Definitions
- the present invention relates to a dental implant that has an anchoring system consisting of deployable flaps driven by an insertion screw. Likewise, the present invention discloses the uses and advantages that this dental implant offers with respect to other products of the sector.
- dental implants are medical devices designed to replace the root of a tooth that for any reason is no longer present, as well as having the function of keeping the artificial tooth in place. Undoubtedly they are a safe and lasting solution to the loss of one or several teeth. That is why they have developed innumerable types of dental implants and placement techniques, all of them aimed at trying to meet the medical needs of each patient.
- dental implants Another very appreciated requirement in dental implants is their primary stability, which is also essential for an optimal long-term osseointegration process to be carried out. Once this stability is reached, it is important the quality of it, how fast and biomechanically strong it can be, depending in most cases of the presence of adequate anchoring systems.
- the inventor of the present invention has developed a new dental implant that has an anchoring system consisting of deployable flaps driven by an insertion screw. Additionally said dental implant has a porous structure with trabecular shape, located particularly in the body thereof.
- a) implant body comprising an implant-abutment connection zone, an external threading area, at least one pair of outlet orifices and an internal threading area,
- anchoring comprising at least one pair of fins and an upper hole
- insertion screw comprising a head with hexagonal internal connection, a rod and a thread, where the insertion screw is positioned in the upper hole of the Anchoring and threading pushes said anchor down the inside of the body of the implant, allowing the exit of the deployable flaps through the exit orifices.
- the holes that make up the pair of exit holes in the body of the implant are located facing each other, ie in opposite positions one from the other, so that they correspond to the arrangement of the fins deployable of the anchor.
- the body of the implant is characterized in that a porous structure of trabecular shape is found in the external threading area.
- the porous structure is located in the inter-threaded spaces of the external threading area.
- the porous structure is highly osteoconductive, thus allowing rapid invasion by the vascularized fibrous tissue, favoring the incorporation of the surrounding bone 3 to 5 times more than on other rough surfaces.
- the action of the pores results in a double effect.
- it produces a mechanical coupling with the bone and on the other it has a biological effect exerting a direct and indirect influence on the cells and their metabolism.
- the pre-osteoblasts show a kind of "Poro-filia" and the signals it receives from the surface depends on its gene expression, differentiation and deposit of matrix that will be mineralized.
- the external threading area is a double thread, this allows the distance between the thread pitch to be increased, less bone is eliminated during the insertion of the implant, we also reduce the heat generated and we increase the insertion torque in low density bones.
- the external threading area has a thread pitch of between 0.5-2 mm, more preferably the thread pitch is 1 mm.
- the body of the implant has a self-piercing thread at its lower end.
- This self-drilling thread has the ability to change the orientation of the implant during the placement process, in this way it allows to achieve a correct parallelism between implants and optimize their placement.
- the implant-abutment connection zone has an angle of between 10 ° -20 °, more preferably the angle is 16 °.
- a remarkable feature of the present invention is that the implant-abutment connection zone is by fixation with morse taper, which allows the decrease of the microgap between the implant / abutment connection since it increases the contact surface between them, in this way bacterial microfiltration is minimized so that bone resorption decreases keeping the soft tissues stable with a better long-term aesthetic result.
- the morse cone connection absorbs the vibration and pressure exerted on the abutment, preventing loosening of the prosthetic screw.
- the anchor comprises at least one pair of fins and one upper hole.
- the fins slide inside the body of the implant as the insertion screw exerts force on said anchor.
- the anchor is made of titanium due to its high mechanical strength, which makes it possible to deploy its fins by the action of the insertion screw, as well as the retraction of said fins if it were necessary to remove the implant.
- At least one pair of anchoring fins will anchor in the cortical wall of the jaw or maxilla as the case may be.
- both the coils that make up the external threading area of the implant and the deployable flaps constitute primary stabilization elements, especially in non-dense type (IV) bones, which have a thin cortical layer.
