Referring to fig. 1, 2, 3 and 4, the present invention provides a healing abutment 10.

In one embodiment of the present invention, the healing abutment 10 includes a main body portion 11 and a connecting portion 13; wherein, the main body 11 is defined to have two opposite ends, one end of the main body 11 is provided with a mounting structure 111, and the mounting structure 111 is used for connecting with the transfer rod 30; the connecting portion 13 is connected to an end of the main body 11 away from the connecting structure, and the connecting portion 13 is used for connecting with the implant 50.

In an embodiment of the present invention, the connecting portion 13 of the healing abutment 10 may be mainly used to connect with the implant 50 positioned in the gum so as to fix the healing abutment 10 in the mouth. The body part 11 can form a gum cuff above the implant 50 mainly by penetrating through the gum; meanwhile, the main body 11 can also be connected with the transfer rod 30 through a mounting structure 111 on one end of the main body, which is far away from the connecting part 13, so that the transfer rod 30 can be directly mounted on the main body 11 when the mold is taken in the mouth. The transfer bar 30 can be used mainly for positioning the position of the implanted implant 50, and the principle of operation of the transfer bar 30 is prior art, so it will not be described in detail herein.

The healing abutment 10 of the technical scheme of the invention is connected with the implant 50 through the connecting part 13, so that the implant 50 can be shaped by the healing abutment 10 after being implanted in the oral cavity of a patient, thereby forming a gum cuff. In addition, since the main body 11 of the healing abutment 10 is provided with the mounting structure 111 in this embodiment, the transfer rod 30 can be connected to the mounting structure 111. Compare in prior art the healing base station 10 need earlier dismantle this healing base station 10 when the mould is got in the mouth, later can install transfer rod 30 and carry out the preparation on implant 50 and plant the restoration die, healing base station 10 can directly install transfer rod 30 when the mould is got in the mouth in this scheme and carry out the preparation on main part 11 of this healing base station 10 and plant the restoration die, so make healing base station 10 need not to dismantle when the mould is got in the mouth to medical personnel's intensity of labour and patient's misery have been reduced.

Referring to fig. 2, fig. 3 and fig. 4, in an embodiment of the present invention, the main body 11 is provided with a mounting hole 113, the mounting hole 113 penetrates through an end surface of an end of the main body 11 away from the connecting portion 13, the mounting hole 113 is formed as a mounting structure 111, and the mounting hole 113 is used for mounting and fixing the transfer rod 30.

It will be appreciated that the mounting structure 111 is formed by the mounting hole 113 so that it can be formed by simply opening a hole in the main body portion 11. The structure of the mounting structure 111 can be simplified at this time, thereby making the mounting structure 111 easy to form; and simultaneously, the main body part 11 of the healing abutment 10 reduces part of the materials, thereby reducing the raw materials required for manufacturing the healing abutment 10 and reducing the manufacturing cost.

In one embodiment of the present invention, the wall of the mounting hole 113 is formed with an internal thread section.

It will be appreciated that the mounting hole 113 has an internally threaded section formed therein so that the transfer lever 30 and the main body portion 11 can be threadably connected. The threaded connection has the advantages of simplicity and reliability, so that the disassembly and assembly processes of the transfer rod 30 are simplified on the basis of ensuring the stability of fixing the transfer rod 30. Wherein the transfer lever 30 can be inserted through the transfer lever 30 by a locking member 70 having an externally threaded section and into the mounting hole 113 such that the transfer lever 30 is held in engagement by the locking member 70 and the main body 11. Of course, the transfer rod 30 may be a threaded post protruding from the bottom end thereof, and the threaded post may be inserted into the mounting hole 113 to achieve a threaded connection. In other embodiments, the mounting hole 113 may not be formed with an internal thread segment, and at this time, a portion of the transfer rod 30 may be inserted into the mounting hole 113 and fixed to the mounting hole 113 by tight fitting; alternatively, a magnetic block is embedded in the main body 11 and formed as the mounting structure 111, and at this time, the transfer rod 30 is also correspondingly provided with a magnetic block, so that the transfer rod 30 and the main body 11 are fixed by magnetic attraction.

In an embodiment of the present invention, the extension height of the internal thread on the wall of the mounting hole 113 is defined as H, and the following condition is satisfied: h is more than or equal to 2mm and less than or equal to 3 mm.

It can be understood that when the extension height H of the internal thread on the wall of the mounting hole 113 is less than 2mm, the height of the internal thread section is small, which affects the stability of the connection of the transfer lever 30 on the main body 11. When the extension height H of the internal thread on the wall of the mounting hole 113 is greater than 3mm, the convenience of forming the mounting hole 113 is affected, and the process of screwing or unscrewing the transfer lever 30 takes a certain time. Therefore, the extension height H of the internal thread on the hole wall of the mounting hole 113 is set to be not less than 2mm and not more than 3mm, which can take into account the fixing effect and the dismounting efficiency of the transfer rod 30, wherein the extension height H of the internal thread on the hole wall of the mounting hole 113 can be 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm and 3mm, and of course, any value in the above range can be taken.

Referring to fig. 5, in an embodiment of the invention, the connecting portion 13 is provided with a connecting hole 131, and the connecting hole 131 penetrates through an end surface of one end of the connecting portion 13 away from the main body portion 11 and is communicated with the mounting hole 113; the connection hole 131 is embedded with a fastener 133, and a portion of the fastener 133 passes through the mounting hole 113 and is used to connect with the implant 50.

