Seguidamente se describen los tres sistemas A, B y C, que constituyen respectivamente el mejor, el intermedio y el peor de los sistemas para efectuar las funciones indicadas.The three systems A, B and C are described below, which constitute respectively the best, intermediate and worst systems to perform the indicated functions.
En primer lugar, se describe el primer sistema A, para la retirada del implante respecto del envase, transporte y colocación del implante directamente en la boca del paciente utilizando la llave, en relación a las figuras 1 a 5B, en las cuales se ilustra el conjunto compuesto por dichos implante -1- y su llave -23- que permite un acoplamiento elástico a modo de pinza del faldón -26- intermedio de la llave -23- en el cuello hexagonal -12- exterior coaxial al cono -11- interior circundante, que están previstos en la parte coronal -10- del implante -1-.

Este sistema C es el peor de los tres sistemas, porque las fuerzas de torsión se aplican más distantes de la punta autoroscante del implante en cuestión, pero también es muy válido. Thirdly, the third system C is described, of removal of the implant from the container, transport and placement of the implant directly in the patient's mouth using the key, illustrated in figures 11 to 16, which comprises the assembly consisting of said implant -3- and key -32-, which allows the coupling of the actuator tip -33- in a six-pointed star and of cylindrical sides with slight taper, in the upper end -34- of the stump -21-, previously fixed to the implant by means of the screw -22- cylindrical, whose end -34- of the stump is provided with the various six-pointed star cylindrical milling, with the cylindrical milled sides complementary, with those of the key, so that the torsional forces created in the placement of the implant-stump assembly -3, 21- in the bone bore are applied at the upper end of the stump -21- away from the self-tapping tip -16- of the implant, in whose coupling the slight taper of the star tip -33- of the key -32- allows the implant-stump assembly to be clamped away from the self-tapping tip -16- of the implant, and allows fastening by way of puncture of the implant-stump assembly to effect its removal from the container, its transport to the patient's mouth, and its placement directly in the hole of the bone of the mouth previously performed, after which the stump is removed -21 - of the implant -3- by unscrewing the clamping screw -22- for its subsequent cover, all this is done without external manipulation. This system C is the worst of the three systems, because the torsional forces are applied more distant from the self-tapping tip of the implant in question, but it is also very valid.
