Application of Erich arch bar with the help of circumdental wires for intermaxillary fixation is most widely accepted method for mandibular fractures. However, circumdental wires causes injury to periodontium. There is always fear of inadvertent injury by wire ends and chances of serotransmission of blood born viruses to the operator thus, we want to use the safest method of intermaxillary fixation avoiding use of circumdental wires.
We modified arch bar and bonded it to the dental arches by light cure composite resin and intermaxillary fixation was done without circumdental wires. Comparative study against conventional Erich arch bar fixation and evaluation concerning the oral hygiene, stability and safety of operator was made among 20 patients in two groups.
As per our observation and result, resin bonded arch bar is easy to apply, causes less periodontal injury, and its application minimizes threat of percutaneous injury to operator.
借助环绕牙弓丝应用 Erich 牙弓夹板进行颌间固定是下颌骨折最广泛接受的方法。然而,环绕牙弓丝会对牙周组织造成损伤。总是存在钢丝末端意外损伤的风险以及血源性病毒向操作者血清传播的可能性,因此,我们希望使用最安全的颌间固定方法,避免使用环绕牙弓丝。
我们对牙弓夹板进行了改良,并用光固化复合树脂将其粘结到牙弓上,在不使用环绕牙弓丝的情况下进行颌间固定。在两组的 20 名患者中,针对传统 Erich 牙弓夹板固定进行了对比研究,并对口腔卫生、稳定性和操作者安全性进行了评估。
根据我们的观察和结果,树脂粘结牙弓夹板易于应用,对牙周组织损伤较小,其应用将操作者经皮损伤的威胁降至最低。
