RESUMEN

Introducción: el autotrasplante dentario se efectúa con mayor frecuencia en pacientes con traumatismos dentoalveolares. En los casos de pérdidas dentarias por otros motivos actualmente se emplea el implante osteointegrado, por lo que el primero ha quedado relegado.Objetivo: presentar el caso de un paciente al que se le realizó autotrasplante de un canino superior como opción terapéutica correctora de la maloclusión.Presentación del caso: paciente femenina, de 22 años de edad, con el canino superior izquierdo retenido. Seis meses atrás se le realizó un enlace durante un tratamiento activo en ortodoncia. En la radiografía se observó el canino impactado y angulación que dificultaba el movimiento ortodóncico. En la intervención quirúrgica se empleó la técnica de autotrasplante canino. No tuvo complicaciones quirúrgicas y evolucionó satisfactoriamente.Discusión: la retención dentaria se caracteriza por la falta de erupción del diente y un conjunto de alteraciones. Se presenta con mayor frecuencia en adolescentes y adultos jóvenes, y se relaciona con la erupción de los terceros molares y los caninos. El tratamiento de elección es la recolocación del diente incluido en la arcada dentaria, y se puede hacer mediante procedimientos quirúrgicos-ortodóncicos o quirúrgicos.Conclusiones: el autotrasplante dentario es una opción viable para tratar las maloclusiones. La funcionalidad del diente trasplantado fue buena, así como su estética e integración. Aunque el uso de esta técnica está limitado al diente donante, si este reúne las condiciones para ejecutar el trasplante, se debe considerar su realización(AU)

Introduction: dental autotransplant is performed more frequently in patients with dentoalveolar trauma. In cases of dental losses for other reasons, the osseointegrated implant is currently used, so the former has been relegated.Objective: to present the case of a patient who underwent autotransplantation of an upper canine as a therapeutic option to correct malocclusion.Case presentation: female patient, 22 years old, with the left upper canine retained. Six months ago a tie was carried out during an active treatment in orthodontics. The x-ray showed the impacted canine and angulation that made orthodontic movement difficult. In the surgical procedure, the canine autologous technique was used. She had no surgical complications and evolved satisfactorily.Discussion: dental retention is characterized by the lack of eruption of the tooth and a set of alterations. It occurs most frequently in adolescents and young adults, and is related to the eruption of third molars and canines. The treatment of choice is the relocation of the tooth included in the dental arch, and can be done through surgical-orthodontic or surgical procedures.Conclusions: dental autotransplantation is a viable option to treat malocclusions. The functionality of the transplanted tooth was good, as well as its aesthetics and integration. Although the use of this technique is limited to the donor tooth, if it meets the conditions to perform the transplant, it should be considered(AU)

RESUMEN

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

RESUMEN

Avaliamos um grupo de nove (9) pacientes, de ambos os sexos, portadores de caninos superiores retidos uni ou bilaterais, submetidos a técnica cirúrgica de transplantes autógenos. Após a realizaçäo do exame clínico e radiográfico optamos pela técnica dos transplantes autógenos devido a falta de condiçöes econômicas do paciente e sua näo disposiçäo em submeter-se a tratamentos prolongados e/ou ortodônticos. Também levamos em consideraçöes os casos de contraindicaçöes ortodônticas, as quais impossibilitam o tratamento preferencial, ou seja, exposiçäo cirúrgica e traçäo ortodôntica combinadas. Na avaliaçäo dos dados obtidos verificamos que para a obtençäo de um bom resultado dos transplantes autógenos é necessário, principalmente, condiçöes locais apropriadas, correta localizaçäo radiográfica, evitar traumas na porçäo radicular do canino transplantado, cooperaçäo do paciente no pós-operatório, e a näo realizaçäo do tratamento endodôntico tras ou pós-operatorio imediato. Conclui-se que os transplantes autógenos de caninos superiores retidos é uma técnica cirúrgica que apresenta bons resultados, mas nunca deve ser uma técnica preferencial, mas alternativa, nos casos de retençöes de caninos
