Description

Technical Field

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

[0002] Implant dentures are widely used in the field of oral dentistry due to their reliability and aesthetics. In related technologies, after the implant is implanted, the gums are generally shaped and a gingival cuff is formed through a healing base. However, it takes a period of time to recover from the completion of the healing base in the patient's mouth to the formation of a better gingival cuff. During this recovery period, the exposed healing base may cause the gums in this area to contact foreign objects and cause oral infection, affecting the shaping effect of the gums. Summary of the invention

[0003] The main purpose of the present invention is to provide a healing base, aiming to avoid the healing base being exposed in the oral cavity, reduce the possibility of causing oral infection, and ensure the shaping effect on the gums.

[0004] To achieve the above-mentioned purpose, the healing abutment proposed by the present invention comprises:

[0005] an abutment body, the abutment body comprising a main body section, a gum matching section and a connecting section, one end of the gum matching section is connected to one end of the main body section, one end of the connecting section is connected to one end of the gum matching section away from the main body section, the other end of the connecting section is used to connect to an implant, and in the direction from the main body section to the connecting section, the cross-sectional area of ​​the gum matching section is gradually reduced; and

[0006] A protective sleeve is sleeved on the main body section.

[0007] In one embodiment of the present invention, the main body section includes:

[0008] a base connected to an end of the gingival engagement section away from the connection section; and

[0009] A convex column connected to a surface of the base facing away from the gum matching section, wherein the cross-sectional area of ​​the convex column is smaller than the cross-sectional area of ​​the base;

[0010] The protective sleeve is sleeved on the convex column and abuts against the base.

[0011] In one embodiment of the present invention, the protective sleeve is a cylindrical structure, and is formed with openings at one end facing the base and at one end away from the base.

[0012] In one embodiment of the present invention, a distance between an opening of one end of the protective cover away from the base and the base is greater than a distance between an end surface of one end of the protrusion away from the base and the base.

[0013] In one embodiment of the present invention, an inner wall of the protective cover is provided with abutment ribs, the abutment ribs are arranged around the circumference of the protective cover, and the abutment ribs abut against a surface of the protruding column away from the base.

[0014] In one embodiment of the present invention, the abutment rib divides the inner space of the protective cover into a first hole segment and a second hole segment that are connected, the first hole segment passes through the end surface of the protective cover facing away from the base, the second hole segment passes through the end surface of the protective cover facing the base, and the cross-sectional area of ​​the second hole segment is greater than the cross-sectional area of ​​the first hole segment.

[0015] In one embodiment of the present invention, a first inclined surface is formed at the connection between the surface of the boss facing away from the base and the side circumferential surface of the boss, and a second inclined surface is formed at the connection between the surface of the abutment rib facing the second hole segment and the hole wall of the second hole segment, and the second inclined surface abuts against the first inclined surface.

[0016] In one embodiment of the present invention, the outer peripheral surface of the protective cover and the surface of the protective cover facing away from the base are arranged in a smooth transition.

[0017] In one embodiment of the present invention, the outer peripheral surface of the protective cover and the side peripheral surface of the base are arranged in the same plane.

[0018] In one embodiment of the present invention, the projections of the protective sleeve, the main body section, the gum matching section and the connecting section on the horizontal plane are all circular;

[0019] And / or, the main body section, the gingival fitting section and the connecting section are an integral structure.

[0020] The healing abutment of the technical solution of the present invention is connected to the implant through a connecting section, so that after the implant is implanted in the patient's mouth, the healing abutment can be used to shape the gums, thereby forming a gum cuff. In addition, since the cross-sectional area of ​​the gum matching section of the healing abutment in this solution is gradually reduced in the direction of the main section facing the connecting section, the contact area between the healing abutment and the gums can be increased, and the healing abutment and the gums can be more closely fitted, thereby improving the stability of the fixation of the healing abutment to ensure the shaping effect on the gums. Furthermore, the healing abutment in this solution also includes a protective cover, which can be sleeved on the main section of the healing abutment to isolate foreign objects from the gums at the lower end of the healing abutment, making it difficult for foreign objects to contact the gums at the lower end of the healing abutment, thereby reducing the possibility of causing oral infection and further ensuring the shaping effect on the gums.

