Evaluation of two different methods of arch bar application: a comparative prospective study

Area of Science:

• Oral and Maxillofacial Surgery
• Surgical Instrumentation
• Dental Procedures

Background:

• Arch bars are crucial for managing maxillofacial trauma and dental alignment.
• Traditional wire twisters pose risks of sharps injuries to operators.
• Evaluating novel instruments can improve procedural safety and efficiency.

Purpose of the Study:

• To compare the efficacy of a pencil-type wire twister versus a normal wire twister during arch bar application.
• To assess parameters including operator safety, procedure duration, and patient comfort.

Main Methods:

• A randomized study involving 120 patients requiring arch bar application.
• Two groups were formed: Group A (pencil-type twister) and Group B (normal twister).
• Patient and operator outcomes were assessed using questionnaires and statistical analysis (paired samples t-test).

Main Results:

• The pencil-type twister group (A) showed significantly fewer glove perforations and wire stick injuries compared to the normal twister group (B).
• Procedure time and wire breakage were reduced with the pencil-type twister.
• Operators reported greater ease, and patients experienced higher comfort levels with the pencil-type twister.

Conclusions:

• The pencil-type wire twister offers superior efficacy and safety in arch bar application.
• Its use enhances operator performance and patient experience, making it a preferred alternative.