It can be understood that the mounting hole 113 and the connection hole 131 are communicated, so that the two can be formed from one end of the healing abutment 10 to the other end thereof, thereby improving the convenience of manufacturing the healing abutment. Wherein, the fastener 133 may be a screw, so that not only the stability of the connection of the healing abutment 10 and the implant 50 can be ensured, but also the connection process of the two can be simplified. Of course, the present application is not limited thereto, and in other embodiments, the fastening member 133 may also be a clamping column, and in this case, the implant 50 is provided with a clamping hole for clamping and fixing. Alternatively, the connecting portion 13 and the implant 50 are directly fixed by magnetic attraction.

In an embodiment of the present invention, the connection hole 131 includes a first hole section 1311, a second hole section 1313, and a third hole section 1315, the first hole section 1311 communicating with the mounting hole 113; the second hole section 1313 is communicated with one end of the first hole section 1311 far away from the installation hole 113, the area of the cross section of the second hole section 1313 is smaller than that of the cross section of the first hole section 1311, and a supporting step 135 is formed at the joint of the second hole section 1313 and the first hole section 1311; the third hole section 1315 is communicated with one end, far away from the first hole section 1311, of the second hole section 1313, and one end, far away from the second hole section 1313, of the third hole section 1315 penetrates through the end face of one end, far away from the body part 11, of the connecting part 13; the fastener 133 is partially embedded in the first bore section 1311 and abuts the support step 135, and partially passes out of the second and

third bore sections

1313, 1315.

It can be understood that the supporting step 135 can limit the abutment of the fastening device 133, so that when the fastening device 133 is inserted into the implant 50, the fastening device 133 can be prevented from being screwed too deep to exert too much locking force on the healing abutment 10, and the healing abutment 10 can be prevented from being damaged; it is possible to prevent the fastener 133 from being screwed too shallow to affect the stability of the fixation of the healing abutment 10.

In one embodiment of the present invention, the cross-sectional areas of the first and

third bore sections

1311, 1315 are the same as the cross-sectional area of the mounting bore 113.

It will be appreciated that the first and

third hole segments

1311, 1315 are the same size as the mounting hole 113, so that the same mold or cutter may be used to form the same due to the uniformity of size, thereby further improving the convenience of manufacturing the healing abutment 10. Meanwhile, the arrangement is also realized, so that the fastener 133 can be inserted into the connecting hole 131 from the mounting hole 113 during mounting, or can be pulled out from the connecting hole 131 through the mounting hole 113 during dismounting, so that the dismounting and mounting of the fastener 133 are less convenient. Of course, the present application is not limited thereto, and in other embodiments, the cross-sectional areas of the first hole section 1311 and the third hole section 1315 may be smaller than the cross-sectional area of the mounting hole 113.

In an embodiment of the present invention, the area of the cross section of the main body portion 11 is larger than the area of the cross section of the connecting portion 13.

It can be understood that the healing base can form a certain size of the gum cuff through the body portion 11 having a relatively large cross-sectional area, and can be connected to the implant 50 more compactly through the connecting portion 13 having a relatively small cross-sectional area, thereby avoiding the need to occupy a large space inside the gum.

In one embodiment of the present invention, the healing abutment 10 further comprises a transition portion 15, defining the transition portion 15 having two ends disposed oppositely; the end of the main body 11 away from the mounting structure 111 is connected to one end of the transition portion 15, the connecting portion 13 is connected to the other end of the transition portion 15, and the cross-sectional area of the transition portion 15 gradually decreases in the direction of the main body 11 facing the connecting portion 13.

It is understood that the provision of the transition portion 15 enables the healing abutment 10 and the gum to be fitted more closely while increasing the abutment area between the healing abutment 10 and the gum, thereby further improving the stability of the fixation of the healing abutment 10. Wherein, when the healing abutment 10 comprises the transition part 15, the transition part 15 may be provided with a through hole 151 to communicate the first hole section 1311 and the installation hole 113.

Referring to fig. 4, in an embodiment of the present invention, projections of the main body 11, the transition portion 15 and the connecting portion 13 on a horizontal plane are all circular.

It can be appreciated that the main body portion 11, the transition portion 15, and the connecting portion 13 are all circular in shape, so that the healing abutment 10 is relatively small in size and occupies a small space in the gingiva. At this time, the periphery of the healing abutment 10 has a better consistency, so that the periphery of the healing abutment 10 can be attached to the gum less uniformly and tightly, thereby ensuring the stability of the fixation of the healing abutment 10. Meanwhile, the healing abutment 10 can be formed in a regular shape to facilitate manufacturing, and the directionality does not need to be considered in fixing, thereby facilitating the installation of the healing abutment 10. Of course, the present application is not limited thereto, and in other embodiments, the projections of the main body portion 11, the transition portion 15 and the connecting portion 13 on the horizontal plane are all square or other shapes.

In an embodiment of the present invention, the main body 11, the transition portion 15 and the connecting portion 13 are integrally formed.

It can be understood that the main body portion 11, the transition portion 15, and the connection portion 13 are integrated, so that the strength of several at the connection portion can be enhanced, thereby improving the overall strength of the healing abutment 10. Meanwhile, the healing abutment 10 can be manufactured by integral forming, thereby being beneficial to improving the production efficiency of the healing abutment 10.

The above description is only a preferred embodiment of the present invention, and is 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.
