Description

Oral implant, connector, and oral implant component

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 4, 2023, with application number 202311132122.1 and invention name “A New Oral Implant”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application belongs to the field of oral technology, and specifically relates to an oral implant, a connector, and an oral implant component. Background Art

[0003] Oral implant restoration is a method of using oral implant restorations (or artificial implant roots) to replace missing natural tooth roots and install artificial crowns on them to restore the function and beauty of teeth. Usually, oral implants are connected to artificial crowns through connectors (here called restoration abutments). In oral implant restoration treatment, the most commonly used method of retaining and connecting oral implants and restoration abutments is screw retention, that is, using a screw to retain and connect the oral implant and restoration abutment. This method still has many problems in actual work:

[0004] 1. Loosening of the abutment screws: Occlusal forces are directed in all directions, and there will inevitably be a strong force in the direction of loosening the screws. The incidence of this problem increases significantly with the time the dental implant is in the mouth. Loosening of the abutment screws can cause occlusal disorders, tissue trauma and / or artificial crown fracture. In severe cases, it can also cause periodontal inflammation, bone tissue resorption, and even oral implant loss.

[0005] 2. Broken screws of the restoration abutment: Due to the structural limitations of the restoration abutment, the screws of the restoration abutment cannot be made too thick. Since the screws are the link between the oral implant and the restoration abutment, when the artificial crown often bears a large occlusal force, the incidence of broken screws of the restoration abutment is also high.

[0006] 3 Oral implants and restorative abutments are retained in place by screws applying pressure. The pressure is continuous and much greater than the force of orthodontic treatment, which may cause alveolar bone absorption.

[0007] 4 Due to the limitations of oral anatomy, the openings for the restoration abutment screws may appear in undesirable areas, such as the labial side of the anterior teeth, which greatly affects the aesthetics. Therefore, the artificial crown cannot be bonded to the restoration abutment during the extraoral production process, and can only be left to the doctor to bond in the mouth. In this way, the screw holes on the labial side of the artificial crown can be omitted, maintaining the integrity and aesthetics of the labial crown. However, this brings the following problems: (1) Since the artificial crown is bonded in the mouth, the field of vision and operating angle are limited. When cleaning the adhesive that overflows during the bonding process, there may be residue. Many current literatures point out that the residual adhesive may cause alveolar bone absorption. (2) Since the screw openings are covered when the artificial crown is bonded to the restoration abutment, when maintenance is required (for example, when the screws of the restoration abutment are found to be loose and need to be tightened again), the artificial crown must be destroyed.

[0008] 5 Since the artificial crown is bonded to the restoration base, it is a rigid connection; and the restoration base is connected to the oral implant by pressure, which is also a rigid connection; the oral implant and the alveolar bone are also rigidly connected. Therefore, it can be deduced from the above that the artificial crown and the alveolar bone are rigidly connected, but the natural tooth and the alveolar bone are elastically connected, with the periodontal ligament in the middle as a buffer, so the connection between the artificial crown and the alveolar does not conform to biological characteristics.

[0009] 6. The screws of the restoration base and their placement channels occupy a large space of the restoration base itself, which brings great difficulties to the design of other structures.

[0010] Since the screw-retained connection method between oral implants and restoration abutments has many disadvantages, there are also non-screw-retained designs, such as the Bicon implant series design, which knocks the restoration abutment into the oral implant through a 1.5° taper and uses the strong friction generated by extrusion to retain it. Although this design omits screws, the restoration abutment and the oral implant are not easy to disassemble due to the strong friction. Once there is a problem with the artificial crown or the restoration abutment, the conditions for repair will be lost.

Simultaneously, a first recess is provided on the sidewall of the first channel in the implant body. When the connector is in place in the implant body, the first recess cooperates with the sidewall of the connector to form a second channel, allowing the plug to be inserted into the second channel. The direction in which the plug enters and exits the second channel intersects the direction in which the connector enters and exits the first channel. In this way, the plug forms an undercut fixing structure between the connector and the implant body, thereby preventing the connector from being dislodged from the implant body and achieving a secure connection between the connector and the implant body.

[0037] With the oral implant structure of this application, since the oral implant and connector are not retained by pressure, the force applied to the alveolar bone is reduced when the connector is seated in the oral implant, thus reducing alveolar bone absorption. Furthermore, the location and structural design of the second channel are more flexible, facilitating installation and removal. Furthermore, the use of an undercut bolt fixation method increases the contact area between the sidewalls of the implant body and the connector, helping to disperse the local force applied to the oral implant, thereby reducing the jaw force per unit area of ​​the alveolar bone and protecting the alveolar bone.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

Throughout the description of this application, unless otherwise specified, "plurality" means two or more. Furthermore, "and / or" in the specification and claims refers to at least one of the connected entities, and the character " / " generally indicates an "or" relationship between the connected entities.

[0052] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0053] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0054] The oral implant, connector, and oral implant assembly provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0055] It is understandable that since there are so many problems with the method of fixing the oral implant 11 and the connector 40 with screws in the related art, changing this connection method becomes a better choice. At the same time, the method of fixing the oral implant 11 and the connector 40 with friction also has serious problems.

[0056] Therefore, based on the principle of undercut retention in the present application, an undercut is made in the hollow channel of the oral implant 11 by a component, the plug 14 , and the undercut is used to restrict the complete separation of the connector 40 from the oral implant 11 .

[0057] It should be noted that the connector 40 may include a repair abutment, a healing abutment, a transfer abutment, etc. Regardless of the structure of the connector 40, the retention connection method between the oral implant 11 and the connector 40 can be the same.

[0058] Specifically, as shown in Figures 1 to 3, the present application designs an oral implant 11, which includes an outer surface connected to the alveolar bone and an internal hollow channel connected to the connector 40. There are two seating channels in this hollow channel, which respectively accommodate the connector 40 and the plug body 14, and the directions of the two seating channels accommodating the connector 40 and the plug body 14 do not overlap at all.

[0059] Due to the limitations of the retention structure, to achieve a fully seated state, the order in which the connector 40 and the plug 14 fill the hollow channel of the oral implant 11 must be constant, i.e., the connector 40 is seated first, followed by the plug 14. In the fully seated state, the length of the seating path of the hollow channel of the oral implant 11 that accommodates the plug 14 is positively correlated with the retention strength of the plug 14 to the connector 40 within the hollow channel of the oral implant 11. Furthermore, the wall of the seating path within the hollow channel of the oral implant 11 that provides a positive correlation in retention strength is incomplete.

