Autotransplantation of Two Immature Third Molars with the Use of L-PRF

Abstract

Tooth autotransplantation is a procedure which provides the extraction of an erupted or impacted tooth and its repositioning to another site in the oral cavity. This Case Report describes a successful case of two autotransplantations of open-apex mandibular third molars in place of the hopeless first mandibular molars with the use of L-PRF in a growing patient. A 15-year-old male patient was referred to the Dental Clinic for the extractions of the two hopeless mandibular first molars. Autotransplantation was considered the best treatment option for both sites 36 and 46, because the presence of two impacted mandibular third molars (38 and 48) with an incomplete root formation. Teeth 36 and 46 were extracted and replaced with teeth 38 and 48. The patient had an uneventful healing. At follow-up visits, the two autotransplanted teeth showed physiologic mobility, absence of inflammation and discomfort, and absence of infection; probing depth values were within normal range, and the vitality tests were positive. After 2 years, the teeth in position 36 and 46 showed absence of infection and mobility, and positive pulp vitality tests and the radiographic examinations exhibited closure of the root apices as well as absence of any periapical radiolucency or root resorption. Tooth autotransplantation is a good treatment option in case of tooth loss offering an alternative to traditional or implant-supported prosthesis especially for growing patients.

Autotransplantation of the Third Molar: A Therapeutic Alternative to the Rehabilitation of a Missing Tooth: A Scoping Review

“…The results of this review of meta-analyses were partially confirmed by a study by Tang et al 2017 [ 25 ] and many case reports (Jang et al 2013 [ 9 ], Rey Lescure 2021 [ 24 ]). A subsequent study by Lucas-Taulé et al 2021, which reported rates of success in both open and closed apexes of 92–97%, concluded that the state of maturation of the root does not correlate with the success rate [ 23 ].…”

Success of a tooth auto-transplant despite delayed endodontic treatment due to COVID-19 pandemic lock-down: a case report

“…Not only, does it require a high level of expertise in the field by the operator, proper clinical and radiological investigation but also, patient factors such as age, dental hygiene and underlying illnesses play an essential role in treatment success [22,25]. It is extremely essential that an atraumatic extraction should be carried out from both, the donor and recipient site of auto-transplantation, to preserve the surrounding periodontium, especially the bone of the socket and periodontal ligament fibers attached to it [24,26].…”
