[The use of patientspecific implants in maxillofacial reconstruction]

The reconstruction of facial skull defects remains a challenging task in our days. In addition to its complex anatomy and multiple complex functions, this area is also of aesthetic importance. In all cases, reconstruction must aim to achieve anatomical or functionally equivalent reconstruction and to restore facial harmony. The advent of modern imaging tools, design software and 3D printers has led to the replacement of traditional titanium miniplates and screws used in maxillofacial traumatology by custom prostheses designed digitally, and manufactured using additive manufacturing technology to suit the patient’s individual circumstances. We carried out a total of 11 cases of facial skull and frontal bone reconstruction using patient-specific implants between 2010 and 2022. The design process and the potential for clinical application are presented through two case studies of our own. In all cases, the implants healed without complications, and no wound healing complication or rejection was observed. The reconstruction was aligned with the virtual plan, resulting in a significant aesthetic improvement. Our experiences to date indicate that patient-specific implants represent a reliable option for the reconstruction of maxillofacial defects. Orv Hetil. 2024; 165(40): 1594–1600.
