ABSTRACT

Pese al innegable incremento en la utilización de implantes óseo integrados en el tratamiento de la extensa problemática de la desdentación parcial, la confección de prótesis removibles metálicas continua siendo a escala mundial, el principal recurso terapéutico vigente. Sin embargo, desde el punto de vista del paciente, la recuperación de la función estética es su principal falencia. Proponemos entonces, extender la utilización del principio de retención friccional inherente a la prótesis fija, mediante la preparación de "facetas retentivas friccionales" en ciertos dientes pilares, generando de este modo artificios protésicos removibles con suficiente retención, sin exhibir elementos metálicos en los sectores anteriores de la cavidad bucal. Se exponen cinco casos clínicos que respaldan la validez nuestra propuesta tras una correcta indicación (AU)


Despite the fact that nowadays the use of Osseo integrated implants is increasing worldwide nevertheless removable partial dentures with cast metal frameworks is still the most indicated treatment for cases of partial edentulism. However, patients remain reluctant regarding the aesthetic impairment brought by some of the removable partial dentures' components. Therefore we propose to apply to removable partial dentures some of the frictional retention's principles used in fixed prostheses, preparing instead of conventional guiding planes in some abutment teeth, a more wide and extensive platform what we so-called "frictional retentive facets". Accordingly we can afford to provide enough retention to our removable devices without exposing unaesthetic components such as vestibular retentive arms. Five clinical cases will be shown in order to sustain our proposal keeping in mind the need of respecting the right indication (AU)