[0060] The retention strength referred to here refers to the ability of the plug 14 to restrain the connector 40 in the fully seated state, preventing it from separating from the oral implant 11 in the direction opposite to the seating path (i.e., the direction of the dislocation path). The plug 14 successfully creates an undercut within the incomplete seating path wall within the hollow passage of the oral implant 11, which houses the plug 14. This undercut then connects the connector 40 to the oral implant. This incomplete path wall also allows the plug 14 to successfully link its retention strength to the length of the undercut within the incomplete seating path.

[0061] At the same time, this design allows the connector 40 to achieve a rigid connection between them through close contact between its outer peripheral wall and the inner wall of the hollow channel inside the oral implant 11, realizing a function similar to a screw-retained connection or a friction-retained connection; it can also achieve a flexible connection by allowing the connector 40 to achieve non-close contact between its outer peripheral wall and the inner wall of the hollow channel inside the oral implant 11 (they can be completely filled with a layer of elastic material or just form a ring or multiple rings around the surface of the connector 40), so as to more realistically simulate the connection between natural teeth and alveolar bones.

[0062] A gasket made of elastic material may also be provided at the portion of the top of the oral implant 11 that contacts the connector 40 to close the micro gap.

[0063] All elastic materials can be made of biomedical polymer materials, such as polytetrafluoroethylene, silicone rubber and natural rubber.

[0064] The beneficial effects of the present application include: 1. Because the retention strength of the plug body 14 is positively correlated with the length of the undercut within the incomplete seating channel of the oral implant 11, as the length of the undercut increases, the retention strength also increases. Therefore, from another perspective, the plug body 14 can be made thinner; simply by lengthening the undercut, the same retention strength can be achieved, thus creating and / or increasing space for the design of other components. 2. Because the oral implant 11 and the connector 40 are not retained by pressure, the stress on the alveolar bone is reduced when the connector 40 is fully seated within the hollow channel of the oral implant 11, reducing alveolar bone absorption. 3. Because the angle of the seating channel of the plug body 14 can be designed to be very oblique, this allows for the opening of most implant restorations to be located on the lingual side, facilitating disassembly, i.e., easier repair and maintenance. This also avoids the problem of adhesive overflow and difficulty in thorough cleaning when the opening is located on the labial side, which would require the doctor to bond the artificial crown intraorally. 4. Because the inner wall of the hollow channel of the oral implant 11 can maximize contact with the sidewalls of the restoration abutment, this reduces jaw force per unit area and protects the alveolar bone. 5. Because it mimics the connection between natural teeth and alveolar bone, it is more biologically compatible. 6. Compared with current technical solutions, it reduces or even eliminates implant complications, simplifies the operation, and thus reduces implant costs, creating favorable conditions for implant treatment to be included in national health insurance.

[0065] In some embodiments, referring to FIG1 , FIG1 shows a cross-sectional schematic diagram of the hollow channel of the oral implant 11 after the connector 40 is first fully positioned along the positioning guide surface 13 (i.e., the plane side wall 112 described later), and then the plug body 14 is fully positioned. The connector 40 is configured as a first restoration base 12. As can be seen from FIG1 , the channel wall accommodating the plug body 14 is composed of the inner wall 15 of the hollow channel of the oral implant and the side wall 16 of the first restoration base. A first additional screw channel 17 (i.e., the threaded hole 130 described later) is provided next to the plug body 14 to assist the plug body 14 in being fully positioned by providing screw retention between the connector 40 and the oral implant 11, and to release the screw retention between the connector 40 and the oral implant 11 after completing the task of assisting the positioning.

[0066] In some embodiments, referring to FIG2 , FIG2 shows a side view of the hollow channel of the oral implant 11 after the first repair base 12 is completely positioned along the seating path. FIG2 shows that there is an elastic sealing ring 21 at the connection between the first repair base 12 and the oral implant 11, which serves to seal the micro-gap between the first repair base 12 and the oral implant 11 (if the manufacturing is sufficiently precise, the elastic sealing ring 21 may not be required). FIG2 also shows that the seating direction (or dislocation direction) of the first repair base 12 does not overlap with the seating direction (or dislocation direction) of the plug body in the hollow channel of the oral implant 11. The plug body can slide into place in the first plug body seating path 22 (also known as the second channel 120 described later), or it can be rotated into place in the form of a screw thread. A screw-retained cap can also be provided at the opening of the seating path to seal the hole. A first additional screw channel 17 is located adjacent to the first plug-in seating channel. This channel assists in achieving full seating of the plug by providing screw retention between the connector 40 and the oral implant 11. Once the screw retention is complete, the connector 40 and the oral implant 11 are released. A second additional screw channel 23 is located at the bottom of the hollow channel of the oral implant 11 to screw-retain the healing abutment and transfer abutment.

[0067] In some embodiments, referring to FIG. 3 , FIG. 3 shows a schematic side view of the hollow channel of the oral implant 11 after the second restoration abutment 31 has been fully seated along the seating path. The connector 40 is configured as the second restoration abutment 31. FIG. 3 shows that an elastic material layer 32 is provided at the upper opening of the restoration abutment and on the sidewalls contacting the hollow channel wall of the oral implant 11. This layer serves to close the micro-gap between the restoration abutment and the oral implant 11 and to cushion the impact of jaw forces on the oral implant 11. It can also be seen that the seating direction (or dislocation direction) of the second restoration abutment 31 does not overlap with the seating direction (or dislocation direction) of the plug within the second bolt seating path 33 (also referred to as the second channel 120 described below) within the hollow channel of the oral implant 11. The plug can slide into place within the second bolt seating path 33 or rotate into place using a screw thread. A screw-retained cap can also be provided at the opening of the second bolt seating path 33 to seal the hole. A third additional screw channel 34 (also referred to as a threaded hole 130, described below) is located adjacent to the second bolt-positioning channel 33. This provides screw retention between the connector 40 and the oral implant 11 to assist in achieving full positioning of the bolt. After completing the task of assisting positioning, the screw retention between the connector 40 and the oral implant 11 is released. A second additional screw channel 23 is located at the bottom of the hollow channel of the oral implant 11 for screw-retaining the healing abutment and transfer abutment.

