Guided Tooth Autotransplantation
Tooth loss usually occurs after periodontal pathology, vertical root fractures, carious destruction and trauma. Autotransplantation of teeth is a technique that includes surgical creation of an artificial socket or utilising freshly extracted tooth socket and reposition an autogenous erupted or unerupted tooth to reestablish the primary role of dentition in terms of function, speech and aesthetics (1,2)
While preserving donor tooth “PDL” seems to be the key factor for success (4,5) some researchers found that immature teeth have a better prognosis in autotransplantation as they could promote revascularization easily than mature teeth (3), several case report studies have also reported high- success rates for autotransplantation of mature teeth (6–8) and 98.0% and 90.5% at 1 and 5 years, according to systematic reviews (6). Previous researchers found out that having a printed donor tooth (3D replica) prior extraction could optimise the total time of the procedure and most importantly it would decrease the donor tooth extraoral time (9). With digital planning and the CBCT, freshly extracted sockets are not a limitation anymore if the whole procedure is planned well and the procedure performed fast (12). Anssari Moin et al. described a method of computer- assisted template-guided autotransplantation with custom 3D designed/ printed surgical tooling (13) and few years later Abella et al. went even further with a custom designed osteotome and a fully exposed buccal wall of the donor tooth (14).
In this presentation the author will demonstrate how to plan and perform autotransplantation in different clinical situations by the use of modern technology and still be supported by the literature.
Accidental tooth loss is more frequent in younger persons than adults. Treatment of a missing tooth/teeth with an implant in adults is an excellent and predictable method of choice, but contraindicated in growing individuals as it does not provide further growth of the alveolar ridge vertically as natural dentition tends to. Follow-up studies of cases with missing incisors in growing patients have shown that in long-term perspective, prosthetic rehabilitation was the least desired treatment option compared to orthodontic space closure and autotransplantation.
Performing a successful implant procedure in a compromised recipient socket with a significant bone loss and/ or sinus lift in adults is a very challenging task even for the most experienced clinicians. Having an available fresh socket or bone height/ width makes the procedure fast and predictable. On the other hand if there is a soft and hard tissue deficiency, autotransplantation could be advantageous to implants mainly because of the “PDL ” osteoinductive potential and optimal biologic interactions with soft tissue.

Check Out Our Videos of Past Years’ Events
Our two-decade history is worth looking back. What started as an idea at an exhibition 22 years ago has now become a defining dental event. But its success has also required the contribution of many colleagues and supporters. They are also remembered in these few videos – which shows our progress – and allow you to rewind the clock to the beginnings.
