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 high aesthetics in the soft gingival tissue after the introduction of a dental implant, which helps to shape the soft tissue above the dental implant in a way that is optimal for the design, function and aesthetics of the future prosthesis in order to preserve the life of the dental implant. Thus, the present invention relates to the dental industry, and in particular to the field of implants. [Background technology]

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

[0003] Existing means for shaping the soft tissue above the implant are usually so-called healing rollers or healing abutments, which are always inserted into the installed dental implant and act as a body onto which the soft tissue grows during the healing process.

[0004] US Pat. No. 6,129,548 discloses a two-piece healing abutment that includes 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 removable nestable shells having through holes for accommodating attachment members for securing to a dental implant.

[0006] US Patent Application Publication No. 2011 / 244425 discloses a universal dental healing abutment having a circumferential body attachable 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 including at least one universal healing abutment, at least one screw, and at least one crown.

[0007] US Patent No. 5,106,300 discloses a dental implant mounting system comprising an abutment member, a fixing means and an impression cap.

[0008] WO 2018 / 172261 discloses a two-part modelling aid for connection to a dental implant part, the modelling aid having a coronal end, an apical end, a through-bore extending from the apical end to the coronal end, a first anti-rotation means at the apical end for cooperating with the dental implant, and a second anti-rotation means at the coronal end for cooperating with an anti-rotation section of a base of the modelling aid.

[0009] The development of the Healing Body System of the present invention was prompted by the lack of a single assistive device on the market that could meet multiple criteria. Current existing solutions are unsatisfactory for several reasons: - Not applicable to any implant system, i.e. produced by the manufacturer of the implantology system and only compatible with this specific type of implant. - Easy to manufacture, but inappropriate shape. The healing soft tissue and prostheses produced by these methods do not have a natural, correct design, as the shape is too simple and may not achieve the correct results in terms of aesthetics and health. - Or, even if the shape is correct from an aesthetic (anatomical) point of view, it only solves a limited number of cases, does not have the required range of parts in terms of size, or is not compatible with all types of fixtures from a particular manufacturer. - Simultaneous analog and digital impression capture is not possible. In most cases, soft tissues shaped by healing abutments are captured analogically using impression materials. To capture this state, the healing abutments must be attached and removed before the impression is taken, which causes the soft tissue to begin to change shape during the impression. This leads to significant inaccuracies in the impression, which are then copied onto the stone model and denture shape. The correct soft tissue conditions are often overlooked, which not only affects the aesthetics of the result but also the durability of the modeled soft tissue, which tends to recede when overloaded. The inaccuracies of analog impressions are partially addressed by some healing abutment systems. These systems only consider digital impressions and have predefined abutment shapes in a digital library, which are then used to design precise dentures. However, they cannot address analog impressions using impression materials, which may be necessary in some cases. - Using current aids as the basis for an individually created healing body, which is ultimately manually modeled by the surgeon during surgery, is laborious, time-consuming and technically complex.

[0010] The Healing Body System brings new possibilities to the dental implantologist's work process for shaping the soft tissue above the location of a dental implant at bone level and tissue level, simplifying and speeding up the work and thus reducing the burden on the patient. The system addresses both aspects: shaping the bone tissue during implant healing and shaping the soft tissue during subsequent adjustment. Summary of the Invention

[0011] The above-mentioned shortcomings of the prior art are overcome by the healing body system of the present invention.

[0012] In a first aspect, the present invention provides a gingival extension of a healing body for shaping soft tissue above an implant, comprising: the gingival extension comprises a body with a through cavity extending in a coronal-apical direction, the body having an outer shape that mimics the shape of a transition neck of a dental crown at least in the portion that contacts the soft tissue; - an apically-facing annular apical abutment surface disposed at an apical end of the outer surface of the gingival extension; - the through-cavity of the gingival extension, - an apical section comprising an apical anti-rotation recess facing radially outwardly at an apical end along a portion of the circumference of the apical section, and a coronal anti-rotation recess facing radially outwardly at a coronal end along a portion of the circumference of the apical section; - an optional coronal section coaxial with said apical section and wider in cross section along at least a portion of its circumference than said apical section; Equipped with a coronally facing coronal abutment surface is formed at the transition between the inner surface of the apical section of the through-cavity of the gingival extension and the outer surface of the coronal end of the gingival extension or the inner surface of the coronal section of the through-cavity of the gingival extension, Provide a gingival extension of the healing body.

