摘　　要：目的 :观察加压固定和非加压固定下颌骨骨折的组织学愈合差异 ,对两种固定形式的临床应用作出评价。方法 :采用加压和非加压接骨板固定犬下颌骨骨折 ,对两种固定的组织学、X线特点进行观察。对 98例下颌骨骨折患者采用两种方法进行治疗 ,术后观察X线、咀嚼效率恢复和一般情况。结果 :加压接骨板固定的骨折愈合形式为一期愈合 ,而小钛板为传统的骨愈合形式 ;临床应用表明加压接骨板在骨折愈合早期有明显的优势。结论 :两种方法均是下颌骨骨折良好的固定方式 ,小钛板使用方便 ,适应证广 ,加压接骨板固定骨折愈合快 ,但操作技术要求较高。Objective: To observe effects of treatment of mandibular fractures with compression or non compression internal fixation. Methods: In the in vivo study mandibular fractures were fixed by compression internal fixation on one side and non compression on other side in 15 dogs and observed radiologically and histologically. In clinical practice 42 patients with 58 mandibular fractures were treated with compression internal fixation, and 56 patients with 78 madibular fractures were treated with non compression internal fixation. Their clinical effects were evaluated by masticatory efficiency test, radiological and clinical observation after operation. Results: Primary bone healing was found histologically in group of compression fixation and bone healing through callus in group of non compression in the dogs. In the patients treated with compression internal fixation bone fracture line disappeared 1 week earlier and masticatory efficiency was heigher than in those with non comprission fixation. Conclusion: Both methods are all effective in the treatment of mandibular fractures. The miniplate is convenient in use and the indication is wide ranging. The compression plate can speed healing of mandibular fractures, but the operation is more strict technically.
