ABSTRACT

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)

ABSTRACT

Dental transplantation is a treatment used to replace a missing tooth with another tooth. It is autogenous when it comes from the same individual. The aim of this article is to discuss the surgical protocol and present a case study to optimize the technique for the general dental practitioner. The first molars are the first permanent teeth to erupt during infancy, they are teeth most commonly lost among the permanent dentition. The third molars are best suited for this treatment, the treatment should be undertaken as soon as possible, as the patient ages there is decrease in the mesenchymal cells. Whenever possible, the pericoronal bag should be preserved in the removal of the tooth germ or tooth formed. We present a case where the tooth was placed in the receiver socket, taking into account the anatomical orientation of its faces, in infra-occlusion. The contention was made by silk and point "X" on the occlusal graft and fixed to the adjacent teeth with light-cured resin. Transplantation is an excellent alternative for treating the loss of one molar, especially in young patients.

ABSTRACT

El autotrasplante se refiere a la transferencia quirúrgica de un dientede una posición a otra en el mismo individuo dentro de los alveolosde dientes extraídos o sitios preparados quirúrgicamente. El autotrasplante de un diente inmaduro puede ser una opción para reemplazarmolares con caries extensas en pacientes jóvenes como una alternativaal reemplazo de dientes con prótesis fi ja o implanto-soportada. Es unprocedimiento clínico con un índice de éxito de 98 por ciento cuando los dientes son trasplantados traumáticamente y el tiempo extraoral se mantiene al mínimo. El estado de desarrollo del diente determina ampliamente el potencial de reparación pulpar después del autotrasplante. Para obtener una pulpa vital en un diente autotrasplantado el foramen apical no debe medir menos de1 mm de diámetro. El área receptora debe ser 1-2 mm más grande y profunda que las medidas de las raíces donadoras parapreservar las células del ligamento periodontal, un óptimo contacto entreambas estructuras puede mejorar el suministro sanguíneo y los nivelesde nutrición de las células del ligamento periodontal, el cual puedeincrementar el éxito del autotrasplante. En este artículo se presenta un caso exitoso de autotrasplante de tercer molar inmaduro.


Autotransplantation refers to the surgical transfer of a tooth fromone position to another in the same individual onto extracted toothsockets or surgical prepared recipient sites. Autotransplantation of animmature teeth can be an option to replace extensive decayed molarsin young patients as an alternative to immediately replacing teeth withfi xed or implant-supported prosthesis. Autotransplantation is a clinicalprocedure with a success rate of 98% when teeth are transplantedatraumatically and when the extraoral time is keep to a minimum.The developmental stage of the tooth highly determines the potentialof pulpal repair after transplantation. To obtain a vital pulp in anautotransplanted tooth, the apical foramen should not be smaller than1 mm in diameter. The recipient area must be 1-2 mm larger and deeperthan the measurements of the donor roots to preserve the periodontalligament cells, an optimal contact between both structures can improvethe blood supply and the level of nutrition to the periodontal ligamentcells, which can increase the success of autotransplantation. In thispaper, we report one case of successful autotransplantation of animmature third molar.

ABSTRACT

This paper describes the autologous transplantation of a mandibular right third molar to replace the residual roots of the second molar in the same quadrant, preserving function and aesthetics. A 5-year clinical and radiographic follow-up was undertaken. After transplantation, the donor tooth received endodontic treatment and placement of calcium hydroxide, which was periodically replaced every 3 months until the filling of the root canals, totalizing a period of 1-year, when apical closure was confirmed. The tooth was in perfect functional and aesthetic conditions 5 years after beginning of treatment. Autotransplantation is a feasible option for replacing missing teeth when a donor tooth is available. The autotransplantation of a right mandibular third molar with compromised function and aesthetics to replace the residual roots resulting from coronal destruction due to extensive carious lesion of the second molar in the same quadrant was a viable treatment alternative.


O objetivo deste trabalho foi descrever o transplante autógeno de um terceiro molar inferior direito para substituir as raízes residuais do segundo molar no mesmo quadrante, preservando a função e a estética. Foi realizado acompanhamento clínico e radiográfico por 5 anos. Após o transplante, o dente doador recebeu tratamento endodôntico e colocação de hidróxido de cálcio, o qual foi substituído periodicamente a cada 3 meses, até a obturação dos canais radiculares, totalizando período de 1 ano quando então, o fechamento apical foi confirmado. O dente encontra-se em perfeitas condições funcionais e estéticas após 5 anos do início do tratamento. O autotransplante é uma opção viável para a substituição de dentes perdidos quando um dente doador está disponível. O autotransplante de um terceiro molar inferior direito com comprometimento estético e funcional afim de substituir raízes residuais (resultado de um processo cariogênio extenso) de um segundo molar do mesmo quadrante foi um tratamento alternativo viável.

