Abstract

The present invention relates to a dental post (1) for supporting dental prostheses (2) by means of a screw attachment and method for the manufacture thereof which provides a customizable optimum solution for each case, both from the mechanical viewpoint and from the aesthetic viewpoint, essentially comprising an upper hole (8′) into which the retaining screw (4′) is screwed for retaining the prosthesis (2) on the post (1) such that the upper hole (8′) can be located at any point of the surface of the post once said post (1) has been customized in terms of the shape thereof and type of retention to the prosthesis (2) depending on the mechanical and aesthetic needs of the type of rehabilitation suitable for each particular case.

Claims

1. Dental post for supporting dental prostheses comprising at least one upper hole into which a retaining screw is screwed for fixing the prosthesis on the post, characterized in that said upper hole can be located at any point of the surface of the post once said post has been customized in terms of the shape thereof and type of retention to the prosthesis depending on the mechanical and aesthetic needs of the type of rehabilitation suitable for each particular case.

2. Method for the manufacture of a post for supporting dental prostheses comprising at least one upper hole into which a retaining screw is screwed for fixing the prosthesis on the post, characterized in that it comprises the steps of:

taking an impression of the patient'"'"'s mouth,

designing the post with the data of the patient obtained in the preceding step, customizing the shape thereof and type of retention to the prosthesis depending on the mechanical and aesthetic needs of the patient and calculating the ideal position of the upper hole by means of simulating the masticatory loads and the aesthetic requirements of the patient,

transferring the file with the information obtained from the preceding step of designing to the step of planning for the manufacture of the post; and

manufacturing the post itself.

3. Method for the manufacture of a post for supporting dental prostheses according to claim 2, characterized in that a computer-aided design or CAD software is used in the step of designing the post.

4. Method for the manufacture of a post for supporting dental prostheses according to claim 2, characterized in that the step of transferring the information obtained in the step of designing the post is performed by means of a computer-aided manufacturing or CAM software and in that the database which is developed during CAD is processed by CAM to obtain a file with the data and the instructions necessary for operating and controlling the manufacturing machinery, the material handling equipment and the automated tests and inspections for establishing product quality.

5. Method for the manufacture of a post for supporting dental prostheses according to claim 2, characterized in that for the final manufacture of the post a rapid prototyping method, high precision machining, sintering in furnace or electric discharge machining or combinations thereof is used such that they allow a maximum level of fitting between all the elements.

6. Method for the manufacture of a post for supporting dental prostheses according to claim 4, characterized in that for the final manufacture of the post a rapid prototyping method, high precision machining, sintering in furnace or electric discharge machining or combinations thereof is used such that they allow a maximum level of fitting between all the elements.
