    Dual fixation system for prostheses on dental implants consisting of: a set of intermediate fixation abutment on the implant (FIG 6), clip fastening device (FIG 3), fixation screw (FIG 4) and cylinder (FIG 1) that allows the prosthesis to be screwed or retained by clip as appropriate, individually and independently for each implant. This system facilitates both the immediate loading technique and the execution of the final prostheses performed on the intermediate abutment, since clip retention is very advantageous in the case of implants with unfavorable emergencies, joining them to the structure as pillars and without compromising the aesthetics of the implant. case.

     DESCRIPTION DUAL FIXING SYSTEM FOR PROSTHESIS ON DENTAL IMPLANTS THAT ALLOWS THE PROSTHESIS TO BE SCREWED OR RETAINED BY CLIP AS CONVENTIONED TECHNICAL SECTOR The present invention relates to a prosthetic device that goes over a pillar of a dental implant. Enter the oral implantology sector. BACKGROUND OF THE INVENTION Immediate loading processes are increasingly common in current implantology practice. Patients frequently demand to leave the consultation with a transient prosthesis supported by the implants that have just been placed. The usual retention systems for this type of prosthesis are currently two: - Cementing technique on the direct implant abutment. -Screwing technique on intermediate pillar through the crown. The present invention opens a new path, that of clip retention, because the new cylinder can be screwed from above but also retained by clip from below. If it is a question of restoring unit crowns, the best system is cement-screwing directly to the implant, without intermediate abutment. That is, the crown is cemented on a pillar screwed directly to the implant and then, by drilling it by lingual, the screw is accessed. Then it is released, adapted, retouched, polished and replaced exclusively screwed. In this way we guarantee the passive adjustment. But in the case of multiple implants, this is a bit more complicated, and usually works with prostheses screwed on intermediate pillars, whose titanium cylinders are splinted intraorally, with titanium bars, to avoid implant movements and reinforce the structure of the prosthesis, usually resin. In Immediate Load processes (implants are not yet osseointegrated) it is---------------- sufficiently described in the literature the fact that there should be no micromotion of implants that go beyond 150 microns if we do not want to compromise osseointegration. The simplest and most reliable technique to avoid these movements is to join the implants as rigidly as possible, by welding intraorally, with small titanium bars, the cylinders screwed on the intermediate abutments. These titanium bars are fused with the cylinders by means of a very localized and totally safe electrical process for the patient and the professional (synchronization). This technique of joining the cylinders with welded titanium is not strictly necessary, but highly recommended, especially if we are making immediate loading and if the distance between the implants is important, to avoid micromovements, and minimize the loads around the emergence of the implant, contributing to the maturation and conformation of the soft tissues and the adjacent bone. In the event that the implants are joined only by resin, more flexible, there will be greater possibility of micromotions that affect the implants, and also on the other hand there will be a greater probability of fracture and consequent failure of the entire immediate loading system. Once the ferulized titanium bar with the built-in cylinders is obtained, these are screwed onto the intermediate pillars, the chimneys are covered with silicone or Teflon, and then the prefabricated resin prosthesis that has been previously recessed so that the titanium bar is placed I can get into it. Here we have two options: 1. Long Cylinders Technique: It consists of making the chimneys of the cylinders emerge through the prosthesis so that we can access the screws and release it. This technique has the disadvantage that the perforation of the prosthesis has to be done in a very approximate way, by eye, with which the destruction will be important, and often the titanium tubes of the emerging cylinders will compromise the aesthetics. 2. Short Cylinders Technique: The cylinders are covered by resin, they do not emerge and we will be obliged to look for the chimneys to access the screws and release the prosthesis. This second technique is very easy when it comes to short bridges, but very complicated in complete arcades, since the divergence of the implants makes it not easy to look for the chimneys corresponding to each of them. The invention solves this problem and greatly facilitates immediate loading processes in multiple cases, thanks to the cylinder assembly and the clip fixing device.5 ------------ need to screw or cement, as detailed in the explanation of the invention. EXPLANATION OF THE INVENTION The present invention opens a new way in the techniques of performing prostheses on dental implants: the retention of the prosthesis by clip on an intermediate abutment, 10 converting the intermediate abutment into a retention abutment, since the New cylinder presenting the invention can be screwed from above but also retained by clip from below. The invention considerably facilitates and improves current immediate loading procedures in multiple cases, thanks to the cylinder assembly and the clip fixing device, and also serves to retain complete arch structures without the need to screw or cement. This is a huge advantage in both provisional and definitive prostheses, since it allows the patient to be able to remove, clean and replace it. It would be something like a fixed-removable prosthesis, that is, fixed prosthesis behavior 20 but that can be easily removed. This type of prosthesis is ideal in the transitional phase, until the patient is completely comfortable with it. Therefore, the same prosthesis can be screwed in a classic manner, or retained by friction-clip. Simply replace the screws with the invented device; This is valid for each of the cylinders that make up said prosthesis individually and independently. In this way, it is also possible to alternate screwed implant and clip retained implant, mixing screwed cylinders in the same structure with others retained by said clip device at convenience. Example: If we have an entire arch with six implants, three can be screwed and 30 can be retained by clip, precisely those with unfavorable emergencies that will normally be in the previous sector. Or four bolted and two retained by clip, etc. All combinations are possible, and all of them remain open in time. The invention allows to be used for resin prostheses but, thanks to a base of cemented cement whose internal characteristics with the same as the cylinder (coneconcavity), can also be used in fixed prostheses, e.g. Zirconium or ceramo-metallic structures. Another advantage of the invention is the possibility of taking prints with copings or transfers only retained by the clip (FIG 27), without being screwed in. In this way, 5 the measurement is facilitated since the placement in the mouth of the same ( per clip) is almost instantaneous and withdrawal, even easier. Also, the tray for this purpose will be closed, which greatly facilitates the task. The invention is a system composed of several parts: 10 1. A cylinder (FIG. 1 and 2) 15 2. A cement base (FIG. 5) . 