RESUMO
BACKGROUND: Dental autotransplantation (DAT) is a biological way of replacing missing or compromised teeth for patients. The techniques often necessitate a multi-disciplinary approach. The prognosis and success of the procedure may be impacted by variable factors in varying degrees. OBJECTIVE: Evaluating outcomes and complications of DAT, including prognostic factors using an umbrella review. SEARCH METHODS: Six databases were searched for all relevant systematic reviews published up to 30 June 2022. No restrictions were applied to language or publication date. SELECTION CRITERIA: Systematic reviews and meta-analyses of DAT studies. DATA COLLECTION AND ANALYSIS: Identification, screening, eligibility, and quality assessment using the AMSTAR 2 tool were performed independently by two authors (M.C. and S.A.). Two studies (20%) scored moderate, six studies (60%) scored low, and two studies (20%) scored critically low. Data were analysed using a random effects meta-analysis, and meta-regression was performed to investigate the effect of open and closed apices on the dependent variables. The results were summarised as relative risk ratios. RESULTS: A total of 310 studies were eligible for inclusion, of which 20 studies were selected for full-text evaluation. Ten systematic reviews were included, 9 of which had a meta-analysis. Overall findings suggest that DAT offers favourable success and survival rates. Meta-regression results indicate that a closed apex increased the proportion of ankylosis and resorption, reduced survival but had no effect on success during the observational period. LIMITATIONS: A varying degree of heterogeneity and bias was present in all systematic reviews. The samples of donor teeth included in the systematic reviews also varied morphologically. CONCLUSIONS: DAT is a technique-sensitive procedure requiring a multidisciplinary team, vigilant case assessment and thorough consideration of the respective prognostic factors involved. Despite methodological limitations reported across studies, DAT shows favourable success and survival rates, with a distinctive advantage of bone induction and soft tissue thickness preservation, and should, therefore, be considered as a viable treatment modality. Standardisation of clinical guidelines and practice are highly recommended. REGISTRATION: CRD42020202484.

Dental autotransplantation is an effective alternative to conventional dental treatment, and it involves removing a tooth and repositioning it in a new position within the same patient. Although this procedure might pose more intraoperative challenges, it provides a great solution for replacing missing teeth or aiding difficult eruption in young patients. This prospective method is also advocated as a use of treatment for unrestorable teeth. The success rates of autotransplantation cases with and without replicas were compared in a retrospective analysis of the data. By reducing donor tooth manipulation and ensuring a proper fit and positioning in the recipient socket, replicas significantly increased success rates of the procedure. CBCT scans were used to collect data. Data exported to the Mimics system were then processed in order to achieve a model of the donor tooth. Additive manufacturing technology was used to create the replicas. Specialized biocompatible material was used. Details of the replantation site and the donor tooth requirements were described, as well as the step-by-step surgical technique. For the best results, variables, like patient selection, surgical technique, and long-term monitoring, were found to be essential. The study highlights the significance of dental professionals and biomedical engineering staff working together to develop standard operating procedures and achieve predictable outcomes in autotransplantation procedures. The results suggest that 3D printed replicas could be a useful tool for improving the effectiveness and success of dental autotransplantation.
RESUMO
Dental autotransplantation is a dental treatment whereupon a natural donor tooth from the same person replaces a missing tooth at the recipient site. This treatment modality has been ignored by many clinicians for decades. This paper discusses the "poor" prognosis of autotransplantation of teeth with complete root formation as described in a recent publication. It delivers a straightforward message indicating that success and failure are multifactorial.
