Description

Technical Field

[0001] The invention relates to the technical field of oral implantation, and in particular to a healing base assembly. Background Art

[0002] The healing abutment is a temporary device installed to promote the healing of gingival tissue after the implant is placed in the alveolar bone. Its main function is to guide and shape the gingival tissue, ensure that the gums form a suitable cuff structure around the implant, and create an ideal soft tissue environment for the subsequent installation of the permanent abutment and restoration.

[0003] As for the preparation of the crown in the later stage, the healing abutment must be removed first, and then the scanning rod is installed on the implant to scan the patient's mouth. The removal process of the healing abutment is time-consuming, which increases the workload of medical staff. Summary of the invention

[0004] The present invention provides a healing abutment assembly and a healing abutment, and the technical problem to be solved is: how to reduce the work intensity of medical staff during the preparation of the dental crown.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0011] Furthermore, the bolt hole and the mounting hole directly form a step surface. When the bolt is inserted into the bolt hole and fixed to the implant, the head of the bolt presses the step surface, thereby enabling the healing base to be fixedly connected to the implant.

[0012] Furthermore, the plug-in portion includes a limit base, an opening piece, and a positioning protrusion; wherein the limit base is fixed to the lower part of the scanning rod base, and a plurality of opening pieces are fixed to the lower end of the limit base; the plurality of opening pieces are surrounded by an insertion hole in the middle, the insertion hole is in a truncated cone shape, and the lower end of the insertion hole is smaller than the diameter of the upper end; and the scanning rod base is provided with a through hole, and the lower end of the through hole is connected to the upper end of the insertion hole;

[0013] A positioning protrusion is fixedly provided on the outside of at least one of the opening members; a positioning groove is provided in the mounting hole;

[0014] When the plug-in part is inserted into the mounting hole, the positioning protrusion corresponds to the positioning groove; it also includes a locking piece, which can extend into the through hole and the insertion hole, and a conical locking part is provided at the lower end of the locking piece; when the conical locking part is inserted into the insertion hole, a plurality of expanding parts are pushed outward by the conical locking part, so that the positioning protrusion is squeezed into the positioning groove.

[0015] Furthermore, in the installation state of the healing base and the scanning rod, the limiting base and the limiting hole cooperate with each other; the cross-sections of the limiting base and the limiting hole are the same, and the cross-section is non-circular.

[0016] Furthermore, the limiting hole presents a gradually expanding shape from bottom to top, and the gradually expanding shape from bottom to top facilitates the insertion of the plug-in part.

[0017] Furthermore, a smooth columnar body with a height of 2-4 mm was built above the gingival part, and a hexagonal retention design with a width and thickness of 1 mm was cut on the top;

[0018] After the free gingival grafting operation is completed, silicone rubber is coated on the model to cover the abutment and the edge of the surgical area and extend 2mm; the customized abutment and silicone rubber together form a stent device to assist in the postoperative stability of the free gingival grafting, increase the area of ​​keratinized tissue, and increase the depth of the vestibule groove.

[0019] The beneficial effects of the present invention are:

[0020] (1) Stability

[0021] Stable connection ensures the stability of the abutment: The connection portion 11 of the healing abutment 10 plays a key role and can be firmly connected to the implant implanted in the gums, ensuring the stability of the abutment body in the oral environment and laying a solid foundation for subsequent operations.

[0022] The gingival penetration part helps long-term stability: The special structure of the gingival penetration part 12 can smoothly pass through the gingival tissue and build a gingival cuff, which is of great significance to the long-term stability of the implant and oral health.

[0023] (2) Operational convenience

[0024] Flexible disassembly simplifies the process: The scanning rod 20 and the healing base 10 are detachably connected. When shaping the gums, you only need to install the healing base 10 on the implant, and the scanning rod 20 can be temporarily disassembled to avoid interfering with the shaping process. When entering the stage of acquiring oral image information, the scanning rod 20 can be conveniently installed on the healing base 10 to carry out scanning work. There is no need to remove the healing base 10 and then install the scanning rod 20 as in the traditional way, which greatly simplifies the operation process.

