简单有效的骨折固定,是治疗下颌骨骨折的最佳选择,我科采用自凝塑料牙弓斜面导板单颌固定方法(Arch bar guiding incline with coldcuringresina in fixated mandibular fracture简称ABGl)治疗31例下颌骨骨折病人,取得良好效果,现介绍如下。 1 临床资料 1.1 一般情况 男25例,女6例;年龄16～63岁,平均38岁。单发性骨折24例,粉碎性骨折7例,合计骨折部位共37处。其中下颌角骨折6处,颏孔区骨折22处,颏正中骨折9处。 1.2 治疗方法 移位骨折片手法复位,恢复正常咬合关系,单颌牙弓夹板结扎固定,在上下颌正中咬合位时,于下颌唇弓夹板牙面敷自凝塑料至上前牙唇侧的切1/3和上颌后牙颊尖斜面,形成附着于牙弓夹板上斜面导板,硬固后调磨、抛光使之不压迫牙
Simple and effective fracture fixation is the best choice for the treatment of mandibular fractures. Our department used Arch bar guiding incline with cold curing intradental in fixated mandibular fracture (ABGl) for 31 cases of mandibular fractures Patients, achieved good results, are presented below. 1 Clinical data 1.1 General Male 25 cases, 6 females; aged 16 to 63 years, mean 38 years. 24 cases of single fracture, comminuted fracture in 7 cases, a total of 37 fracture sites. Including 6 cases of mandibular fractures, mental fossa fracture 22, median mental fracture 9. 1.2 Treatment of displaced fracture plate reset, to restore the normal occlusion relationship, a single maxillary arch splint ligation in the middle of the mandibular occlusal position, the mandibular lip arch splint self-adhesive plastic material to the upper lip side of the cut 1 / 3 and maxillary posterior teeth buccal sharp bevel, the formation of attached to the arch on the dental arch ramp guide, hardened after grinding, polishing so that it does not pressure teeth
