A method for constructing teeth and maxillary bone parametric model from clinical CT scans

The use of precise geometric models can be of great importance to grant the validity of a computer simulation. Advanced reconstructive techniques must be used to ensure that goal. The authors describe a method to digitally reconstruct a complete model of a toothed maxilla using conventional computerized tomography and manual manipulations based on literature references to correct inaccuracies in the model. The result is a geometric model that can be edited or used as-is in a wide range of research areas such as orthodontics, prosthetic dentistry and restorative dentistry. The model can be downloaded and used freely by the scientific community.
