    Double dental implant stable against periimplantitis. It is constituted from an implant formed by two implants: upper implant (1) and lower implant (2), being able to remove the superior implant (1) differentiating itself from the classic implant in having a second polished band (7) in the body of the implant (1, 2), which corresponds to the start of the lower implant (2) and comprises a connection between the two implants (1, 2) by means of a screw (8) which is located in the lower part of the upper implant (1). ) and of which it forms part, staying in the thread (9) of the inferior implant (2). The connection between both (1, 2) is circular, since it has to allow to rotate counterclockwise when it is removed. (Machine-translation by Google Translate, not legally binding)

     DOUBLE DENTAL IMPLANT STABLE AGAINST PERIIMPLANTITIS OBJECT OF THE INVENTION The present invention relates to a double dental implant (upper / lower) characteristic because it is stable against Periimplantitis avoiding its treatment and / or consequences of losing the implant, and also useful in aesthetic and prosthetic complications. Currently, the implant logic techniques are widely extended and allow replacing missing teeth with implants, where the implant would have the same function as the tooth root. The corresponding dental prosthesis is attached to the implant. Phases: This technique of dental rehabilitation is generally summarized in two initial phase of surgery, where the implants that will be the fixations for the dentures or dental pieces that need to be replaced are placed. Second phase, where measurements are taken from the patient's mouth to make and then place the prosthesis on the implants. Looking to return the functions of lost pieces (chewing, aesthetics, ...). 20 One of the factors that most influences the success of the implant is the balance between microorganisms in the mouth and the patient's defenses. When this balance is broken, periodontitis with bone loss that surrounds the root can result in teeth and in implants, periimplantitis with bone loss that surrounds the implant. 25 The treatment of periimplantitis is today a problem with unpredictable results. This is mainly due to the difficulty of accessing the contaminated area of the implant, its turns, the surface of the implant that has been previously treated with micro-roughnesses to favor osseointegration.of the implant in the bone, but difficult to clean, decontaminate and polish when contaminated by microorganisms and their detritus. So the treatments are many and varied, but of little success, reaching in many cases the loss of the implant. S This invention would be ideal for these cases of periimplantatitis in which the loss of bone around the implant only affects the upper implant, the second (lower) implant being able to remain, with the same characteristics as the double implant but shorter. In this situation we remove the contaminated part (upper implant), 10 leaving another implant (lower implant) in the same position and connection without having to do a new surgery to place another new implant, which is also usually accompanied by bone grafting, with the subsequent new prosthesis, after the waiting time for the integration of this implant. Another advantage is that in addition to leaving the lower implant that remains integrated in the bone, it is to be able to leave the prosthesis that the patient has, if we replace the upper implant with a transepithelial abutment of the same height and connection of the implant that we have removed. To this we must add the situation that is achieved with the transepithelial abutment that has a smooth and polished surface, which is what is sought in 20 treatments of periimplantitis. Another complication that we can solve is of an aesthetic nature, a situation that can be contemplated when an implant has titanium turns seen or becomes transparent through the gum. One might consider replacing the upper implant with a transepithelial abutment with white or pink 2S porcelain coating. In the case of prosthetic complications, there are situations where the screw that holds the prosthesis is broken and cannot be rescued, leaving an unusable implant; this would be solved by removing the upper implant with the broken screw and placing either a new upper implant or another transepithelial abutment 30 of the measure of the upper implantAnother advantage of the double implant would be the possibility of recognizing it on an x-ray by visualizing a second polished band on the implant body. The industrial application of this invention is within sector 5 of dental surgery and more specifically dental implants. BACKGROUND OF THE INVENTION Although no invention has been found identical to that described, we present below the documents found that reflect the state of the art related to it. 10 Thus, document ES2281995A1 refers to improvements introduced in dental implants, specifically in relation to the distribution of surface types in contact with the bone for osseointegration (hydroxyapatite coating or rough finish), in titanium-based cylindrical implants or titanium alloys, presenting a polished area 15 or neck (2) emerging from the maxilla and occupying the order of 1.5 to 2 mm, in which the prosthetic part of the implant is inserted, and the remaining area being treated its surface for to obtain the desired surface finish, that the surface treatment consists in performing a hydroxyapatite coating (4) in the first phase, leaving a band or zone (8) free of the implant of the order of 4 ± 2 mm after the polished neck (2 ), which will then be subjected to rough treatment (3) by