Viewbox tutorials

Measure tooth movement (PDF file)

Measure individual tooth movement from initial to final position on 3D digital casts. To practice this tutorial you need to additionally download the following files into your Viewbox folder (usually: My Documents/dHAL Viewbox 4/):
Maxillary cast, initial (OBJ format)
Maxillary cast, final (OBJ format)

Digitize 3D mandible (PDF file)

Digitize a mandible using the Mandible3D template. This template contains curves, curve semi-landmarks and surface semilandmarks that cover the whole mandibular surface. To practice this tutorial you need to additionally download the following files into the Templates folder of your Viewbox folder (usually: My Documents/dHAL Viewbox 4/Templates):

Compute distance colour map (PDF file)

Compute the distance colour map between two aligned meshes. To practice this tutorial you need to additionally download the following files into your Viewbox folder (usually: My Documents/dHAL Viewbox 4/):
Maxillary cast, initial (OBJ format)
Maxillary cast, final (OBJ format)

Create a Template (PDF file)

Create a basic Template in Viewbox. The Template allows for digitising a few landmarks on a cephalometric radiograph and measures the angle between the upper incisor and the palatal plane.

Structural Superimposition [YouTube]

This tutorial shows you how to do structural superimposition of cephalometric radiographs using the Viewbox software. The images of the radiographs are coloured and blended together, making it easy to tell them apart and move them to the correct position.

Create a Template for 3D facial scans [YouTube]

This tutorial shows you how to create a template for digitizing facial scans. The template includes fixed points on anatomical landmarks of the face, and 400 semilandmarks on the facial surface. These semilandmarks will be considered sliding semilandmarks and could be adjusted by minimizing the bending energy (or Procrustes distance) relative to a reference configuration. The tutorial shows how to distribute the points uniformly over the facial surface and prepare them for sliding. The tutorial assumes Viewbox version 4.0.1.4 or later.

Digitize a 3D Facial Scan [YouTube]

This tutorial shows you how to digitize a 3D facial scan. The Template contains 400 semilandmarks that are automatically positioned using a Thin Plate Spline deformation between the patient and the Template, based on the fixed points. Then, the semilandmarks are projected and slid on the surface in an iterative fashion, until bending energy between the two configurations is minimized. The tutorial assumes Viewbox version 4.0.1.4 or later.
