Cast arch bars used in orthognathic surgery.

Area of Science:

• Maxillofacial surgery
• Biomaterials science

Background:

• Dental arch bars are crucial for stabilizing the jaw during healing after trauma or surgery.
• Traditional materials may present challenges in terms of cost, patient comfort, or mechanical properties.

Purpose of the Study:

• To evaluate the suitability of cast arch bars for maxillomandibular fixation.
• To highlight the advantages of chromecobalt alloys in dental applications.

Main Methods:

• Design and fabrication of cast arch bars using chromecobalt alloys.
• Assessment of mechanical properties, including resistance to masticatory forces.
• Evaluation of patient tolerance and comfort compared to other splinting materials.

Main Results:

• Cast arch bars demonstrate stability, thinness, and sufficient strength for mastication.
• Chromecobalt alloys provide a low-cost material solution.
• The alloys are well-tolerated by patients, offering superior comfort over acrylic resin splints.

Conclusions:

• Cast chromecobalt arch bars are an effective, well-tolerated, and cost-efficient option for maxillomandibular fixation.
• These arch bars provide a stable and comfortable alternative to acrylic splints during the healing process.
