This investigation was carried out to compare Dimac wires with arch bars for interdental immobilization.
The assessment was conducted on 50 patients who had mandibular fractures and in whom intermaxillary fixation was required as a part of the treatment. The time required for applying each method of fixation, the needle-stick injuries that occurred during their application, and the periodontal damage that followed interdental immobilization was investigated.
The mean time required for the application of Dimac wires was significantly less than that required for arch bars. The needle-stick injuries were significantly less with Dimac wires. Patients reported difficulty with oral hygiene with arch bars in place. This was associated with periodontal damage following removal of fixation.
Dimac wires is safer to use and less traumatic to the periodontium
本研究旨在比较迪马克丝（Dimac）丝与牙弓夹板用于牙间固定的效果。
对50例下颌骨骨折且治疗中需要颌间固定的患者进行评估。研究了应用每种固定方法所需的时间、应用过程中发生的针刺伤以及牙间固定后随之出现的牙周损伤情况。
应用迪马克丝丝所需的平均时间明显少于牙弓夹板。迪马克丝丝导致的针刺伤明显更少。患者报告佩戴牙弓夹板时口腔卫生维护困难。这与去除固定后出现的牙周损伤有关。
迪马克丝丝使用更安全，对牙周组织的创伤更小
