摘要
目的:评价颌间结扎钉进行颌间牵引固定的疗效。方法:对63例下颌骨骨折切开复位内固定的患者随机采用牙弓夹板或颌间结扎钉进行颌间牵引固定,比较操作时间、治疗后牙周指数、张口度、咬合关系及骨折愈合情况。结果:采用颌间结扎钉治疗的患者咬合关系、骨折愈合及张口度与采用牙弓夹板的患者无明显差别,其操作时间较采用牙弓夹板明显缩短,牙周健康指数明显好于采用牙弓夹板的患者。结论:颌间结扎钉操作简单省时、易于保持口腔清洁,是较理想的颌间牵引固定新方法。
Objective: To evaluate fixation effect of intermaxillary fixation screw. Methods: 63 cases with mandibular fractures were treated with open reduction, and then internal fixation were managed with intermaxillary fixation using dental arch splint or intermaxillary fixation screw randomly. The operation time, postoperation periodontal index, mouth open degree, occluding relation and fracture healing were compared. Results:There was no significant difference upon occluding relation, fracture healing and mouth open degree under two treatment methods. Compared with dental arch splint fixation method, intermaxillary fixation screw had shorter operation time and better periodontal index. Conclusion:Intermaxillary fixation screw is a good intermaxillary fixation method because of short operation time. Furthermore, it can provide enough traction retention strength and easy to maintain oral hygiene.
