OROANTRAL PROSTHETIC ATTACHMENT

Abstract

An Oroantral Prosthetic Attachment placed in the remaining bone to anchor in the antral zone of the paranasal sinuses using the internal cortical of the paranasal sinuses and the external cortical of the crestal zone is described. This makes the implant not to migrate to the paranasal sinuses since a supreme anchorage is performed compacting the bone with no injury, and avoids previous bone regeneration surgeries in the paranasal sinuses.

Claims

1. An oroantral prosthetic attachment adapted to be inserted in a remaining bone to anchor in an antral zone of a paranasal sinuses of a patient, the oroantral prosthetic attachment comprising: a first cylindrical body having a flat tip and is provided with a first millimetric thread in an upper part followed by a widening, continuing with a second millimetric thread, and at a lower end a cubic body with vertical and horizontal markings; an anchor provided with a hole assembled or threaded into the first cylindrical body, and having inside a hole with a third millimetric thread and a thread stop for the first cylindrical body to stop; a clamping nut to fasten and obtain a supreme anchorage to the remaining bone, the clamping nut is assembled on the first millimetric thread of the first cylindrical body; a plug screw and a truncated cone or cap; the plug screw has a cavity at a top and a threaded body, the truncated cone or cap having a hole which is assembled with the first plug screw and an inside of the truncated cone is provided with a thread to accommodate a threaded part of clamping screw; the truncated cone or cap is assembled on the lower end of the clamping screw where it has a millimetric thread, and the cubic body with markings appears.

2. The oroantral prosthetic attachment according to claim 1, wherein the anchorage is done uniform and controlled causing a supreme anchorage to the remnant bone avoiding the implant to migrate to the paranasal sinuses and avoiding previous bone regeneration surgeries in the paranasal sinuses.

PREFERRED EMBODIMENT OF THE INVENTION

[0024] This invention is described based on a preferred embodiment of the Oroantral Prosthetic Attachment in which:

[0025] It is to be understood that the invention is not limited in its application to the construction details and component arrangement set forth in the accommodation presentation and illustrated in the drawings.

[0026] It is noted, unless otherwise provided, that all technical or scientific terms used herein have the same meaning as commonly held by persons having knowledge of the arts of the invention. The methods and examples provided herein are illustrative and are not intended to be limiting.

Preferred Embodiment

[0027] As can be seen in the Figures, the Oroantral Prosthetic Attachment is made up of the following elements; the clamping screw (1), the anchor (2), the clamping nut (3), plug screw (4) and the truncated cone (5).

[0028] The Oroantral Prosthetic Attachment is placed in the remaining bone to anchor in the antral zone of the paranasal sinuses using the internal cortical of the paranasal sinuses and the external cortical of the crestal zone. This makes the implant not to migrate to the paranasal sinuses and the saving of previous bone regeneration surgeries in the paranasal sinuses.

[0029] Each one of the constituent elements of the Oroantral Prosthetic Attachment is illustrated in one or more of the figures of the drawings and will be described in the following.

[0030] In relation to FIG. 1, the implant or prosthetic attachment of the invention is formed by a first cylindrical body, the clamping screw (1) with a flat tip, and the body of the prosthetic attachment of the invention is provided with a millimetric thread in the upper part where the anchor (2) is assembled or screwed, then a widening that will serve for the protection of the external cortical of the crestal zone continuing with millimetric thread appears, then in the inferior end a cubic body with laser-marked vertical and horizontal markings that help to the proper placement of the Oroantral Prosthetic Attachment appears.

[0031] In relation to FIG. 2, it shows the implant or prosthetic attachment of the invention which is formed by a cylindrical body, the clamping screw (1) with a flat tip and provided with a millimetric thread in the upper part followed by a widening that will serve for the protection of the external cortical of the crestal zone continuing with millimetric thread, and finally in the inferior end a cubic body with laser-marked vertical and horizontal markings that help to the proper placement of the Oroantral Prosthetic Attachment appears.

[0032] Regarding FIG. 3, it shows the anchor (2) which is provided with a hole that is assembled or threaded into the first cylindrical body, the anchor is provided inside the hole with a millimetric thread, and has a thread stop for the first cylindrical body to stop.

[0033] In relation to FIG. 4, it shows the clamping nut (3) which works to fasten and obtain a supreme anchorage to the bone, which is assembled on the millimetric thread of the first cylindrical body, i.e. the clamping screw (1), then the widening that will serve for the protection of the external cortical of the crestal area.

[0034] In relation to FIG. 5, the plug screw (4) and the truncated cone (5) are shown; the plug screw (4) has a cavity at the top and a threaded body, the truncated cone (5) or cap is provided with a hole which is assembled with the first plug screw (4), the truncated cone inside (5) is provided with a thread (not shown) capable of accommodating a threaded part of the first cylindrical body, i.e. of the clamping screw. The truncated cone (5) or cap is assembled on the lower end of the clamping screw (1) where it has a millimetric thread, and the cubic body with markings appears.
