摘要目的 探讨张闭几练习及咬合训练在少年髁状突骨折后自然改建改中的作用.方法 选择少年髁状突骨折患者46例及同龄健康少年46名,髁状突骨折患者手术后4周开始进行张闭口练习及咬合训练,一年后根据颞颌关节中位断层片的情况,对颞颌关节进行绘画测量分析.结果 有4例患者在张闭口练习及咬合训练初期出现颞颌关节病症状,9例髁状突骨折后的小骨片在改建过程中部分被吸收.治疗一年后髁状突骨折患者关节前间隙为(2.88 ±0.76)mm、关节后间隙为(2.35 ±1.03)mm,髁突位置基本居中(N/M 1.09 ±0.23),与同龄健康少年的颞颌关节无明显差异.结论 在少年髁状突骨折后自然改建改的过程中,张闭几练习及咬合训练具有重要的价值.

abstractsObjective To discuss the action which opening the mouth practice and occlusal training was in the juvenile occlusion condylar fracture after the natural reconstruction.Methods Selected 46 patients of juvenile condylar fracture and 46 the same age of healthy adolescents.Condylar fracture patients after surgery for four weeks began to open the mouth exercise and occlusal training,after one year,according to the case of Temporomandibular joints middle position layer film,They could do measurement and analysis of painting to temporomandibular joint.Results Four patients had TMJ dysfunction history syndrome in opening the mouth and the beginning of occlusal training.Nine cases condylar fracture of the small bone in converted part of the process of being absorbed.One year after treatment condylar fractures in patients with pre-clearance for the joint(2.88±0.76) mm,Joint posterior space was ( 2.35 ±1.03 )mm,Condylar basic middle position (N/M 1.09±0.23),The same age,health and juvenile TMJ no significant difference.Conclusion In the juvenile condylar fracture to the natural process of conversion,opening the mouth exercise and occlusal training is of important value.
