Meeting Theme: The Future of Stem Cell Research in Clinical DentistryPoster Abstracts: P-01OBJECTIVES: The objective of this retrospective study was to compare the effect of different mandibular setback amount by vertical subsigmoid osteotomy (VSSO) on the pattern of radiographic condylar remodeling in one year time span post-surgically. Methods: 200 patients diagnosed of mandibular prognathism and underwent VSSO surgery with various setback amounts from 2007 until 2012 at the Prince Philip Dental Hospital were included in this study. Pre-surgical and 1 year post-surgical Postero-Anterior Cephalogram, Lateral Cephalograms and Cone Beam Computed Tomography (CBCT) Scans were retrieved. Tracings of plain cephalometric radiographs were performed. CBCT data sets were used to measure the linear and condylar axis angle value in multiplanar view. Finally the pre- and post-surgical 3D condyle-ramus units were superimposed using stable registration point of the condylar neck and ramal area above the lingula to assess the condylar bone remodeling by ...postprin
