Abstract

Introduction

Complications in patients post-COVID 19 viral infection are many and include maxillary mucormycosis. Mucormycosis is usually treated with radical maxillary resection and debridement of involved structures along with the use of anti-fungal agents. The extensive removal of hard and soft tissue results in severe functional and cosmetic defects. Rehabilitation of these patients requires implant-supported prosthesis for adequate retention. However, the lack of adequate bone in the maxilla precludes the use of conventional dental implants alone for dental rehabilitation and often requires additional zygomatic implants. These implants can usually support a removable over denture prosthesis.

Case Reports

This article describes two cases, wherein patients had had an extensive resection and their removable obturator prosthesis were not retentive enough. These patients were successfully rehabilitated using zygomatic implants supported removable prosthesis. Both the patients were satisfied with the cosmetic and functional rehabilitation. At the end of one year follow up, the implants and prosthesis were stable.

Conclusion

Zygomatic implants are a useful tool to rehabilitate patients who have undergone maxillary resection for management of post-COVID maxillary mucormycosis defect (PCMMD).
