Abstract
Purpose: To determine the efficacy and longevity of patient-specific implants (PSIs) with strut abutment design to rehabilitate bilateral maxillectomy defect.
Materials and methods: Finite Element Analysis was performed on a PSI with strut abutments to repair a patient's bilateral maxillectomy defect due to COVID associated mucormycosis.
Results: The von Mises stress recorded was maximum in the zygomaticomaxillary buttress region, and displacement values were noted to be highest in the posterior-most strut, although both parameters were within acceptable limits, which is favorable.
Conclusion: The authors draw the conclusion that a PSI with strut abutments is a workable therapeutic modality for patients with these kinds of abnormalities based on this information.
