Resumen
La presente propuesta de investigación hace referencia a los
factores a evaluar para la selección de los pilares en prótesis
dental fija. Entre ellos consideráramos, la Proporción coronaraíz:
es una medida de la longitud del diente, desde oclusal
hasta la cresta ósea alveolar, en contraposición a la longitud
de la raíz dentro del hueso. La proporción corona-raíz para un
diente que ha de actuar de pilar de una prótesis parcial fija es
de 2:3. Una proporción de 1:1 es la mínima aceptable para un
futuro pilar en circunstancias normales. También hay que
considerar la configuración de la raíz o radicular: las raíces
más anchas vestibulolingualmente que mesiodistalmente son
preferibles a las raíces que tienen una sección redonda. Los
dientes posteriores multirradiculares con raíces muy separadas
ofrecerán mejor soporte periodontal que las raíces
convergentes, fusionadas o con una configuración cónica se
puede usar como pilar cuando hay un espacio edéntulo corto
siempre que los factores sean óptimos. Zona del ligamento
periodontal: cuando se ha perdido hueso de soporte dentario
por una enfermedad periodontal, los dientes afectados tienen
menos capacidad para servir de pilares. Es por ello que el
tratamiento planificado se debe tener en cuenta. La longitud
del póntico que puede restaurarse con éxito viene limitada, en
parte por los dientes pilares, y en parte por su capacidad para
aceptar la carga adicional. Es importante considerar la ¨ley de
Ante¨ en la planificación de nuestros tratamientos, la
superficie radicular de los dientes pilares debe ser mayor o
6
igual a la de los dientes a sustituir con pónticos. De acuerdo
con esta ley , un diente ausente puede sustituirse con éxito
siempre que los dientes pilares estén sanos.
This research proposal refers to the factors to evaluate for the selection of the pillars of fixed dentures. Among them we considered the crown-root ratio: A measure of the length of the tooth from occlusal to the alveolar bone crest, as opposed to the length of the root into the bone. The crown-root ratio for a tooth that has to act as the pillar of a fixed partial denture is 2:3. A ratio of 1:1 is the minimum acceptable for a future mainstay in normal circumstances. Also consider the configuration of the root or root: root wider than mesiodistally labiolingually roots are preferable to having a round section. Multi-rooted teeth with roots after separate periodontal offer better support converged roots, merged, or with a conical configuration can be used as a pillar when a short edentulous space where the factors are optimal. Periodontal ligament area: when you've lost tooth supporting bone for periodontal disease, the affected teeth are less able to serve as pillars. That is why the planned treatment should be taken into account. The length of the pontic can successfully restored is limited, partly because of the abutments, and in part by their ability to accept the additional load. It is important to consider the ¨ ¨ First law of our treatment planning, the root surface of the abutment teeth must be greater than or equal to that of the teeth to be replaced with pontic. According to this law, a missing tooth can be successfully substituted where the abutment teeth are healthy.