[0033] Please refer to Figure 1 , Figure 2 as well as Figure 3 , the present invention proposes a healing base 100 .

[0034] In one embodiment of the present invention, the healing abutment 100 includes an abutment body 10 and a protective cover 30; wherein, the abutment body 10 includes a main body section 11, a gingival matching section 13 and a connecting section 15, one end of the gingival matching section 13 is connected to one end of the main body section 11, one end of the connecting section 15 is connected to the end of the gingival matching section 13 away from the main body section 11, and the other end of the connecting section 15 is used to connect to the implant 300, and in the direction from the main body section 11 to the connecting section 15, the cross-sectional area of ​​the gingival matching section 13 is gradually reduced; the protective cover 30 is sleeved on the main body section 11.

[0035] In one embodiment of the present invention, the upper end of the main section 11 of the abutment body 10 is exposed to the outside world, and can be mainly used to install the protective cover 30. The gingival matching section 13 can be mainly used to increase the abutment area of ​​the gums, thereby improving the stability of the installation of the abutment body. Among them, the cross-sectional area of ​​the gingival matching section 13 is set to be gradually reduced, and the side surface of the gingival matching section 13 can be set as an inclined plane, or the side surface of the gingival matching section 13 can be set as an arc surface. The connecting section 15 can be mainly used to connect with the implant 300 located in the gums, so as to fix the abutment body 10 in the oral cavity. The protective cover 30 can be mainly used to be set on the outside of the main section 11, and play a role in isolating foreign objects from the gums at the lower end of the healing abutment 100.

[0036] The healing abutment 100 of the technical solution of the present invention is connected to the implant 300 through the connecting section 15, so that after the implant 300 is implanted in the patient's mouth, the healing abutment 100 can be used to shape the gums, thereby forming a gum cuff. In addition, since the cross-sectional area of ​​the gum matching section 13 of the healing abutment 100 in this solution is gradually reduced in the direction of the main section 11 facing the connecting section 15, the contact area between the healing abutment 100 and the gums can be increased, and the healing abutment 100 and the gums can be more closely attached, thereby improving the stability of the fixation of the healing abutment 100 to ensure the shaping effect on the gums. Furthermore, the healing base 100 in the present embodiment also includes a protective cover 30, which can be mounted on the main body section 11 of the healing base 100 to isolate foreign objects from the gums at the lower end of the healing base 100, making it difficult for foreign objects to come into contact with the gums at the lower end of the healing base 100, thereby reducing the possibility of causing oral infection and further ensuring the shaping effect of the gums.

[0037] Please refer to Figure 2 and Figure 4In one embodiment of the present invention, the main body section 11 includes a base 111 and a boss 113, the base 111 is connected to one end of the gum matching section 13 away from the connecting section 15; the boss 113 is connected to the surface of the base 111 away from the gum matching section 13, and the cross-sectional area of ​​the boss 113 is smaller than the cross-sectional area of ​​the base 111; the protective cover 30 is sleeved on the boss 113 and abuts against the base 111.

[0038] It can be understood that the base 111 can play a role in abutting and limiting the protective sleeve 30, ensuring that the protective sleeve 30 is accurately mounted on the preset installation position to play a better isolation and protection role. And mounting the protective sleeve 30 on the boss 113 with a relatively small cross-sectional area can make the connection between the protective sleeve 30 and the base body more compact, reducing the space occupied in the oral cavity. Of course, the present application is not limited to this. In other embodiments, the cross-sectional area of ​​the base 111 and the cross-sectional area of ​​the boss 113 can also be the same, and both can be set relatively small to avoid occupying too much space in the oral cavity.

[0039] In one embodiment of the present invention, the protective cover 30 is a cylindrical structure, and has openings formed at one end facing the base 111 and at one end away from the base 111 .

