[Functional dynamic bridging plate and its use in the mandible]

Area of Science:

• Oral and Maxillofacial Surgery
• Biomaterials Engineering
• Orthognathic Surgery

Background:

• Mandibular defects often require complex reconstruction following tumor resection, trauma, or inflammation.
• Traditional reconstruction methods may face challenges with stability, bone remodeling, and surgical complexity.

Observation:

• The functionally dynamic bridging plate system utilizes a double bridge principle for mandibular reconstruction.
• A primary plate provides initial stability, while bone grafts form a secondary bridge, facilitating functional stress transmission.

Findings:

• The square-sectioned plate bar allows for controlled micromovements and uniform stress distribution, preventing predetermined breaking points.
• Adequate functional stress on bone transplants is crucial for successful bone remodeling and integration.
• The system simplifies intraoral fixation and bone graft positioning, regardless of immediate reconstruction.

Implications:

• This technique offers a versatile solution for partial mandibular resections, enhancing functional recovery and aesthetic outcomes.
• The design facilitates easier surgical manipulation and potentially reduces complications associated with mandibular reconstruction.
• The system's adaptability supports various reconstruction scenarios, including those with or without immediate bone grafting.