ABSTRACT

To determine the success rate in autotransplantation of endodontically treated third molars. Design: A descriptive study. Place and Duration of Study: This study was carried out at Armed Forces Institute of Dentistry [AFID], Rawalpindi [Pakistan] from January 2002 to December 2002. Patients and A total of 50 patients meeting the inclusion criteria were selected who had their first or second molars in unrestorable condition with intact third molars. The donor teeth were extracted after the preparation of recipient site. After endodontically treated in vitro the donor teeth were carried to the recipient site and immobilized. Postoperative variables were recorded and analyzed on SPSS version 10. The overall success rate after six months of the transplantation of third molars was 88% with complete root formation after endodontic treatment. All the patients[12%] who had complaints were more than 35 years of age. Third molars are good substitute for the unrestorable first or second molars and would be as effective as endosseous implants. The procedure is likely to have complications in the advanced age group

ABSTRACT

Entre 13 a 20 anos os dentes mais freqüentemente extraídos säo os primeiros e segundos molares. A extraçäo prematura está associada a doenças periodontais precoces, fraturas radiculares e lesöes de cárie. Para se evitar problemas de maloclusäo é importante a manutençäo do espaço deixado pelo dente extraído. Um tratamento alternativo para a reposiçäo desses dentes é o transplante do germe do terceiro molar para o lugar do primeiro ou segundo molar, uma vez que o terceiro molar apresenta desenvolvimento tardio em relaçäo aos outros dentes. O transplante autógeno pode ser realizado através de duas técnicas cirúrgicas distintas, a imediata, quando a cirurgia é realizada em uma única sessäo e a mediata realizada em duas sessöes com intervalos de 15 dias entre as sessöes. Sendo assim, o objetivo deste trabalho é através de casos clínicos, ilustrar a técnica de transplante autógeno de germe do terceiro molar, discutindo suas indicaçöes e vantagens

ABSTRACT

O estudo que segue avaliou o prognóstico da substituiçäo de molares por transplante autógeno de terceiros molares em diferentes estágios de desenvolvimento radicular. A amostra constitui-se de cinco pacientes com idade variando entre 17 e 29 anos. Os elementos dentais com formaçäo radicular completa sofreram intervençäo endodôntica, após duas ou três semanas ao transplante dental. O acompanhamento dos casos clínicos inclui profundidade à sondagem, nível de inserçäo, teste à percussäo (som) e teste de vitalidade. As radiografias foram padronizadas pela técnica do cone longo e obtidas ao final do procedimento cirúrgico, e após três, oito, vinte e quatro semanas e um ano da cirurgia de transplante dental

ABSTRACT

Se realizó un estudio prospectivo de 8 autotrasplantes y 2 reposiciones dentales en 8 pacientes que consultaron entre agosto de 1994 y abril de 1996, los que se controlaron en el período de un año. Se evaluaron parámetros clínicos como dolor, cambio de color, sangrado, movilidad e índice de Russell, también se evaluaron parámetros radiográficos como espacio del ligamento periodontal, reabsorción radicular interna y externa, obliteración de la cámara pulpar y estadio de desarrollo radicular. Todos los casos se realizaron de diferentes dientes donantes a diferentes sitios receptores, notándose que los autotrasplantes más frecuentemente realizados son del tercer molar al primer molar y las reposiciones en zona de premolares. La tasa de supervivencia fue del 100 por ciento a los seis meses y del 75 por ciento a los 12 meses, teniendo en cuenta que no todos los casos han completado los períodos de control. Uno de los autotrasplantes no sobrevivió aunque se le intentó realizar tratamiento pulpar con hidróxido de calcio. Los resultados iniciales de este estudio piloto demuestran que los autotrasplantes y las reposiciones dentales son alternativas de tratamiento con altos porcentajes de éxito en caso de pérdida dentaria o alteración en la erupción por malposición

ABSTRACT

Dental transplants are of great interest in modern dentistry. Research has been directed toward the study of different techniques and observations of the results. Scientific basis is also to be observed and the aim of this paper is to associate technical with scientific data. Dental germs in different stages of development were carefully removed from their alveolar cavities together with the dental sac. Trauma was observed in some areas resulting from the movements of extraction or of the removal of the dental sac by dissection. It should be noticed that by the trauma produced by removal of the dental sac is very uncommon, since the operation is performed at a mesoscopic level. The material showed that the periodontal collagen net is complex in form and the meshes are wider in the surface. Smaller meshes could be seen closer to the cementum surface. Measures could be taken in order to have a basis of the distribution of collagen material around the dental root in different levels. The results showed that extraction should be performed in a most conservative manner and the movements for extraction should be applied to the crown of the dental germ. The maintenance of the periodontal integrity is very important in order to preserve the vascular barrier created by the dental cementum

ABSTRACT

O proposito deste trabalho foi analisar, atraves de um estudo clinoco e radiografico, 43 autotransplantes de terceiros molares de humanos com rizogenese completa para diferentes areas. Foram selecionados 40 pacientes com idade media de 29 anos (19 a 65). Todos os dentes foram extraidos com extremo cuidado, com tempo extra-alveolar de no maximo 15 segundos, sendo mantidos com fixacao semi-rigida atraves de sutura e cimento cirurgico por 3 a 4 semanas e com completo controle de placa. Os tratamentos endodonticos foram realizados em todos os dentes transplantados, com intervalos variaveis de 25 a 575 dias, com media de 135. Ate o final do periodo de observacao, 7 dentes foram condenados. Os 36 restantes, apresentaram-se com funcao e saude satisfatorias, condizentes com os demais dentes da boca de cada paciente. Ainda que o numero de casos seja reduzido, e demonstrado neste trabalho a viabilidade de transplantes autogenos de dentes com rizogenese completa. Contudo, convem salientar que uma serie de variaveis interdependentes devem ser respeitadas para a manutencao da integridade da membrana periodontal e consequente sucesso do auto transplante