[0040] It can be understood that the protective sleeve 30 is a cylindrical structure with two ends open, so that the shape and structure of the protective sleeve 30 are relatively simple, thereby improving the convenience of manufacturing the protective sleeve 30. At the same time, the protective sleeve 30 also has a side wall, so that the raw materials required for manufacturing are relatively small, which is conducive to reducing the manufacturing cost of the protective sleeve 30. Of course, the present application is not limited to this. In other embodiments, the protective sleeve 30 may also include a sleeve top wall and a sleeve side wall, and the sleeve side wall is connected to the sleeve top wall and is arranged around the periphery of the sleeve top wall to play a better isolation and protection role.

[0041] In one embodiment of the present invention, the distance between the opening of the protective cover 30 away from the base 111 and the base 111 is greater than the distance between the end surface of the protrusion 113 away from the base 111 and the base 111 .

[0042] It can be understood that the height of the protective sleeve 30 is higher than the height of the convex column 113, which can reduce the possibility of foreign objects entering the protective sleeve 30 and further entering between the protective sleeve 30 and the convex column 113, thereby being more conducive to ensuring the cleanliness of the area and providing better protection for the oral cavity. Of course, the present application is not limited to this, and in other embodiments, the height of the protective sleeve 30 and the height of the convex column 113 may also be the same.

[0043] Please refer to Figure 2 , Figure 3 as well as Figure 4In one embodiment of the present invention, an inner wall of the protective cover 30 is provided with abutment ribs 31 , which are arranged around the circumference of the protective cover 30 , and abutment ribs 31 abut against the surface of the protrusion 113 away from the base 111 .

[0044] It can be understood that by abutting the abutting rib 31 against the boss 113, the protective cover 30 can be further limited during the sleeve installation process to further ensure that the protective cover 30 is accurately sleeved at the preset installation position. At the same time, through the setting of the abutting rib 31, the protective cover 30 can also be fixed by inserting a locking member 500, so that there is no need to set a connecting structure in the protective cover 30 and simplify the structure of the protective cover 30. Specifically, the locking member 500 passes through the protective cover 30 and is inserted into the boss 113, and the locking member 500 and the boss 113 cooperate to clamp and fix the protective cover 30. At this time, the locking member 500 can be a screw, and a threaded hole that cooperates with it can be provided in the main section 11. Of course, the locking member 500 and the boss 113 of the main section 11 can also be through magnetic attraction, that is, each is embedded with a magnetic block that attracts each other. Alternatively, the protective cover 30 can be directly bonded to the boss 113 of the main section 11 by glue.

[0045] Please refer to Figure 4 In one embodiment of the present invention, the abutment rib 31 separates the inner space of the protective cover 30 into a first hole segment 33 and a second hole segment 35 which are connected to each other. The first hole segment 33 penetrates the end surface of the protective cover 30 which faces away from the base 111, and the second hole segment 35 penetrates the end surface of the protective cover 30 which faces the base 111. The cross-sectional area of ​​the second hole segment 35 is greater than the cross-sectional area of ​​the first hole segment 33.

[0046] It can be understood that the second hole section 35 is larger than the first hole section 33, so that the second hole section 35 has a larger cross section. At this time, the possibility of contact with the side of the boss 113 and friction can be reduced (that is, there is a certain gap between the hole wall of the second hole section 35 and the boss 113), so that it is easy to put the protective cover 30 on the boss 113. At the same time, because the second hole section 35 is larger than the first hole section 33, the two ends of the protective cover 30 are different, so that when the protective cover 30 is put on the boss 113, it has an installation prompt function, so that the installer can put the end of the protective cover 30 with the second hole section 35 on the boss 113 and install the protective cover 30 in place at one time.

[0047] In one embodiment of the present invention, a first inclined surface 1131 is formed at the connection between the surface of the boss 113 facing away from the base 111 and the side circumferential surface of the boss 113, and a second inclined surface 37 is formed at the connection between the surface of the abutment rib 31 facing the second hole segment 35 and the hole wall of the second hole segment 35, and the second inclined surface 37 abuts against the first inclined surface 1131.

