Healing Body System

Abstract

The present invention discloses a healing body system based on a healing body assembly comprising a healing body base (2) and a gingival extension (4). The apical section of the gingival extension (4) is externally placed over the coronal portion of the base (2) with an anti-rotation element attached, and the through-holes are coaxially connected to form a common through-hole into which a base screw (3) for fixing the assembly to the implant and a healing body plug (5) for fixing the gingival extension (4) to the base (2) are inserted. Furthermore, the system comprises impression pins and scanning bodies for analog and digital impression taking, screws for fixing them, control pins for controlling the position of the implant, and an implant plug. The system addresses all aspects related to dental implants, namely, both the shaping of bone tissue during implant healing and the shaping of soft tissue during subsequent adjustment.

Description

Technical Field

[0001] The present invention relates to a healing body system aimed at creating a high aesthetic appearance of soft gingival tissue after the introduction of a dental implant, and serves to shape the soft tissue above the dental implant into an optimal state for the design, function, and aesthetics of future prostheses, thereby maintaining the lifespan of the dental implant. Thus, the present invention relates to the dental industry, particularly the field of implants.

Background Art

[0002] Dental implants for fixing one or more artificial teeth have been known for decades. Currently, there are hundreds of different dental implants on the market.

[0003] Existing means for shaping the soft tissue above the implant are usually called so-called healing rollers or healing abutments. These are always inserted into the introduced dental implant and function as a body that is covered (grows) by the soft tissue during the healing process.

[0004] U.S. Patent No. 6,129,548 discloses a two-piece healing abutment including a body and a screw for attaching the body to a dental implant.

[0005] U.S. Patent Application Publication No. 2011 / 200967 discloses a dental healing abutment assembly having a tubular holder and a plurality of detachable nested shells having through holes for accommodating attachment members for fixing to a dental implant.

[0006] U.S. Patent Application Publication No. 2011 / 244425 discloses a general-purpose dental treatment abutment having a circumferential body that can be attached to a dental implant, a tapered lower section, and a central through-opening for attachment to the implant using a screw, as well as a kit comprising at least one general-purpose healing abutment, at least one screw, and at least one crown.

[0007] U.S. Patent No. 5106300 discloses a dental implant mounting system comprising an abutment member, a fixing means, and an impression cap.

[0008] International Publication No. 2018 / 172261 discloses a two-part modeling aid for connection to a dental implant component, the modeling aid comprising a coronal end, an apical end, a through-hole extending from the apical end to the coronal end, a first anti-rotation means located at the apical end for cooperating with a dental implant, and a second anti-rotation means located at the coronal end for cooperating with an anti-rotation section of the base of the modeling aid.

[0009] The development of the healing body system according to the present invention began because there was no market-driven range of assistive devices that could meet multiple criteria in a single product. Existing methods are unsatisfactory for several reasons, including the following: - Not applicable to all implant systems. For example, it may be produced by an implantology system manufacturer and only compatible with that specific type of implant. - While the design is easy to manufacture, the shape is inappropriate. The shape is too simple, which may lead to unsatisfactory results from an aesthetic and health perspective. Therefore, healing soft tissues and prostheses molded using these materials do not have a natural and correct design. - Alternatively, even if the shape is correct from an aesthetic (anatomical) standpoint, it can only solve a limited number of cases. There may be a lack of the necessary parts in terms of size, or it may not be compatible with all types of fixtures from a particular manufacturer. - Impressions cannot be taken simultaneously using both analog and digital methods. In most cases, soft tissue molded by healing abutments is taken analogously using impression material. To take an impression of the situation, the healing abutment must be inserted and removed before the impression is taken, and as a result, the soft tissue begins to change during the impression, and its shape changes. This results in a significantly inaccurate impression, which is then copied to the plaster model and the shape of the denture. The correct conditions for the soft tissue are often overlooked, thus affecting not only the aesthetics of the result but also the durability of the modeled soft tissue, which tends to recede when overloaded. The inaccuracy of analog impressions is partially resolved by some healing abutment systems. These systems assume only digital impressions and have abutment shapes predefined in a digital library, which are then used for accurate denture design. However, these cannot solve the problem of analog impressions using impression material, which are sometimes necessary. - Using current assistive devices as the basis for individually crafted healing bodies, which are ultimately modeled manually by the surgeon during surgery, is laborious, time-consuming, and technically complex.

[0010] The healing body system brings new possibilities to the work process of dental implant specialists, allowing for the shaping of soft tissue above the position of dental implants at both the bone and tissue levels, simplifying and accelerating the work and thus reducing the burden on patients. This system addresses both aspects of bone tissue shaping during implant healing and soft tissue shaping during subsequent adjustments. [Overview of the project]

[0011] The aforementioned drawbacks of conventional technology are resolved by the healing body system according to the present invention.

