固定系统与生物可吸收性微型接骨板对下颌骨骨折稳定性的影响。方法:选取自2013年1月至2015年5月海南省人民医院口腔科门诊收治的90例下颌骨骨折患者作为研究对象,根据固定所用材料不同分为微型钛组与生物可吸收组。微型钛组患者采用微型钛固定系统内固定骨折,生物可吸收组患者采用生物可溶性微型接骨板内固定骨折部位。结果与结论:生物可吸收组患者内固定后3个月骨折稳定的良好率明显高于微型钛组;微型钛组患者内固定后颞下颌关节功能和内固定后1年髁状突移动的幅度明显高于可吸收组。结果说明2种方法治疗下颌骨骨折均有良好临床疗效。但微型钛内固定操作简单,稳定性较好,可吸收性内固定可以减少异物对机体的反应防止骨质疏松,联合颌间牵引后其稳定性也较为理想。因此临床应用哪一种材质进行内固定应视病变情况及患者意愿决定。
BACKGROUND： Bioabsorbable miniplates have good achievements after implantation, which have similar effect to the miniature titanium fixation system. Due to its absorbability, the bioabsorbable miniplate cannot exist in the body for a long time, which cannot influence bone stresses, cannot result in bone tissue atrophy, and have fewer complications than traditional metal internal fixations. OBJECTIVE： To explore and analyze the effects of miniature titanium internal fixation system versus bioabsorbable miniplates on fracture stability in patients with mandibular fractures. METHODS： Ninety patients with mandibular fractures admitted at the Department of Stomatology, Hainan General Hospital from January 2013 to May 2015 were enrolled. All the subjects were divided into two groups according to different internal fixations： miniature titanium group and bioabsorbable miniplate group. RESULTS AND CONCLUSION： At 3 months after internal fixation, the stability rate was significantly higher in the bioabsorbable miniplate group than the miniature titanium group. At 1 year after internal fixation, the range of motion of the processus condyloideus was significantly higher in the miniature titanium group than the bioabsorbable miniplate group. These findings suggest that the bioabsorbable miniplate and miniature titanium internal fixation system both have good clinical outcomes in the treatment of mandibular fractures. The miniature titanium internal fixation system is easy to use and has good stability; the bioabsorbable miniplate can reduce foreign body reaction and prevent osteoporosis, and it has an ideal stability in combination with intermaxillary traction. Therefore, what kind of internal fixations is selected should be determined based on the willingness and conditions of patients.