[0068] Optionally, as shown in Figures 1 to 5, an embodiment of the present application discloses an oral implant 11, which includes: an implant body 11a, a first channel 110 for accommodating a connector 40 is provided on the implant body 11a, and the direction in which the connector 40 enters and exits the first channel 110 is a first direction X; wherein, a first recessed portion 121 is provided on the side wall of the first channel 110, and the first recessed portion 121 is used to cooperate with the connector 40 to form a second channel 120 for accommodating a plug body 14, so as to fix the connector 40 and the implant body 11a through the plug body 14, and the direction in which the plug body 14 enters and exits the second channel 120 is a second direction Y, and the second direction Y intersects with the first direction X.

[0069] In the embodiment of the present application, a first channel 110 is provided in the implant body 11a so that the connector 40 can be installed in the first channel 110. At the same time, a first recessed portion 121 is provided on the sidewall of the first channel 110 in the implant body 11a. When the connector 40 is in place in the implant body 11a, the first recessed portion 121 cooperates with the sidewall of the connector 40 to form a second channel 120, so that the plug 14 can be inserted into the second channel 120, and the direction in which the plug 14 enters and exits the second channel 120 intersects the direction in which the connector 40 enters and exits the first channel 110. In this way, the plug 14 can form an undercut fixing structure between the connector 40 and the implant body 11a, thereby preventing the connector 40 from falling out of the implant body 11a and achieving a secure connection between the connector 40 and the implant body 11a.

[0070] With the oral implant 11 structure of the present application, since the oral implant 11 and the connector 40 are not retained by pressure, the force applied to the alveolar bone when the connector 40 is seated in the oral implant 11 is reduced, thus minimizing alveolar bone absorption. Furthermore, the position and structural design of the second channel 120 are more flexible, facilitating actual installation and removal. Furthermore, the undercut fixing method of the bolt body 14 increases the contact area between the sidewalls of the implant body 11a and the sidewalls of the connector 40, helping to disperse the local force applied to the oral implant 11. This, in turn, reduces the jaw force per unit area of ​​the alveolar bone, thereby protecting the alveolar bone.

[0071] It should be noted that the intersection of the first direction X and the second direction Y means that the first direction X and the second direction Y are not parallel or coincident, or the angle between the first direction X and the second direction Y is not zero.

[0072] Specifically, a first recessed portion 121 is provided in the inner wall of the first channel 110 in the implant body 11a. When the connector 40 is installed in the first channel 110, the first recessed portion 121 cooperates with the connector 40 to form a second channel 120 for seating the plug 14. When the plug 14 is seated in the first channel 110, it is at least partially located within the first recessed portion 121. In other words, the plug 14 is at least partially embedded in the implant body 11a, forming an undercut fixing structure. Accordingly, a recessed structure or hole structure can also be provided in the connector 40 to allow the plug 14 to at least partially embed in the connector 40, thereby also forming an undercut fixing structure in the connector 40.

[0073] At the same time, by setting the direction of the plug body 14 entering and exiting the second channel 120 (that is, the second direction Y) to intersect with the direction of the connector 40 entering and exiting the first channel 110 (that is, the first direction X), the plug body 14 can be used to limit the connector 40 from escaping from the implant body 11a, thereby achieving the connection and fixation of the connector 40 and the oral implant 11.

[0074] In some embodiments, the first channel 110 and the second channel 120 can be set to extend along a straight line or a curve, which is not limited here. The structure of the bolt body 14 is adapted to the structure of the second channel 120, and the connector 40 is adapted to the structure of the first channel 110.

[0075] As shown in Figures 7 and 8, the direction in which the bolt body 14 enters and exits the second channel 120 (i.e., the second direction Y) can be determined according to the following method: first, a target point O is taken on the bolt body 14, and the position of the target point O when the bolt body 14 just enters the second channel 120 is recorded as the first position point A; when the bolt body 14 completely enters the second channel 120 and is in a fully positioned state, the position of the target point O is recorded as the second position point B. The direction of the motion trajectory line of the target point O between the first position A and the second position B is the direction in which the bolt body 14 enters and exits the second channel 120, that is, the second direction Y.

[0076] Accordingly, the method for determining the direction (ie, the first direction X) in which the connector 40 enters and exits the first channel 110 can be determined by referring to the method for determining the second direction Y, which will not be described in detail herein.

[0077] Furthermore, the motion trajectories of the connector 40 entering and exiting the first channel 110 and the bolt 14 entering and exiting the second channel 120 are determined according to the above method. The motion trajectory of the connector 40 entering and exiting the first channel 110 is defined as the first trajectory, and the motion trajectory of the bolt 14 entering and exiting the second channel 120 is defined as the second trajectory. If both the first and second trajectories are straight lines, the first direction X and the second direction Y can be considered to intersect as long as the first and second trajectories are not parallel or overlap.

[0078] Alternatively, when both the first trajectory line and the second trajectory line are curves (eg, arcs), the first direction X and the second direction Y may be considered to intersect as long as the curved surface passing through the first trajectory line and the curved surface passing through the second trajectory line are not parallel or overlapped.

[0079] Alternatively, when one of the first trajectory line and the second trajectory line is a straight line and the other is a curve, it is considered that the first direction X and the second direction Y intersect.

[0080] It should be noted that the specific method for determining the intersection of the first direction X and the second direction Y is not limited to the method in the above embodiment, and those skilled in the art can flexibly set it according to actual conditions.

[0081] It can be understood that the fully seated state means that the connector 40 is in place in the first channel 110 of the oral implant 11, and the plug body 14 is in place in the second channel 120, and an inverted concave retention structure is formed by the plug body 14 and the second channel 120, so that the oral implant 11, the connector 40 and the plug body 14 are combined with each other to achieve a state in which the plug body 14 and the connector 40 cannot fall out of the oral implant 11 at the same time.

[0082] The undercut retention structure is a structure in which recessed structures are provided in the connector 40 and the oral implant 11, respectively, so that the plug 14 is at least partially embedded in the recessed structures to provide a limiting and fixing function. The undercut retention structure is formed between the connector 40 and the oral implant 11 by the cooperation between the plug 14 and the second channel 120. At the same time, because the dislocation direction of the plug 14 from the second channel 120 is different from the dislocation direction of the connector 40 from the first channel 110, the plug 14 and the connector 40 are restricted from being dislodged from the oral implant 11 at the same time, thereby achieving a fixed connection between the connector 40 and the oral implant 11.