- IV non-dense type
- dental implants with reinforced fixation elements are required, especially towards the upper-middle part of the implant and not especially at its lower end. It is for this reason that also in this area, in a preferred embodiment of the present invention, there is the porous structure of trabecular shape that facilitates greater proliferation and cell migration thus allowing the growth of bone tissue in its interior.
- this allows or makes possible the connection between the anchor itself and the insertion screw.
- this comprises a head with hexagonal internal connection, a rod and a thread.
- the internal hexagonal connection facilitates the manipulation of the screw, both in its insertion and in the extraction of the dental implant, by means of the corresponding instruments.
- the rod In the case of the rod, it is located inside the upper hole of the anchor, while the thread allows the insertion screw to rise and fall through the internal threading area of the implant body, leading the pin through its interior to the outside of the implant.
- the configuration of the insert-screw assembly allows both the placement, by threading the dental implant, and its removal or removal, by unscrewing, since in the threading operation the head with hexagonal internal connection of the screw Insertion pushes the anchor into the implant, while, in the opposite operation, the screw thread pushes the anchor towards the top or outside of the implant.
- the manufacturing process of the dental implant object of the present invention it will be by additive (addition of material by layers) by means of a 3D printer.
- the concept of 3D printing has evolved the technology of additive manufacturing, from a 3D CAD file. It is a good alternative when the geometry of the object to be manufactured is very complex and its size is relatively small, as is the case of the dental implant of interest.
- Figure 1 Represents a schematic view of the different elements that make up the dental implant object of the present invention.
- Figure 2 Represents a schematic view of the dental implant object of the present invention that has a trabecular porous structure in the inter-threaded spaces of the external threading area.
- Figure 3 Represents a top view of the body of the implant.
- Figure 4. Represents a schematic view corresponding to a cross section of the body of the implant.
- Figures 5A and 5B represent a schematic view of the dental implant with all the elements that make it up.
- figures 1-4 show the dental implant (1) object of the present invention, through the main elements that comprise it.
- the dental implant (1) with deployable flaps (8) is characterized in that it comprises the following elements: a) implant body (2), comprising an implant-abutment connection zone (3), an external threading region (4), at least one pair of outlet orifices (5) and an internal threading region (6) ),
- anchor (7) comprising at least one pair of deployable fins (8) and one upper hole (9),
- insertion screw (10) comprising a head (11) with internal hexagonal connection, a rod (12) and a thread (13),
- the insertion screw (10) is positioned in the upper hole (9) of the anchor (7) and by threading it pushes said anchor (7) down the inside of the body of the implant (2) and the exit of the fins deployable (8) through the exit holes (5).
- the dental implant (1) has a porous structure (14) in the upper-middle area of the implant. Specifically in the external threading area (4) there is a porous structure (14) of trabecular shape. Specifically, said porous structure (14) is located in the inter-threaded spaces of the external threading area (4). This porous structure (14), located in the upper-middle area of the implant, facilitates the osseointegration process of said dental implant (1). Additionally, it is appreciated that the body of the implant (2) has a self-piercing thread (15) at its lower end.
- Figure 3 shows a top view of the implant body, in which the implant-abutment connection zone (3) and the internal threading area (6) can be seen.
- Figure 4 shows a schematic view corresponding to a cross section of the body of the dental implant (1). It is possible to appreciate a pair of outlet holes (5), an external threading area (4) and an internal threading area (6).
- the external threaded area (4) is a double thread.
- Figure 5A shows how the insertion screw (10) is positioned in the upper hole (9) of the anchor (7), before carrying out the assembly of the dental implant (1).
- the anchor (7) When performing the threading operation, the anchor (7) is forced to lower inside the body of the implant (2), by the action of pushing down that makes the insertion screw (10), so that the flaps are deployable (8) exit through the exit holes (5) to the cortical area of the jaw or maxilla where they will be anchored.
- the provision adopted by the different elements of the dental implant (1) after said threading operation is shown in figure 5B.
