Abstract

BackgroundIn medicine and dentistry, 3D technology allows the virtual planning and printing of surgical replicas of anatomical structures that can facilitate certain transplant procedures. In dentistry, 3D technology is useful in autogenous tooth transplantation.Case presentationWe present a clinical case of an ectopic mandibular second premolar, describing the preoperative planning with dental replicas and the autotransplantation surgery. 3D prints of the surgical replica of the tooth to be transplanted was made using an Objet30 Prime® Printer, PolyJet. Clinical controls performed at 3, 6 and 12 months indicated the satisfactory evolution of the transplanted tooth.Conclusion3D additive manufacturing technology allows the preparation of a new recipient socket with the aid of a surgical replica of the tooth to be transplanted, thus minimizing handling and extraoral time.

Highlights

In medicine and dentistry, 3D technology allows the virtual planning and printing of surgical replicas of anatomical structures that can facilitate certain transplant procedures
In severe cases with poor prognosis, autogenous tooth transplant is considered as a therapeutic alternative to surgical removal of the ectopic tooth
We describe a case of autogenous tooth transplant using replicas of the donor tooth, 3D printed with Polyjet technology, for use as a surgical guide in the creation of the recipient socket

Summary

Background

Ectopic tooth eruption is an alteration of the eruptive process that most frequently affects the third molars and the upper canines [1,2,3]. The process named 3D additive manufacturing technology consists of building a three-dimensional object directly using a 3D model in any type of file (e.g., STL, 3MF, STP), usually by the successive addition of material layer upon layer [12] This technology allows the printing of dental replicas for use as guides during surgery, minimizing extraoral time and limiting probable damage to the periodontal tissue of the donor tooth [11]. We describe a case of autogenous tooth transplant using replicas of the donor tooth, 3D printed with Polyjet technology, for use as a surgical guide in the creation of the recipient socket. Periodical clinical-radiological controls were performed at 1 month and at 3, 6 and 12 months (Fig. 7)