[0013] In another aspect, the present invention provides a base for a healing body for attachment to an implant, comprising: the base comprises a body with a through cavity extending in a coronal-apical direction, the body having an outer surface with a circular annulus with a coronally facing annular axial abutment surface, the circular annulus dividing the base into an apical portion and a coronal portion for attachment to the implant, the through cavity having a larger cross-sectional diameter at its coronal end than at its apical end, an inner surface of the through cavity transitioning in the apical portion of the base from the cross-sectional diameter at the coronal end to the cross-sectional diameter at the apical end by a transition section; - said coronal portion having a tubular shape and a planar coronal abutment surface at a coronal end of said coronal portion; - at least one identification relief directed radially inwards is arranged on the outer circumferential surface of the coronal end of said coronal portion; - an anti-rotation projection is formed on the outer peripheral surface of the apical end of the coronal portion, the anti-rotation projection being directed radially outward; - the through-cavity is provided with an internal coronal thread at the coronal end of the coronal portion; Provides a base for the healing body.

[0014] In another aspect, the present invention provides a healing body assembly, comprising: - the base of the healing body as defined above; - the gingival extension as defined above; - a base screw; - Healing body plugs and Equipped with the apical section of the through-cavity of the gingival extension is externally placed over the coronal portion of the base such that the apical abutment surface of the gingival extension abuts the axial abutment surface of the base, the anti-rotation protrusion of the base fits into the apical anti-rotation recess of the gingival extension, and the through-cavity of the gingival extension 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-bore of the healing body assembly so that a bearing surface of the head of the base screw rests on the transition section of the through-bore 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 part of the through-bore of the base to fix the healing body assembly to the implant by the external thread at the apical end of the shank of the base screw; the healing body plug is inserted into the common through-bore of the healing body assembly to secure the gingival extension to the base, and the external threads of the apical end of the shank of the plug are threaded into the internal coronal threads of the base so that the head of the plug rests on the coronal abutment surface of the gingival extension; A healing body assembly is provided.

[0015] In dental implant healing without immediate loading, implant plugs are used to prevent inappropriate bone growth and shape the bone around the implant, allowing for subsequent application of a healing body system without the need for further correction (removal) by grinding away the underlying bone. The implant plug is one-piece, rotationally symmetrical, and has a screw shape with a head and shank. The screw has an external thread at least at its apical end for attachment to the implant, preferably in the M1.4 to M2.0 range, more preferably M1.4, M1.6, M1.8, or M2.0 thread size. The shape of the implant plug at the apical portion of the head is tailored to the specific implant type and is preferably screwed in with a system driver. The implant plug is preferably made of metal, more preferably a titanium alloy, and most preferably a Ti6Al4V titanium alloy. Depending on the implant's insertion level below the bone level, the dentist selects an implant plug around which bone can grow and creates a clean opening above the implant level for inserting the base of the healing body. The crown height of the head of the implant plug 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 head of the implant plug at the coronal portion 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 base of the healing body is the basic support component of the healing body, resting on the implant and secured therein by a base screw (see below) passing through it (the shape of the base is similar to the "interface" type components commonly used in implant dentistry). The base may be made of any of a group of suitable materials, including plastics, ceramics, and metals, such as polyetheretherketone (PEEK), polyetherketoneketone, reinforced polymers reinforced with glass fiber, carbon fiber, 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. In the apical part, the base has a shape that allows a complete connection with the abutment (and sealing) profile of the implant, including the coupling of the anti-rotation element (the shape and dimensions of the apical part 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 attached implant, so there are variations in different sizes and types of bases for different types of implants and their size series. The base always has a fixed position relative to the implant and is fixed by anti-rotation elements present on both the implant and the base, preventing it from rotating relative to the implant after it is connected and screwed onto the base screw. The cross-section of the coronal portion of the base can preferably have a periphery in the shape of a circle, an ellipse, or an oval, more preferably a circle. The annular axial 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 axial abutment surface can preferably have the shape of a circle, an ellipse, or an oval, more preferably a circle. Preferably, the surface of the transition section of the through-bore of the base has the shape of a truncated cone surface.The through-hole of the base is preferably provided with an apical internal thread, preferably in the M1.4-M2.0 range, more preferably M1.4, M1.6, M1.8, or M2.0 size, on the apical side of the transition section, for threading the base screw and other screws of the system according to the present invention, such as the thread of the impression pin (see below), so that they do not spontaneously slip out of the base during handling. The coronal internal thread is preferably in the M2.0-M3.5 range, preferably M2.5 or M3.0 size, and serves to secure the supported components. The coronal portion of the base is universal for a particular series of healing body systems, allowing any gingival extension of this series to be placed on any base of this series. The number of identification reliefs is preferably 2-4, 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, in the case of three identification reliefs, the axis of the first relief forms a first angle, the axis of the second relief forms a second angle, the axis of the third relief forms a third angle, etc., with respect to the axis of the anti-rotation projection, the first angle preferably being between 0° and 350°, for example 73°, the second angle preferably being between 5° and 355°, for example 143°, 153°, 163° or 173°, and the third angle preferably being between 10° and 360°, for example 287°. The axes of the individual reliefs preferably form angles with each other of at least 5°, more preferably at least 70°. In the case of a small base with an oval or elliptical coronal portion (e.g. for SC implants manufactured by Straumann Holding AG, Basel, Switzerland), it is preferred that two identification reliefs are distributed along the periphery of the coronal end, the axis of the first relief forming a first angle and the axis of the second relief forming a second angle with respect to the axis of the anti-rotation projection, the first angle being preferably between -45° and +45°, more preferably 0°, and the second angle being preferably between 135° and 225°, for example 175°, 180° or 185°.Preferably, the outer portion of the at least one identification relief lies on an imaginary circle (or a corresponding imaginary oval or ellipse) 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 protrusions can have any suitable cross-sectional shape, such as a dashed or curved line, but preferably have a rounded shape, and most preferably have an arc shape. The base of each type and size of implant has multiple, preferably at least two, apical heights to account for different implant insertion depths relative to the level of the bone margin. 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 or maximum outer cross-sectional dimension preferably of 2.0 to 4.5 mm, more preferably 2.1, 3.3, 4.0, or 4.5 mm. The annular shaft abutment surface preferably has a maximum outer dimension of 2.9 to 9 mm, more preferably is circular with an outer diameter of 4.1 mm.

