目的:观察生物可吸收内固定材料植入人体后的反应并评价其临床效果。方法:对15例颌骨骨折病例在植入可吸收夹板与螺钉内固定后的1个月、3个月、6个月随访,观察术区反应、骨端固定、咬合关系恢复及X线表现等情况。结果:所有患者均无异常反应,骨折固位稳定、愈合良好,咬合关系正常。结论:可吸收内固定系统可满足颌面部低应力区骨折内固定的临床要求。
Objective: To observe the response of bioabsorbable internal fixation materials to human body and evaluate its clinical effect. Methods: Fifteen patients with jaw fracture were followed up for 1 month, 3 months and 6 months after implantation of absorbable splint and screws. The response of operation, the fixation of bone ends, the recovery of occlusal relationship and X-ray findings were observed And so on. Results: All patients had no abnormal reaction, the fracture retention was stable, the healing was good and the occlusion relationship was normal. Conclusion: Absorbable internal fixation system can meet the clinical requirements of maxillofacial low stress fracture fixation.
