J Oral Maxillofac Surg. 2013 Dec;71(12):2154.e1-9. doi: 10.1016/j.joms.2013.07.012. Epub 2013 Sep 14.


A new technique of model surgery using LEGO plates as key-spacers is described. This technique requires less time to set up compared with the conventional plaster model method. It also retains the preoperative setup with the same set of models. Movement of the segments can be measured and examined in detail with LEGO key-spacers.
