SYSTEM OF TRIPLE TOOTH ABUTTERS WITH TCONNECT

Description

[0001] The present invention describes the System of Triple abutments with Tconnect, made with an innovative and exclusive design support, present in all the components of the system, with paraboloid multidimensional contour in double shape curvature, and three pins, disposed in the form of a tripod arrangement and that promotes optimization of the loading conditions, contributes for longevity of the prosthesis and implant with biomechanical and clinical advantages.

[0002] The System of Triple abutments with Tconnect describes T- abutments for partial fixed cases for pacients that require placement of at least three dental crowns in areas as from 16 mm and cannot fix more than one osseointegrated implant and only one abutment in edentulous area with counter-indication for bone graft.

[0003] This system includes correlated use of: T-abutments, for new total segmented fixed rehabilitations too, T-Over and Plug T, for overdentures in pacients that require overdentures which can only be supported by only one osseointegrated implant and one T-Over; T- healings, with the purpose of modeling the new and especific design of Tconnect in the periimplantary region during the waiting phase; and T- Guides, which are specific guides for implants, to orient the surgical positioning of implant fixation in according with prosthetic planning of the System of Triple abutments with Tconnect, and increase the predictability of the final oral rehabilitation.

[0004] Patients with edentulous areas were characterized by severely resorbed bone ridges, inferior bone quality and little bone quantity too. Limitations such as severely resorbed jaws, unfavorable jaw relations due to bone loss and financial restrictions, sometimes prevent the placement of a sufficient number of implants and therefore require an alternative for edentulous patients with compromised oral function.

[0005] Solutions are indicated in accordance with each clinical case, for example, in partial areas between 16mm and 32mm are performed fixed bridges with welds, but remain the difficulty in obtaining the total passivity of the metallic structure, always over two or more implants.

[0006] Fixed solutions in state of art for total edentulous, with or not addition of bone grafts, are total fixed denture-protocol type, with metallic bar and cantilevers, or fixed prostheses with welds over several implants, preventing the ideal passivity and longevity of the system.

[0007] Overdentures solutions are applied to cases of removable total prosthesis, with at least two paralel implants, bars and attachments. With a lower support area of retention, occurs difficulty of obtaining the passivity of the prosthesis, lower stability, and fractures are defects often found. Loss of implants are also described in the literature.

[0008] One traumatic factor recognized in total oral rehabilitation with osseointegrated implants in state of the art is the presence of cantilever extension(s), that increases of lever arm and make a gradual overload, which may generate tensions concentrated on the cervical implants and marginal resorption, with bone loss in the periimplantary region. Repeated complications are associated with increased mechanical problems at a medium or long term.

[0009] Another limitation of the state of the art in total or partial fixed dentures isa decrease in the occlusal vertical dimension and the lack of facial support to the lips, making the bone graft almost obligatory, or the use of acrylic or chromatic flanges to restore this bone loss.

[0010] Other aspect encountered in state of the art is the difficult cleaning dependent of accessories by the limited access and difficulty of handling. Biomechanic problems added to this factor of difficult cleaning, compromise the longevity of the prosthesis and increase the risk of perimplantites, local damaging factor that can promove to loss of implants.

[0011] In a search for references in patent databases, a technology similar to the invention described herein was found, in Brazilian patent application PI0505827-9 and US20080293012 which relates to a geminated Abutment (Splint abutment) for a single implant, but which allows the placement of only two crowns over a only implant but resolves limited cases at a distance of edentulous areas of up to 16.0 mm. The PI 0505827-9 also does not describe the new design of support Tconnect, and not has T-over and Plug T too. A Brazilian patent application BRPI0800298A2 which relates to a pillar system designed to enhance the implant based-dental reconstruction. The pillar system enables the placement of two or three crowns one or two dental implants. Another type of prosthetic implant is disclosed by document AU 2017 100 686 A4 which particularly relates to an auricular prosthesis.

[0012] US patents 6305938 and 6319000, for example, present a prosthetic bar of protocol-prosthesis type, an integral supporting element including a planar surface substantially perpendicular to the central axis for engagement with a bearing surface on the base supported on various implants. This prosthesis has some limitations, such as the difficulty in cleaning, absence of segmentation and lever arm (cantilever), besides not solve the problem of the partial edentulous areas.

[0013] On the other hand, US patent 4906191 proposes a solution for partial edentulous areas, a dental bridge for a dental prosthesis, but with a greater number of implants with precise parallelism and with predetermined space, to avoid absence of passivity.

