Description

DEVICE FOR IMPLANTS, FALSE LATCHES, SHUTTERS, STABILIZERS, IN DENTAL IMPLANTOLOGY

FIELD OF APPLICATION OF THE INVENTION The present invention relates to the field of dental implantology relates to a mechanical process for maintaining, fixing, tightening, stabilizing, balancing, allowing the different operations of this field of application to be carried out in the best conditions. conditions. DESCRIPTION OF THE PRIOR ART

The Applicant found that the implants were subjected to pressure and heavy constraints, overloads, discharges that disturb and endanger the result acquired.

Thus, for example, in the first place, it frequently appears once the implant is loaded, in the mouth undergoes untimely rotations, accidental, or still generated by the language of the patient.

Another aspect of the technological background with disadvantages noted by the applicant is at the level of the implant.

In fact, the implant is firstly placed in operation, placing the implant in the bone; it is left 6 months to obtain an osteo-integration is the bone that is deposited all around. In a second step, loading then, depending on the said implant, it becomes a carrier of a prosthesis. Depending on the case and many parameters, it often happens that it undergoes strong constraints, surcharges, discharges, pressure and very important rotations having an impact on its osseointegration which results in bone loss, and by the loss of the implant.

Another aspect of the technological background of the invention having drawbacks noted by the applicant. In the case of large litters, complete restoration up or down, the dental anatomy does not always allow the pose ideal pillars, that is to say implants. The average diameter of an implant is 3.75 mm. In large numbers it has a relative stability, but more consistent than when one has a limited number. In fact, poorly supported prostheses and bridges give way under pressure; the bridges being designed alloy with a significant thickness, give way despite those being poorly balanced, and especially by a lack of stability.

A prosthesis of this type is very expensive and generates a significant manufacturing time to be subjected again to the same disadvantages encountered but amplified by the fact of poor stability, a poor balance of forces.

The bridge, working in bad conditions, has transmitted to the pillars or some pillars such pressures that they come out often very weakened and this complicates the prosthetic future of the patient.

Another aspect of the technological background of the invention having drawbacks noted by the applicant is at the level of the implant itself. Indeed, because of the various screwing and unscrewing operations to which it is subjected well before the introduction of a false abutment and the installation of a prosthetic crown, it frequently happens that the screw breaks in the implant and makes the screw thread unusable, thus destroying all the work done up to now, and requiring complex extraction of the implant and in many cases making it impossible to put in place another implant.

Another aspect of the technological background with disadvantages noted by the applicant, the current screwing system is insufficient.

The stump rotates and has difficulty maintaining a prosthesis such as crown or bridge, in some cases it will destroy the crown, to have access to the screw again to perform a tightening, resulting in a considerable loss of time and significant impact on the implant that may be shaken. Another aspect of the technological background of the invention with disadvantages noted by the applicant is at the level of loss of the implant.

Indeed, it happens that the implants are placed in axes making impossible resistance to chewing, once equipped, and eventually give way to the neck of the implant, that is to say, from the implant, and carries a portion of the thread, which makes it impossible to install a prosthesis, thus annihilating all surgical and prosthetic work. This poses a big problem as to what to do next.

Another object of the invention is to propose a manufacturing method relating to a carrier stabilizing apparatus. This method has the advantage of having a central portion fixed in the bone and to provide great stability, protection screws, implants, etc..

Lateral anchors can move and come to the right place.

Another aspect of the technological background of the invention having disadvantages noted by the applicant, is at the level of the implant itself, its cylindrical shape, its diameter, its height in the mouth, it becomes vulnerable .

Another aspect of the technological background of the invention having disadvantages noted by the applicant, is at the angulation of the stump. The stump is the abutment that is screwed into the implant, there are stubs of 0, 10, 15, 25 degrees. One technique makes it possible to catch even more, beyond 30 and more.

Another aspect of the technological background of the invention with disadvantages noted by the applicant is that the shape of the implant is cylindrical, for the laying, many implants, all the relative breakthroughs others weaken the bone.

Another aspect of the technological background of the invention with disadvantages noted by the applicant is at the level of certain mouths of the bottom. - A - frequently happens that the mandible especially at the molar level offers areas not too important in bone density.

Another aspect of the technological background of the invention having drawbacks noted by the applicant is located at the screw transvissée which maintains the abutment, once in place, to protect the head and to access in case of unscrewing or maintenance, we close the square head.

At first, the practitioner will drown the head of the screw, by a dressing-type product commonly used in dentistry. Then he will position a layer of cotton to fill the hollow space. To complete this shutter, and to avoid infiltration, it will use the composite that is hardened using a lamp to photopolymerize. The material becomes very hard, it is then that the false stump becomes functional and will support the prostheses.

It is a screw with a diameter close to one millimeter, and having a square head. This screw is often rotated under the pressures and all the constraints to which it is subjected.

The practitioner is forced to intervene, and it is then that many disadvantages arise.

The screw embedded in the abutment covered with dental products, cotton, composite. To access it, it is necessary to destroy the composite, which is a product as hard as the tooth, using a strawberry used in dentistry, the practitioner will remove the composite, the cotton, as well as the product called gutta. Often, the stump suffers damage due to the cutter, it is the same for the head of the screw. The slightest damage caused by milling may compromise the screw forever given its small diameter.