[0012] In a first embodiment, the present invention relates to a gingival dilatation portion of a healing body for shaping the soft tissue above an implant, The gingival dilatation portion comprises a body having a through cavity extending in the crown-apical direction, the outer shape of which mimics the shape of the crown transition neck in at least the portion that contacts the soft tissue, - An annular apical abutment surface facing the apex is positioned at the apical end of the outer surface of the gingival dilation portion. - The through-hole in the gingival dilation portion is, - An apical section comprising an apical rotation prevention recess facing radially outward along a portion of the circumferential surface of the apical section at its apical end, and a coronal rotation prevention recess facing radially outward along a portion of the circumferential surface of the apical section at its coronal end, - A coronal section of any choice, which is coaxial with the apical section and whose cross-section along at least a portion of the circumferential surface of the coronal section is wider than that of the apical section, Equipped with, - The coronal abutment surface facing the tooth crown is formed in the transition area between the inner surface of the apical section of the through cavity of the gingival dilatation portion and the outer surface of the coronal end of the gingival dilatation portion, or between the inner surface of the coronal section of the through cavity of the gingival dilatation portion. It provides a gingival dilation area for healing bodies.

[0013] In another embodiment, the present invention relates to a healing body base for attachment to an implant, The base comprises a body having a through cavity extending in the crown-apical direction, and having a ring on its outer surface with an annular axial abutment surface facing the crown direction, wherein the base is divided into an apical portion and a coronal portion for attachment to the implant, the through cavity has a larger cross-sectional diameter at the coronal end than at the apical end, and the inner surface of the through cavity transitions from the cross-sectional diameter at the coronal end to the cross-sectional diameter at the apical end by a transition section in the apical portion of the base, - The crown portion has a tubular shape and has a flat crown abutment surface at the crown end of the crown portion. - At least one identification relief facing radially inward is provided on the outer circumferential surface of the coronal end of the aforementioned coronal portion. - A rotation-preventing projection facing radially outward is formed on the outer circumferential surface of the apical end of the crown portion of the tooth. - The through-hole is provided with an internal thread on the crown side at the crown-side end of the crown-side portion. It provides the foundation for a healing body.

[0014] In another embodiment, the present invention is a healing body assembly, - The base of the healing body defined above, - The gingival dilation area defined above, - Base screw and, - Healing body plug, Equipped with, The apical section of the through cavity of the gingival dilater is fitted from the outside onto the coronal portion of the base such that the apical abutment surface of the gingival dilater abutment contacts the axial abutment surface of the base, the anti-rotation projection of the base fits into the apical anti-rotation recess of the gingival dilater, and the through cavity of the gingival dilater and the through cavity of the base are coaxially connected to form a common through cavity of the healing body assembly. The base screw is inserted into the common through-hole of the healing body assembly such that the bearing surface of the head of the base screw rests on the transition section of the through-hole of the base, and the head of the base screw does not interfere with the space of the coronal internal thread at the coronal end of the coronal portion of the through-hole of the base, in order to secure the healing body assembly to the implant by an external thread at the apical end of the shank of the base screw. The healing body plug is inserted into the common through-hole of the healing body assembly to fix the gingival dilater to the base, and the external thread of the apical end of the plug's shank is screwed into the internal thread of the base such that the head of the plug rests on the coronal abutment surface of the gingival dilater. We provide healing body assemblies.

[0015] In dental implant treatment (healing) that does not involve immediate loading, an implant plug is used. This prevents improper future bone tissue growth and shapes the bone tissue around the implant, eliminating problems with subsequent application of the healing body system and eliminating the need to further correct (remove) overlapping bone. The implant plug is a one-piece, rotationally symmetrical screw with a head and shank, the screw having an external thread at least at its apical end for attachment to the implant, and the screw size is preferably M1.4 to M2.0, more preferably M1.4, M1.6, M1.8, or M2.0. The shape of the implant plug at the apical portion of the head is adjusted to the specific implant type and is preferably screwed in with a system driver. The implant plug is preferably made of metal, more preferably titanium alloy, most preferably Ti6Al4V titanium alloy. Depending on the implant placement level below bone level, the dentist selects an implant plug that allows bone to grow around it, and above the implant level, creates a clean opening for insertion of the healing body base. The crown height of the implant plug head is preferably in the range of 0 mm to 4 mm, more preferably 1 mm, 2 mm, or 3 mm. The outer diameter of the implant plug head on the crown side is preferably in the range of 2.9 mm to 8 mm, more preferably 2.9 mm, 3.3 mm, 4.1 mm, or 4.5 mm.