[0014] The above-mentioned patents do not solve a large number of problems still existing in the state of the art, such as that of patients with few bone availability, with edentulous areas between at least 16.0 mm with impossible to fix more than one osseointegrated implant in these areas and counter-indication of bone graft.

[0015] Moreover, another novelty can be seen in the prosthetic solution proposed by the present invention, which uses a only one implant and one Triple abutment supporting at least three prosthetic crowns, or one T-Over with Plug T supporting in one overdenture with complete passivity, in order words, this new system includes resolutions for wider areas, with support for at least three dental crowns or total overdenture over a only one osseointegrated implant.

[0016] Today, in relation of traditional systems of overdenture, all forms presented on the market today still are supported directed or indiretament by attachments (a ball attachment or magnetic retention systems) and one metallic bar over at least two parallel osseointegrated implants bringing biomechanical disadvantages, with imposition stresses on the attachment parts, from the overdenture to the implants which causes constant exchanges of components and affect the stability of the set, shortening the life of the dental prosthesis and attachment components. Biomechanically, occour progressive residual ridge resorption and attachment wear with increase the rotational movements of overdentures during mastication.

[0017] For example, US 4488875 describes a connector for overdenture through of two parts for stabilizing of prosthesis in the mouth: one being adapted to be anchored directly or indirectly to the jawbone and the other parts being a spherical part or ball adapted to be attached to project therefrom and to enter said socket; In other example, US 20100105005 reveal a dental prosthesis implant system having an o-ring retention device according to one embodiment; all with biomechanics problems.

[0018] In brief, the above-mentioned patents do not solve a number of problems still existing in the state of the art. The System of Triple abutments with Tconnect unlike the previously described, with simplified form and better biomechanic promoved by TConnect, replace at least three dental crowns in partial fixed cases or an overdenture in total removable over one only abutment, ideal for cases when there is an impossibility to fix more of one implant, because has little bone or counter-indication of bone graft.

[0019] The possibility of use the T abutments and T Over, with total passivity inserted in piece, allows pre- passivity in abutments of the new System, due to absence of welds , bars and cantilevers.

[0020] The System of Triple abutments with Tconnect allows a rehabilitation without the obligation of parallel implants because there is no need for welds or bars between the abutments too.

[0021] The System of Triple abutments with Tconnect allows the possibility of corrective angulation in the piece itself or through the use of the Compensatory Corrective Slanted Coping.

[0022] The fitting of the prosthetic crowns on the T abutments of the System and the adaptation of the overdentures of TOver happen in the contour of the Tconnect, far from the area of connection of the implants, avoiding extravasation of cement to the perimplant region, and avoiding traumatic forces in the implants and connections with consequently loss of implants.

[0023] System of Triple abutments with Tconnect promove T -Over abutment with the advantages of use only one abutment supporting a total superior or inferior removable prosthesis not requiring parallelism between the implants and has greater area of support of the Tconnect, than the area of support of the traditional overdentures (ball type, bar or clip, all of cylindrical socket).

[0024] Other diference occour in the adaptation of the overdenture that happen in contour of Tconnect , different from traditional overdentures, which the fitting and overload occours on implant connections or attachments, with frictional wear process, this being the cause of many failures in overdentures.

[0025] All healings used in the market of implants are of cylindrical profile, as in the patent US5336090, whereas in the System of Triple abutments with Tconnect promove T- healings with possibility of tissue healing guided by the multidimensional profile of the new design of support Tconnect. modeling post-surgical areas according to Tconnect's non-cylindrical design.

[0026] The invention described herein , System of Triple abutments with Tconnect contains: T- abutments, T -Over abutments and Plug T, T- healings and T-guides, all components with Tconnect the innovator design support with multidimensional contour and paraboloid shape in double curvature and with three pins, with height ranging from 3.0 mm to 20.0 mm each, rounded , tapered, square, or rectangular shape, expulsive for the occlusal, disposed in the form of a tripod arrangement (in triangular arrangement) over only one implant . The central pin should be positioned slightly towards for the vestibular (buccal direction) or lingual direction with respect to the others, in tripod format, and central region is coincident with implant fixation area with small variation of positioning, compensated in angulations in the T-Abutment itself. These pins can be subdivided or not, interconnected or not, with space between the two pins ranging from 2.1 mm to 10.0 mm, for pacients that require placement of at least three dental crowns and cannot fix more than one osseointegrated implant and only one abutment in edentulous area with counter-indication for bone graft and too for pacients that require overdentures which can only be supported by only one implant for the same reason. Another great advantage and option is the fixed total segmented arrangement, without bars,welds and cantilevers promoting the prepassivity of the system and decreasing of various laboratory stages and costs, because of the promotion of pre-passivity in all types of abutments of System.