3. A clip fixing device (FIG. 3). 4. A fixing screw (FIG. 4) 5. An intermediate fixing post on the implant (FIG. 6). Each piece is detailed below: 1.-The special cylinder (piece that goes over the intermediate pillar) (FIG. 1) has a double housing, which allows it to be screwed from above or retained by friction-clip from below. 20 This cylinder therefore has two different housings, one conical in its upper part (1 c) for the settlement of the conical fixing screw, and the other in its lower part in the form of a concave ring (1 b) where the convex ring of the clip fixing device. 2.-The cement base (FIG. 5) with the same characteristics mentioned above for the cylinder, has the same upper conical housings (1 c) in lower concave ring (1 b), and serves to replace the cylinder in the cases of zirconium or ceramo-metallic prostheses, and in their preferred and non-exclusive embodiment, have retention grooves for the cement (5 a). 3.-The clip fixing device (FIG. 3) consists of a convex ring in its upper part (3a) and a thread in the lower part (8b), with which it is screwed onto the intermediate pillar (FIG. 6 ), occupying the space that is normally destined for the fixing screw (FIG. 4) and which is used instead of it to retain the friction-clip prosthesis. The convexity of the clip fixing device (3a) is housed in the concavity of the cylinder (1 b) forming a concave convex ring. The head of the fixing device 35 by clip has inside the female footprint of the screwdriver (8a) that weIt can be screwed and unscrewed on the intermediate pillar (FIG. 8). 4.-The fixing screw (FIGA) has a seating cone (4a) that will be seated on the cylinder cone (1 c). 5.-The intermediate abutment that goes over the implant (FIG. 6) has an internal thread (6a) in 5 which houses the clip fixing device (FIG. 3), as well as the fixing screw (FIGA) . This abutment can be made at different heights depending on the gingival height with respect to the implant. This intermediate abutment has a female screwdriver footprint (6 b) with which it can be screwed through a thread (6d) onto the implant, generating friction on it thanks to the conical wall (6c). The great advantage of the system is that each cylinder or cement base of the prosthesis can be screwed or retained by clip, individually and independently, conveniently, within the same prosthesis, always keeping the two options. 15 For example, we will be able to screw the implants that have favorable emergencies and only leave those that do not meet these conditions retained by clip, and this temporarily or permanently. The cylinder can rotate 360 degrees around the clip fixing device, since it is a double concave-convex ring. This allows us to look for angled accesses 20 in case the axial access compromises the aesthetics of the dental prosthesis. In this preferred and non-exclusive embodiment, the fixing device can be manufactured in peek and its function is to retain the cylinders on the pillars without having to be screwed. The clip retention provided by the invention allows us, in the technique of short cylinders, to remove the protruding prosthesis from the mouth without having to search for chimneys, since it will only be retained by clip greatly facilitating the clinical process. 30 Once out of the mouth, with the prosthesis removed, finding the screw access chimneys is much easier, since it is enough to position the cylinders one by one on an analogue to which a clip fixing device has previously been threaded to visualize the shaft and mill accordingly to access the screw. Everything explained above for the cylinder is equally valid for the cemented base if the prostheses are made of zirconium or metal-ceramics.It should be noted that this retention system is valid for any type of implant system on the market, modifying the cylinders and, where appropriate, the abutments according to the design of the chosen implant. The novel conical settlement so marked with the screw (4a) on the cylinder or the cement base 5 (1 c), allows better distribution of stress related to prosthetic loads. This fact together with the friction provided by the two cones make the system much more stable in the long term, avoiding loosening. Another advantage of the invention consists in the possibility of making both the cylinder and the cement base in a short version, of reduced height (FIG. 23 AND FIG. 25) in which both only contain the circumferential concavity in the form of ring and the one relative to the cone is suppressed, making them shorter and closed at the top, as capsules, (FIG 23) Y (FIG 25). This eliminates the possibility of screwing and the system will only be clip fixing, but always using the clip fixing device 15 as the sole means of retention (FIGS. 24 and 26). This possibility is helpful in cases of low prosthetic height. 20 25 30 35 The external shapes of these capsules can be multiple, with a greater or lesser degree of convergence of the walls, according to the prosthetic functionality and the interior of them being always the same.

PREFERRED EMBODIMENT OF THE INVENTION In addition to what is already specified in the drawings and as detailed in the previous section 15 of the description as to the preferred and non-exclusive embodiment of the invention, various materials can be used to manufacture the system. The male device that is threaded in the intermediate pillar can be manufactured in Peek. This material gives it great abrasion resistance while providing the flexibility necessary for the clip effect. Also the material allows a high precision of 20 machining. Based on this precision of machining, and changing the tolerances, we can obtain different degrees of retention and for this purpose a color code indicating the degree of retention can be established. Another manufacturing alternative would be to make the male of the clip fixing device (FIG. 3) in titanium instead of peek, and consequently make the capsule in peek instead of titanium. Not being any of these possibilities or materials excluding others. 30 Both the cylinder and the cement base can be made of various materials, such as eg. titanium, gold-palladium, peek and equivalent, without these materials being exclusive or necessary for the realization of the invention.