[0025] (3) Medical care and surgical quality

[0026] Reduce work intensity: The innovative design eliminates the cumbersome and complicated steps in traditional operations, significantly reducing the workload of medical staff.

[0027] Improve surgical efficiency and quality: It improves the efficiency and quality of oral implant surgery as a whole, allowing medical staff to complete each stage of work more efficiently. It also helps to ultimately form a gingival cuff that meets oral health and implant needs, thereby ensuring the effectiveness of the surgery.

[0028] Anti-rotation structure and connection rationality

[0029] (4) Effective anti-rotation to ensure precision: A limiting surface 111 (such as a regular hexagon or other non-circular cross-section) is set on the periphery of the connecting part 11 to cooperate with the corresponding part of the implant, or other anti-rotation structures such as limiting blocks and limiting grooves are used to prevent the healing base 10 and the implant from rotating relative to each other, thereby ensuring the precision of the connection and use of each component.

[0030] Reasonable connection facilitates operation: The healing base 10 and the scanning rod 20 are reasonably and firmly connected through structures such as the plug-in part 21, such as the use of the opening piece 212, the positioning protrusion 213, the positioning groove 151 and the locking piece. At the same time, the limiting base 211 and the limiting hole 16 cooperate with each other, and the shape of the limiting hole 16 is convenient for the insertion of the plug-in part 21, so that the connection operation between the two is convenient and reliable.

[0031] In the technical solution of the present invention, the healing base 10 is connected to the implant through the connecting part 11, so that after the implant is implanted in the patient's mouth, the gums can be shaped with the help of the healing base 10 to form a gum cuff. In addition, the present solution includes a detachable scanning rod 20, which can be connected to the healing base 10. During the gum shaping process, the scanning rod 20 can be removed from the healing base 10, and only the healing base 10 needs to be installed. When preparing the crown at a later stage, if it is necessary to perform an image scan of the oral cavity through the scanning rod 20, the scanning rod 20 can be directly installed on the healing base 10. This design eliminates the tedious steps of disassembling the healing base 10 before installing the scanning rod 20, effectively reducing the workload of medical staff.

[0038] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0039] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0040] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0041] Embodiment 1

[0042] Referring to the accompanying drawings, a healing base assembly includes a healing base 10 and a scanning rod 20;

[0043] The healing base 10 includes a connecting portion 11, a gingival portion 12, and a healing cap 13; the connecting portion 11 is fixedly connected to the first end of the gingival portion 12, and the connecting portion 11 is used to connect to an implant, and the implant is implanted in the alveolar bone of the edentulous area; the healing cap 13 is fixed to the second end of the gingival portion 12; the connecting portion 11, the gingival portion 12, and the healing cap 13 are integrally formed.

[0044] The scanning rod 20 includes an inserting portion 21 , a marking surface 22 , and a scanning rod base 23 ; the inserting portion 21 is fixedly provided at the lower end of the scanning rod base 23 , and the inserting portion 21 is used for detachably connecting with an end of the healing base 10 away from the connecting portion 11 .

[0045] In the present invention, the connection portion 13 of the healing abutment 10 plays a key role, and its main purpose is to firmly connect with the implant, and the implant is located in the gums, so as to ensure the stability of the abutment body in the oral environment and provide a solid foundation for a series of subsequent operations. The gingival portion 12 has a special structure, which enables it to smoothly pass through the gingival tissue, thereby successfully building a gingival cuff above the implant, which is of great significance to the long-term stability of the implant and oral health.

[0046] The scanning rod 20 has a unique design concept. It is mainly used in oral scanners for scanning. Its identification surface 22 is used to display clear and accurate positioning identification, thereby providing an accurate reference for oral scanning. The connection between the scanning rod 20 and the healing base 10 is detachable, and it is connected to the end of the healing base 10 away from the connecting part 11. This connection method brings great convenience. When performing the key step of gingival plasticity, it is only necessary to install the healing base 10 on the implant, and the scanning rod 20 can be temporarily removed to avoid interference with the gingival plasticity process. When entering the stage of obtaining oral image information, in order to cooperate with the work of the oral scanner, the scanning rod 20 can be conveniently installed directly on the healing base 10. There is no need to remove the healing base 10 and then install the scanning rod 20 as in the traditional way, which greatly simplifies the operation process.

