Description

 IMPLANTOLOGICAL PLATE AND MANUFACTURING PROCEDURE OF THE SAME

Field of the invention

 The invention relates to an impiantoiotic piaca applicable in cases where there is not enough bone for a conventional implant. A case of application of the invention is that of upper maxillary atrophy without sufficient monopianar bone for impiantology.

State of the art

 When a person has lost their teeth in their entirety, formerly removable resin prostheses were made that were made through a mold of the mouth.

Dental implants (titanium screws of different alloys, shapes, sizes and surface treatments), revolutionized the way to treat patients who had lost all their teeth: implants were placed to incorporate screwed or cemented fixed teeth or to incorporate prostheses removable anchored to the implants so that the prosthesis was not so unstable.

The problem came when the patient did not have enough bone mass to accommodate and fix the implants. The implants have a minimum height and a minimum width; If the patient has less bone than is necessary for the dimensions of the implant, it is not feasible to apply this technique.

Given this situation where there is not enough bone in the upper jaw, alternatives have been sought, for example, to perform grafts (of the hip, shell, chin) or look for the zygomatic process of the cheekbone. The problem with these techniques is that they are of complex resolution, as well as aggressive for the patient.

An alternative to the techniques mentioned above is the fixation of plates, which can be made of titanium, either introduced vertically after cutting the jaws or fixed with small screws of very short length 3-4mm, but which have several points of support provide An anchor enough. These plates, however, have the problem that a post comes out of the bone without the ability to correct height or inclination. In addition, with these plates only cemented can be used, which increases the risk of fracture or inflammation. On the other hand, the plate is modeled manually, which causes a distortion of the material to be deformed to adapt it to the location where the implant will be placed, which increases the probability of fracturing the plate itself. i Description of the invention

 The invention solves these problems present so far in the state of the art. A basic embodiment of the invention is defined in claims 1 and 15. The dependent claims define additional features of the invention.

The implantological plate of the invention has a number of advantages over known proposals:

 1) The dimensions and geometry of the implantological plate are defined through a 3D Computerized Axial Tomography (CT) of 1/1 scale. Therefore the implantological plate does not require manipulation or torsion to adapt it to the housing where it will be anchored, so its structural properties are not altered. By following the exact form of the patient's physiognomy, the surgery is very simple to perform. Through a CT scan, the shape of the implantological plate is determined to take advantage of the three-dimensionally available bone. Thus, the implantological plate of the invention gives a solution to those cases of bone atrophy of the upper jaw that do not have enough bone to be able to place the implants in a conventional manner.

2) The implantological plate of the invention can have an external anchor in the form of a hexagon like the most commonly used implant: in this way, once the implantological plate of the invention has been fixed, it can be used to apply the same prosthetic attachments and conventional implant solutions. That is, the implantological plate of the invention is compatible with implants or prostheses commonly used or using the connection considered universal.

3) The hexagon-shaped external anchor allows you to screw dental structures and, using transepithelial abutments, also called MultiUnits Abutment (MUAs), the depth and angulation of the implant can be corrected, something essential for making screwed teeth. On the contrary, the known plates do not allow to change the depth or the angulation.

4) The implantological plate of the invention, in order to avoid cementation, also prevents the consequent contamination. On the other hand, as the teeth can be easily disassembled by means of screws, the biomechanical risks of breakage are reduced. Thus, if it is necessary to correct the implant, the implantological plate of the invention allows corrections or modifications to be carried out by unscrewing and screwing operations. that is, adjustments can be made without breaking the implant.

Therefore, the implant plate of the invention, and the method of manufacturing it, are key innovations in the way to treat the maxillary atrophy of the upper jaw, since they allow to avoid large surgeries and rescue patients with little bone available for an implant .

Detailed description of the invention

An embodiment of the invention relates to an implant plate (110), which can be made of titanium, configured to take advantage of the upper jaw bone in three dimensions. This implant plate (110) comprises an external hexagon that allows screwing the dental prosthetic structures that are required; that is, once the implantological plate (110) is anchored, an external connection of the same benefit is achieved as a conventional implant, The implantological piaca (1 10) of the invention is indicated in those cases of maxillary atrophy without bone sufficient to place conventional implants in the monoplanar bone, but with enough three-dimensional bone to put the implantological plate (110).

To make the implant plate (110) of the invention:

1) A 1/1 scale CT scan of the patient's maxilla is performed.

2) From that scanner, the implantological piaca (1 10) is designed based on the shape of that maxilla. This implantological piaca (110) is individualized for each patient in terms of size and shape, but always following a pattern according to predetermined conditions.

An advantage of the implantological piaca (110) of the invention is that, once placed, the same connection as a conventional implant is available, and the same dental rehabilitation protocols can be applied. Implant plates (110) can also be joined with other plates or with other implants, allowing a whole dental arch to be screwed to the patient being treated.