[0083] It should be noted that the above-mentioned recessed structure can be a groove structure or a hole structure provided on the side wall of the connector 40 and / or the oral implant 11, and the recessed structure constitutes a part of the second channel 120, so that after the plug body 14 is fully in place in the second channel 120, a part of the plug body 14 can be embedded in the connector 40, and at the same time another part of the plug body 14 is embedded in the oral implant 11, thereby realizing the limited fixation between the connector 40 and the oral implant 11.

[0084] In some embodiments, in addition to the second channel 120 formed between the implant body 11a and the connector 40, other channel structures may be provided. For example, an extension channel may be provided at at least one end of the second channel 120 along the extension direction of the second channel 120. The extension channel communicates with the second channel 120 to form a channel structure for installing the plug body 14. The extension channel can be used to assist in the placement or dislocation of the plug body 14. The structure and extension direction of the extension channel in the embodiments of the present application may be the same as or different from the second channel 120. This can be flexibly configured according to actual conditions and is not limited here.

[0085] In some embodiments, the shape of the first channel 110 provided in the implant body 11a can be cylindrical, conical, polyhedral or other irregular shapes. The shape of the first channel 110 can be flexibly set according to actual application conditions.

[0086] As shown in FIG3 , when the first channel 110 is a cylindrical channel, the connector 40 enters and exits the first channel 110 along a single direction, i.e., the axial direction of the cylindrical channel is the first direction X. Correspondingly, the direction in which the bolt body 14 enters and exits the second channel 120 (i.e., the second direction Y) intersects with the axial direction of the cylindrical channel (i.e., the first direction X).

[0087] Alternatively, as shown in FIG2 , the first channel 110 has an opening and a bottom facing each other, and the cross-sectional area of ​​the first channel 110 near the opening is larger than the cross-sectional area near the bottom, that is, the first channel 110 has a structure with a larger opening and a smaller bottom, such as a conical or quasi-conical shape. In this case, the connector 40 can enter and exit the first channel 110 in multiple directions. The first direction X can be along the axis of the first channel 110 (i.e., X1 in FIG2 ), along a tangent to the sidewall of the first channel 110 (i.e., X2 in FIG2 ), or any direction between the axis of the first channel 110 and a tangent to the sidewall of the first channel 110.

[0088] That is, in this case, the connector 40 can enter and exit the first channel 110 in multiple directions (i.e., the first direction X). Furthermore, the direction in which the bolt 14 enters and exits the second channel 120 (i.e., the second direction Y) is configured to intersect any of the first directions X, thereby preventing the bolt 14 from escaping from the second channel 120 in the same direction as the connector 40 from escaping from the first channel 110. In this way, regardless of the direction in which the connector 40 escapes from the first channel 110, it will be restricted by the bolt 14, ensuring that the bolt 14 provides a comprehensive positional fixation for the connector 40 and the implant body 11a.

[0089] In some embodiments, the shape of the second channel 120 formed by the first recessed portion 121 and the connector 40 may also be cylindrical, conical, polyhedral or other irregular shapes. The structural shape of the second channel 120 may be flexibly set according to actual application conditions.

[0090] Based on the different shapes of the second channel 120, the direction in which the plug body 14 enters and exits the second channel 120 (i.e., the second direction Y) may include multiple directions. For example, when the second channel 120 is cylindrical, the axial direction of the cylindrical channel is the second direction Y. When the second channel 120 is conical, the second direction Y may be along the axial direction of the conical channel, along the tangent line of the sidewall of the conical channel, or any direction between the axial direction and the tangent line of the sidewall of the conical channel.

[0091] It should be noted that no matter whether the direction (second direction Y) in which the plug body 14 enters and exits the second channel 120 is a single direction or multiple directions, it is always ensured that the second direction Y intersects with the first direction X, thereby ensuring that after the plug body 14 is in place in the second channel 120, it can play an effective limiting and fixing role between the connector 40 and the implant body 11a.

[0092] In a specific application, the installation sequence of the implant body 11a, the connector 40, and the plug 14 is as follows: first, the implant body 11a is installed in the tooth socket of the oral cavity, and then the connector 40 is inserted into the first channel 110 in the implant body 11a to seat the connector 40. At this time, a second channel 120 is formed between the implant body 11a and the connector 40. Then, the plug 14 is inserted into the second channel 120 to seat the plug 14, thereby achieving a limited fixation between the connector 40 and the implant body 11a. During removal, the plug 14 is first removed to release the limited fixation between the connector 40 and the implant body 11a, and then the connector 40 can be removed from the implant body 11a.

[0093] Optionally, as shown in FIG. 1 and FIG. 4 , the first recess 121 extends from the sidewall surface of the first channel 110 in a direction away from the first channel 110 to form an opening, which is suitable for being at least partially covered by the connector 40 to form the second channel 120 .

[0094] Specifically, the first recessed portion 121 is a groove structure provided on the sidewall of the first channel 110. The first recessed portion 121 extends from the inner wall surface of the first channel 110 in a direction away from the first channel 110 and has an opening facing into the first channel 110. When the connector 40 is in place within the first channel 110, the outer wall of the connector 40 at least partially covers the opening, thereby forming the second channel 120 between the connector 40 and the implant body 11a. This allows the plug body 14 to be positioned to form an undercut fixing structure, thereby securing the connector 40 to the implant body 11a.

[0095] In the embodiment of the present application, a first recessed portion 121 with an opening is provided on the side wall of the first channel 110, so that the first recessed portion 121 is utilized to form a second channel 120 for seating the plug body 14. In this way, the second channel 120 can be formed by cooperating between the connector 40 and the implant body 11a, which not only meets the requirement of forming an inverted concave fixing structure, but also can flexibly set the position of the second channel 120 to meet the needs of different application scenarios.

[0096] In some embodiments, the connector 40 at the position corresponding to the first recessed portion 121 may be a planar structure, a curved structure, or a recessed structure, which is not limited here.

