Rhinocerebral mucormycosis was the most common form, often requiring extensive surgical debridement resulting in complex maxillary defects. These defects pose significant challenges for rehabilitation, affecting mastication, speech, aesthetics, and overall quality of life.Conventional removable prostheses often fall short due to poor retention and stability in such cases. Zygomatic and pterygoid implants have emerged as viable alternatives, offering improved support and functional outcomes in patients with limited maxillary bone. However, literature detailing their use in post-mucormycosis cases remains scarce.

This report presents the case of a 48-year-old male who developed post-COVID mucormycosis, leading to a left total and right partial maxillectomy. Following soft tissue closure using regional flaps, the patient underwent implant-based rehabilitation using four zygomatic implants, one pterygoid implant, and one anterior tilted implant. Implant placement was guided by CBCT, virtual planning, and stereolithographic modeling. A screw-retained, titanium bar-supported prosthesis with a PMMA superstructure was delivered on the second postoperative day, restoring function and aesthetics.

The use of zygomatic and pterygoid implants in this case provided a stable, predictable foundation for prosthetic rehabilitation, eliminating the need for extensive bone grafting or patient-specific implants. With proper planning and execution, these implants offer an effective solution for complex post-maxillectomy defects, especially in cases following mucormycosis.