[0017] The role of the gingival extension is to shape the soft tissue above the implant. The gingival extension may be made of any of a group of suitable materials, including plastics, ceramics, and metals, such as polyetheretherketone, polyetherketoneketone, reinforced polymers reinforced with glass fiber, carbon fiber, 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 extension can be positioned on any base within a series of healing body systems. The through-hole of the gingival extension can be preferably circular, elliptical, or oval, with circular being more preferred. The through-cavity of the gingival extension is preferably unthreaded, and the internal dimensions of the through-cavity in the apical section are such that the apical section can be placed on the coronal portion of the base and therefore correspond to the external shape and size of the coronal portion of the base, with the dimensions in a cross section perpendicular to the longitudinal axis of the gingival extension preferably ranging from 2.02 mm to 4.52 mm, most preferably 2.12 mm, 3.32 mm, 4.02 mm, or 4.52 mm. The coronal section of the through-cavity of the gingival extension preferably has a circular, elliptical, or oblong internal shape and is shaped to correspond to the external diameter of the head of the healing body plug so that the healing body plug can always be inserted into the coronal section, with the dimensions in a cross section perpendicular to the longitudinal axis of the gingival extension most preferably ranging from 3.1 mm to 5.5 mm, preferably 3.12 mm, 3.32 mm, 4.02 mm, 4.52 mm, or 5.22 mm in diameter, most preferably 3.32 mm. On the side of the gingival extension away from the through-cavity, the anti-rotation recess can have any suitable cross-sectional shape, for example a dashed or curved shape, but preferably has a rounded shape, and most preferably has an arc shape. Depending on the thickness of the soft tissue at the implant site, the build height of each type of gingival extension will vary.The height of the gingival extension is related to the selected height of the base of the healing body, and the combination of both components is determined by the dentist. The overall height of the gingival extension 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 extension has a fixed position relative to the base, and therefore to the implant, determined by the anti-rotation protrusion on the base and the complementary apical anti-rotation recess on the gingival extension. This is necessary because the gingival extension has an asymmetric shape; it is always designed for the specific position of the implant in the jaw arch; the desired shape and aesthetics of the healed soft tissue are guaranteed only by the correct rotational position of the gingival extension in the direction of the vestibular orifice. Therefore, during implantation of the dental implant, the subsequent application of the healing body system must already be taken into consideration, and the correct rotational position of the implant, and therefore of the entire subsequent assembly of the healing body, must always be guaranteed. This is achieved during implantation (screw-into-bone) by using a control device—a control pin (see below) to which the gingival extension is attached—which allows for very precise positioning of the implant. There are various gingival extensions (shapes and sizes) that function depending on the specific location in the jaw and the soft tissue height. While the top surface shape of the gingival extension is derived from the top surface shape of each tooth, the gingival extension at the coronal end preferably retains this shape for a distance of 2 mm, after which the gingival extension gradually narrows to the shape and size of the base annulus, preferably its diameter. Thus, at the apical end, the gingival extension preferably has an outer dimension ranging from 2.9 mm to 9 mm, and more preferably a circular shape with a diameter of 4.1 mm.