During the lifetime of an implant in the mouth, the practitioner will be asked to proceed several times and each time of this kind. DESCRIPTION OF THE INVENTION On the basis of this fact, the applicant has conducted research aimed at overcoming the various disadvantages mentioned above.

According to another non-limiting embodiment, the applicant proposes a feature of the invention concerning the shutter FIG. 2f (13) having the particularity of nesting in force.

According to another non-limiting embodiment, the applicant proposes a feature of the invention concerning equipping the different types of stabilizer, multiple FIG. 1Oh (3), unitary stabilizer, fig. 10g (3). Another object of the invention is to provide the possibility of using a unitary stabilizer.

According to another non-limiting embodiment, the applicant proposes a feature of the invention concerning the stabilizer, FIG. 7g (3) multiple, or unit 8g (3), gives an incomparable base stump (12) Figure 8g and 7g being finally supported beyond their periphery. Our false stump will return to the original shape that is devolved to it in the traditional and non-implant prosthesis. Fig. 5g (64) for the top, (47) for the bottom, as examples.

Stubs in titanium alloy, will be designed in all known forms and with different angles.

According to another characteristic of the present invention and in order to improve its operation.

The transfer piece is a threaded piece of the type fig. Ig (18) extended downwards and provided with retentive parts on the inner part, on the outer part.

The transfer part is a key piece in the positioning of the implant.

The dentist must take an impression to send it to the laboratory, we will proceed as follows: once the implant in the jaw bone, will appear at the gum, the upper figure Ig (18) will be well visible parts (71), (54). The dentist will position the inlay-core (12) on the parts (54) and (55), (70) and (71), which will fit into one another.

The sliding ring will maintain and connect the parts (12) and (18), the dentist will take his imprint, once the impression taken, he will undo the ring (11) and recover the inlay-core (12) , a piece designed identically that (18) figure Ig will be screwed into the inlay-core (12) and once the set repositioned in the footprint, we will have a negative view.

In the laboratory the technician will fill the impression of plaster, once the latter has hardened, we undo the print, and we will have a very precise master model; hence the importance and name of the transfer room.

The latter may be made of metal, plastic, or any suitable alloy or material.

According to another characteristic of the present invention and in order to improve its operation another bad point adapted false stumps that puts dentists in very difficult situations.

The first operative time is the establishment of an implant. Six months after the loading is involved, that is to say make the implant with a false stump.

Implants are not always placed parallel to each other, because the anatomy does not always allow it.

In place, the false stumps will have to undergo retouches, to do this the dental practitioner, with the help of a fingerprint, will ask the prosthesis laboratory, to carry out this operation called "modification of the false stumps for purposes of parallelism" Frequently, during the return, during the act of disinfection, sterilization, and see accidentally, the stumps unfortunately mix, it is virtually impossible to find their original place.

We propose on our false stumps to strike them, that is to say to mark them with the number assigned to each tooth, arch of the top figure 5g (63) for the top of (17 to 11) and of (21 to 27 ). Fig. from the bottom 5g (63) for the bottom of "47 to 41" and "31 to 37"; which will have the effect of sterilizing, disinfect in an easier and risk-free way with increased comfort for the dentist practitioner, the prosthetist, but especially for the patient. According to another characteristic of the present invention and in order to improve the operation thereof in the prior art, it is possible to put in place, almost universally, two snaps, distributed at the level of the canines if the anatomy allows it; patients feel a lack of stability in fact the male part of the snap button being screwed into the implant; A ball with a diameter of 1 mm to 1.5 mm, or at least two balls is required. We imagine that two balls of the diameter mentioned can not fulfill their office in a satisfactory way to support a device of 14 teeth, complete prosthesis of the top or see complete prosthesis of the bottom. According to Figure 10g. our snap button has fastening means (70, 71, 54, 55, 13, 18, 11), plus an additional attachment adapted to this type of support, FIG. 10g, once the portion (55) in contact with the part (54), (71) with (70), the sliding ring (11) which has holes (81) will come into contact with the threaded holes of (80) and a screw will allow to fix them together and to prevent them from rotate. This assembly equipped on a structure called stabilizer, Figure 10g, represents (3) a unitary stabilizer equipped with a maxillofacial screw.

Figure 10h demonstrates the button (74) on a multiple stabilizer (3), this type of push button 1Oh the structure (73) can fit over our range, blade, double structure, etc. Figure Ic shows the stabilizer Figure Ic, (3) on site, the recommended technique being to equip two hemi-arches either up or down. It will be possible to have a remarkable support carrying snaps to appropriate areas; the canines on each side, as well as the molars, this type of architecture is amply enough to give the patient an unequaled comfort, stability, stabilizer.

It will be understood that the resulting implant obturator techniques, which have just been described and described above, have been in view of disclosure rather than limitation.

It is understood that the method for manufacturing a resulting implant prosthetic stabilization and support range, which have just been described and shown above, have been designed for disclosure rather than limitation; Of course, various arrangements, modifications, and improvements may be made to the example above, without departing from the scope of the invention taken in its aspects and its minds broader.
