Ricostruzione virtuale 3D di una clavicola frammentata

The work presents a methodology for the virtual reconstruction of broken human bones coming from archaeological contexts and useful even for surgical purposes. The case report involves the reconstruction of a left incomplete clavicle considering the opposite right one. The methodology consists of virtual acquisition of the two-pieces broken left clavicle and of the right integer one by means of a 3D laser scanner, using the 3D mirrored model of the last one as reference model to reconstruct the left clavicle. Three grids characterized by an increasing number of homologous landmarks are identified on both the 3D meshes and are used to perform the warping process. The three digital reconstructed models provide a reliable correspondence with the left clavicle original one, highlighting indeed that an increased number of landmarks do not improve the final result.
