Reconstruction of mandibular dysplasia using a statistical 3D shape model

A statistical 3D shape model of a regularly developed human mandible is presented. The shape model (often referred to as an atlas) is created from 11 tomographic data sets, representing a mean mandibular shape including all of its variations to any shape of the underlying training set. The atlas will serve as a foundation for the reconstruction of missing or malformed bony structures. First preliminary results are presented for three different cases of distinct mandibular deformities, and it is shown, that such a 3D shape model might provide a reasonable basis for the planning of a surgical reconstruction. Hence, the atlas will be extended by at least 140 available data sets that have been acquired using a NewTom DVT.
