Referring to fig. 1, fig. 2 and fig. 3, the present invention provides a healing abutment 100.

In one embodiment of the present invention, the healing abutment 100 comprises an abutment body 10 and a protective sheath 30; the abutment body 10 comprises a main body section 11, a gum matching section 13 and a connecting section 15, wherein one end of the gum matching section 13 is connected to one end of the main body section 11, one end of the connecting section 15 is connected to one end of the gum matching section 13, which is far away from the main body section 11, the other end of the connecting section 15 is used for being connected with the implant 300, and the area of the cross section of the gum matching section 13 is gradually reduced in the direction that the main body section 11 faces the connecting section 15; the protective sheath 30 is sleeved on the main body section 11.

In an embodiment of the present invention, the upper end of the main body section 11 of the abutment body 10 is exposed to the outside, and is mainly used for installing the protective sheath 30. The gum fitting section 13 is mainly used to increase the abutment area of the gum, thereby improving the stability of the abutment body installation. Wherein, the area of the cross section of the gum matching section 13 is gradually reduced, and the lateral periphery of the gum matching section 13 can be an inclined plane or an arc-shaped surface. The connecting section 15 is mainly used for connecting with the implant 300 positioned in the gum so as to fix the abutment body 10 in the mouth. The protective sheath 30 is mainly used to cover the outer side of the main body 11, and serves to isolate the external object from the gingiva at the lower end of the healing abutment 100.

The healing abutment 100 of the technical scheme of the invention is connected with the implant 300 through the connecting section 15, so that the implant 300 can be beneficial to the healing abutment 100 to shape the gingiva after being implanted into the oral cavity of a patient, thereby forming a gingival cuff. In addition, because the area of healing base station 100's gum cooperation section 13 cross section is the diminishing setting gradually in main body segment 11 towards the direction of linkage segment 15 in this scheme, can increase the area of contact of healing base station 100 and gum to make healing base station 100 inseparabler with the gum laminating, thereby can improve the fixed stability of this healing base station 100, in order to guarantee the moulding effect to the gum. Further, the healing abutment 100 in this scheme still includes protective sheath 30, can locate the main part section 11 of healing abutment 100 through this protective sheath 30 and play the effect of keeping apart the foreign object to the gum that is located healing abutment 100 lower extreme for the foreign object is difficult to and the gum that heals abutment 100 lower extreme takes place to contact, thereby has reduced and has aroused the oral cavity and has caused the possibility of infecting, further guarantees the moulding effect to the gum.

Referring to fig. 2 and fig. 4, in an embodiment of the present invention, the main body 11 includes a base 111 and a convex pillar 113, the base 111 is connected to an end of the gum matching section 13 away from the connecting section 15; the convex column 113 is connected to the surface of the base 111 departing from the gum matching section 13, and the area of the cross section of the convex column 113 is smaller than that of the base 111; the protection sleeve 30 is sleeved on the convex column 113 and abuts against the base 111.

It can be understood that the base 111 can limit the abutting of the protective sleeve 30, and the protective sleeve 30 is accurately sleeved on the preset mounting position to achieve a good isolation protection effect. And the convex column 113 with the relatively smaller area of the cross section is sleeved with the protective sleeve 30, so that the connection between the protective sleeve 30 and the base body is more compact, and the occupation of the space in the oral cavity is reduced. Of course, the present application is not limited thereto, and in other embodiments, the area of the cross section of the base 111 and the area of the cross section of the protruding pillar 113 may also be the same, and both may be set relatively smaller to avoid occupying too much space in the oral cavity.

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

It can be understood that the protective sheath 30 has a cylindrical structure with openings at both ends, so that the shape and structure of the protective sheath 30 are relatively simple, and the convenience of manufacturing the protective sheath 30 can be improved. Meanwhile, the protective sleeve 30 is provided with a side peripheral wall, so that the use of raw materials required in the manufacturing process is relatively small, and the manufacturing cost of the protective sleeve 30 is favorably reduced. Of course, the present application is not limited thereto, and in other embodiments, the protective sheath 30 may also include a sheath top wall and a sheath side wall, wherein the sheath side wall is connected to the sheath top wall and is disposed around the circumference of the sheath top wall to provide better isolation protection.

