How to produce pre-shaped rigid arch bars using low-cost 3D printing technology - A technical note

Area of Science:

• Oral and Maxillofacial Surgery
• Biomedical Engineering
• 3D Printing Technology

Background:

• Mandibulo-maxillary fixation is crucial for many oral and maxillofacial procedures.
• Traditional arch bars are commonly used but have limitations in severe trauma or malformations.
• Conditions like temporomandibular joint ankylosis can preclude the use of rigid arch bars.

Purpose of the Study:

• To report the development of a novel technique for creating pre-shaped rigid arch bars using 3D printing.
• To present a case study involving complex craniofacial fractures treated with 3D-printed arch bars.
• To outline the indications and limitations of this 3D printing-based approach.

Main Methods:

• Utilizing 3D printing technology to fabricate custom, pre-shaped rigid arch bars.
• Applying the technique to a patient with Le Fort 1, 2, and 3 fractures, palatine disjunction, mandibular fracture, and zygomatic fractures.
• Detailed documentation of the fabrication process and clinical application.

Main Results:

• Successful fabrication of pre-shaped rigid arch bars tailored to complex anatomy.
• Demonstration of the technique's applicability in a severe craniofacial trauma case.
• Identification of specific scenarios where this method is advantageous.

Conclusions:

• 3D printing offers a viable method for producing patient-specific, rigid arch bars.
• This technique overcomes limitations of conventional arch bars in complex oral and maxillofacial cases.
• Further evaluation of indications and limitations is recommended for broader clinical adoption.
