Symmetry considerations for volumetric implant-planning.
Symmetry Considerations can be used not only to plan the desired shape of reconstructured bone structures, but also to generate prototypes for soft tissue implants. The paper describes a system which allows to calculate a symmetry plane in the facial area automatically and computes proposals for implants or transplants. This is done by using a Simulated Annealing algorithm to determine the best reflection and morphologig operators to calculate the implant. The system presented has been used to calculate soft tissue implants in the facial area and a replacement for parts of the lower jaw.