[0016] The healing body base is the basic support component of the healing body, which is placed on the implant and secured within the implant by a base screw (see below) that penetrates this component (the shape of the base is similar to the “interface” type components commonly used in implant dentistry). The base may preferably be made of any suitable group of materials including plastics, ceramics, and metals, such as polyether ether ketone (PEEK), polyether ketone ketone, or reinforced polymers reinforced with glass fibers, carbon fibers, and / or ceramic particles, dental hybrid ceramics, glass ceramics, lithium disilicate ceramics, cobalt-chromium alloys, zirconium dioxide, and aluminum oxide, more preferably titanium or a titanium alloy, and most preferably Ti6Al4V titanium alloy. At the apical portion, the base has a shape that allows for a complete connection with the implant’s contact (and seal) profile, including a joint for an anti-rotation element (the shape and dimensions of the apical portion vary depending on the type and size of the implant in which it is placed). The shape and dimensions of the base in the apical portion are derived from the shape and dimensions of the implant to which it is attached; therefore, there are variations in base size and type for different types of implants and their size series. The base always maintains a fixed position relative to the implant and is fixed by anti-rotation elements present in both the implant and the base, so that it cannot rotate relative to the implant after being connected and screwed into the base thread. The cross-section of the coronal portion of the base may preferably have a circular, elliptical, or oblong periphery, more preferably circular. The annular axis abutment surface is preferably perpendicular to the longitudinal axis of the base and more preferably extends directly outward from the outer surface of the base. The periphery of the annular axis abutment surface may preferably have a circular, elliptical, or oblong shape, more preferably circular. Preferably, the surface of the transition section of the through-lung of the base has a truncated cone shape.The through-hole of the base is preferably provided with an apical internal thread, preferably in the range of M1.4 to M2.0, more preferably M1.4, M1.6, M1.8, or M2.0, for screwing in the base thread and other threads of the system according to the present invention, such as the impression pin thread (see below), so that they do not spontaneously fall out of the base during handling. The coronal internal thread is preferably in the range of M2.0 to M3.5, preferably M2.5 or M3.0, and serves to secure the supported components. The coronal portion of the base is universal in a particular series of healing body systems, so that any gingival dilatation in this series can be placed on any base in this series. The number of identification reliefs is preferably 2 to 4, preferably 2 or 3, most preferably 3. The identification reliefs are preferably distributed along the circumferential surface of the coronal end so that each type of base (and therefore implant) can secure a single type of scanning body. For example, if there are three identification reliefs, the axis of the first relief forms a first angle with respect to the axis of the anti-rotation projection, the axis of the second relief forms a second angle, and the axis of the third relief forms a third angle. The first angle is preferably 0° to 350°, for example 73°, the second angle is preferably 5° to 355°, for example 143°, 153°, 163°, or 173°, and the third angle is preferably 10° to 360°, for example 287°. The axes of the individual reliefs preferably form an angle of at least 5°, more preferably at least 70°, with respect to each other. In the case of a small base having an elliptical or oblong coronal portion (for example, for SC implants from Straumann Holding AG in Basel, Switzerland), it is preferable that two identification reliefs are distributed along the circumferential surface of the coronal end, with the axis of the first relief forming a first angle with respect to the axis of the anti-rotation projection, and the axis of the second relief forming a second angle, wherein the first angle is preferably -45° to +45°, more preferably 0°, and the second angle is preferably 135° to 225°, for example 175°, 180°, or 185°.Preferably, the outer portion of the at least one identification relief lies on a virtual circle (or a corresponding virtual ellipse or oblong) with the outer diameter of the coronal portion of the base. On the side away from the circumferential surface of the coronal portion of the base, the identification relief and anti-rotation projection may have any suitable cross-sectional shape, such as a dashed or curved shape, but are preferably rounded, and most preferably arc-shaped. The base of each type and dimension of implant has multiple, preferably at least two versions, of apical portion heights, taking into account the different implantation depths of the implant relative to the bone boundary level. The total height of the base is preferably in the range of 4 to 15 mm, more preferably 6.35, 7.35, 8.1, or 9.1 mm. The coronal portion of the base has a height preferably in the range of 2 to 9 mm, more preferably 2.1 mm, and an outer diameter, i.e., maximum outer cross-sectional dimension, preferably 2.0 to 4.5 mm, more preferably 2.1, 3.3, 4.0, or 4.5 mm. The surface of the annular shaft abutment preferably has a maximum outer dimension of 2.9 to 9 mm, and more preferably is circular with an outer diameter of 4.1 mm.

