Abstract

LA INVENCION ESTA RELACIONADA CON UNA CAVIDAD COTILOIDEA ARTIFICIAL (16) ATORNILLABLE CON UNA ROSCA ESPECIAL (22-26) PARA SU IMPLANTACION EN EL SER HUMANO. LAS CAVIDADES COTILOIDEAS DE ESTE TIPO PRESENTAN NORMALMENTE UNA ROSCA PLANA CON FLANCOS DENTADOS PARALELOS O UNA ROSCA TRIANGULAR CON POSICION NEUTRAL DE LOS DIENTES, SIENDO HABITUAL UN PASO CONSTANTE EN DIRECCION AXIAL. NO OBSTANTE, ESTOS MODELOS NO RESULTAN CONVENIENTES POR NO CONSIDERAR SUFICIENTEMENTE LAS FUERZAS QUE SE PRODUCEN TANTO EN EL PROCESO DE IMPLANTACION COMO DURANTE SU UTILIZACION PREVISTA Y POR CAUSAR UNA DESTRUCCION INNECESARIAMENTE IMPORTANTE DEL LECHO OSEO EN CASO DE UNA EXTRACCION EVENTUALMENTE NECESARIA. CON LA INVENCION SE PROPONE UNA OPTIMACION ESPECIFICA DE LA ROSCA DEL COTILO (22-26), EMPLEANDOSE EL PERFIL DE ROSCA, LA POSICION ANGULAR DEL DIENTE DE ROSCA (22-26) Y UN PASO DE ROSCA NO LINEAL PARA GARANTIZAR UNA ATORNILLADURA CON MENOS FUERZA, UN ASIENTO FIRME PROLONGADO Y UNA EXTRACCION SIN PROBLEMAS.