[0027] These pins and the Tconnect can be coupled or dismembered in parts and all the components of the System of Triple abutments with Tconnect can be production in prefabricated form, usined and customized, including in CADCAM-software format.

[0028] The Tconnect, by means of his design, with paraboloid shape contour, provides positive vertical shield and lateral stability to limit the applied forces, allows a better distribution of forces on the prosthesis before reaching the implant, a fundamental advantage for use of the immediate load and use of a only one osseointegrated implant for each abutment of system.

[0029] The possibility of the use of immediate load too avoid migration of soft tissues, constant in abutment disconnections, being traumatic prosthethic procedures and harmful to the healing of the soft tissue. Promove biological and aesthetic predictability to the system and proper healing in less time.

[0030] The Tconnect presents greater resistance because of the double curvature design, where tension and compression loads are canceled out, and, as a result, the load is transferred to the support edges with intensity of tensions better distributed in all abutments of system, allowing the use of the one abutment and only one osseointegrated implant. Tconnect has excellents physical properties, enables that all the components of these System can be produced with less material, in membrane or rind type, having less weight and lower costs.

[0031] .System of Triple abutments with Tconnect innovates in the simplification of all surgical and prosthetic processes, avoiding large and highly invasive bone grafts, because TConnect support fills the space lost by bone resorption and reestablish the maxillo-mandibular relation in the transversal and sagittal dimensions comprising adequate facial height, without using acrylic flanges and also reworking the lip support.

[0032] The System of Triple abutments with Tconnect are indicated for partial fixed cases with adaptation at least of the three prosthetic crowns in each T- abutment in areas at least from 16 mm, and only one implant or total fixed cases with new segmented arregement not using bars, welds or cantilevers, and removable total prosthetic reconstruction, type overdenture with T-over and Plug T, all with Tconnect and passivity inserted in all abutments.

[0033] In cases of total fixed rehabilitation the System promove innovative form of fixed total segmented arrangement through the use of only four fixed T-abutments in each arch ,with numerous advantages over the traditional total format (protocol type) since it allows the exchange of its components separately, and in the case of any wear of pieces, without others having to be modified., not affecting all prosthetic set.

[0034] Other advantage of the prosthetic segmentation, that allow the better distribution of masticatory forces as in the natural dentition, where work and balance forces occur, acting at differentiated points and moments and not on a single rod, at the same moment, bringing forces with overload for mandibular temporal articulation and all components of the system.

[0035] Another advantage of the fixed total segmented arrangement is the possibility of easy and hygiene without prophylactic accessories, which does not happen in the conventional total prosthesis, in state of the art, and is one of its major drawbacks, with loss of implants due to to the perimplantites due to the this difficulty.

[0036] In the traditional form, for edentulous total with type overdenture, are made at least two implants. With T-over Abutments, overdentures can be supported by just one only implant, due to biomechanical advantages presented by new support Tconnect, larger in its dimensions than in Triple Abutment, and with easier implementation of procedures in relation of traditional systems of overdenture, with pre-fitting of the prosthesis with prepassivity already defined by the contour of the T-Over abutment and Plug T, with the advantage of the area of support is greater than the area of support of the traditional overdentures, to compensate local bone loss and for precision settlement of overdenture. not requiring parallelism between the implants, which improves the surgical conditions and reduce the cost of treatment, allowing a greater number of people to benefit from treatment.

[0037] Other diference these system occour in the adaptation of the overdenture will happen in contour of Tconnect , different from traditional overdentures, where the fitting and overload occours on implant connections or attachments, with frictional wear process, this being the cause of many failures in overdentures.

[0038] The Plug T (plug-type) is the ajustable dispositive piece which makes the precise coupling between the prefabricated prosthesis in the abutment TOver. The coupling of the Plug T in Tconnect of T-Over Abutment can be male-female type, button, pressure, magnet, or other. The Plug T garante pre-fitting of the prosthesis with prepassivity ,decreasing various laboratory stages in relation to the state of the art and guaranteeing longevity to the system.

