This case report describes a novel approach of guided autotransplantation of tooth so that we can assess its feasibility, accuracy, and stability. In the present case, autotransplantation of a third molar at the recipient site of mandibular first molar was done. Three-dimensional (3D) replica of donor tooth along with surgical guiding template was virtually designed and fabricated using 3D printing. The 3D replica and surgical template helped in the surgical modification of recipient site and placement of donor tooth in the exact position. Root canal treatment of the donor tooth was carried out after 2 weeks. At 6 months' follow-up, the transplanted tooth was functional with no evidence of mobility or periodontal inflammation. Radiographic evaluation showed the absence of widening of periodontal space and external root resorption. Hence, the transplantation of the third molar is an outstanding procedure for replacing a lost permanent molar tooth which in turn restores esthetics and function.