In an embodiment of the present invention, a distance between an opening of one end of the protection cover 30 away from the base 111 and the base 111 is greater than a distance between an end surface of one end of the protruding pillar 113 away from the base 111 and the base 111.

It can be understood that the height of the protective sheath 30 is higher than that of the protruding column 113, which can reduce the possibility that foreign objects enter the protective sheath 30 and further between the protective sheath 30 and the protruding column 113, thereby being more beneficial to ensuring the cleanness of the place to better protect the oral cavity. Of course, the present application is not limited thereto, and in other embodiments, the height of the protection sleeve 30 is the same as the height of the protruding pillar 113.

Referring to fig. 2, fig. 3 and fig. 4, in an embodiment of the present invention, the inner wall of the protection sleeve 30 is provided with an abutting rib 31, the abutting rib 31 is circumferentially disposed along the protection sleeve 30, and the abutting rib 31 abuts against a surface of the convex pillar 113 departing from the base 111.

It can be understood that, through the butt muscle 31 butt in projection 113, can further establish the in-process to the cover protective sheath 30 and carry on spacingly to further guarantee that the accurate cover of protective sheath 30 locates and predetermines the mounted position. Meanwhile, through the arrangement of the abutting ribs 31, the protective sleeve 30 can be fixed by inserting one locking piece 500, so that a connecting structure is not required to be arranged on the protective sleeve 30, and the structure of the protective sleeve 30 is simplified. Specifically, the locking member 500 is inserted into the protruding column 113 through the protection sleeve 30, and the locking member 500 and the protruding column 113 cooperate to clamp and fix the protection sleeve 30. In this case, the locking member 500 may be a screw, and a threaded hole may be formed in the main body 11 to be engaged therewith. Of course, the locking member 500 and the protruding pillar 113 of the main body 11 may also be magnetically attracted, that is, magnetic blocks that attract each other are embedded in each of them. Alternatively, the protective sheath 30 may be directly adhered to the protruding column 113 of the main body segment 11 by glue.

Referring to fig. 4, in an embodiment of the present invention, the abutting rib 31 separates the inner space of the protection cover 30 into a first hole section 33 and a second hole section 35 which are communicated with each other, the first hole section 33 penetrates through an end surface of one end of the protection cover 30 facing away from the base 111, the second hole section 35 penetrates through an end surface of one end of the protection cover 30 facing the base 111, and a cross-sectional area of the second hole section 35 is larger than a cross-sectional area of the first hole section 33.

It will be appreciated that the second bore section 35 is larger than the first bore section 33 such that the second bore section 35 has a larger cross-section. At this time, the possibility of friction caused by contact with the side surface of the protruding pillar 113 can be reduced (i.e. a certain gap is formed between the hole wall of the second hole section 35 and the protruding pillar 113), so that the protective sleeve 30 can be conveniently sleeved on the protruding pillar 113. Meanwhile, the second hole section 35 is larger than the first hole section 33, so that the two ends of the protection sleeve 30 have differences, and the protection sleeve 30 is sleeved on the convex column 113 to have an installation prompting function, so that an installer can conveniently sleeve one end of the protection sleeve 30, which is provided with the second hole section 35, on the convex column 113 to install the protection sleeve 30 in place at one time.

In an embodiment of the present invention, a first inclined surface 1131 is formed at a connection between a surface of the convex pillar 113 facing away from the base 111 and a side circumferential surface of the convex pillar 113, a second inclined surface 37 is formed at a connection between a surface of the abutting rib 31 facing the second hole section 35 and a hole wall of the second hole section 35, and the second inclined surface 37 abuts against the first inclined surface 1131.