[0039] The adaptation of the Plug T occur internally in the area of overdenture prosthesis through use of drills and acrylic rebasing or resin for intern coupling. The final prosthesis type overdenture can be pre- confectioned or can also be modeled after installed abutment T-over and Plug T or customized in CAD- CAM service-software or similar system, allowing a better accuracy of the system.

[0040] The Tconnect of T-Over Abutment, is larger in its dimensions than in T-Abutment and with area of support of Tconnect greater too, to compensate local bone loss and for precision settlement of overdenture with full precision adjustment and receiving the efforts off the masticatory loads, slowing efforts to implants and connections.

[0041] Through of Plug T and Tconnect in T-Over, happens a safe anchorage to the overdentures and not happen friction in the docking area between implant and connection, as in traditional overdentures. Since the full force is distributed throughout the area of Tconnect, and the prosthesis fitting is delimited away from the area of connection of implant. These characteristics promote the longevity of the system, avoiding constant problems, communs in state of the art: changes of screws and breaks, including loss of implants, increased reabsorption of remaining bone tissue, lesions due to lack of retention and stability, inducing masticatory deficiency (grinding of food) leading to failure in the restoration of the individual's quality of life.

[0042] The System of Triple abutments promotes too T-healings being screwed or pressure, or other fitting plug type, with digital marks for sensorial confort used to characterized paraboloid shape contour of the Tconnect during the hold phase of gingival healing, modeling the new design of System in the periimplantary region during the waiting phase, avoiding reopenings and new surgeries in cases of clinical difficulty in choosing an ideal previous abutment or when not has condition to use the immediate load.

[0043] The System of Triple abutments promotes too T- guides, a guiding to surgical perforation, which should be in accordance with the idealized prosthetic planning, for guide the perforation of the implants and pre-definition of abutments chosen, increasing the predictability of the final oral rehabilitation.

[0044] The T-guides will orient the planning and setting of the implant in partial or total edentulous areas in accordance with the treatment planning and will facilitate the surgical performance since they have the same dimensions of the of the Triple abutment described.

[0045] In the case of angled implants, System of Triple abutments with Tconnect, have the inclination of the compensation of the piece itself, in the design of the Tconnect that can be calcinable or personalized type project for individualization of parts, with variation between 10° and 30° with the implant insertion axis.

[0046] All the components of these System are adaptable to all types of implant / abutment connections of market, whether internal or external connections, hybrid connections, compensatory slant corrective, converters and extenders or adapted in any other interface of market and can be manufactured from titanium, carbon, gold, chromium-cobalt, tillite, niobium, zirconia, alumina, ceramic, resin, calcinable material, be usined or individualized process in type CAD-CAM or similar, and can receive surface treatment.

[0047] All the components of these System can be produced with less material, in membrane or rind type, having less weight, lower costs, ensured by the physical properties of hyperbolic paraboloid shape contour presented of Tconnect.

[0048] The biggest advantages of structures type rind or membrane are in sufficiently thin so as not to develop flexing stresses, but thick enough to resist tensile load, shear and compression, what guarantees predictability to the system as well as comfort and safety to the patient.

[0049] Tconnect that provides positive vertical shield and lateral stability ,allows a better distribution of forces on the prosthesis exhibiting favorable biomechanical properties and pre passivity adquired in abutments of System, without welds, fundamental advantages for use of the immediate load and of only one implant for each abutment of system.

[0050] T- abutments and T-Over have adjustable height of 1.0 mm - 20.0 mm , the buccal- lingual distance varying from 8.0 mm to 20.0mm is the mesio distal distance varying from 16.0 mm to 40mm.

[0051] All the abutments of these system have bored-through areas of 3.0 mm to 18,0 mm for passage of the fixing screw or are compact, that is, without bored-through areas in the implant / abutment connection, for cases of conical connections, without screws, as Morse cone type and cold welding.

[0052] All the abutments of these system has in its base of T-connect one girdle of 2,0 mm to 10 mm with one narrowing in perimeter of girdle of 0.7 mm to 6.0 mm for gingival biological accommodation on the implant platform.

[0053] These inventions imparts better passivity by eliminating the steps of fusing, molding and welding points, facilitating the operating and clinical and laboratory techniques ,superior biomechanics properties, predictability and reduction of the clinical time, ensuring longevity of the results.