[0097] Optionally, as shown in Figures 1 and 3, when a cross section is made perpendicular to the first direction X, the cross section of the second channel 120 is the first cross section, and the cross section of the first recessed portion 121 is the second cross section; wherein the ratio of the area S1 of the second cross section to the area S2 of the first cross section satisfies: 0<S1 / S2≤1.

[0098] Illustratively, the ratio S1 / S2 of the area S1 of the second cross section to the area S2 of the first cross section can be set to any value such as 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, or a range between any two values.

[0099] In the embodiment of the present application, by setting S1 / S2 to be greater than zero, the plug 14 is ensured to be at least partially embedded in the implant body 11a after it is seated in the second channel 120, thereby forming an undercut fixing structure in the implant body 11a. The structure and size of the first recessed portion 121 forming the second channel 120 can be flexibly adjusted as needed to meet different connection requirements. At the same time, the second channel 120 can be flexibly configured according to the specific matching structure of the connector 40 and the implant body 11a.

[0100] It should be noted that the structures of different portions of the first recessed portion 121 along the extension direction of the second channel 120 can be identical or different. Furthermore, when cross-sections are taken at different locations of the second channel 120 perpendicular to the first direction X, the resulting ratios S1 / S2 can be identical or different, and this is not limited here.

[0101] Optionally, as shown in FIG1 , the sidewall of the first channel 110 includes a curved sidewall 111 and a flat sidewall 112 , the curved sidewall 111 is connected to the flat sidewall 112 , and the flat sidewall 112 is used for guiding.

[0102] In an embodiment of the present application, an arcuate side wall 111 and a plane side wall 112 are provided in the side wall of the first channel 110, so that the plane side wall 112 can be used to guide the connector 40 when the connector 40 enters and exits the first channel 110; at the same time, the portion outside the plane side wall 112 is set as an arcuate side wall 111, which can increase the contact area between the connector 40 and the implant body 11a, disperse the force, and protect the alveolar bone.

[0103] Specifically, the structure of the outer surface of the connector 40 is adapted to the structure of the side wall of the first channel 110 , that is, the outer surface of the connector 40 also includes an arcuate outer wall and a plane outer wall, so that the connector 40 is adapted to the structure of the implant body 11 a .

[0104] 1 , the first recess 121 is formed on the planar sidewall 112. Providing the first recess 121 on the planar sidewall 112 allows the first recess 121 to precisely match the connector 40 to form the second channel 120, facilitating practical structural design and processing.

[0105] It is understood that a second channel 120 is formed between the connector 40 and the implant body 11a, with a portion of the sidewall of the second channel 120 located within the implant body 11a and a portion located within the connector 40. During installation, only when the two portions are precisely aligned can a complete second channel 120 be formed. Therefore, in the present application, the first recessed portion 121 is formed in the planar sidewall 112, so that the implant body 11a and the connector 40 cooperate through a planar guide, thereby improving the alignment accuracy of the different portions of the second channel 120.

[0106] Optionally, as shown in FIG. 1 to FIG. 3 , a threaded hole 130 is further provided on the top of the implant body 11 a , and the threaded hole 130 is used for passing a fastener 51 to connect the connector 40 to the implant body 11 a .

[0107] In an embodiment of the present application, a threaded hole 130 is provided at the top of the implant body 11a so that during the installation process, the fastener 51 can be passed through the connector 40 and threadedly connected to the threaded hole 130 to achieve pre-fixation of the connector 40 and the implant body 11a, thereby facilitating the precise positioning of the bolt body 14 in the second channel 120.

[0108] Specifically, the implant body 11a is used to be installed in the alveolar bone. The top of the implant body 11a refers to one end of the implant body 11a where the entrance of the first channel 110 is provided. The threaded holes 130 can be provided on the end faces of the side walls around the entrance.

[0109] In a specific application, as shown in Figures 1 to 4, the connector 40 is provided with a through hole 41 at a position corresponding to the threaded hole 130. After the connector 40 is installed in the first channel 110, a fastener 51 can be first inserted through the through hole 41 in the connector 40 and threadedly connected to the threaded hole 130 to pre-fix the connector 40 and the implant body 11a, so that the implant body 11a and the connector 40 are precisely aligned to form the second channel 120. Then, the bolt 14 is inserted into the second channel 120 to fully seat the bolt 14. After the connector 40 and the bolt 14 are fully seated, the fastener 51 is removed, completing the installation and fixation of the connector 40 and the implant body 11a.

[0110] The fastener 51 may include a bolt, a screw, or other structural member with an external thread.

[0111] Optionally, as shown in Figures 1 to 5, an embodiment of the present application further discloses a connector 40 for cooperating with the oral implant 11 in the above embodiment, the connector 40 is suitable for being installed in the first channel 110, and the direction in which the connector 40 enters and exits the first channel 110 is the first direction X; wherein, the side wall of the connector 40 is provided with a second recessed portion 122, the second recessed portion 122 is suitable for cooperating with the first recessed portion 121 to form a second channel 120, and the direction in which the plug body 14 enters and exits the second channel 120 is the second direction Y, and the second direction Y intersects with the first direction X.

[0112] In an embodiment of the present application, the connector 40 is installed in the first channel 110 provided in the implant body 11a, and a second recess 122 is provided on the side wall of the connector 40. When the connector 40 is in place in the implant body 11a, the second recess 122 cooperates with the first recess 121 on the implant body 11a to form a second channel 120, so that the plug 14 can be inserted into the second channel 120, and the direction in which the plug 14 enters and exits the second channel 120 intersects with the direction in which the connector 40 enters and exits the first channel 110. In this way, the plug 14 can form an inverted concave fixing structure between the connector 40 and the implant body 11a to limit the connector 40 from falling out of the implant body 11a, thereby achieving the connection and fixation between the connector 40 and the implant body 11a.

[0113] In some embodiments, the first recessed portion 121 and the second recessed portion 122 may be arranged opposite to each other along the radial direction of the second channel 120, so that the first recessed portion 121 and the second recessed portion 122 enclose the second channel 120. In this way, when the plug 14 is in place in the second channel 120, a portion of the plug 14 along the circumferential direction is embedded in the first recessed portion 121, and another portion is embedded in the second recessed portion 122, thereby forming an undercut fixing structure between the connector 40 and the implant body 11a, thereby achieving a connection and fixation between the connector 40 and the implant body 11a.

