Fabrication of orbital prosthesis by two different methods in patients with post-COVID-19 rhino-orbital maxillary mucormycosis: A case series.

Neoplasms, congenital disorders, fungal infections, and traumatic injuries are the predominant causes of orbital defects. Various retentive mechanisms such as application of adhesive, utilization of mechanical undercuts, and implant-supported attachments are generally used in the maxillofacial prosthesis. In the orbital region, the result of magnet-retained attachments is favorable compared with other mechanisms. Different advantages of the magnet-retained prosthesis are less manual dexterity needed during insertion or removal and better maintenance of hygiene. The skin-implant interface and thick tissues in the maxillofacial region are the critically important points that should be given importance during the planning and placement of implants. Ideally, implant sites for orbital prosthesis are the lateral, infra-, and supraorbital rims of the orbital region. The following case series describes two different methods to rehabilitate patients with an exenterated eye due to mucormycosis by individually designed implant with magnetic attachment and mechanical undercut-retained orbital prosthesis.
