Summary

This study showcases the successful use of three-dimensional (3D) techniques to create a titanium patient-specific implant (PSI) for reconstructing a severe maxillofacial defect caused by mucormycosis. The PSI improved facial symmetry, function, and well-being, demonstrating advanced digital dentistry solutions.

Area of Science:

Maxillofacial surgery
Biomaterials engineering
Digital dentistry

Background:

Mucormycosis infections can lead to extensive maxillofacial defects, causing significant functional and aesthetic challenges.
Reconstruction of subtotal maxillectomy defects, such as Aramany class 1 and Cordeiro type II, presents complex surgical issues.
Traditional reconstruction methods may not fully address occlusal function, facial asymmetry, and patient psychological well-being.

Observation:

A patient with a post-COVID mucormycosis infection required hemimaxillectomy, resulting in a significant maxillofacial defect.
The patient underwent reconstruction using a custom-designed titanium patient-specific implant (PSI).
Three-dimensional (3D) imaging and computer-aided design/computer-aided manufacturing (CAD-CAM) technologies were integral to the implant's fabrication.

Findings:

The patient-specific implant successfully restored facial symmetry and improved occlusal function.
Immediate dental rehabilitation was achieved, significantly enhancing the patient's quality of life and psychological state.
The PSI approach demonstrated superior outcomes compared to conventional reconstruction methods.

Implications:

Patient-specific implants engineered with 3D techniques offer a viable and effective solution for complex maxillofacial defects.
The integration of CAD-CAM technology in maxillofacial reconstruction represents a significant advancement in personalized medicine.
This case highlights the potential of digital dentistry to improve functional and aesthetic outcomes in patients with post-infectious defects.
