Assessment of Accuracy and Orbital Volume Using Patient Specific Titanium Implant Vs Patient Specific Zirconia Implant for Orbital Floor Reconstruction in Blowout Fractures A Randomized Clinical Trial: Comparative Study

Patients of both groups will be subjected to:

1. Case history including personal data, medical, surgical history and family history.
2. A full examination of the cranial and maxillofacial skeleton and soft tissue .
3. Evaluation of Visual Functions
4. Ophthalmologic consultation and clearance
5. Radiographic examination: CT scan
6. All DICOM data will be imported to the surgical planning software.

Virtual planning:

1. A midsagittal plane will be constructed then the normal orbit will be mirrored to the affected side.
2. The mirrored orbital floor will be meshed with 1.6 mm holes then its peripheries will be extended downwards by 3 mm and meshed also in order to accommodate the fixation.
3. The designed part will be subtracted then exported in Stereolithography (STL) format to be fabricated .

The surgery will be done under General anesthesia and undertaken within 14 days to prevent fibrosis. Can be delayed 24-72 hours to allow the edema to subside before undertaking surgery.