[0018] The base screw, intended to secure 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 titanium alloy, and most preferably Ti6Al4V titanium alloy. Its external threads preferably range in size from M1.4 to M2.0, more preferably M1.4, M1.6, M1.8, or M2.0. Its height preferably ranges from 5.0 to 15.0 mm, more preferably 6.7, 7.0, or 8 mm. The outer diameter of the head at the coronal end preferably ranges from 1.9 to 2.5 mm, preferably 2.1, 2.2, or 2.4 mm.

[0019] The healing body plug is a threaded component that serves two functions: it draws the gingival extension toward the base of the healing body, while simultaneously closing the internal opening of the gingival extension from the occlusal side toward the coronal-apical direction, thereby preventing the intrusion of dirt into the internal space of the implant / base / gingival extension / plug assembly. It is a universal component in all assemblies of a given series of healing body assemblies, preferably in all assemblies of multiple series. By threading the plug into the coronal internal threads of the base, a fixed connection of the implant / healing body base / gingival extension set is created as a functional assembly of the components. The implant body plug is preferably made of metal, more preferably titanium alloy, and most preferably Ti6Al4V titanium alloy. The external thread preferably has a size ranging from 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, and 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 comprising: the dental prosthesis has the shape of a hollow cylinder with a through-bore extending in a coronal-apical direction, the through-bore having a larger cross-sectional diameter at its coronal end than at its apical end, the inner surface of the through-bore transitioning from the cross-sectional diameter at the coronal end to the cross-sectional diameter at the apical end by a transition section, fixing means for fixing impression material being arranged on the outer surface of the coronal end of the cylinder, a threaded section formed at the apical end having an external thread and an outer diameter smaller than the cylinder, while a coronal bearing surface facing apically is formed at the transition of the outer surface between the threaded section and the cylinder, Provide impression pins.

[0021] In another aspect, the present invention provides an impression pin assembly comprising: - the base of the healing body as defined above; - the gingival extension as defined above; - an impression pin as defined above; - impression pin screws; Equipped with the apical section of the through-cavity of the gingival extension is externally placed over the coronal portion of the base such that the apical abutment surface of the gingival extension abuts the axial abutment surface of the base, the anti-rotation protrusion of the base fits into the apical anti-rotation recess of the gingival extension, and the through-cavity of the gingival extension and the through-cavity of the base are coaxially connected to form a common through-cavity of a healing body assembly; an apical end of the impression pin is inserted into the common through-bore of the healing body assembly such that the threaded section of the impression pin is threaded into the coronal internal threads of the base, the coronal abutment surface of the impression pin abuts the coronal abutment surface of the gingival extension, and the through-bore of the impression pin, the through-bore of the gingival extension, and the through-bore of the base are coaxially connected to form a common through-bore of the impression pin assembly; the impression pin screw is inserted into the common through bore of the impression pin assembly such that a bearing surface of a head of the impression pin screw rests on the transition section of the through bore of the impression pin to secure the impression pin assembly to the implant by external threads at the apical end of the shank of the impression pin screw; An impression pin assembly is provided.

[0022] The impression pin is a versatile component in one series of implant body systems, used to transfer the position of the implant to the impression when using an analog impression technique with impression material. The impression pin may be made of any of a group of suitable materials, including plastics and metals, such as thermoplastic polymers, polyetheretherketone, polyetherketoneketone, reinforced polymers, such as those reinforced with glass fiber, carbon fiber, 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. Titanium or titanium alloys are more preferred, and Ti6Al4V titanium alloy is most preferred. For impressions using the open technique, a fixing means, preferably a rib or groove, is provided at the coronal end for secure fixation to the impression material. Preferably, the fixing means is formed by a series of projections and grooves perpendicular to the longitudinal axis of the impression pin, with the grooves and faces arranged parallel to this axis. The apical end is intended to be inserted into the through-cavity of the gingival extension and screwed onto the coronal internal threads of the base. The external threads of the threaded section have a size ranging from M2.0 to M3.5, preferably M2.5 or M3.0. In a preferred embodiment, the barrel does 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, so that a wider section having a larger outer diameter than the barrel of the impression pin is formed coronally from the threaded section of the apical end of the impression pin.More preferably, a middle section having an outer diameter smaller than that of the wide section and larger than that of the threaded section is disposed at the apical end of the impression pin between the wide section and the threaded section, whereby a coronal abutment surface is formed at the outer surface transition between the middle section and the wide section, and an apical bearing surface is formed at the outer surface transition between the middle section and the threaded section, facing apically, which opposes the coronal abutment surface of the base of the impression pin assembly when the impression pin is threaded. The maximum outer diameter of the cylinder at the apical end of the impression pin, or the outer diameter of the wide section, is such that the apical end of the impression pin can be inserted into the coronal section of the through-cavity of the gingival extension, and preferably has an outer diameter 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 midsection, which allows insertion into the apical portion of the through-cavity of the gingival extension, 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 overall 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, allowing an impression pin screw to be inserted into the cavity to secure the base / gingival extension / impression pin assembly to the implant. The internal cross-sectional diameter of the through-cavity coronally from the transition section 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 driver. The impression pin screw is preferably made of metal, more preferably titanium alloy, and most preferably Ti6Al4V titanium alloy.The impression pin threads preferably have external metric threads 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 head, measured coronally from the upper bearing surface, preferably ranges from 1.9 mm to 2.5 mm, more preferably 2.1 mm, 2.2 mm, or 2.4 mm. The height preferably ranges from 20.0 mm to 35.0 mm, more preferably 26 mm. When using impression pins, the entire assembly is left in the impression to record the exact shape of the soft tissue when casting the stone model. After the impression is made, the same combination of base / gingival extension components that the dentist left in the impression is inserted into the implant.

