Summary

Two orbital prosthesis were made to the patient , using two different digital scanning methods to restore the unilateral orbital exentration , the prosthetic devices were made using medical silicon material

Detailed description

Statement of problem : Orbital defects which resulted from surgical removal of mucormycosis that caused by corona virus infection lead to several functional, esthetic and psychological problems for the patients. Aim of the study : Evaluation of the accuracy of fitting surface of orbital prosthesis constructed by photogrammetry scan. Methods : An orbital prosthesis was made using photogrammetry scanning technique as a method for making digital facial impression to obtain facial 3D model using a high resolution professional camera with image processed through 3DF Zephyr open-source software and the other orbital prosthesis was made using a conventional impression for both the defect and contralateral healthy eye , then scanned with a Degree Of Freedom (DOF) extra oral desktop scanner. 3D models of the defect sites were printed from each scanning method to act as a master cast for the orbital prosthesis fabrication. Accuracy of orbital prosthesis fitting surfaces produced from the two techniques in comparison with a facial scan as a reference scan was assessed through deviation analysis using metrology grade software (Geomagic Control X ).
