dental implant and prosthetic abutments system connected to the implant by a mechanical spring unscrewed. # The present invention provides a dental implant that provides rotary connection and a rotationally attachment thereon. The implant has at its upper end an opening for receiving said attachment having a first conical upper housing, followed by a section of polygonal cross section and finally a second lower conical housing. Thus, the first housing provides a rotary connection with an attachment whose lower end is conically corresponding to the first housing. Meanwhile, the second housing provides an attachment rotationally connected to the lower end has a portion of polygonal cross-section corresponding to the section of polygonal cross section of the dental implant followed by a lower conical end corresponding to the second housing. In addition, each of the first housing and the second housing has a step, so that the introduction of a lower end of the corresponding attachment is allowed and involuntary removal thereof is prevented once introduced.Implante dental y sistema de aditamentos protéticos con conexión a dicho implante mediante un resorte mecánico sin atornillar. La presente invención da a conocer un implante dental que proporciona conexión rotatoria y antirrotatoria de un aditamento sobre el mismo. El implante tiene en su extremo superior un orificio para la recepción de dicho aditamento que presenta un primer alojamiento superior cónico, seguido por un tramo de sección transversal poligonal y finalmente por un segundo alojamiento inferior cónico. Así, el primer alojamiento proporciona una conexión rotatoria con un aditamento cuyo extremo inferior es de forma cónica correspondiente al primer alojamiento. Por su parte, el segundo alojamiento proporciona una conexión antirrotatoria con un aditamento cuyo extremo inferior presenta un tramo de sección transversal poligonal correspondiente al tramo de sección transversal poligonal del implante dental seguid