[0047] From the perspective of the overall technical solution, the healing base 10 is closely connected to the implant through the connecting part 11. This connection enables the healing base 10 to accurately shape the gums after the implant is implanted in the patient's mouth, and finally forms a gum cuff that meets the oral health and implant requirements. At the same time, the detachable scanning rod 20 designed by the present invention can be flexibly connected and disassembled with the healing base 10. During the critical period of gum shaping, the scanning rod 20 can be removed from the healing base 10, leaving only the healing base 10 for work; and in the subsequent stage of preparing the crown, if the scanning rod 20 is needed to scan the oral cavity to obtain accurate data, the scanning rod 20 can be directly installed on the healing base 10 to quickly carry out the scanning work. This innovative design cleverly eliminates the cumbersome and complicated steps of disassembling the healing base 10 before installing the scanning rod 20 in the traditional operation, significantly reduces the workload of medical staff, improves the overall efficiency and quality of oral implant surgery, and brings a more efficient and high-quality experience to patients' oral restoration.

[0048] Furthermore, a limiting surface 111 is provided on the outer periphery of the connection portion 11 of the healing abutment 10, and the cross-sectional shape of the limiting surface 111 is non-circular; the cross-sectional shape of the limiting surface 111 is the same as the cross-sectional shape of the corresponding implant; thus, when the limiting surface 111 of the connection portion 11 is placed in the corresponding installation position of the implant, the relative rotation between the healing abutment 10 and the implant can be prevented. The cross-sectional shape of the limiting surface 111 is preferably a regular hexagon.

[0049] In addition, the present application is not limited thereto, and in other embodiments, the outer circumferential surface of the connection portion 11 of the healing abutment 10 may form a limiting block, and the inner circumferential surface of the implant may form a limiting groove correspondingly, and the limiting block abuts against the limiting groove to cooperate to form an anti-rotation structure. Alternatively, the connection portion 11 of the healing abutment 10 and the inner circumferential surface of the scanning rod 20 both form limiting grooves, and a limiting block is inserted, with part of the limiting block located in the limiting groove of the connection portion 11 of the healing abutment 10 and part of the limiting block located in the upper limiting groove of the scanning rod 20.

[0050] Furthermore, the healing base 10 is provided with a bolt hole 14, a mounting hole 15, and a limiting hole 16 from bottom to top; and the bolt hole 14, the mounting hole 15, and the limiting hole 16 are connected in sequence; the bolt hole 14 and the limiting hole 16 are exposed on both upper and lower end surfaces of the healing base 10;

[0051] Furthermore, the bolt hole 14 and the mounting hole 15 directly form a step surface 145. When the bolt is inserted into the bolt hole 14 and fixed to the implant, the head of the bolt presses the step surface 145, so that the healing base 10 can be fixedly connected to the implant.

[0052] In addition, when the healing abutment 10 is installed on the implant, the connecting portion 11 of the healing abutment 10 is inserted into the mounting hole of the implant, and the limiting surface 111 of the connecting portion 11 of the healing abutment 10 cooperates with the corresponding portion of the mounting hole of the implant, thereby preventing the healing abutment 10 from rotating relative to the implant.

[0053] Furthermore, the plug-in portion 21 includes a limit base 211, an opening piece 212, and a positioning protrusion 213; wherein the limit base 211 is fixed to the lower part of the scanning rod base 23, and multiple opening pieces 212 are fixed to the lower end of the limit base 211; the multiple opening pieces 212 form an insertion hole in the middle, and the insertion hole is truncated cone-shaped, and the lower end of the insertion hole is smaller in diameter than the upper end; and the scanning rod base 23 is provided with a through hole, and the lower end of the through hole is connected to the upper end of the insertion hole.