[0023] In another aspect, the present invention provides a control pin for controlling the position of an implant, comprising: a circular ring on its outer surface with a coronally facing annular axial abutment surface, said circular ring dividing said control pin into an apical portion for attachment to said implant and a coronal portion having a cylindrical shape, said anti-rotation projections facing radially outwardly being disposed on the outer periphery of the apical end of said coronal portion, and said control element being disposed on the coronal end of said coronal portion; Provides control pins.

[0024] In another aspect, the present invention provides a control pin assembly comprising: - a control pin as defined above; - the gingival extension as defined above; Equipped with the apical section of the through-cavity of the gingival extension is externally placed over the coronal portion of the control pin such that the apical abutment surface of the gingival extension abuts the axial abutment surface of the control pin and the anti-rotation protrusion of the control pin fits into the apical anti-rotation recess of the gingival extension. A control pin assembly is provided.

[0025] The control pin is a component necessary for the correct placement of the implant during implantation. The gingival extension must be precisely positioned within the jaw to perform its function, and therefore must be maintained in the correct position during implantation (when the implant is screwed in). This can usually be roughly achieved using marks on the implant's original transmission component, but the use of a control pin allows for more precise positioning. The dentist places the selected gingival extension (according to the position of the implant relative to the jaw) on the control pin and inserts the control pin into the implant fixture. This allows the current rotational position of the implant or gingival extension, respectively, to be confirmed. If it is subsequently decided to change the position of the implant, a control tool (preferably a ratchet or suitable tightening wrench) is placed on the control element of the control pin (preferably polygonal, more preferably triangular-octagonal, even more preferably hexagonal-octagonal, and most preferably octagonal) to rotate the implant to the desired position. The control pin may be made of any of a group of suitable materials, including metals such as aluminum alloys containing one or more elements, such as copper, magnesium, silicon, nickel, zinc, manganese, or titanium; cobalt and chromium alloys; and austenitic stainless steels. Titanium or titanium alloys are more preferred, and Ti6Al4V titanium alloy is most preferred. The apical portion of the control pin, like the apical portion of the base, has a shape compatible with the implant, as described above. The coronal portion of the control pin preferably has a circular, elliptical, or oblong cross-section, more preferably a circular cross-section. The control pin cannot rotate relative to the implant and always maintains a fixed position relative to the implant, due to the anti-rotation elements present on both the implant and the control pin. The anti-rotation projection is similar to the anti-rotation projection on the base and is complementary in shape to the apical anti-rotation recess on the gingival extension. On the side of the control pin away from the circumferential surface of the coronal portion, the anti-rotation protrusion can have any suitable cross-sectional shape, such as a dashed or curved shape, but preferably has a rounded shape, and most preferably has an arc shape.The annular axial abutment surface 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 annular axial abutment surface can preferably have a circular, elliptical, or oval shape, more preferably a circle. The outer shape and dimensions of the coronal portion are such that a gingival extension can be placed thereon. Preferably, the outer dimensions or diameter, at least in the apical section of the coronal portion (which will be at the apical portion of the through-cavity of the gingival extension after insertion), correspond to the inner dimensions or diameter of the apical section of the through-cavity of the gingival extension, 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. The height of the control pin is preferably in the range of 8.0 mm to 35.0 mm, more preferably 16.0 mm or 17.3 mm.