[0114] In other embodiments, the first recessed portion 121 and the second recessed portion 122 may also be arranged in an axially staggered manner along the second channel 120, with the first recessed portion 121 and the sidewall of the connector 40 enclosing a portion of the second channel 120, and the second recessed portion 122 and the sidewall of the implant body 11a enclosing another portion of the second channel 120. In this way, when the plug 14 is in place within the second channel 120, a portion of the plug 14 along its length is embedded in the first recessed portion 121, and another portion is embedded in the second recessed portion 122, thereby forming an undercut fixing structure between the connector 40 and the implant body 11a, thereby achieving a secure connection between the connector 40 and the implant body 11a.

[0115] In which, when the first recessed portion 121 and the second recessed portion 122 are staggered along the axial direction of the second channel 120, the first recessed portion 121 and the second recessed portion 122 can be completely staggered, that is, the orthographic projection of the first recessed portion 121 along the axial direction perpendicular to the second channel 120 and the orthographic projection of the second recessed portion 122 along the axial direction perpendicular to the second channel 120 do not overlap at all; or, the first recessed portion 121 and the second recessed portion 122 partially overlap, that is, the orthographic projection of the first recessed portion 121 along the axial direction perpendicular to the second channel 120 and the orthographic projection of the second recessed portion 122 along the axial direction perpendicular to the second channel 120 at least partially overlap.

[0116] Optionally, as shown in Figure 1, taking a cross section perpendicular to the first direction X, the cross section of the second channel 120 is the first cross section, and the cross section of the second recessed portion 122 is the third cross section; wherein the ratio of the area S3 of the third cross section to the area S2 of the first cross section satisfies: 0<S3 / S2≤1.

[0117] Illustratively, the ratio S3 / S2 of the area S3 of the third cross section to the area S2 of the first cross section can be set to any value such as 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, or a range between any two values.

[0118] In the embodiment of the present application, by setting S3 / S2 to be greater than zero, it is ensured that after the plug body 14 is in place in the second channel 120, at least a portion of the plug body 14 can be embedded in the connector 40, thereby forming an undercut fixing structure in the connector 40. The structure and size of the second recessed portion 122 forming the second channel 120 can be flexibly adjusted as needed to meet different connection requirements. At the same time, it is convenient to flexibly configure the second channel 120 according to the specific matching structure of the connector 40 and the implant body 11a.

[0119] It should be noted that the structures of different portions of the second recessed portion 122 along the extension direction of the second channel 120 can be identical or different. Furthermore, when cross-sections are taken at different locations of the second channel 120 perpendicular to the first direction X, the resulting ratios S3 / S2 can be identical or different, and this is not limited here.

[0120] Optionally, the present application discloses an oral implant assembly, comprising: a plug body 14, a connector 40 and the oral implant 11 in the above embodiment; wherein, a first channel 110 is provided on the oral implant 11, and the connector 40 is detachably connected to the first channel 110 along a first direction X; a first recess 121 is provided on the side wall of the first channel 110, and a second recess 122 is provided on the side wall of the connector 40, the second recess 122 cooperates with the first recess 121 to form a second channel 120, and the plug body 14 is detachably connected to the second channel 120 along a second direction Y, and the second direction Y intersects with the first direction X.

[0121] In the embodiment of the present application, a first channel 110 is provided in the implant body 11a so that the connector 40 can be installed in the first channel 110, thereby achieving the position of the connector 40 in the implant body 11a. At the same time, a first recessed portion 121 is provided on the side wall of the implant body 11a, and a second recessed portion 122 is provided on the side wall of the connector 40. The first recessed portion 121 and the second recessed portion 122 cooperate to form a second channel 120 between the implant body 11a and the connector 40, and the direction in which the plug 14 enters and exits the second channel 120 intersects with the direction in which the connector 40 enters and exits the first channel 110. Furthermore, when the plug 14 is inserted into the second channel 120, an undercut fixing structure can be formed between the connector 40 and the implant body 11a by the plug 14, thereby preventing the connector 40 from falling out of the implant body 11a, thereby achieving a secure connection between the connector 40 and the implant body 11a.

[0122] With the oral implant assembly of the present application, since the oral implant 11 and the connector 40 are not retained by pressure, the force on the alveolar bone is reduced when the connector 40 is seated in the oral implant 11, reducing alveolar bone absorption. Furthermore, the position and structural design of the second channel 120 are more flexible, facilitating actual installation and removal. Furthermore, the use of an undercut fixing method with the bolt body 14 increases the contact area between the sidewalls of the implant body 11a and the sidewalls of the connector 40, helping to disperse the local force on the oral implant 11, thereby reducing the jaw force per unit area of ​​the alveolar bone and protecting the alveolar bone.

[0123] The specific structures of the oral implant 11 and the connector 40 can be found in the above content, and will not be described in detail in the embodiment of the present application.

[0124] It should be noted that when the first recessed portion 121 and the second recessed portion 122 cooperate to form the second channel 120, the first recessed portion 121 and the second recessed portion 122 can be arranged relative to each other along the radial direction of the second channel 120, or the first recessed portion 121 and the second recessed portion 122 can also be arranged in an axially staggered manner along the second channel 120. It can be flexibly arranged according to actual needs, as long as it is ensured that after the plug body 14 is in place in the second channel 120, it can achieve the limiting and fixing effect on the oral implant 11 and the connector 40. No limitation is made here.

[0125] Optionally, as shown in Figure 6, an embodiment of the present application discloses an oral implant 11, which includes: an implant body 11a, a first channel 110 for accommodating a connector 40 is provided on the implant body 11a, and the direction in which the connector 40 enters and exits the first channel 110 is a first direction X; wherein, a first channel 123 is provided on the side wall of the first channel 110, and the first channel 123 is suitable for communicating with a second channel 124 provided in the connector 40 to form a second channel 120 for accommodating a plug body 14, so as to fix the connector 40 and the implant body 11a through the plug body 14, and the direction in which the plug body 14 enters and exits the second channel 120 is a second direction Y, and the second direction Y intersects with the first direction X.

