Premaxillary tooth loss and bone deficiency or atrophy often occur in facial trauma. Onlay bone graft and implants have so far been the best means of restoring function and esthetic appearance. Void space between the graft and the jaw bone, over projection and mucosal trauma can cause mucosal dehiscence, bone exposure, or resorption and can compromise implant survival. Virtual surgical planning using 3-dimensional printing technology has improved the efficiency of craniofacial surgery. The drawbacks of this technology are its cost and time-consuming preparation. However, the democratization of high-performance 3-dimensional printing and open-source software have enabled surgeons to master the procedure. The authors applied this innovative technology to customize bone graft for insertion of a premaxillary implant. It enabled us to custom-make the bone graft on the template and to perfectly embed the graft in the gap with a reduce operating time and a good osteointegration.
