In prehistoric era archeological evidences suggest that cranial defect (Trephination) reconstruction was done with gold, silver and shells. The next advancement was the use of bone grafts in late 19th century. In 20th century alternatives of bone graft, metals and plastics were used. Cranial reconstruction can be done by auto grafts, allograft, distinct biomaterials, and even osteoinductive growth factors. Polymethylmethacrylate (PMMA) is one of the most popular materials used for cranioplasty. But attainment of desired shape, size and cosmesis is difficult. This problem can be solved with the help of 3 dimentional printing technology, using prefabricated model (template) to prepare implant preoperatively. In this case report, we developed a computer-generated model (template) using the 3D Object printer. A mould (template) was created and it was used intraoperatively to produce a PMMA-alloplastic cranial implant that was well fitted into the anatomical defect. A well-fitted implant improves cosmetic outcome, self confidence and reduces the risk of implant movement or extrusion. 3D printed model helps us to provide exact dimensions of the bony defect along with good cosmesis, accuracy and strength of the anatomic replacement.
