MethodsThree-dimensionalreconstructionwasperformedbyMimicssoftwarebasedonthepreoperativeCTdata.Themodel ofthemaxillofacialregionwasimported intoRapidformsoftware for measuring the associated parametersand Geomagic softwareforsimulationofosteotomy. Thereliabilityofthevirtualoperationwasvalidatedduringthesurgery. ResultsThe modelofmandibularretrusionwasreconstructedandsuccessfullyusedtosimulatethesurgery.
