     DENTAL IMPLANT DESCRIPTION 5 OBJECT OF THE INVENTION The present invention relates to a dental implant, the purpose of which is to achieve an implant of easier manufacturing and implantation, with the consequent lowering of 10 costs, and eliminating bacteriological flows causing certain diseases . BACKGROUND OF THE INVENTION 15 In a conventional implant the following elements participate: 20 25 • Body or implant proper, cylindrical, conical or mixed configuration, with an external surface threaded or provided with any type of surface irregularity that enhances its grip on the bone, and an axial, threaded and blind hole for receiving the screw that acts as a means of fixation for all implant elements. • A cover element or closing screw that, in a first phase of implantation, closes the aforementioned axial hole during the bone healing phase. • A healing abutment to form the gum in case the implant has been placed submerged. • A printing abutment that once placed on the implant, measures are taken in 30 silicone over the patient's mouth, which is sent to the laboratory to obtain replica models of the implant placed in the mouth as well as the corresponding crown of the implant, cemented crown or screwed ..5 10 15 20 25 • A final crown for the final implant. Its implantation is carried out in the following way: a) A bone accommodation is made for the implant itself and the implant body is inserted therein, the outer end of which is closed by means of the locking screw. b) If the implant is submerged, as is usually the majority, after the osseointegration time of the bone, the gum that covered the closure screw is opened during healing, this covering element is removed and replaced by the abutment cicatrization. c) Allowing approximately 15 days for gum healing, impressions of the implant with impression abutment are taken in an individual perforated tray if the implant is crammed with silicone impression material for shipment to the laboratory, where the crown of the implant. Two phases are previously established: -Proof of the metal structure. -Once it is valid it is sent back to the laboratory to place the porcelain. 30 The following problem derives from this structuring:• Phases a and b involve two interventions of a surgical nature, separated in time, with the consequent repercussion at the level of costs for the patient, discomfort and infections. 5 • In the prosthetic phase, two tests are carried out, first one of adjustment of metallic structure and later if everything goes well, placing the porcelain crown, which in turn supposes an important time consumption, as well as the assembly of certain prosthetic attachments. 10 • The tripartite nature of the whole body-pi lar-prosthesis generates passageways for 15 possible bacterial flows at a subgingival level that determine a shortening of the implant's useful life (perinplantitis, etc). • Possibility of rotating the crown during use, with possible fracture of the implant screw, in which case the implant would be completely unused. DESCRIPTION OF THE INVENTION 20 The implant that is recommended solves in a fully satisfactory way the problem previously exposed in each and every one of the aspects mentioned, determining an optimal barrier effect against possible bacterial migrations, and a substantial cost reduction based on a notable reduction both in the number of interventions to be performed and in the transfer of components between different places of work. To do this, and more specifically, the implant of the invention is constituted by a piece in which the implant and the abutment are integrated with a single piece, forming implant and abutment a certain angulation in certain cases, selectable from a suitable range of original parts, and only sometimes the abutment will need small adjustments of carving in some cases, at the end of the osseointegration process, to adapt the configuration and dimensions of said abutment to the antagonizing dental pieces,subsequently, after one or two months, depending on the case, the crown will be fixed to the implant abutment easily by means of the corresponding fixation screw or by cementation. More specifically, the main body or implant will be obtained in titanium, 5 the classic thread for its implantation in the bone being defined in the implant zone itself, while the part of the abutment could be of any other metal, with the particularity that between the area defined between the implant and the abutment a kind of perimeter skirt is established, in the form of an inverted cone trunk, with a smooth surface, which in the implantation maneuvers is arranged in the emergency area of the gingiva, an element that allows the anatomical adaptation of the gingival edge to the neck of the implant abutment, from the first moment of implant placement, facilitating healing and preventing the flow through this critical area of bacteria to the subgingival area. 15 This element not only serves that purpose, but also serves as a seating element for the inner crown shirt. As for the pillar itself, it will have a threaded central hole, for screw fixing of the corresponding crown, which does not have a circular plant, 20 fitting tightly on it and therefore making it impossible for the crown to rotate during use , thus guaranteeing its total immobilization. As for the crown, it is obtained from a shirt of a metallic nature covered by porcelain, formally and dimensionally appropriate to the abutment to which it fits by plugging, being able to be fixed by cementation or, preferably by screwing. The metal crown