conventionally immersing it in acids and sandblasting with different substances. At no time is the double implant solution proposed by the main invention mentioned. ES1025017U proposes a dental implant, which comprises a cylindrical body of titanium defined by: an upper area of greater diameter; an intermediate zone and an apical lower zone; the upper area called coronal is divided into three sections, one threaded, another that defines a perimeter groove and the end that is frustoconical; the intermediate zone consists of an external threaded portion, and another portion of smaller diameter with recesses 30 which are occupied by neoformed bone; the apical lower zone is conical or pyramidal with regularly arranged recesses that are complements forensure implant anti-rotation; and because between the extreme threaded portion and the smaller diameter portion both of the intermediate zone, there are drilled holes in communication with the bottom of an axial blind hole having an internal threaded area as an extension 5 of a widening of the area bore upper in which the tooth popup is attached. As in the previous case, the solution of the implant executed in two, upper and lower, is not mentioned. ES2363046T3 describes an implant with anti-inflammatory or antibacterial effects, or both, the implant being intended for implantation in the human body or in the body of an animal, the implant comprising a set of porous grains or granules in which the porous grains or granules - they comprise titanium, one or more titanium oxides or titanium alloys and have a layer of tyranium oxide on their surfaces; -They have an average length from one side to the opposite side, through a geometric center 15, from 200 IJm and up to 5 mm: -They have an average specific surface area of at least O, 15 m2 / g according to the BET method. The implant solution does not again comprise two parts as the main invention. Thus ES2555827 A 1 Refers to a procedure for the application of antibacterial protection in a dental implant; said implant comprising at least one outer surface formed in titanium or a titanium alloy; characterized in that it comprises: a) a previous preparation of the external surface of the implant; including at least one of the following operations: roughing, polishing, cleaning, decontamination and / or removal of a layer of titanium oxide from said external surface of the implant, and b) the deposit of silver particles on an external surface of the implant, of titanium or a titanium alloy, by means of a pulsed electrochemical anodization process. Again, it is not based on the division of the implant into two superimposed implants as proposed by the main invention. ES2432416T3 proposes a dental implant for anchoring dental prostheses 30, with a coating (6) of zirconium nitride (ZrN) with a layer thickness of 1 to 10 IJm. Nor does it mention the application of a double implant.ES2392582T3 describes a cylindrical dental implant based on titanium or titanium alloys, which has a polished area or emerging neck of the implant and occupies an area of the order of 1, 5 to 2 mm, in which the neck of the false tooth of the implant it is adapted to be inserted, and the remaining area 5 has its surface treated, the implant comprises a hydroxyapatite coating leaving a band or zone of the implant of the order of 4 + 2 mm free after the polished neck and said band or zone having a rough surface achieved by treatment after subjecting it to acids and sandblasting. The proposed solution does not include the implant divided into two superimposed implants as proposed by the main invention. Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised as the proposed invention does. DESCRIPTION OF THE INVENTION 15 The stable double dental implant against periimplantitis object of the present invention is constituted from an implant formed by two implants: upper implant and lower implant, the upper implant being able to be removed. The double implant only differs externally from the classic implant 20 in having a second polished band in the implant body, which corresponds to the start of the lower implant. The connection between the two implants is by means of a screw that is located in the lower part of the upper implant and of which it forms part, being lodged in the thread of the lower implant. 25 The connection between the two is circular, since it has to allow it to rotate counterclockwise when removed.

Thread CONNECTION DESCRIPTION OF A PREFERRED EMBODIMENT A preferred embodiment of the stable double dental implant against periimplantitis object of the present invention, with reference to the numerical references, can be based on an implant formed by two implants: upper implant (1) and lower implant (2), being able to remove the upper implant (1). As for morphology and connection, it includes those of the classic implant: cylindrical morphology, in self-tapping turns (3) with narrower apex, with connection to external hexagon (4) of 2.70 mm, height of hexagon (5) of 0.70 mm and connection platform (6) of 4.10 mm. The diameter of the implant (1, 25 2) is 4.10 mm and the height 11.5 mm. The double implant (1, 2) only differs externally from the classic implant in having a second polished band (7) in the implant body (1, 2), which corresponds to the start of the lower implant (2).The connection between the two implants (1,2) is by means of a screw (8) that is located in the lower part of the upper implant (1) and of which it forms part, being housed in the thread (9) of the lower implant ( 2). The connection between the two (1, 2) is circular, since it has to be allowed to rotate counterclockwise when removed.