[0017] The role of the gingival dilater is to shape the soft tissue above the implant. The gingival dilater may preferably be made of any suitable group of materials including plastics, ceramics, and metals, such as polyether ether ketone, polyether ketone ketone, or reinforced polymers reinforced with glass fibers, carbon fibers, and / or ceramic particles, dental hybrid ceramics, glass ceramics, lithium disilicate ceramics, cobalt and chromium alloys, zirconium dioxide, and aluminum oxide, more preferably titanium and titanium alloys, and most preferably Ti6Al4V titanium alloy. The gingival dilater can be placed on any base within one series of healing body systems. The perforation of the gingival dilater may preferably be circular, elliptical, or oval, more preferably circular. The through-space of the gingival dilater is preferably threadless, and the internal dimensions of the through-space in the apical section are such that the apical section can be positioned in the coronal portion of the base, and therefore correspond to the external shape and size of the coronal portion of the base. The dimensions of the cross section perpendicular to the longitudinal axis of the gingival dilater are preferably in the range of 2.02 mm to 4.52 mm, and most preferably 2.12 mm, 3.32 mm, 4.02 mm, or 4.52 mm. The coronal section of the through-space of the gingival dilater has a circular, elliptical, or oblong internal shape and is preferably formed to correspond to the outer diameter of the head of the healing body plug so that the healing body plug can always be inserted into the coronal section. The dimensions of the cross section perpendicular to the longitudinal axis of the gingival dilater are preferably in the range of 3.1 mm to 5.5 mm, and most preferably 3.12 mm, 3.32 mm, 4.02 mm, 4.52 mm, or 5.22 mm in diameter, and most preferably 3.32 mm in diameter. On the side of the gingival dilatation away from the penetration cavity, the anti-rotation recess can have any suitable cross-sectional shape, such as a dashed or curved shape, but it is preferable to have a rounded shape, and most preferably an arc shape. The construction height of each type of gingival dilatation will differ depending on the thickness of the soft tissue at the implant site.The selection of the height of the gingival dilatation is related to the selected height of the healing body base, and the combination of both components is determined by the dentist. The total height of the gingival dilatation is preferably in the range of 2.5 mm to 10.0 mm, more preferably 2.5 mm, 3.5 mm, 5.0 mm, or 7.0 mm, while the height of the apical section is preferably in the range of 2.08 mm to 2.5 mm, more preferably 2.08 mm or 2.48 mm. The gingival dilatation has a specific position relative to the base and therefore also relative to the implant, and this position is determined by the anti-rotation projection of the base and the apical anti-rotation recess of the gingival dilatation, which has a complementary shape. This is necessary because the gingival dilatation has an asymmetric shape, and the gingival dilatation is always designed to match the specific position of the implant within the jaw arch, and the desired shape and aesthetics of the healed soft tissue are ensured only by the correct rotational position of the gingival dilatation in the antral direction. Therefore, during implantation of a dental implant, the subsequent application of the healing body system must be considered, and the correct rotational position of the implant, and consequently the correct rotational position of the entire subsequent assembly of the healing body, must always be ensured. This is achieved by using a control pin (see below) to which a control device—a gingival dilater—is attached during implantation (screwing the implant into the bone), thereby enabling very precise positioning of the implant. There are various (shapes and sizes) of gingival dilaters that perform functions according to specific locations and soft tissue heights in the jaw. The upper surface shape of the gingival dilater is derived from the upper surface shape of each tooth, while the gingival dilater at the coronal end preferably maintains this shape for a distance of 2 mm, after which the gingival dilater preferably gradually narrows to the shape and size, preferably the diameter, of the base ring. Thus, the gingival dilater preferably has an outer dimension in the range of 2.9 mm to 9 mm at the apical end, and more preferably has a circular shape with a diameter of 4.1 mm.

[0018] The base screw is intended to fix the base of the healing body to the implant, is similar to the system screw for each type of implant, and is preferably tightened with a system driver. It is preferably made of metal, more preferably made of a titanium alloy, and most preferably made of a Ti6Al4V titanium alloy. Its external thread preferably has a size in the range of M1.4 to M2.0, and more preferably is M1.4, M1.6, M1.8, or M2.0. The height is preferably in the range of 5.0 mm to 15.0 mm, more preferably 6.7 mm, 7.0 mm, or 8 mm, and the outer diameter of the head at the crown side end preferably has a diameter in the range of 1.9 mm to 2.5 mm, preferably 2.1 mm, 2.2 mm, or 2.4 mm.

[0019] The healing body plug is a screw-shaped part that has two functions: pulling the gingival expansion part towards the base of the healing body and simultaneously closing the internal opening of the gingival expansion part in the crown-apical direction from the occlusal side to prevent the intrusion of dirt into the internal space of the implant / base / gingival expansion part / plug assembly. This is a general component in all assemblies of a given series of healing body assemblies, preferably all assemblies of multiple series. By screwing the plug into the internal thread on the crown side of the base, a fixed connection of the set of implant / healing body base / gingival expansion part is created as a functional assembly of the components. The plug of the implant body is preferably made of metal, more preferably made of a titanium alloy, and most preferably made of a Ti6Al4V titanium alloy. Its external thread preferably has a size in the range of M2.0 to M3.5, more preferably M2.5 and M3.0, and is preferably screwed in with a system driver. The height is preferably in the range of 2.0 mm to 13 mm, more preferably 2.0 mm or 3.0 mm, the outer diameter of the head is preferably in the range of 3.0 mm to 5.5 mm, more preferably 3.0 mm, 3.2 mm, 3.9 mm, 4.4 mm, or 5.1 mm, and most preferably 3.9 mm.

[0020] In another aspect, the present invention provides an impression pin, which has a through-hole extending in the crown-apical direction and has a shape of a hollow cylinder with a through-hole having a cross-sectional diameter larger at the crown-side end than at the apical-side end. The inner surface of the through-hole transitions from the cross-sectional diameter at the crown-side end to the cross-sectional diameter at the apical-side end by a transition section. Fixing means for fixing an impression material is disposed on the outer surface of the crown-side end of the cylinder. A screw section having an external thread and having an outer diameter smaller than that of the cylinder is formed at the apical-side end. A crown-side bearing surface facing the apical direction is formed at the transition portion of the outer surface between the screw section and the cylinder. and provides the impression pin.

