Abstract
Virtual planning is increasingly used in orthognathic surgery and offers a number of advantages over conventional techniques. One of the difficulties however is reproducing these planned movements in accurately executed surgery. A number of techniques have previously been proposed in the literature to remove the reliance on occlusal wafers when positioning osteotomised bone segments, these include the use of tooth or tissue born cutting and or positioning guides. We describe the use of patient specific tissue born cutting guides and osteosynthesis plates in a segmental maxillary osteotomy and genioplasty. Planning was performed using the Materialise Proplan software communicated through a web meeting and porous printed titanium cutting guides and plates produced by DePuy Synthes® using the TruMatch Synpliciti® system. We discuss the work flow required and the advantages (improved accuracy and reduced operative time) and limitations (cost and of the technology system. At present we understand this to the be the first use of this system in the UK.
