Mandibular reconstruction using a special plate. Animal experiments and clinical application

Area of Science:

• Oral and Maxillofacial Surgery
• Biomedical Engineering
• Reconstructive Surgery

Background:

• Current mandibular reconstruction methods lack satisfactory restoration of functional stability, joint function, and masticatory function.
• Varied clinical challenges necessitate innovative solutions for mandibular defects.

Observation:

• Development of a novel reconstruction plate with U-shaped notches for universal adaptation.
• Inclusion of a condylar prosthesis and a reconstruction plate with a condylar head in the design.
• Animal experiments demonstrated the achievement of stability under functional stress.

Findings:

• The novel reconstruction plate enabled universal adaptation and provided stability under functional stress.
• Intermaxillary fixation was rendered unnecessary due to the achieved stability.
• Clinical application showed a reduction in masticatory disability, correlating with experimental results.

Implications:

• The developed reconstruction plate and prosthesis offer a promising solution for mandibular defects.
• The experimental model validates the effectiveness of the new approach in restoring mandibular function.
• This advancement may lead to improved patient outcomes in reconstructive surgery.
