AS17B43B - Thomas M. Graber Award of Special Merit Lecture: Accuracy of Cone Beam Computed Tomography in Assessing the Internal Trabecular Structure of the Mandibular Condyle

Apr 24, 2017 1:45pm ‐ Apr 24, 2017 2:05pm


Although CBCT has been widely used to investigate the cortical structure of various anatomical structures in the maxillofacial region, the use of CBCT to image trabecular bone in the past has been very limited. With recent advances in imaging technology, imaging of the trabecular component of bone is now possible. This presentation will answer the questions: Can CBCT imaging accurately assess trabecular bone of the mandibular condyle as compared to high resolution micro-CT? What trabecular bone properties can be accurately assessed using CBCT and do they have potential to aid in the early diagnosis of TMJ osteoarthritis?

Learning Objectives:

  • Demonstrate that CBCT can image various trabecular bone parameters as compared to micro-CT.
  • Identify various parameters that can be accurately assessed using CBCT and which of these may be used as potential radiographic biomarkers for TMJ osteoarthritis.
  • Comprehend the limitation of using CBCT to image trabecular bone.
