Author – Majumdar S Methods for measuring the structure of craniofacial bones are discussed in this paper. In addition to the three‐dimensional macro‐structure of the craniofacial skeleton, there is considerable interest in imaging the bone at a microscopic resolution in order to depict the micro‐architecture of the trabecular bone itself. In addition to the density of the bone, the micro‐ architecture reflects bone quality. An understanding of bone quality and density changes has implications for a number of craniofacial pathologies, as well as for implant design and understanding the biomechanical function and loading of the jaw. Trabecular bone micro‐architecture has been recently imaged using imaging methods such as micro‐computed tomography, magnetic resonance imaging, and the images have been used in finite element models to assess bone mechanical properties. In this paper, some of the recent advances in micro‐computed tomography and magnetic resonance imaging are reviewed, and their potential for imaging the trabecular bone in mandibular bones is presented. Examples of in vitro and in vivo images are presented.
