摘　　要：目的：测定在加压钢板作用下，下颌骨骨断端间的压力。方法：选用３只狗新鲜下颌骨标本，任选一侧用钢锯将下颌骨体部锯开，加压钢板固定后用电测法测定骨断端间的最大压力。结果：钢板固定后产生的最大骨断端压力为３８ｋｇ～４１ｋｇ。结论：由于钢板固定后产生的骨间压力高于口腔功能活动所需的牙合力，加压钢板。Objective: To measure the interfragmentary compresion force produced by the use of compression plate in mandibular fracture. Methods:Three fresh mandibulae of dogs were used to make the fixation models, The mandibular bodys were fractured with osteotomy and fixed with compression plate. Stressgauge measurement technique was used to measure the compression force between the fragments.Results:With compression plate fixation, the interfragment compression force was 38 kg～41 kg. Conclusion:The interfragment compression force produced by the compressin plate is stronger than that produced by occlusal function, therefore the plate is suitable for internal fixation of mandibular fracture.
