Resumen
Los dientes tratados endodonticamente eran considerados frágiles y se creía que con la utilización de retenedores intra-radiculares se reforzaría la estructura dentaria. Actualmente la función de un poste está más relacionada a la retención del material restaurador, sin ninguna pretensión de reforzar la estructura radicular remanente. Existe una gran variedad de postes disponibles en el mercado, desde los metálicos fundidos hasta los pre-fabricados. Los postes pre-fabricados pueden ser metálicos, cerámicos o reforzados con fibras, ya sea de carbono o de vidrio. Los postes de fibra de vidrio están siendo actualmente indicados en la práctica odontológica, debido a su excelente estética, asociada a su fácil manipulación, adecuada resistencia mecánica y buena relación costo/beneficio. El presente trabajo pretende mostrar a través de una revisión de literatura, las principales características clínicas, propiedades físicas - mecánicas, ventajas y limitaciones de los postes pre-fabricados, con la finalidad de facilitar su indicación en la odontología clínica. (Alberth M. Correa, 2007, Pág. 99-103). Uno de los retos en la selección de pilares, es precisamente la valoración de los mismos para que estos nos brinden la seguridad y confianza en la sobrevivencia no solo de las prótesis, sino tal vez más importante aún de ellos mismos, para lo cual es importante el estudio y comprensión de las estructuras periodontales en su biología, fisiología y determinados aspectos anatómicos, ello nos permitirá el escoitamiento adecuado en lo cuantitativo y cualitativo, del o los pilares.

The fiberglass poles are being currently indicated in dental practice, due to its excellent aesthetics, easy handling associated with suitable mechanical strength and good cost / benefit ratio. This paper aims to show through a literature review, the clinical characteristics, physical - mechanical properties, advantages and limitations of pre-fabricated posts, in order to facilitate their indication in clinical dentistry.

One of the challenges in selecting pillars is precisely the evaluation of them so that they give us security and confidence in the survival not only of the prosthesis, but perhaps more importantly themselves, for which it is important the study and understanding of periodontal structures in biology, physiology and certain anatomical aspects, this will allow us the right escoitamiento quantitatively and qualitatively, the or pillars
