人工骨表面覆盖口腔修复膜对颌骨囊性缺损人工骨植入术患者植入腔感染的预防作用

目的:探讨人工骨表面覆盖口腔修复膜对颌骨囊性缺损人工骨植入术患者植入腔感染的预防作用。方法:将我院2012年4月～2016年2月收治的78例颌骨囊性缺损患者按治疗时间分为对照组38例与观察组40例,均行开窗人工骨植入术,其中对照组采取常规抗感染,观察组采取人工骨表面覆盖口腔修复膜。比较两组的囊腔体积、面积缩减率、人工骨植入量、骨厚度及植入腔感染率。结果:两组的囊腔体积、面积缩减率及人工骨植入量比较差异无统计学意义(P0.05)。但观察组的骨厚度明显大于对照组(P0.05),植入腔感染率明显低于对照组(P0.05)。结论:在开窗人工骨植入术的基础上使用口腔修复膜不仅能引导骨组织再生,而且能够显著降低植入腔的感染率。

Preventive Effect of Artificial Bone Surface Covering Oral Repair Film on the Cavity Infection in Patients with Mandibular Cystic Defect Undergoing Artificial Bone Implantation

ABSTRACT Objective: To investigate the preventive effect of artificial bone surface covering oral repair film on the infection of implant in patients with mandibular cystic defect undergoing artificial bone implantation. Methods: 78 cases of patients with cystic defect of jaw in our hospital from April 2012 to February 2016 were divided into the control group (38 cases( and the observation group (40 cases) according to the time of treatment, all the patients were treated with fenestration and artificial bone implantation. The control group was treated with conventional anti infection, and the observation group was treated with artificial bone surface covering the oral repair membrane. The volume, area reduction rate, artificial bone implantation volume, bone thickness and infection rate of the implanted cavity were compared between the two groups. Results: No significant difference was found in the volume, area reduction rate and amount of artificial bone between two groups (P>0.05), but the bone thickness of observation group was significantly higher than that of the control group (P<0.05), the infection rate of implanted cavity of observation group was significantly lower than that of the control group (P<0.05). Conclusion: Fenestration artificial bone implantation is an effective method for the treatment of jaw cystic defect. On the basis of this, using oral repair membrane can not only guide bone regeneration, but also significantly reduce the infection rate of the implanted cavity.