incorporates a simulative coating of the dental piece to be replaced, so that the vestibular, linguar, mesial and distal palatal faces are porcelain, while the upper or occlusal face is obtained in composite or acrylic, since the crown Metal on its occlusal face is concave to accommodate the composite made in the laboratory or performed in a clinic, with the corresponding hole for the screw fixing to the abutment, which will be protected with a sheet of textile covering, cotton or similar,before being covered with composite, to be able to later access said screw head in case it was necessary to disassemble the crown. This different nature of the occlusal face makes the implant have better mechanical characteristics from the occlusion point, ideal for combating bruxism, achieving a cushioning effect of occlusal efforts without damaging the implant. Also the occlusal face can be made of porcelain and the screw inlet hole sealed by composite in the traditional way. From this structuring, a structurally simple, economical implant is obtained, which minimizes the number of interventions necessary in the implantology process, facilitating the taking of impressions, not requiring individual cuvettes, impression pillars, replicas, prosthetic attachments and the like. , which results in greater comfort for both the patient and the dentist, as well as the corresponding cost reduction that this entails. DESCRIPTION OF THE DRAWINGS 20 To complement the description that will then be made and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, it is accompanied as an integral part of said description. , a set of planes where, for illustrative and non-limiting purposes, the following has been represented: Figure 1.- Shows a front elevation view of a dental implant made in accordance with the object of the present invention, devoid of the corresponding crown that is intended to be fixed to it by screwing. 30 Figure 2.- Shows a view of the device of the previous figure duly implanted in the bone and with the crown arranged on the corresponding pillar. Figure 3.- Shows a view in diametral and exploding section of the assembly of theimplant. Figure 4.- It shows a plan view of the assembly represented in figure 1. 5 Figure 5.- It shows a view similar to that of figure 3 but in which the assembly appears properly assembled. PREFERRED EMBODIMENT OF THE INVENTION In view of the figures described, and especially in Figure 1, it can be seen how the implant that is recommended is constituted from a main body (1), obtained from titanium, which has a single-piece character, and in which an implant zone (2) of titanium itself and a pillar (3) are defined, so that the latter may have different angles obtained from the factory, according to a range of products, 15 in function of the dental piece and special characteristics of the patient in question. The implant zone (2), of essentially cone-shaped configuration, is provided with the corresponding thread (4), for fixing the implant to the bone and microgranulated to have a greater osseointegration surface, with the particularity that in the area of 20 confluence between the implant zone (2) and the abutment (3) a perimeter skirt (5) is established, in the form of an inverted cone trunk, with a smooth surface, and that in the implantation maneuvers is arranged in the area emergency gum, allowing the anatomical adaptation of the gingival edge to the neck of the implant abutment, facilitating healing from the first moment of implant placement and preventing the flow of 25 bacteria to the subgingival area. This element also acts as a seat for the crown. On the other hand, the abutment (3) which, as stated above may have different angles or be aligned with respect to the axis of symmetry of the implant area (2), as can be seen in Figure 3, It has a central cylindrical hole (6), the base of which extends into a threaded hole (7). Said crown (9), the one shown in detail in Figure 4, has a metal shirt (16)5 formally and dimensionally suitable to connect tightly to the abutment (3), so that in it a neck or chimney (10) is defined to be engaged in the central hole (6) of the abutment (3), so that at presenting said pillar a circular plan thus prevents accidental rotation of said crown with respect to the pillar (3). For its immobilization and fixing to said pillar, the neck (10) will be finished in a lower hole (12) through which the fixing screw (11) is passed, which will in turn thread into the threaded hole (7) of the pillar (3). 10 As previously mentioned, this metallic shirt or crown (10) is covered by its lateral faces (13), specifically its vestibular, lingual, mesial and distal palatine faces, while the upper or occlusal face (14) is obtained in composite or acrylic, it is another optional modality especially in bruxist patients, with the corresponding hole (15) for passage of the fixing screw to the abutment. 15 In order to seal the hole (15) and not damage the screw head (11) it is provided that before applying a composite layer (16) on said hole, the screw head is protected with a cotton or textile element or similar (17). 20 Optionally, the crown could be fixed to the abutment by cementing, as previously mentioned, in which case all the anchoring attachments of the crown to the single-piece implant, screws, chimney would be eliminated for the manufacture of this single-piece implant. , threaded hole, etc., leaving the hermetic single-piece implant without screws and would be cemented on the implant abutment after printing a porcelain crown cemented in the traditional style.