It can be understood that the first inclined surface 1131 can guide the protection sleeve 30 to be inserted into the convex column 113 when the protection sleeve 30 is sleeved on the convex column 113, so as to reduce the requirement of the alignment precision between the protection sleeve 30 and the convex column 113 during installation. When the protection sleeve 30 is sleeved in the convex column 113, the first inclined surface 1131 and the second inclined surface can be abutted, and the position of the protection sleeve 30 in the horizontal direction can be adjusted through the matching of the first inclined surface 1131 and the second inclined surface, so that the possibility of deviation of the protection sleeve 30 in the horizontal direction is reduced, and the installation and insertion of a subsequent fastener 700 are influenced. Meanwhile, the contact area between the protection sleeve 30 and the convex column 113 is also increased by the contact between the first inclined surface 1131 and the second inclined surface, so that the stability of the installation of the protection sleeve 30 can be improved.

In an embodiment of the present invention, the outer peripheral surface of the protection cover 30 and the surface of the protection cover 30 away from the base 111 are smoothly transited.

It can be understood that the outer peripheral surface of the protective sheath 30 and the surface of the protective sheath 30 departing from the base 111 are in smooth transition, so that no edge is formed at the position, and at this time, the possibility of scratching the oral cavity wall by the protective sheath 30 can be reduced, thereby improving the safety of the healing abutment 100 in the using process.

In an embodiment of the present invention, the outer periphery of the protective sheath 30 and the side periphery of the base 111 are coplanar.

It can be understood that the outer peripheral surface of the protective sheath 30 and the side peripheral surface of the base 111 are located on the same plane, i.e. the protective sheath can play a better role of isolating the external object to the gingiva healing the lower end of the abutment 100, and at the same time, the possibility of the protective sheath 30 causing the extrusion damage to the gingiva around the abutment body 10 is reduced. Of course, the present application is not limited thereto, and in other embodiments, the outer circumference of the protection cover 30 may be slightly larger than the side circumference of the base 111.

Referring to fig. 2, in an embodiment of the present invention, the projections of the protective sheath 30, the main body section 11, the gum engaging section 13 and the connecting section 15 on a horizontal plane are all circular.

It can be appreciated that the protective sheath 30, the body section 11, the gum engaging section 13, and the connecting section 15 are all circular in shape so that the healing abutment 100 is relatively small in volume and reduces the space occupied within the gum. At this time, the periphery of the abutment body 10 also has better consistency, so that the periphery of the abutment body 10 can be attached to the gum less uniformly and tightly, thereby ensuring the stability of the abutment body 10. Meanwhile, by such an arrangement, the shapes of the base body 10 and the protective sleeve 30 are regular, so that the forming and manufacturing are convenient, and the directionality does not need to be considered when the base body 10 and the protective sleeve 30 are fixed, thereby being beneficial to improving the convenience of mounting the base body 10 and the protective sleeve 30. Of course, the present application is not limited thereto, and in other embodiments, the projections of the protective sheath 30, the main body section 11, the gum engaging section 13 and the connecting section 15 on the horizontal plane are all circular and the projections on the horizontal plane are all square or other shapes. Wherein the connecting section 15 and the implant 300 can be locked and fixed by a fastener 700, the fastener 700 is inserted through the connecting section 15 and into the implant 300. In this case, the fastening member 700 may be a screw, and in order to facilitate the installation and replacement of the pair of fastening members 700, the abutment body may be formed with a through hole penetrating the body section 11, the gum fitting section 13, and the connection section 15, an upper section of the through hole being formed with an internal thread connected to the locking member 500, and a lower section receiving the fastening member 700.

In an embodiment of the present invention, the main body section 11, the gum engaging section 13 and the connecting section 15 are an integral structure.

It can be understood that the main body section 11, the gum fitting section 13, and the connection section 15 are integrated, so that the strength of the several at the connection can be enhanced, thereby improving the overall strength of the abutment body 10. Meanwhile, by such an arrangement, the base body 10 can be manufactured by integral forming, thereby being beneficial to improving the production efficiency of the base body 10.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
