Robot-Assisted Zygomatic Implant Placement for Hemimaxillectomy Defect Reconstruction: A Case Series
Summary
Robotic surgery enables precise placement of zygomatic implants (ZIs) for maxillary reconstruction after hemimaxillectomy. This innovative approach improves patient outcomes and oral health, offering a viable treatment option.
Area of Science:
- Oral and Maxillofacial Surgery
- Medical Robotics
- Biomedical Engineering
Background:
- Zygomatic implant (ZI) placement for maxillary reconstruction faces challenges due to complex anatomy and limited surgical access.
- Robotic technology offers potential for enhanced accuracy in complex surgical procedures.
Purpose of the Study:
- To present a clinical digital workflow for robotic-assisted zygomatic implant placement and immediate restoration in hemimaxillectomy defects.
- To evaluate the feasibility, accuracy, and clinical outcomes of this robotic approach.
Main Methods:
- A digital workflow involving CBCT, intraoral scanning, virtual planning, and robotic-assisted surgery was employed.
- Eight zygomatic implants were placed in four patients with maxillary defects.
- Immediate prosthetic restoration followed implant placement.
Main Results:
- Successful robotic placement of eight zygomatic implants with minimal deviations (entry: 1.97±1.15 mm, exit: 1.79±1.04 mm, angular: 1.92±0.76°).
- No biological or mechanical complications were noted during 2-15 months follow-up.
- Significant improvement in Oral Health Impact Profile-14 scores was observed postoperatively.
Conclusions:
- Robotic-assisted zygomatic implant placement is a feasible and effective technique for reconstructing maxillary defects.
- This approach offers a promising clinical solution for patients with hemimaxillectomy defects, improving functional and aesthetic outcomes.
