Virtual Reality Planning for Mandible Reconstruction: A Case Report.

Area of Science:

• Oral and Maxillofacial Surgery
• Biomedical Engineering
• Virtual Reality Applications

Background:

• Free fibula flap reconstruction is the standard for implant-based rehabilitation of the mandible.
• Current virtual planning methods, while common, present a complex user experience.
• Limitations in existing virtual planning necessitate innovative solutions for improved efficiency and usability.

Purpose of the Study:

• To evaluate a novel virtual reality (VR)-based application, ImmersiveRecon, for planning free fibula flap mandibular reconstruction.
• To assess the feasibility and advantages of VR surgical planning compared to traditional methods.
• To report a case of mandibular reconstruction and dental implant placement planned using VR technology.

Main Methods:

• A 17-year-old patient with a history of ameloblastoma and failed prior reconstruction underwent VR-planned mandibular reconstruction.
• Preoperative CT scans were imported into ImmersiveRecon for surgeon-led virtual planning.
• Procedure-specific guides and splints were 3D-printed, and surgical outcomes were compared to planned models.

Main Results:

• VR planning was completed by the surgeon in 5 minutes without engineer assistance.
• The surgery proceeded without complications, yielding excellent functional and aesthetic outcomes.
• Postoperative scans showed high fidelity to the VR-planned models, meeting surgical standards.

Conclusions:

• Virtual reality surgical planning for mandibular reconstruction is feasible and effective.
• ImmersiveRecon offers advantages including enhanced visualization, a simplified interface, and reduced planning time.
• VR planning facilitates successful implant-based prosthodontic rehabilitation with high precision.
