Abstrakt:	Patients with rapidly progressing periodontitis may require extractions of teeth with poor periodontal prognosis. Although replacement with a dental implant is a popular choice, teeth autotransplantation remains a viable option. Herein, we report a case of a 23-year-old patient with rapidly progressing periodontitis resulting in severe clinical attachment loss on the left maxillary first molar, which required extraction. The tooth was replaced by tooth autotransplantation of the unerupted immature left mandibular third molar, which was delivered carefully without compromising the periodontal ligament. Cone beam computed tomography and three-dimensional printing of the third molar donor tooth significantly aided the tooth autotransplantation procedure. Recovery was uneventful. At the 1-year follow-up, healthy periodontal parameters and radiographic features were noted, and the autotransplanted tooth remained vital. This case showed that tooth autotransplantation is a viable option for replacing tooth loss due to rapidly progressing periodontitis. Competing Interests: Competing interests: None declared.
