Abstract

Abstract: The objective of this study is to determine the value of using 3D planning tools and 3D printed cutting guides in Le Fort III osteotomies with external frame distraction osteogenesis. The process of planning and transfer of the virtual planning to the operating room is illustrated with 5 case. The virtual planning is transferred to the operating room using a 3D-printed supra-orbital reference bar with puzzle connections for the planned osteotomy guides. Different systems are presented to transfer the vector of distraction and the position of the external midface distractor. Three-dimensional planning tools and cutting guides help to design the Le Fort III osteotomy and the distraction vector, to anticipate possible difficulties, and to avoid adverse events.
