  • 3-Dimensional Dental Scanner: Assuring Healthy Smiles

    2001-8-1 · The 3-dimensional arrangement of teeth in a normal, healthy human dentition follows some general rules. For instance, the occlusal surfaces of teeth in the mandibular arch have been described as tangent to a 100-mm (or 4-inch) sphere, which was first described by Monson about 80 years ago.1 This global spatial disposition, which also has recently been measured in different age groups,2,3 ...

    Seventy-nine Japanese adults (42 males and 37 females, aged 18 to 37 years) with intact dental arches were recruited, and the occlusal curvature was estimated by calculating the radius and center position of the approximate sphere. Besides, the relative contribution of gender, age, dental arch length and width, overjet, overbite for the radii ...

    Unfortunately, reconstructed knee joints often exhibit different mechanical behaviours to healthy joints; for example, in a recent study, 22 out of 26 ACL-reconstruction patients experienced differences in tibial rotation between their ACL-reconstructed and contralateral knees (Scanlan et al., 2010). One potential cause of these differences in mechanical performance could be the microstructural differences …