[0126] In the embodiment of the present application, a first channel 110 is provided in the implant body 11a so that the connector 40 can be installed in the first channel 110, thereby achieving the position of the connector 40 in the implant body 11a. At the same time, a first hole 123 is provided on the side wall of the first channel 110 in the implant body 11a. When the connector 40 is in place in the implant body 11a, the first hole 123 cooperates with the second hole 124 in the connector 40 to form a second channel 120, so that the plug 14 can be inserted into the second channel 120, and the direction in which the plug 14 enters and exits the second channel 120 intersects the direction in which the connector 40 enters and exits the first channel 110. In this way, the plug 14 can form an undercut fixing structure between the connector 40 and the implant body 11a to prevent the connector 40 from falling out of the implant body 11a, thereby achieving a fixed connection between the connector 40 and the implant body 11a.

[0127] With the oral implant 11 structure of the present application, since the oral implant 11 and the connector 40 are not retained by pressure, the force applied to the alveolar bone when the connector 40 is seated in the oral implant 11 is reduced, thus minimizing alveolar bone absorption. Furthermore, the position and structural design of the second channel 120 are more flexible, facilitating actual installation and removal. Furthermore, the undercut fixing method of the bolt body 14 increases the contact area between the sidewalls of the implant body 11a and the sidewalls of the connector 40, helping to disperse the local force applied to the oral implant 11. This, in turn, reduces the jaw force per unit area of ​​the alveolar bone, thereby protecting the alveolar bone.

[0128] Specifically, a first channel 110 is provided in the implant body 11a, and a first hole 123 is provided on the side wall of the first channel 110. Correspondingly, a second channel 124 is provided in the connector 40. When the connector 40 is in place in the first channel 110 of the implant body 11a, the first channel 123 and the second channel 124 correspond to each other and are connected to form a second channel 120. The second channel 120 is for inserting the plug body 14, and the direction in which the plug body 14 enters and exits the second channel 120 is set to intersect with the direction in which the connector 40 enters and exits the first channel 110, thereby forming an inverted concave fixing structure between the implant body 11a and the connector 40, which can realize the limited fixation of the implant body 11a and the connector 40.

[0129] It should be noted that the specific explanations of the first channel 110 , the second channel 120 , the first direction X and the second direction Y in the embodiment of the present application can be performed with reference to the aforementioned embodiment and will not be repeated here.

[0130] Optionally, the first direction X in which the connector 40 enters and exits the first channel 110 includes one or more directions, and the second direction Y intersects any one of the first directions X.

[0131] It is understood that the shape of the first channel 110 can be cylindrical, conical, polyhedral, or other irregular shapes. The connector 40 can include one or more directions of entry and exit of the first channel 110 (i.e., the first direction X). Furthermore, the direction in which the bolt 14 enters and exits the second channel 120 (i.e., the second direction Y) is set to intersect with any one of the first directions X. This avoids the situation where the direction in which the bolt 14 escapes from the second channel 120 is the same as the direction in which the connector 40 escapes from the first channel 110. In this way, no matter which direction the connector 40 escapes from the first channel 110, it will be restricted by the bolt 14, ensuring that the bolt 14 forms a full-range limiting and fixing effect on the connector 40 and the implant body 11a.

[0132] Similarly, regardless of whether the direction (second direction Y) in which the plug body 14 enters and exits the second channel 120 is a single direction or multiple directions, it is always ensured that the second direction Y intersects with the first direction X, thereby ensuring that after the plug body 14 is in place in the second channel 120, it can play an effective role in limiting and fixing the connector 40 and the implant body 11a.

[0133] Optionally, referring to FIG. 1 , the sidewall of the first channel 110 includes a curved sidewall 111 and a flat sidewall 112 , the curved sidewall 111 is connected to the flat sidewall 112 , and the flat sidewall 112 is used for guiding.

[0134] In an embodiment of the present application, an arcuate side wall 111 and a plane side wall 112 are provided in the side wall of the first channel 110, so that the plane side wall 112 can be used to guide the connector 40 when the connector 40 enters and exits the first channel 110; at the same time, the portion outside the plane side wall 112 is set as an arcuate side wall 111, which is convenient for actual processing and can increase the contact area between the connector 40 and the implant body 11a, thereby helping to reduce local stress concentration and thus protecting the alveolar bone.

[0135] Optionally, as shown in FIG. 1 to FIG. 3 , a threaded hole 130 is further provided on the top of the implant body 11 a , and the threaded hole 130 is used for passing a fastener 51 to connect the connector 40 to the implant body 11 a .

[0136] In an embodiment of the present application, a threaded hole 130 is provided at the top of the implant body 11a so that during the installation process, the fastener 51 can be passed through the connector 40 and threadedly connected to the threaded hole 130 to achieve pre-fixation of the connector 40 and the implant body 11a, thereby facilitating the precise positioning of the bolt body 14 in the second channel 120.

[0137] It should be noted that Figure 1 shows the structure of the oral implant 11 in which the first recess 121 and the second recess 122 cooperate to form the second channel 120. The structure of the oral implant 11 at the side wall of the first channel in the embodiment of the present application can refer to the structural setting in Figure 1.

[0138] It is understandable that, except for the structure of the first channel 123 forming the second channel 120 , the structure of the oral implant 11 in the embodiment of the present application can refer to the structure of the oral implant 11 in the above embodiment.

[0139] Optionally, as shown in Figure 6, the present application also provides a connector 40 for cooperating with the oral implant 11 in the above embodiment, the connector 40 is suitable for being installed in the first channel 110, and the direction in which the connector 40 enters and exits the first channel 110 is the first direction X; wherein, a second channel 124 is provided in the connector 40, and the second channel 124 is suitable for being connected with the first channel 123 to form a second channel 120 for accommodating the plug body 14, and the direction in which the plug body 14 enters and exits the second channel 120 is the second direction Y, and the second direction Y intersects with the first direction X.

[0140] In the embodiment of the present application, by providing a second hole 124 in the connector 40, when the connector 40 is installed in the first channel 110 of the oral implant 11, the second hole 124 in the connector 40 communicates with the first hole 123 in the implant body 11a to form the second channel 120, so that the plug 14 can be inserted into the second channel 120, and the direction in which the plug 14 enters and exits the second channel 120 intersects the direction in which the connector 40 enters and exits the first channel 110. In this way, the plug 14 can form an undercut fixing structure between the connector 40 and the implant body 11a, thereby preventing the connector 40 from falling out of the implant body 11a and achieving a secure connection between the connector 40 and the implant body 11a.