RESUMO
El trasplante dentario autólogo se define como el po-sicionamiento de una pieza dentaria autóloga en un alvéolo post extracción o en un lecho formado qui-rúrgicamente. Actualmente, siguiendo los criterios de selección adecuados y una técnica quirúrgica mi-nuciosa, resulta una alternativa terapéutica ideal en ciertos pacientes. La gran variabilidad de implantes dentales y alternativas de injertos óseos han resuelto el problema de sustituir una pieza dentaria perdida. En los pacientes en crecimiento o con potencial de crecimiento residual del proceso alveolar, se pone en evidencia el inconveniente que puede representar la colocación de implantes, lo que hace necesario ree-valuar la conservación de dientes y la utilización de técnicas quirúrgicas clásicas. Las tasas de éxito de los autotrasplantes autólogos han aumentado con el tiempo, alcanzando cifras mayores al 90%. En el pre-sente artículo se reporta un caso clínico de autotras-plante dentario con planificación digital y una réplica tridimensional de la pieza a trasplantar (AU)
Autologous tooth transplantation is defined as the positioning of an autologous tooth in a post-extraction socket or in a surgically formed bed. Currently, following the appropriate selection criteria and a meticulous surgical technique, it is an ideal therapeutic alternative in certain patients. The great variability of dental implants and bone graft alternatives have solved the problem of replacing a lost tooth. In growing patients or with potential for residual growth of the alveolar process, the inconvenience that implant placement can represent is evident, which makes it necessary to reevaluate tooth conservation and the use of classic surgical techniques. The success rates of autologous autologous transplants have increased over time, reaching figures greater than 90%. This article reports a clinical case of dental autotransplantation with digital planning and a three-dimensional replica of the piece to be transplanted (AU)

RESUMEN: La técnica de autotrasplante dental se ideó como opción terapéutica ante la pérdida o ausencia de dientes por traumatismos, caries, agenesias, exfoliación temprana, iatrogenias, u otros factores. Consiste en extraer un diente desde su posición original para implantarlo en un solo acto quirúrgico en una zona edéntula, sea ésta un alveolo postextracción o alveolo confeccionado quirúrgicamente. Un resultado exitoso, requiere una meticulosa selección de candidatos, para esto, se debe considerar la ausencia de patologías y condiciones de orden local o sistémico que dificulten una adecuada cicatrización de heridas y reparación tisular. Nuevas herramientas para facilitar éxito clínico, como la planificación y simulación virtual, junto con la impresión de prototipos en tres dimensiones (3D), permitirían optimizar posibles osteotomías y una implantación del diente donante de manera fácil y en tiempos quirúrgicos mínimos, favoreciendo la disminución de la complejidad quirúrgica, además de la reparación y regeneración de tejidos pulpares y periodontales. El objetivo de este artículo es reunir una serie de consideraciones para optimizar la técnica de autotrasplante dental.
ABSTRACT: The dental autotransplantation technique was devised as a therapeutic option for the loss or absence of teeth due to trauma, caries, agenesis, early exfoliation, iatrogenesis, or other factors. It consists of extracting a tooth from its original position to implant it in a single surgical act in an edentulous area, be it a post-extraction socket or a surgically made socket. A successful result requires meticulous selection of candidates, for this, the absence of pathologies and local or systemic conditions that hinder adequate wound healing and tissue repair must be considered. New tools to facilitate clinical success,such as planning and virtual simulation, together with the printing of prototypes in three dimensions (3D), would allow possible osteotomies and an implantation of the donor tooth in an easy way and in minimal surgical times, favoring the decrease of surgical complexity, in addition to the repair and regeneration of pulp and periodontal tissues. The objective of this article is to gather a series of considerations to optimize the dental autotransplantation technique.
RESUMO
Antecedentes: los autotrasplantes dentales son una técnica que se ha utilizado durantemucho tiempo; sin embargo, son poco utilizados por las múltiples variables que determinansu éxito y la falta de unificación de criterios en la técnica. Objetivo: identificar, por medio deuna revisión sistemática de la literatura, las tasas de éxito de los autotrasplantes dentalesy algunos de los factores que modifican dichas tasas. Método: se realizó una búsqueda deliteratura sobre autotrasplantes dentales en revistas incluidas en las bases de datos biomédicasMedline, EMBASE, CINAHL, Scisearch y PsycLIT, así como en bases de datos electrónicascon un foco específico como Cochrane Controlled Trials Register de la Cochrane Library,Health Technology Assessment y NHS-EED. Se elaboraron medidas de resumen y evaluaciónde la calidad metodológica mediante el programa Revman 5.