[0021] In another aspect, the present invention provides an impression pin assembly, - a base of the healing body defined above, - a gingival expansion portion defined above, - an impression pin defined above, - an impression pin screw, and comprises The apical-side section of the through-hole of the gingival expansion portion is covered from the outside on the crown-side portion of the base such that the apical-side abutment surface of the gingival expansion portion abuts against the axial abutment surface of the base, the anti-rotation protrusion of the base fits into the apical-side anti-rotation recess of the gingival expansion portion, and the through-hole of the gingival expansion portion and the through-hole of the base are coaxially connected to form a common through-hole of the healing body assembly. The apical-side end of the impression pin is inserted into the common through-hole of the healing body assembly such that the screw section of the impression pin is screwed into the crown-side internal thread of the base, the crown-side abutment surface of the impression pin abuts against the crown-side abutment surface of the gingival expansion portion, and the through-hole of the impression pin, the through-hole of the gingival expansion portion, and the through-hole of the base are coaxially connected to form a common through-hole of the impression pin assembly. The impression pin screw is inserted into the common through-hole of the impression pin assembly so that the bearing surface of the head of the impression pin screw rests on the transitional section of the through-hole of the impression pin, in order to secure the impression pin assembly to the implant by an external thread at the apical end of the shank of the impression pin screw. We provide an impression pin assembly.

[0022] An impression pin is a general-purpose component in a series of implant systems used to transmit the implant position to an impression when using an analog impression method with impression material. The impression pin may preferably be made of any suitable group of materials including plastics and metals, such as thermoplastic polymers, polyether ether ketones, polyether ketone ketones, reinforced polymers reinforced with, for example, glass fibers, carbon fibers and / or ceramic particles, cobalt and chromium alloys, zirconium dioxide, austenitic stainless steel, aluminum alloys containing one or more elements such as copper, magnesium, silicon, nickel, zinc, manganese or titanium, and aluminum oxide; more preferably titanium or a titanium alloy, and most preferably Ti6Al4V titanium alloy. In impressions using the open method, a fixing means for securely fixing the impression pin to the impression material is preferably provided on the coronal end, by ribs or grooves. Preferably, the fixing means is formed by projections and grooves running perpendicular to the longitudinal axis of the impression pin, with the grooves and surfaces arranged parallel to this axis. The apical end is intended to be inserted into the through-space of the gingival dilatation and screwed into the coronal internal thread of the base. The external thread of the threaded section has a size in the range of M2.0 to M3.5, preferably M2.5 or M3.0. In a preferred embodiment, the cylindrical body may not have the same outer diameter along its entire length, but may narrow in a section that starts away from the threaded section and extends coronally, thereby forming a wider section with a larger outer diameter than the cylindrical body of the impression pin, coronally from the threaded section at the apical end of the impression pin.More preferably, an intermediate section having a smaller outer diameter than the broad section and a larger outer diameter than the threaded section is positioned at the apical end of the impression pin between the broad section and the threaded section, thereby forming a coronal abutment surface at the transition of the outer surface between the intermediate section and the broad section, and forming an apical bearing surface facing the apex at the transition of the outer surface between the intermediate section and the threaded section, so as the thread of the impression pin is screwed in, it faces the coronal abutment surface of the base of the impression pin assembly. The maximum outer diameter of the cylindrical body at the apical end of the impression pin, or the outer diameter of the broad section, is such that the apical end of the impression pin can be inserted into the coronal section of the through-space of the gingival dilatation, and is preferably in the range of 3.0 mm to 5.5 mm, more preferably 3.0 mm, 3.2 mm, 3.9 mm, 4.4 mm, or 5.1 mm, and most preferably 3.9 mm. The outer diameter of the intermediate section is such that it can be inserted into the apical portion of the through-space of the gingival dilatation, and is preferably in the range of 2.0 mm to 4.5 mm, more preferably 2.1 mm, 3.3 mm, 4.0 mm, or 4.5 mm. The total height of the impression pin is preferably in the range of 8.0 mm to 25.0 mm, more preferably 14.6 mm. The impression pin is hollow, and an impression pin screw can be inserted into its cavity to fix the base / gingival dilatation / impression pin assembly to the implant. The internal cross-sectional diameter of the through-space from the transition section to the coronal side is preferably in the range of 1.9 mm to 3 mm, more preferably 2.2 mm, 2.3 mm, or 2.6 mm. The impression pin screw varies depending on the type of implant and is preferably tightened with a system screwdriver. The impression pin screw is preferably made of metal, more preferably of titanium alloy, and most preferably of Ti6Al4V titanium alloy.The impression pin screw preferably has an external metric thread in the range of M1.4 to M2.0, more preferably M1.4, M1.6, M1.8, or M2.0, the outer diameter of the crown-side head from the bearing top surface preferably ranges of 1.9 mm to 2.5 mm, more preferably 2.1 mm, 2.2 mm, or 2.4 mm, and its height preferably ranges of 20.0 mm to 35.0 mm, more preferably 26 mm. When using an impression pin, the entire assembly is left in the impression to record the accurate shape of the soft tissue when casting the plaster model. After the impression is made, the same combination of base / gingival expander components left in the impression by the dentist is inserted into the implant.

[0023] In another embodiment, the present invention provides a control pin for controlling the position of an implant, The outer surface of the control pin is an annular abutment surface with an annular axis facing the tooth crown, the annular abutment surface is facing the tooth crown, the control pin is divided by the annular abutment into an apical portion for attachment to the implant and a cylindrical coronal portion, an anti-rotation projection facing radially outward is arranged on the outer surface of the apical end of the coronal portion, and a control element is arranged at the coronal end of the coronal portion. Provides control pins.

