    DESCRIPTION
    "BIOFILM" COLLECTION ADDITION IN DENTAL IMPLANTS OBJECT OF THE INVENTION
    The invention, as expressed in the statement of the present specification, refers to a "biofilm" collector attachment in dental implants, which provides advantages and characteristics, which will be described in detail below, which represent a novelty in the state Current technique.
    More particularly, the object of the invention is centered on a removable attachment that, formed by a screw-on piece, simulates the external geometry of an implant whose purpose is to allow recovering an intact biofilm similar to that which would be formed on an implant exposed to the cavity oral, in order to facilitate studies on the etiology of peri-implant diseases and subsequent treatment.
    FIELD OF APPLICATION OF THE INVENTION
    The field of application of the present invention is part of the dentistry sector, focusing particularly on the field of industry dedicated to the manufacture of dental implantology elements.
    BACKGROUND OF THE INVENTION
    As is known, dental implants are one of the main therapeutic options to replace missing teeth. Although the survival and success rates of these devices are very high, biological complications, such as mucositis or peri-implantitis, are frequent. It is estimated that between 12 and 22% of patients with dental implants will be diagnosed with peri-implantitis after a short follow-up period (5 years).
    Peri-implantitis is considered a chronic infectious pathology, which begins with the formation of a heterogeneous biofilm. Previous studies have suggested that this disease

    It simulates the process that occurs in periodontitis, and that the bacteria that colonize the surface of the implants is similar to those found in teeth with periodontal pathology.
    However, recent findings suggest a new model of pathogenesis in which periodontitis begins with a widely dysbiotic and synergistic microbiota, which contradicts the traditional theory that this disease would be caused by one or a reduced number of pathogens.
    This can also occur in peri-implant diseases. The knowledge about the microbiota present in peri-implantitis is quite scarce and the differences between biofilms formed on healthy teeth and implants need further investigation. It is essential to know in depth the bacteria involved in periimplantitis to improve the results of current treatments.
    Some authors have studied the microbiota present around osseointegrated implants, however, in these studies samples have been collected through sterile paper tips, periodontal probes or curettes. These procedures allow recovering part of the bacteria present in the area, but it is unlikely that they can remove bacteria that are firmly attached to the implant.
    The analysis of the entire biofilm that is formed on exposed dental implants is of great interest from the point of view of the investigation of peri-implant diseases. However, this would only be possible through implant explantation, which raises very important ethical problems.
    Thus, the complete analysis of a biofilm could only be done in cases that require the removal of implants (usually with very advanced pathology). This is a very rare procedure, and therefore prevents the realization of in vivo studies with large samples in order to describe the biofilm formed on dental implants.
    The objective of the present invention is, therefore, to develop an attachment specifically designed to avoid said problem and to provide a practical and simple means of obtaining the biofilm of an implant under the conditions of the oral cavity, without the need for

    remove the implant, to allow studies on it much more effectively.
    On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of no other biofilm collector attachment in dental implants or any other similar application invention to be presented is unknown. technical, structural and constitutive characteristics equal to or similar to those presented here, as claimed.
    EXPLANATION OF THE INVENTION
    Thus, the "biofilm" collector attachment in dental implants that the invention proposes is configured as a remarkable novelty within its field of application, since according to its implementation the objectives previously indicated as suitable are satisfactorily achieved, the characterizing details being which distinguish it, conveniently set forth in the final claims that accompany this description thereof.
    More specifically, what the invention proposes, as noted above, is an attachment that can be screwed and unscrewed to an implant and that reproduces exactly the external geometry of the implant, the macro and micro roughness of the implant surface, in order to be able to remove said attachment later.
    Said surface and geometry of the attachment may or may not depend on the geometry and surface of the implant to which it is screwed.
    In any case, the attachment is configured as an element provided with at least one thread that is screwed to the implant and therefore through which it will share the same biofilm that the implant has attached.
    Once the estimated sufficient time has elapsed for said biofilm to also adhere to the attachment, which may take a few days or weeks, during which the patient will not notice any discomfort, the same will be removed by unscrewing it from the implant, after which, the biofilm can be analyzed externally, in its

    10

    totality, adhered to the surface of the attachment, in order to determine its nature and composition.
    The biological information obtained in said attachment will serve to increase knowledge about peri-implant biology or to decide treatments to apply based on the composition of the biofilm.
    Given the above, it is found that the described jumping device represents an innovative structure of structural and constitutive characteristics unknown until now for the purpose to which it is intended, reasons that together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity requested.

    PREFERRED EMBODIMENT OF THE INVENTION
    In view of the aforementioned figures, and according to the numbering adopted, an example of non-limiting realization of the "biofilm" collecting attachment in dental implants can be seen, which includes the parts and elements indicated and described in detail below.
    Thus, as observed in said figures, the attachment in question consists of a removable part (1) provided with a fixation zone (1a) to the implant, which preferably has a thread portion with a configuration suitable for tapping into the hole internal threading of the implant (2) to which it is intended, and a biofilm collection area (1b) that is located externally to the implant (2), once the removable part (1) is fixed thereto, and reproduces, exactly, the external geometry (2a) of the implant (2), normally a thread, including the macro and micro roughness of the surface of said external zone (2a) of the implant, in order to be able to collect the biofilm adhered to said collection zone ( 1b) by subsequently removing the attachment (1) in order to study its composition.
    For the placement and removal of the removable part (1) that constitutes the attachment, this account, in addition, with a mechanized hole (1c) in its upper part, for example of hexagonal configuration, suitable for the insertion of a bolting tool and unscrewed with a suitable complementary configuration.
    Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to extend its explanation so that any expert in the field understands its scope and the advantages that derive from it, stating that, within its essentiality, it may be carried out in other forms of realization that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is sought as long as it does not alter, change or modify its fundamental principle .
