Abstract
The invention discloses an integrated 3 D surgical guide, guide bar, mini-implant system and a procedure to stabilize dental prostheses, based on implanting two parallel mini-implants at a given distance and then joining them by means of a prosthetic bar mounted on them, thus achieving the required strength to mount on the bar a metallic clip that retains a dental prosthesis. The advantage of this integrated system is the stabilization of dental prostheses with high precision and save standardized protocol, lower costs and less trauma for the patient than the traditionally used method.
Claims6
An integrated system to stabilize dental prostheses, said integrated system comprising a 3 D surgical guide, a guide bar, an implant holder, two mini-implants and a prosthetic bar, wherein said 3 D surgical guide is Y-shaped in top and bottom plan views, its arms having two extensions at their bottom ends that have different heights, with two inwardly positioned nails, and having at the top end of one of the arms a cylinder with a diameter of 3 mm departing 1 mm inwardly from said arm, said cylinder having a central hole with a diameter of 1 mm and a bar departing from its side in parallel relationship with the arm, said bar having an end cylinder with a trunk-conical perforation inside.
A 3 D surgical guide to center bone perforations when a dental prosthesis is installed, wherein said 3 D surgical guide is Y-shaped in top and bottom plan views, its arms having two extensions at their bottom ends that have different heights, with two inwardly positioned nails, and having at the top end of one of the arms a cylinder with a diameter of 3 mm departing 1 mm inwardly from said arm, said cylinder having a central hole with a diameter of 1 mm and a bar departing from its side in parallel relationship with the arm, said bar having an end cylinder with a trunk-conical perforation inside.
