Canine impaction and migration is conventionally managed by fixed orthodontic treatment with surgical exposure; however this is not always possible, thus requiring clinicians to explore other treatment options. Autotransplantation of the tooth has been recognized as an alternative treatment option. This article reports on two cases where a migrated canine was asymptomatic, and accidentally diagnosed during routine examination. The procedure undertaken was autotransplantation of the canine using a physio-dispenser system and a platelet-rich fibrin (PRF) membrane to promote bone and soft tissue healing and regeneration. After a 2-year follow up, the autotransplanted canines showed no signs or symptoms of clinical or radiological failure. On radiographic examination, a patent periodontal ligament space was also appreciated.
CPD/Clinical Relevance: Use of a physio-dispenser system and PRF during autotransplantation of a migrated and impacted canine may improve the clinical outcome.
Article
A tooth can be surgically relocated within the same patient via a procedure called autotransplantation. It can be described as a controlled replantation of an extracted tooth into a new, surgically prepared socket.1 It can be interpreted as the meticulous replantation of a retrieved tooth into a fresh socket that has undergone surgery. The preservation and regeneration of the periodontal ligament is essential for the treatment's success. Patients with failing or missing teeth may find autotransplantation to be the best course of treatment when carried out by a multidisciplinary team.
Various reasons could necessitate an autotransplantation procedure, such as teeth with advanced caries, avulsed young permanent teeth and congenitally missing teeth (tooth agenesis).2,3 Autotransplantation may also be considered as a treatment option for atypical tooth eruption, as in the case of impacted and migrated canines.
Impacted canines can be managed by surgical exposure followed by fixed orthodontic therapy; however, it may not be possible to use that treatment option in cases of a migrated canine. In these situations, an easier and more rapid therapeutic option would be an auto-transfer of the canine into a more favourable position. Hale et al in 1965 were the first to document autogenous tooth transplantation and their methodology is still being practised to date.4
