1·Objective: To investigate the effect of open-mouth jaw plate in the treatment of condylar fracture in children.
目的：探索开口牙合板在儿童髁状突骨折保守治疗中的价值。
2·Jaw crusher wit optimized crushing chamber has high output, high crushing ratio and low steel consumption for jaw plate.
优化破碎腔的颚式破碎机可提高破碎机的产量、破碎比且可降低颚板钢耗。
3·But the jaw plate must be replaced frequently because the abrasion is severe for intense impact and attrition wear from ores.
但是，由于颚式破碎机工作时受到矿石的强烈撞击和磨损，磨损仍然非常严重，几天就需要更换新的颚板。
4·Main products are: Continental C Series jaw crusher machine and its components, a moving jaw, front plate, back plate, dental plates, side guard, jaw plate, eccentric shaft, flywheel, bearing, etc.
主营产品有：欧式C系列颚式破碎机整机及其部件，有动颚、前板、后板、牙板、边护板、颚板、偏心轴、 飞轮、 轴承座等；
5·The angle between toggle plate and moving jaw increases when moving jaw moves up.
之间的夹角肘板和动颚上升时下颚向上移动。
6·Broken such materials, plate hammer or hammerheads for high manganese steel can, so have the equipment jaw crusher, like bluestone, limestone hardness small and crisp.
破碎这样的物料，板锤或是锤头为高锰钢即可，这样的设备有颚式破碎机，而像青石、石灰石硬度小且脆。
7·Results All the patients had normal jaw morphology, and occlusion relation were restored after operation, and the itanium plate without any rejection reaction, no loosening or displacement.
结果21例陈旧性颌骨骨折患者术后咬关系恢复，张闭口正常，颌骨形态良好，钛板无松动、移位和排异反应。
8·Objective To investigate the causes of plate removal after plate rigid internal fixation for jaw fractures.
目的探讨颌骨骨折坚强内固定术后取钛板的原因。
9·Conclusion Small plate with rigid internal fixation between the fixed jaw jaw fracture treatment under the effect of reliable, less post-operative complications, is an ideal method of operation.
结论小型接骨板坚固内固定辅以颌间固定治疗下颌骨骨折效果可靠，术后并发症少，是一种理想的手术方法。
10·Conclusion: the inter maxillary traction screw with titanium plate osteosynthesis is an effective way in the treatment of jaw fracture.
结论：利用颌间牵引钉联合钛板坚固内固定治疗颌骨骨折是一种较好的方法。
