(TC18) Autotransplantation: A Viable Treatment Option for Patients With Significantly Compromised Teeth

Abstract: Autotransplantation can be a beneficial, low-risk alternative treatment for teeth requiring extraction. The selected donor tooth from the patient is usually one that is not in function or needs to be extracted for orthodontic purposes. This procedure requires thorough examination and treatment planning, and the technique involves the atraumatic extraction of both teeth, transplantation of the donor tooth into the recipient site, and splinting. Non-surgical root canal treatment should be performed before the splint removal (2 to 3 weeks). This clinical table presents three cases of autotransplantation: two mandibular molars and one maxillary premolar. The premolar and one molar were asymptomatic and stable after 12 months, and one of the molars for 4 years. The cases presented support tooth autotransplantation as a long-term treatment option, offering functional and esthetic benefits while preserving the patient’s own tooth. Three case reports are discussed: 1) A mandibular third molar transplanted into a second molar site, which was extracted due to an isolated deep pocket and the presence of a crack (1-year follow-up); 2) A mandibular third molar transplanted into a second molar site, which was extracted due to compromised restorability (4 years follow-up); 3) A mandibular premolar extracted for orthodontic reasons, transplanted into a maxillary premolar site, which was non-restorable and extracted (1-year follow-up).