[0054] A positioning protrusion 213 is fixedly disposed on the outside of at least one of the unfolding members 212 ; a positioning groove 151 is formed in the mounting hole 15 .

[0055] When the plug-in part 21 is inserted into the mounting hole 15, the positioning protrusion 213 corresponds to the positioning groove 151; it also includes a locking piece, which can extend into the through hole and the insertion hole, and a truncated cone locking part is provided at the lower end of the locking piece; when the truncated cone locking part is inserted into the insertion hole, the multiple opening pieces 212 are stretched outward by the truncated cone locking part, so that the positioning protrusion 213 is squeezed into the positioning groove 151; the installation operation of the healing base 10 and the scanning rod 20 is completed.

[0056] Furthermore, in the installation state of the healing base 10 and the scanning rod 20, the limiting base 211 and the limiting hole 16 cooperate with each other; the cross-section of the limiting base 211 and the limiting hole 16 is the same, and the cross-section is non-circular.

[0057] Furthermore, the limiting hole 16 presents a gradually expanding shape from bottom to top, and the gradually expanding shape from bottom to top facilitates the insertion of the plug-in portion 21 .

[0058] In addition, the healing abutment component has the following advantages and effects:

[0059] (1) Stability

[0060] Stable connection ensures the stability of the abutment: The connection portion 11 of the healing abutment 10 plays a key role and can be firmly connected to the implant implanted in the gums, ensuring the stability of the abutment body in the oral environment and laying a solid foundation for subsequent operations.

[0061] The gingival penetration part helps long-term stability: The special structure of the gingival penetration part 12 can smoothly pass through the gingival tissue and build a gingival cuff, which is of great significance to the long-term stability of the implant and oral health.

[0062] (2) Operational convenience

[0063] Flexible disassembly simplifies the process: The scanning rod 20 and the healing base 10 are detachably connected. When shaping the gums, you only need to install the healing base 10 on the implant, and the scanning rod 20 can be temporarily disassembled to avoid interfering with the shaping process. When entering the stage of acquiring oral image information, the scanning rod 20 can be conveniently installed on the healing base 10 to carry out scanning work. There is no need to remove the healing base 10 and then install the scanning rod 20 as in the traditional way, which greatly simplifies the operation process.

[0064] (3) Medical care and surgical quality

[0066] Improve surgical efficiency and quality: It improves the efficiency and quality of oral implant surgery as a whole, allowing medical staff to complete each stage of work more efficiently. It also helps to ultimately form a gingival cuff that meets oral health and implant needs, thereby ensuring the effectiveness of the surgery.

[0067] Anti-rotation structure and connection rationality

[0068] (4) Effective anti-rotation to ensure precision: A limiting surface 111 (such as a regular hexagon or other non-circular cross-section) is set on the periphery of the connecting part 11 to cooperate with the corresponding part of the implant, or other anti-rotation structures such as limiting blocks and limiting grooves are used to prevent the healing base 10 and the implant from rotating relative to each other, thereby ensuring the precision of the connection and use of each component.

[0069] Reasonable connection facilitates operation: The healing base 10 and the scanning rod 20 are reasonably and firmly connected through structures such as the plug-in part 21, such as the use of the opening piece 212, the positioning protrusion 213, the positioning groove 151 and the locking piece. At the same time, the limiting base 211 and the limiting hole 16 cooperate with each other, and the shape of the limiting hole 16 is convenient for the insertion of the plug-in part 21, so that the connection operation between the two is convenient and reliable.

[0070] In short, the healing abutment component optimizes oral implant-related operations in many aspects, and plays a positive and important role in ensuring the quality of the surgery itself, improving the work of medical staff and patients' oral restoration experience.

[0071] Embodiment 2

[0072] Referring to the drawings of the second embodiment, compared with the first embodiment, the external shape of the second embodiment is changed;

[0073] A smooth column with a height of 2-4 mm is built above the gingival part 12, and a hexagonal retention design with a width and thickness of 1 mm is cut on the top.
