ABSTRACT

Objectives: The Purpose Of This Study Was To Evaluate The Clinical And Radiographic Outcomes Of Patient Specific CAD/CAM Condylar Plate After Unilateral Subcondylar Fracture Reduction And Fixation.

Materials and Methods: This Study Was Conducted On Six Cases Of (four With Unilateral Subcondylar Fractures And Two With Bilateral Subcondylar Fractures) Indicated For Open Reduction And Internal Fixation, The Methods Were Developed With 3D Slicer 4.8 Software And The Capabilities Of 3D Slicer Software Were Extended By TCL Scripting Plugins And Combined With ITK-SNAP Software, Modeling Of The Patient Specific Condylar Plate Was Performed With Geomagic FreeForm Plus Software For 3D Organic Modeling On The Reduced Fracture Fragments. Each Titanium Plate Was Manufactured Via Direct Metal Laser Sintering (DMLS), For Measuring Accuracy Of Postoperative 3D Virtual Reduction. Result: The Average Mean Distance Error Between Superimposed Surfaces Calculated From All Six Cases Was 0.35 Mm (SD = 0.083 Mm) Conclusion: The Patient Specific Condylar Plate Provided Very Accurate 3D Reduction Of Both Segments Especially In The Medio-lateral Direction As Proved By Our Results Which Is Considered The Most Important Advantage Gained Throughout Our Research Study.