[0024] In another embodiment, the present invention is a control pin assembly, - The control pins defined above, - The gingival dilation area defined above, Equipped with, The apical section of the through cavity of the gingival dilater is fitted from the outside onto the crown portion of the control pin such that the apical abutment surface of the gingival dilater abutment contacts the axial abutment surface of the control pin, and the anti-rotation projection of the control pin fits into the apical anti-rotation recess of the gingival dilater. A control pin assembly is provided.

[0025] Control pins are essential components for correctly positioning implants during implantation. The gingival expander must be precisely positioned within the jawbone to perform its function, and therefore, it needs to be maintained in the correct position during implantation (when the implant is screwed in). This can usually be largely achieved by marks on the implant's original transmission components, but using control pins allows for more precise positioning. The dentist places the selected gingival expander (depending on the implant's position relative to the jawbone) onto the control pin and inserts the control pin into the implant fixture. This allows the dentist to confirm the current rotational position of the implant or gingival expander. If the dentist then decides to change the implant's position, a control tool (preferably a ratchet or appropriate tightening wrench) is placed on the control element of the control pin (preferably polygonal, more preferably triangular to octagonal, even more preferably hexagonal to octagonal, most preferably octagonal) to rotate the implant to the desired position. The control pin may be made of any suitable material, such as an aluminum alloy containing one or more elements like copper, magnesium, silicon, nickel, zinc, manganese, or titanium, or a group of suitable materials including metals such as cobalt and chromium alloys or austenitic stainless steel, more preferably titanium or a titanium alloy, and most preferably Ti6Al4V titanium alloy. The apical portion of the control pin has a shape that conforms to the implant, as described above, similar to the apical portion of the base. The coronal portion of the control pin may have a cross-section that is preferably circular, elliptical, or oblong, more preferably circular. The control pin is fixed in place by anti-rotation elements present on both the implant and the control pin, preventing it from rotating relative to the implant and ensuring it always maintains a constant position relative to the implant. The anti-rotation projection is similar to the anti-rotation projection of the base and has a shape complementary to the apical anti-rotation recess of the gingival dilatation. On the side of the control pin away from the circumferential surface of the crown portion, the anti-rotation projection can have any suitable cross-sectional shape, such as a dashed line or a curved shape, but it is preferable to have a rounded shape, and most preferably an arc shape.The surface of the annular axis abutment is preferably perpendicular to the longitudinal axis of the control pin, and more preferably extends directly outward from the outer surface of the control pin. The periphery of the surface of the annular axis abutment may preferably have a circular, elliptical, or oblong shape, and more preferably a circular shape. The outer shape and dimensions of the coronal portion are such that a gingival dilater can be placed on it, and preferably its outer dimensions or diameter correspond to the inner dimensions or diameter of the apical section of the gingival dilater's penetration cavity, at least in the apical section of the coronal portion (which should be in the apical portion of the gingival dilater's penetration cavity after insertion of the gingival dilater), and more preferably in the range of 2.0 mm to 4.5 mm, most preferably 2.1 mm, 3.3 mm, 4.0 mm, or 4.5 mm.

A scanning body assembly is provided.