[0027] In another aspect, the present invention provides a scanner assembly comprising: - the base of the healing body as defined above; - the gingival extension as defined above; - a base screw; - a scanning body as defined above; - a scanning screw; Equipped with the apical section of the through-cavity of the gingival extension is externally placed over the coronal portion of the base such that the apical abutment surface of the gingival extension abuts the axial abutment surface of the base, the anti-rotation protrusion of the base fits into the apical anti-rotation recess of the gingival extension, and the through-cavity of the gingival extension and the through-cavity of the base are coaxially connected to form a common through-cavity of a healing body assembly; the base screw is inserted into the common through-bore of the healing body assembly so that a bearing surface of the head of the base screw rests on the transition section of the through-bore of the base and the head of the base screw does not interfere with the space of the coronal inner thread at the coronal end of the coronal part of the through-bore of the base to fix the healing body assembly to the implant by the outer thread at the apical end of the shank of the base screw; the apical end of the scanning body is inserted into the common through-cavity of the healing body assembly such that the anti-rotation protrusion fits into the coronal anti-rotation recess of the gingival extension, the apical abutment surface abuts the coronal abutment surface of the base, the at least one identification protrusion fits into the at least one identification relief of the base, and the through-cavity of the scanning body, the through-cavity of the gingival extension, and the through-cavity of the base are coaxially connected to form a common through-cavity of the scanning body assembly; the scanner screw is inserted into the common through-bore of the scanner assembly to secure the scanner and the gingival extension to the base, and the external threads on the apical end of the shank of the scanner screw are threaded into the coronal internal threads of the base so that the bearing surface of the head of the scanner screw rests on the internal bearing surface of the scanner; A scanning body assembly is provided.

[0028] The scanner is a component used to digitally create an impression of the implant position. The scanner can be manufactured as a single piece using one of the materials listed below for the body or head, but is preferably manufactured as a two-piece piece using a combination of two materials, i.e., the body is made from one material and the head is made from another material. The body of the scanner is inserted into the opening in the gingival extension and fits into a relief at the coronal end of the base of the healing body. From the standpoint of durability and functional accuracy, it is preferably made from one of a group of suitable materials, including metals such as aluminum alloys containing one or more elements, such as copper, magnesium, silicon, nickel, zinc, manganese, or titanium, cobalt and chromium alloys, zirconium dioxide, and austenitic stainless steel; titanium or a titanium alloy is preferred, and Ti6Al4V titanium alloy is most preferred. The head of the scanning body is preferably made of one of a group of suitable materials, including plastics such as thermoplastic polymers, polyetheretherketone, polyetherketoneketone, and reinforced polymers reinforced with glass fiber, carbon fiber, and / or ceramic particles, for trouble-free scanning using an intraoral scanner (IOS). The scanning body has a circular, elliptical, or oval cross-sectional periphery, more preferably a circular cross-sectional periphery. The scanning recess (preferably a bevel in the shape of a circular segment) allows the scanner to identify the position and rotation of the scanning body. The head is preferably pressed or glued to the body. The coronal end of the body where the head is attached preferably has a smaller outer diameter than the portion of the body continuing apically from the head. Even more preferably, there is a recess on the outer surface of the coronal end of the metal part corresponding to the scanning recess, which serves as an anti-rotation element for properly connecting the two parts. The head preferably has an outer diameter ranging from 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 through-cavity of the gingival extension, more preferably in the range of 5 to 25 mm, and most preferably 10.53 mm.In a preferred embodiment, the cylinder of the body has a wider cross section (i.e., in the case of a circular cross section, a larger outer diameter) along at least a portion of its outer periphery from the head of the coronal portion toward the apex than the apical end of the body, thereby forming an apical narrow section at the apical end of the body and a coronal abutment surface at the transition of the outer surface between the apical narrow section and the remainder of the body that faces the coronal abutment surface of the gingival extension after fixation of the scanner. In this embodiment of a scanner with an elliptical or oval cross section, the widened section is preferably formed on both sides of the short axis of symmetry of the ellipse (or the minor axis of the ellipse), and in the case of a scanner with a circular cross section, the widened section is preferably formed around the entire periphery, and the coronal abutment surface is interrupted by an anti-rotation protrusion with a larger outer diameter that extends radially to the level of the outer surface of the scanner. The outer side of the at least one identification protrusion facing radially outward and the inner side of the anti-rotation protrusion facing radially into the through-hole of the scanning body preferably lie on an imaginary circle having the outer diameter of the main body of the scanning body (or on a corresponding imaginary ellipse or imaginary oval), or, in the preferred embodiment described above, on an imaginary circle having the diameter of the apical narrow section (or on a corresponding imaginary ellipse or imaginary oval). The inner side of the at least one identification protrusion and the outer side of the anti-rotation protrusion of the scanning body can 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 protrusions of the scanning body are defined in the same way as the identification relief of the base. In a preferred embodiment, the anti-rotation protrusion extends apically beyond the apical abutment surface by a distance shorter than the at least one identification protrusion. The screw of the scanning body can be inserted into the through-hole of the scanning body, thereby firmly fixing the scanning body to the coronal internal screw of the base. The screws of the scanning body are preferably tightened with a system driver and are preferably made of metal, more preferably titanium alloy, and most preferably Ti6Al4V titanium alloy.The external thread preferably has a size ranging from M2.0 to M3.5, more preferably M2.5 or M3.0. The inner bearing surface for abutting the head of the scanning body screw is preferably formed in the coronal portion of the scanning body's through-hole, but can also be formed by the surface of the scanning body's coronal end. The inner bearing surface is preferably formed so that the scanning body's through-hole narrows apically from the inner bearing surface or widens coronally from the inner bearing surface, and is formed at the transition between the narrow and wide sections of the inner surface of the through-hole. The inner bearing surface preferably extends 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 a thread ranging from M2.0 to M3.5, more preferably M2.5 or M3.0, from the inner bearing surface apically, and the scanning body screw is preferably screwed in to prevent it from spontaneously slipping out of the scanning body during handling. As already explained above, the base and the scanning body of the healing body each have a unique combination of identification and locking from the identification relief and the identification protrusion, so that a single scanning body corresponds to each type of base. The identification protrusions of the scanning body have a shape complementary to the identification relief of the base, the anti-rotation protrusions of the scanning body have a shape complementary to the coronal anti-rotation recesses of the gingival extension, and the distribution (and number) of the anti-rotation protrusions and identification protrusions along the periphery of the apical end of the scanning body corresponds to the distribution (and number) of the anti-rotation protrusions and identification reliefs along the periphery of the coronal end of the base, as explained above. Thanks to this connection, in addition to its main function (i.e., accurate scanning of the implant position), the scanning body also serves as an identifier for the used base. This unique feature can be used so that during scanning, the dentist does not need to remove all the components above the implant to visually detect its type, but simply loosens the healing body plug and inserts the scanning body of the expected type into the cavity. If it fits into the lock that defines the correct position, it can then be fixed with a screw inside the body.If the type of scan body is selected incorrectly, the body cannot be positioned correctly, cannot be secured with a screw, and in the preferred circular embodiment, the body will also rotate within the gingival extension. Thus, once the dentist recognizes the incorrect selection, he or she selects another scan body from the limited set prepared for the procedure. This identification process makes it possible to determine both the type of base used and, crucially, the type of implant, thereby eliminating mistakes by the dentist when identifying the base or implant used.

