Using a titanium printed resected human mandibular condyle as a potential replacement model: a hypothesis

Area of Science:

• Oral and Maxillofacial Surgery
• Biomedical Engineering
• Regenerative Medicine

Background:

• Replacing the mandibular condyle is complex, especially achieving precise anatomical fit within the glenoid cavity.
• Current methods face challenges in replicating the natural condyle's form and function.
• Patients with condyle loss due to tumors, resorption, or ankylosis require effective reconstructive solutions.

Purpose of the Study:

• To present a novel, cost-effective therapeutic option for mandibular condyle replacement.
• To address the challenge of anatomical fit in condyle reconstruction, particularly in resource-limited settings.
• To utilize a patient's own resected benign condyle as a template for reconstruction.

Main Methods:

• Scanning an intact, resected mandibular condyle obtained from a benign tumor.
• Using the scanned model as a template for fabricating a custom replacement condyle.
• Applying this method for patients requiring mandibular condyle reconstruction.

Main Results:

• The proposed method offers a potentially cost-effective solution for mandibular condyle replacement.
• Utilizing a patient-specific model enhances the likelihood of achieving accurate anatomical fit within the glenoid cavity.
• This approach provides a viable option for rehabilitating patients with mandibular defects.

Conclusions:

• A novel, cost-effective technique for mandibular condyle replacement using a patient's own condyle as a scanned model is presented.
• This method shows promise for improving the anatomical accuracy and functional outcome of condyle reconstruction.
• The approach is particularly relevant for developing countries facing challenges in accessing advanced reconstructive options.
