Purpose:
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.
Methods And Result:
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.
Conclusion:
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.
