Zygomatic Fractures Clinical Trial
— CAD-CAMOfficial title:
Comparison of Two Different Modalities for Orbital Reconstruction Based on CAD-CAM Technology: A Clinical Randomized Trial
Reconstruction of orbital defects resulting after trauma; tumor resection; maxillary cyst; craniofacial anomalies and sequestrated bone…. etc., has been a challenging issue over the years and this owing to the complicated anatomy of orbit. Inaccurate orbital reconstruction may lead to devastating cosmetic and functional complications. Titanium mesh for orbital reconstruction has now become "probably" the most popular material for orbital wall reconstruction worldwide. Innovation of CAD-CAM technology and its application in maxillofacial surgery will markedly improve the surgical outcome. This study will assess the accuracy of orbital reconstruction using CAD-CAM technology and to compare two different modalities for orbital reconstruction based on this technology.