[0028] The scanning body is a component for digitally taking impressions of the implant position. The scanning body can be manufactured as a one-piece unit from one of the materials listed below for the body or head, but it is preferable to manufacture it as a two-piece unit, a combination of two materials, i.e., the body is made from one material and the head from another. The body of the scanning body is inserted into the opening of the gingival dilatation and fits into the relief at the coronal end of the healing body base. From the viewpoint of durability and functional accuracy, it is preferable to be made from one of a suitable group of materials, such as aluminum alloys containing one or more elements such as copper, magnesium, silicon, nickel, zinc, manganese, or titanium, or metals such as cobalt and chromium alloys, zirconium dioxide, or austenitic stainless steel, and is preferably titanium or a titanium alloy, most preferably Ti6Al4V titanium alloy. The scanning body head is preferably made of one of a suitable group of materials, including plastics such as thermoplastic polymers, polyetheretherketone, polyetherketoneketone, glass fiber, carbon fiber, and / or ceramic particle-reinforced polymers, and more preferably polyetheretherketone, in order to scan without problems using an intraoral scanner (IOS). The scanning body has a circular, elliptical, or oblong cross-sectional periphery, and more preferably a circular cross-sectional periphery. Scanning recesses (preferably bevels in the shape of circular segments) allow the scanner to identify the position and rotation of the scanning body. The head is preferably pressed against or bonded to the body. The coronal end of the body to which the head is attached preferably has a smaller outer diameter than the portion of the body continuous apex-side from the head, but more preferably there is a recess on the outer surface of the coronal end of the metal portion corresponding to the scanning recess, which functions as an anti-rotation element for properly connecting the two portions. The head preferably has an outer diameter in the range of 2.5 mm to 6.0 mm, more preferably 2.9 mm or 4.5 mm. The overall height of the scanning body is preferably such that the head protrudes from the penetration cavity of the gingival dilation area, more preferably in the range of 5 to 25 mm, and most preferably 10.53 mm.In a preferred embodiment, the cylindrical body has a wider cross-section (i.e., a larger outer diameter in the case of a circular cross-section) than the apical end of the body, at least along a portion of its outer surface, from the head of the coronal portion toward the apical portion, thereby forming an apical narrow section at the apical end of the body, and a coronal abutment surface is formed at the outer surface transition between the apical narrow section and the rest of the body, facing the coronal abutment surface of the gingival dilatation portion after the scanning body is fixed. In this embodiment of a scanning body having an elliptical or oblong cross-section, it is preferable that the wider portion is formed on both sides of the short axis of symmetry (or minor axis of the ellipse) of the ellipse, and in the case of a scanning body with a circular cross-section, it is preferable that the wider portion is formed around the entire circumference, and the coronal abutment surface is interrupted by an anti-rotation projection that has a larger outer diameter and extends radially to the height of the outer surface of the scanning body. The outer surface of the at least one identification projection facing radially outward and the inner surface of the anti-rotation projection facing radially into the through-cavity of the scanning body are preferably on a virtual circle having the outer diameter of the scanning body (or on a corresponding virtual ellipse or virtual oval), or, in the preferred embodiment described above, on a virtual circle having the diameter of the apical narrow section (or on a corresponding virtual ellipse or virtual oval). The inner surface of the at least one identification projection and the outer surface of the anti-rotation projection of the scanning body may have any suitable cross-sectional shape, such as a dashed or curved shape, but are preferably rounded, and most preferably arc-shaped. The number and distribution of the identification projections of the scanning body are defined in the same way as the definition of the identification relief of the base. In one preferred embodiment, the anti-rotation projection extends apically beyond the apical abutment surface by a shorter distance than the at least one identification projection. The thread of the scanning body can be inserted into the through-cavity of the scanning body, thereby securely fastening the scanning body to the coronal internal thread of the base. The screws of the scanning body are preferably tightened with a system screwdriver. The screws are preferably made of metal, more preferably of a titanium alloy, and most preferably of a Ti6Al4V titanium alloy.The external thread is preferably in the size range of M2.0 to M3.5, and more preferably M2.5 or M3.0. The internal bearing surface for contacting the head of the scanning body thread is preferably formed on the coronal side of the scanning body's through-hole, but can also be formed on the surface of the coronal end of the scanning body. The internal bearing surface is preferably formed such that the scanning body's through-hole narrows apically from the internal bearing surface or widens coronally from the internal bearing surface, and is formed in the transition area between the narrow and wide sections of the inner surface of the through-hole. The internal bearing surface is preferably extended coronally from the inner wall of the through-hole, and obliquely or perpendicularly to the through-hole. The scanning body's through-hole is preferably provided with threads of the size range of M2.0 to M3.5, more preferably M2.5 and M3.0, extending apically from the internal bearing surface, and the scanning body thread is preferably screwed in so that it does not spontaneously fall out of the scanning body during handling. As already explained above, the healing body base and scanning body each have a unique combination of identification and locking from identification reliefs and identification protrusions, so that a single scanning body corresponds to each type of base. The identification protrusions of the scanning body are shaped complementary to the identification reliefs of the base, and the anti-rotation protrusions of the scanning body are shaped complementary to the coronal anti-rotation recesses of the gingival dilatation, and the distribution (and number) of anti-rotation protrusions and identification protrusions along the circumferential surface of the apical end of the scanning body corresponds to the distribution (and number) of anti-rotation protrusions and identification reliefs along the circumferential surface of the coronal end of the base, as explained above. Thanks to this connection, the scanning body also functions as an identifier of the base used, in addition to its primary function (i.e., accurate scanning of the implant position). This unique feature can be used so that during scanning, the dentist does not need to remove all components above the implant and visually detect their type, but can simply loosen the healing body plug and insert the scanning body of the expected type into the cavity. When mated with the lock that defines the correct position, it can then be secured with a screw inside the body.If the type of scanning body is not selected correctly, the body cannot be placed in the correct position, cannot be secured with screws, and in the preferred circular embodiment, the body will also rotate within the gingival dilation area. Thus, when the dentist recognizes the incorrect selection, they select another scanning body from the limited set prepared for the procedure. This identification process makes it possible to determine both the type of base used and, importantly, the type of implant, thereby eliminating errors when the dentist identifies the base or implant used.

[0030] A preferred kit according to the present invention includes various combinations of the components and means described above, optional handling aids for handling them, and optional fastening tools such as screwdrivers, ratchets, or wrenches. It will be apparent to those skilled in the art that the individual components, means, aids, and tools are available individually, in larger packages, and in assemblies. A preferred kit would include a complete series of systems according to the present invention for a given implant system.

