3D Scanning, Imaging, and Printing in Orthodontics

Urban 3d Modelling Using Terrestrial Laser Scanners

This paper describes a technique for 3D Reconstruction of large outdoor areas using terrestrial laser scanning. It presents the paradigm for automated 3D registration and requirements of the positioning and orientation subsystem to handle fully automatic 3D registrations. It analyzes the different problems and difficulties associated with such type of environments, including the analysis of sca...

3D Orthodontics - from Verne to Shaw

As children receiving new toys, we are approaching a great new world of fantasy. Three-dimensional image devices arrived at the port of Orthodontics with increasingly strong anchors firmly holding to the ground. In this case, immobility is symbolical and inversely proportional to the ongoing possibilities we are not even capable to imagine. Perhaps, the French novelist Julio Verner could. Where...

Restitution of Sculptural Groups Using 3D Scanners

Imagine for a moment that you have to solve a 3D jigsaw of which you have lost several pieces. You have also lost the original box-top showing the final picture, and as if that were not enough, some of the pieces you do have may belong to some other jigsaw. This is in essence the sort of challenge that we faced in the novel project that we shall be describing in this paper. The final aim of the...

Measuring 3D shape in orthodontics through geometric morphometrics

BACKGROUND Geometric morphometrics (GMM) has been traditionally applied to the field of biology to study developmental differentiations between species. Orthodontics deals with the shape and size of the face and its components. While several tools have been used to measure size, proportions, and relations between anatomical components, shape has been mainly described by esthetic criteria. The p...
