Introduction: Tooth auto-transplantation has a high success rate therapy when limiting the extra-oral time of the graft. In this way, printing a 3D model of the germ can be a useful tool in order to prepare the receiving site. Observation: We treated a case of post extractional oro-sinusal communication closure using a 3D pattern to adapt the alveolar socket receiving the wisdom tooth auto-transplantation. Comment: Extra-oral time spent by the graft was under 15 seconds improving the chance of success. After one year follow up, the graft is vital, functional and it continued its root formation. Conclusion: 3D printing seems to be an effective technique to minimize surgical time leading to a higher rate of success for auto-transplantation therapies.