[0031] The heads of all the screw components described above (i.e., screws and plugs) can be knurled along their circumferential surface. The heads can be equipped with any element for a fastening tool (preferably a screwdriver), preferably a simple slot, a cross slot (e.g., Phillips, Pozidriv, etc.), a special slot (e.g., Tri-Wing, Torx Set, Spanner Head), a cavity in the shape of an internal polygon (e.g., square (Robertson), hexagon), a cavity in the shape of a polygonal star (e.g., Torx hexagonal star), a special cavity (e.g., Uni-Grip type), preferably a hexagonal cavity of 0.9 mm, 1.0 mm, 1.20 mm, 1.25 mm, or 1.4 mm in size, a Uni-Grip or Torx socket. Those skilled in the art will understand that it is most advantageous to provide a system element for a fastening tool on the heads of all screws in a system for a particular implant. The shanks of all the above-mentioned screw components (i.e., screws and plugs) may be provided with threads along the entire extension path of the shank, preferably at least near the apical end of the shank, and most preferably at least at the apical end of the stem.

[0032] In the system according to the present invention, it is preferable that all anti-rotation elements are arranged vertically relative to each other. In the elliptical or oval-shaped embodiment, it is preferable that the anti-rotation elements are positioned at the vertex of the longer axis of symmetry of the ellipse, or at the vertex of the major axis of the oval.

[0033] The materials constituting the above-mentioned components of the system according to the present invention are preferably biocompatible.

[0034] As used herein, the term "apical" refers to the direction of the root of the tooth. As used herein, the term "coronal" refers to the direction of the crown of the tooth.

[0035] As used herein, the term “section” means a section perpendicular to the longitudinal axis (i.e., the axis extending in the crown-apical direction) of a given component or part thereof.

[0036] A person skilled in the art will understand that when the shape of a particular component, element, part, or section is referred to herein as, for example, cylindrical, circular, elliptical, oblong, etc., the component, element, part, or section is substantially formed in such a shape, that is, part of the shape may include deviations from the shape, such as wide sections, narrow sections, protrusions, recesses, reliefs, or projections. A person skilled in the art will also understand that, for parts that are inserted into each other, there must be a gap between the outer wall of the inserted inner part and the inner wall of the outer part, which is expressed herein by the outer part being 0.02 mm larger in dimensions, but in practice may include a reasonable deviation from the stated dimensions.

[0037] As used herein, the term “system” (screws, drivers, elements, etc.) means a component (auxiliary device, shape) that is supplied (constructed) directly by a particular dental implant manufacturer and is suitable for or compatible with a particular implant system.

[0038] As used herein, the term "implant" refers to a hollow, screw-type dental implant that is screwed into the bone tissue of the patient's upper or lower jaw.

[0039] As used herein in relation to the individual components of the system of the present invention, the term “universal” means that a given component is broadly applicable within a particular embodiment of the system series, i.e., within an embodiment in which the dimensions of each cooperating part of the component correspond to each other.

[0040] The healing body system can be applied to dental implants at the bone and tissue levels, as well as all their dimensional versions. Therefore, the healing body system needs to have multiple series of shapes and sizes containing functionally identical individual components, but these components cannot be combined with each other between individual series due to differences in the size and shape of the transition and connecting elements. For one type of implant with multiple dimensional variations, it is preferable that the common series of the healing body system be defined such that some components within the series are specific to each implant size, while others are common (and thus these components are considered general-purpose within a particular series of the system).

[0041] The healing body system according to the present invention is an innovative system of unified components that makes the dentist's work easier, faster, and less error-free. Because this system is developed for general use, it can be applied to any implant system. It is designed for easy use when taking patient impressions using both analog (using impression materials) and digital (using intraoral scanners) methods.

[0042] The healing body system according to the present invention offers many advantages. - It is a complex system that includes everything a dentist needs to achieve effective results (both functional components and the tools necessary to properly apply each component). - Due to its variability, it can be applied to almost all types and sizes of dental implants used. - It covers commonly used transplantation techniques. - While offering dentists the option to select variable elements when different types of healing body bases are combined into one type of implant and different types of gingival expanders can be placed on top of them, the connection between the base and the gingival expander is universal, and the plug of the healing body is also universal. - Designed to eliminate potential user errors during the digital impression process using IOS, resulting in faster and more efficient work for dentists. - The base and scanning body have a unique combination of identification and locking mechanism, with a single scanning body corresponding to each type of base. This eliminates errors when dentists identify the base or implant being used. - Each component can be marked with a catalog code that is legible, as well as a matrix / QR code that can be read by an intraoral scanning camera. This allows the dentist to scan the scanning body (which records the implant position), the gingival dilatation, and the soft tissue surrounding the gingival dilatation all at once during a digital impression, and all the necessary information about the type of component used (implant fixation device, base, and gingival dilatation) is automatically recorded. - Because it supports both analog and digital impression taking, the shape of the soft tissues surrounding the body is always recorded completely and accurately, without deviation. - Thanks to its versatile components, the system can also be used advantageously in combination with other implant dental systems, saving on treatment costs.

[0043] The present invention will be further described by exemplary embodiments with reference to the illustrations in the drawings. It will be apparent to those skilled in the art that many changes, modifications, alterations or adaptations can be made to the present invention described herein without departing from the scope of the invention as defined in the claims. In particular, it should be noted that components that work in conjunction with an implant will always be adapted to a given implant, and therefore these components are shown in the drawings only as illustrative examples.
