TITANIUM MESH COATED WITH NATURAL HYDROXYAPATITE NANOCRYSTALS IN ORBITAL RECONSTRUCTION (RANDOMIZED CONTROLLED CLINICAL TRIAL)

BACKGROUND: One of the most frequent facial fractures is an orbital fracture, and multiple wall restoration is frequently required following high-energy trauma. Correct planning, thorough surgical dissection, and appropriate selection of the kind, size, and shape of the reconstruction material are all necessary for a successful outcome. The appropriate material to use to restore the orbital floor and walls is still up for debate. For that aim, numerous materials have been described from various sources. The ultimate goals involve treating the bony orbital deficiency while restoring anatomy, volume, function, and esthetics. While each type of material has benefits and drawbacks, the ability to fulfill those. AIM OF THE STUDY: This study evaluated the difference in the bone density after orbital floor fracture reconstruction with titanium mesh coated with natural nanohydroxyapatite by electrophoretic deposition versus conventional titanium mesh. PATIENTS & METHODS: This study was carried out clinically on 12 adult patients with fractures of the orbital floor that should be treated with internal fixation and open reduction. The patients were divided into 2 groups, (group A): patients where the reconstruction was done using coated titanium mesh with hydroxyapatite nanocrystals and (group B): the repair and reconstruction of the defect was using conventional titanium mesh. RESULTS: The radiographic differences in bone density between the study and control groups were statistically significant. CONCLUSION: The ongoing study displayed better bone density outcomes in reconstructed orbital floor defects with coated titanium mesh when compared to uncoated titanium mesh.