[0029] In another aspect, the present invention provides a kit comprising: - The following components - the gingival extension defined above, - the base of the healing body as defined above, - the impression pin as defined above, - the control pins defined above, - the scanning body defined above, and at least one of - Optionally, by: - an implant plug for shaping bone tissue around said implant, said implant plug having the form of a screw with a head and a shank, said shank having an external thread at its apical end for attachment to said implant; - a base screw inserted into a common through-bore formed by the through-bore of the gingival extension and the through-bore of the base so that a bearing surface of the head of the base screw rests on the transition section of the through-bore of the base and the head of the base screw does not interfere with the space of the coronal inner thread at the coronal end of the coronal part of the through-bore of the base, in order to fix the gingival extension and the base to the implant by an outer thread at the apical end of the shank of the base screw; - a healing body plug, which is inserted into the common through-hole formed by the through-holes of the gingival extension and base assembly and the through-holes of the base assembly to fix the gingival extension to the base, and the external threads at the apical end of the shank of the plug are threaded into the coronal internal threads of the base so that the head of the plug rests on the coronal abutment surface of the gingival extension; - an impression pin screw inserted into a common through-bore formed by the through-bore of the impression pin, the through-bore of the gingival extension and the through-bore of the base so that a bearing surface of a head of the impression pin screw rests on the transition section of the through-bore of the impression pin, in order to fix the assembly of the impression pin, the gingival extension and the base to the implant by external threads at the apical end of the shank of the impression pin screw; - a scanning body screw, which is inserted into a common through-bore formed by the through-bore of the scanning body, the through-bore of the gingival extension, and the through-bore of the base to fix the scanning body and the gingival extension to the base, and the external threads at the apical end of the shank of the scanning body screw are screwed into the coronal internal threads of the base so that a bearing surface of a head of the scanning body screw rests on the internal bearing surface of the scanning body; and at least one of A kit is provided, comprising:

[0030] Preferred kits according to the invention include various combinations of the components and means described above, optionally with handling aids for handling them, and optionally with tightening tools such as screwdrivers, ratchets, or wrenches. It will be clear to those skilled in the art that individual components, means, aids, and tools can be provided individually, in larger packages, and in assemblies. A preferred kit would include a complete series of systems according to the invention for a given implant system.