[0141] It can be understood that, except for the structure of the second hole 124 forming the second channel 120 , the structure of the connector 40 in the embodiment of the present application can refer to the structural arrangement of the connector 40 in the above embodiment.

[0142] Optionally, as shown in Figure 6, the present application also provides an oral implant component, which includes: a connector 40, a plug body 14 and the oral implant 11 in the above embodiment; wherein, a first channel 110 is provided on the oral implant 11, and the connector 40 is detachably connected to the first channel 110 along a first direction X; a first hole 123 is provided on the side wall of the first channel 110, and the connector 40 is provided with a second hole 124 at a position corresponding to the first hole 123, and the second hole 124 is connected to the first hole 123 to form a second channel 120, and the plug body 14 is detachably connected to the second channel 120 along a second direction Y, and the second direction Y intersects with the first direction X.

[0143] In an embodiment of the present application, a first channel 110 is provided in the implant body 11a so that the connector 40 can be installed in the first channel 110, thereby realizing the positioning of the connector 40 in the implant body 11a. At the same time, a first channel 123 is provided on the side wall of the first channel 110 in the implant body 11a, and a second channel 124 is provided on the side wall of the connector 40. When the connector 40 is fully in place in the implant body 11a, the first channel 123 is connected to the second channel 124 to form a second channel 120, so that the plug 14 can be inserted into the second channel 120, and the direction in which the plug 14 enters and exits the second channel 120 intersects with the direction in which the connector 40 enters and exits the first channel 110. In this way, after the plug body 14 is in place in the second channel 120, it can form an undercut fixing structure in the implant body 11a and the connector 40 respectively to limit the connector 40 from falling out of the implant body 11a, thereby achieving the connection and fixation between the connector 40 and the implant body 11a.

[0144] It should be noted that the oral implant component of the embodiment of the present application can be regarded as a case where S1 / S2=1 and S3 / S2=1 as mentioned above, in order to enable the plug body 14 to be embedded in the implant body 11a and the plug body 14 to be embedded in the connector 40, so as to achieve the fixing effect on the connector 40 and the implant body 11a, and then a channel structure is respectively set in the implant body 11a and the connector 40 to form a second channel 120.

[0145] Alternatively, as shown in Figures 1, 5, and 6, a portion of the plug body 14 is embedded in the oral implant 11, and another portion of the plug body 14 is embedded in the connector 40. In this way, the plug body 14 and the second channel 120 cooperate to form an undercut fixing structure in both the implant body 11a and the connector 40, thereby achieving a connection and fixation between the connector 40 and the oral implant 11.

[0146] In some embodiments, the bolt body 14 is slidably connected to the second channel 120. By making the bolt body 14 slidably connected to the second channel 120, installation and removal of the bolt body 14 are facilitated.

[0147] In some embodiments, the bolt body 14 is threadedly connected to the second channel 120 .

[0148] Specifically, an internal thread can be set on the inner wall of the second channel 120, and an external thread can be set on the outer wall of the bolt body 14. The bolt body 14 is threadedly connected to the internal thread of the second channel 120 through the external thread to achieve the installation and fixation of the bolt body 14 in the second channel 120, which can increase the connection firmness between the bolt body 14 and the side wall of the second channel 120.

[0149] Optionally, as shown in Figures 1 to 3, the oral implant component also includes a fastener 51; wherein, a threaded hole 130 is also provided at the top of the implant body 11a; the connector 40 is provided with a through hole 41 at a position corresponding to the threaded hole 130, and the fastener 51 is passed through the through hole 41 and connected to the threaded hole 130 to connect the connector 40 to the implant body 11a.

[0150] In an embodiment of the present application, a threaded hole 130 is provided at the top of the implant body 11a, and during the installation process of the connector 40 and the implant body 11a, the fastener 51 can be passed through the through hole 41 of the connector 40 and threadedly connected to the threaded hole 130 to achieve pre-fixation of the connector 40 and the implant body 11a, thereby facilitating the precise positioning of the bolt body 14 in the second channel 120.

[0151] In a specific application, after the connector 40 is installed in the first channel 110, the fastener 51 can be inserted through the through hole 41 in the connector 40 and threadedly connected to the threaded hole 130 to pre-fix the connector 40 and the implant body 11a. Then, the plug 14 is inserted into the second channel 120 and fully seated. After both the connector 40 and the plug 14 are fully seated, the fastener 51 is removed, completing the installation and fixation of the connector 40 and the implant body 11a.

[0152] Optionally, as shown in FIG. 3 and FIG. 5 , the oral implant assembly further includes: an elastic material layer 32 , and the elastic material layer 32 is disposed between the implant body 11 a and the connector 40 .

Furthermore, the elastic material layer 32 also acts as a buffer between the connector 40 and the implant body 11a, thereby better mimicking the connection between a natural tooth and alveolar bone and being more consistent with biological characteristics. Of course, the elastic material layer 32 can also serve other purposes, such as serving as a carrier for sustained-release drugs, which are not limited in this application.

[0154] In some embodiments, as shown in FIG. 3 and FIG. 5 , an elastic material layer 32 may also be filled between the plug body 14 and the inner wall of the second channel 120 to perform sealing, buffering, and other functions between the plug body 14 and the inner wall of the second channel 120 .

[0155] In other embodiments, as shown in Figures 2 and 3, the first channel 110 has a bottom wall arranged opposite to the opening. When the connector 40 is set as a transfer base or a healing base, a second additional screw channel 23 may also be provided in the bottom wall. Accordingly, a threaded connection portion may be provided at the end of the connector 40. When the connector 40 is installed in the first channel 110, the threaded connection portion can be threadedly connected to the second additional screw channel 23.

[0156] Optionally, as shown in FIG. 5 and FIG. 6 , the oral implant assembly further includes a cap 52 . When the plug body 14 is fully seated in the second channel 120 , the cap 52 is at least partially embedded in the entrance of the second channel 120 .

[0157] In an embodiment of the present application, by providing a cap 52, after the plug body 14 is installed in the second channel 120, the cap 52 is used to block the entrance of the second channel 120 to prevent impurities from entering the second channel 120, and at the same time, it can also limit and fix the plug body 14 in the second channel 120.
