Introduction: In this lecture authors describe their own clinical experience in autologous tooth replantation using STL printed replica with monitoring of revascularization, the pulp healing process and clinical manifestations, which are important factors for the future viability of the replanted tooth.

Content:Autologous tooth replantation is one of the treatment options for extracted and missing teeth. Although dental transplantation success is generally lower than for titanium implant replacement, dental replantation should be preferred in situations where a patient has a suitable intact tooth that meets the conditions for proper healing into a suitable and pre-prepared alveolar maxillary or mandible implant bed. Such treatment is an accepted way to replace a missing tooth in certain cases where any conventional treatment of the original tooth is unreliable and difficult to implement either due to anatomical limitations, dystopic tooth abnormalities, ongoing pathological process, extensive cavity lesions or traumatic changes. An irreplaceable benefit in this issue is the collection of data using 3D technology in order to create an accurate replica of the replanted tooth. Thanks to CBCT examination and subsequent conversion of this data by stereolithography (STL), it is possible to create a 3D replica of the tooth to be replanted on a 3D printer. The whole 3D printing process takes two to three hours. This DLP (Digital Light Processing) technology uses a type of liquid resin that cures lightly to a solidifying layer in a final transparent model that can be used during surgery after proper disinfection.

Conclusion: The main advantage of this method is the shortening of the extraalveolar time of the implant to the lowest possible level, which guarantees the greatest chance of maintaining tooth vitality and also the possibility to perform replantation of deeply retained, impacted or excessive teeth. The authors describe their own clinical experience in autologous tooth replantation using STL printed replica with monitoring of revascularization, the pulp healing process and clinical manifestations, which are important factors for the future viability of the replanted tooth.