[0031] The heads of all of the above-mentioned screw components (i.e., screws and plugs) can be knurled along the periphery. The heads can be equipped with any element for a tightening 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., a square (Robertson), a hexagonal), a cavity in the shape of a multi-pointed star (e.g., a Torx hexagonal star), a special cavity (e.g., Unigrip type), a hexagonal cavity preferably sized 0.9 mm, 1.0 mm, 1.20 mm, 1.25 mm, or 1.4 mm, a Unigrip, or a Torx socket. Those skilled in the art will understand that it is most advantageous to provide a system element for a tightening tool on the heads of all screws in a system for a particular implant. The shanks of all of the above-described threaded components (i.e., screws and plugs) may be threaded along the entire elongation 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] All anti-rotation elements of a system according to the invention are preferably arranged one above the other. In elliptical or oval embodiments, the anti-rotation elements are preferably arranged at the apex of the longer axis of symmetry of the ellipse or at the apex of the longer axis of the oval.

[0033] The materials from which the components of the system according to the invention are made are preferably biocompatible.

[0034] As used herein, the term "apical" means toward the root of the tooth. As used herein, the term "coronal" means toward the crown of the tooth.

[0035] As used herein, the term "cross section" refers to a cross section perpendicular to the longitudinal axis (ie, an axis extending in a coronal-apical direction) of a given component or portion thereof.

[0036] Those 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, oval, etc., the component, element, part, or section is formed substantially in that shape, i.e., the shape may include deviations from that shape, such as widened or narrowed portions, protrusions, recesses, reliefs, or projections. Those skilled in the art will also understand that for parts that are inserted into one another, there must be a gap between the outer wall of the inserted inner part and the inner wall of the outer part, and that this gap, while expressed herein as a 0.02 mm larger dimension for the outer part, may in practice include reasonable deviations from the stated dimensions.

[0037] As used herein, the term "system" (screws, drivers, elements, etc.) refers to components (auxiliaries, shapes) that are supplied (built) directly by the manufacturer of a particular dental implant and that are adapted 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 a patient's upper or lower jaw.

[0039] The term "universal" as used herein with respect to individual components of the systems of the present invention means that a given component is broadly applicable within a particular embodiment of a series of systems, i.e., an embodiment in which the dimensions of the cooperating portions of the components correspond to one another.

[0040] The healing body system is applicable to bone-level and tissue-level dental implants and all their dimensional versions. This requires that the healing body system exist in multiple shape and size series that contain individual components of the same functional type, but these components cannot be combined with each other across the individual series due to different sizes and shapes of transition and connecting elements. For multiple dimensional variations of one type of implant, a common series of the healing body system can preferably be defined such that some components within the series are specific to each size of implant, while other components are common (and thus considered generic within a particular series of the system).

[0041] The healing body system of the present invention is an innovative system of uniform components that makes the dentist's work easier, faster, and error-free. The system has been developed to be universal and therefore applicable to all implant systems. It has been developed to be easy to use when taking patient impressions using both analog (using impression material) and digital (using an intraoral scanner) methods.

[0042] The healing body system according to the present invention offers many advantages. - A composite system that contains everything a dentist needs to obtain an effective result (both the functional components and the auxiliaries necessary for the correct application of the individual components). - Its versatility allows it to be applied to almost all types and sizes of dental implants in use. - Covers commonly used transplant techniques. - Providing the dentist with the option to choose variables when different types of healing body bases can be combined into one type of implant and then different types of gingival extensions can be placed on these, while the connection between the base and the gingival extension is universal and the healing body plug is also universal. - Designed to eliminate user errors that can occur during the digital impression process using IOS, resulting in dentists working faster and more efficiently. - The bases and scanners have a unique combination of identification and locking mechanism, so that a single scanner is compatible with each type of base, eliminating errors when the dentist identifies the base or implant being used. - Each component can be provided with a readable marking with a catalogue code as well as a matrix / QR code readable by an intraoral scanning camera, so that when the dentist scans the scan body (recording the implant position), the gingival extension and the soft tissue surrounding the gingival extension in one go during the digital impression, all the necessary information about the type of component used (implant fixture, base and gingival extension) is automatically recorded. - Compatible with both analogue and digital impression types, the shape of the surrounding soft tissues of the body is always perfectly and accurately recorded, without deviations. - Thanks to the universal components, the system can also be used advantageously in combination with implant dentistry systems, saving treatment costs.

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