[0048] It can be understood that when the protective cover 30 is sleeved on the boss 113, the first inclined surface 1131 can guide the protective cover 30 to be accurately inserted, thereby reducing the requirements for the alignment accuracy of the protective cover 30 and the boss 113 during installation. When the protective cover 30 is inserted into the boss 113, the first inclined surface 1131 and the second inclined surface can abut against each other, and the position of the protective cover 30 can be adjusted in the horizontal direction through the cooperation of the two, reducing the possibility of the protective cover 30 being offset in the horizontal direction, which may affect the subsequent installation and insertion of the fastener 700. At the same time, the contact area between the protective cover 30 and the boss 113 is also increased through the abutment between the first inclined surface 1131 and the second inclined surface, thereby improving the stability of the installation of the protective cover 30.

[0049] In one embodiment of the present invention, the outer peripheral surface of the protective cover 30 and the surface of the protective cover 30 facing away from the base 111 are arranged in a smooth transition.

[0050] It can be understood that the outer circumferential surface of the protective cover 30 and the surface of the protective cover 30 facing away from the base 111 are smoothly transitioned, so that no edges are formed there. At this time, the possibility of the protective cover 30 scratching the oral wall can be reduced, thereby improving the safety of the healing base 100 during use.

[0051] In one embodiment of the present invention, the outer circumference of the protective cover 30 and the circumference of the base 111 are coplanar.

[0052] It can be understood that the outer peripheral surface of the protective cover 30 and the side peripheral surface of the base 111 are located in the same plane, which can better isolate the gums at the lower end of the healing base 100 from foreign objects, and also reduce the possibility of the protective cover 30 causing compression damage to the gums around the base body 10. Of course, the present application is not limited to this, and in other embodiments, the outer peripheral surface of the protective cover 30 can also be slightly larger than the side peripheral surface of the base 111.

[0053] Please refer to Figure 2 In one embodiment of the present invention, the projections of the protective sleeve 30, the main body section 11, the gum matching section 13 and the connecting section 15 on the horizontal plane are all circular.

[0054] It can be understood that the protective cover 30, the main body section 11, the gum matching section 13 and the connecting section 15 are all circular in shape, which makes the healing base 100 relatively small in size and reduces the space occupied in the gums. At this time, the peripheral side of the base body 10 also has good consistency, which is convenient for the peripheral side of the base body 10 and the gums to fit evenly and tightly, thereby ensuring the stability of the fixation of the base body 10. At the same time, such a setting can also make the shapes of the base body 10 and the protective cover 30 more regular and convenient for molding and manufacturing, and there is no need to consider the directionality when fixing, which is conducive to improving the convenience of installation of the base body 10 and the protective cover 30. Of course, the present application is not limited to this. In other embodiments, the projections of the protective cover 30, the main body section 11, the gum matching section 13 and the connecting section 15 on the horizontal plane are all circular in shape, and the projections on the horizontal plane are all square or other shapes. The connecting section 15 and the implant 300 can be locked and fixed by a fastener 700, which passes through the connecting section 15 and is inserted into the implant 300. In this case, the fastener 700 can be a screw, and in order to facilitate the installation and replacement of the fastener 700, the base body can be formed with a through hole that runs through the main section 11, the gum matching section 13 and the connecting section 15, the upper section of the through hole forms an internal thread connected to the locking member 500, and the lower section accommodates the fastener 700.

[0055] In one embodiment of the present invention, the main body section 11, the gingival matching section 13 and the connecting section 15 are an integral structure.

[0056] It can be understood that the main body section 11, the gum matching section 13 and the connecting section 15 are integrated, so that the strength of the connecting parts can be enhanced, thereby improving the overall strength of the abutment body 10. At the same time, such a configuration also allows the abutment body 10 to be manufactured by integral molding, thereby facilitating the improvement of the production efficiency of the abutment body 10.

[0057] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
