In an embodiment of the present invention, theabutment connecting part 13 of thehealing abutment 10 is mainly used to connect with theimplant 300 positioned in the gum so as to fix the abutment body in the mouth. Theabutment body 11 may form a gum cuff above theimplant 300 by penetrating through the gum. Thescanning rod 30 can be mainly used for providing a positioning and marking function through themarking surface 31 when the oral cavity scanner scans the oral cavity. Thebase body 11 is detachably fitted with thescanning rod 30, so that when the gingiva is plastic, only thehealing base 10 of thehealing base assembly 100 is mounted on theimplant 300, and when the oral cavity is subjected to image information acquisition, thescanning rod 30 is directly mounted on thehealing base 10. Therotation preventing structure 50 is mainly used to limit the circumferential direction of thescanning rod 30, and reduce the possibility of the rotation of thescanning rod 30 relative to the basemain body 11.
Thehealing abutment 10 of thehealing abutment assembly 100 according to the technical scheme of the present invention is connected to theimplant 300 through theabutment connection part 13, so that theimplant 300 can be used to shape the gingiva by thehealing abutment 10 after being implanted in the oral cavity of a patient, thereby forming a gingival cuff. In addition, thehealing abutment assembly 100 of the present embodiment further includes ascanning rod 30, thescanning rod 30 is detachably sleeved on the abutmentmain body 11, that is, thescanning rod 30 is detachably connected to thehealing abutment 10. So that thescanning bar 30 can be detached from thehealing abutment 10 and only thehealing abutment 10 can be attached when shaping the gum. When the dental crown is prepared at a later stage and the image of the oral cavity of the patient needs to be scanned by thescanning rod 30, thescanning rod 30 may be directly attached to the abutmentmain body 11 of thehealing abutment 10. This eliminates the time-consuming step of first disassembling thehealing abutment 10 when installing thescan shaft 30, thereby reducing the labor intensity of the medical staff. Further, thehealing abutment assembly 100 of the present embodiment further includes ananti-rotation structure 50, and theanti-rotation structure 50 is disposed between thescan rod 30 and theabutment body 11. Through this rotation-proof structure 50 can prevent thatscanning rod 30 from rotating for base stationmain part 11 to improve the fixed stability of scanningrod 30, thereby guarantee when scanning the oral cavity through thisscanning rod 30 can fix a position more accurate and improve the scanning effect.
Referring to fig. 4 and 5, in an embodiment of the present invention, a first rotation-preventingsurface 51 is formed on an outer circumferential surface of the basemain body 11, a second rotation-preventingsurface 53 is formed on an inner circumferential surface of thescan rod 30, and the second rotation-preventingsurface 53 abuts against the first rotation-preventingsurface 51 and is formed as a rotation-preventingstructure 50.
It can be understood that the first rotation-preventingsurface 51 and the second rotation-preventingsurface 53 cooperate with the rotation-preventingstructure 50, so that the first rotation-preventingsurface 51 and the second rotation-preventingsurface 53 are respectively formed on the basemain body 11 and thescanning rod 30 by cutting, and excessive structures are not required to be additionally arranged, so that the rotation-preventingstructure 50 is simpler and the rotation-preventingstructure 50 is convenient to form. Of course, the present invention is not limited to this, and in other embodiments, a stopper may be formed on the outer circumferential surface of the basemain body 11, a stopper groove is correspondingly formed on the inner circumferential surface of thescan lever 30, and the stopper abuts against the stopper groove to form therotation preventing structure 50. Alternatively, the outer peripheral surface of the basemain body 11 and the inner peripheral surface of thescanning rod 30 are formed with a stopper groove, and by inserting a stopper, a part of the stopper is located in the stopper groove of the basemain body 11 and a part of the stopper is located in the stopper groove of thescanning rod 30.
In an embodiment of the present invention, the number of the first rotation-stoppingsurfaces 51 is plural, and the plural first rotation-stoppingsurfaces 51 are distributed at regular intervals around the center of the basemain body 11; the number of the second rotation stop surfaces 53 is plural, and one second rotation stopsurface 53 abuts against one first rotation stopsurface 51.
It can be understood that the number of the first rotation-preventingsurfaces 51 and the second rotation-preventingsurfaces 53 is plural, so that the limiting effect of the rotation-preventingstructure 50 on the circumferential direction of the transfer lever can be improved. At the same time, the contact area between the transfer lever and thebase body 11 is increased by the contact between the first rotation stop surfaces 51 and the second rotation stop surfaces 53, and the stability of the transfer lever attached to thehealing base 10 can be improved.
In an embodiment of the present invention, the first rotation stop surfaces 51 and the second rotation stop surfaces 53 are disposed parallel to the vertical plane.
It can be understood that, the arrangement is such that the first rotation-stoppingsurface 51 and the second rotation-stoppingsurface 53 are directly cut and arranged by the cutter along the vertical direction, so that the angle of the cutter can be conveniently controlled when the cutter is cut and arranged, and the convenience of forming the first rotation-stoppingsurface 51 and the second rotation-stoppingsurface 53 can be improved. Of course, the present invention is not limited to this, and in other embodiments, the plurality of first rotation stop surfaces 51 may be provided on the basemain body portion 11 so as to be inclined downward toward the outside of the basemain body portion 11. The second rotation stopsurface 53 is matched and abutted with the first rotation stopsurface 51.
In an embodiment of the present invention, the plurality of firstrotation stopping surfaces 51 are sequentially connected, the plurality of secondrotation stopping surfaces 53 are sequentially connected, and projections of the plurality of firstrotation stopping surfaces 51 and the plurality of secondrotation stopping surfaces 53 on a horizontal plane are regular polygon shapes.
It can be understood that the projections of the first rotation stop surfaces 51 and the second rotation stop surfaces 53 on the horizontal plane are regular polygon shapes, so that the side peripheral surface of the basemain body 11 has better consistency, and at this time, the installation directionality does not need to be considered too much when thescanning rod 30 is sleeved on the basemain body 11, the alignment precision of thescanning rod 30 and the base main body is reduced, and the installation convenience of thescanning rod 30 is improved. Meanwhile, the arrangement also facilitates the molding process of the basemain body part 11 due to the better consistency of the peripheral sides. The projection of the first rotation-stoppingsurfaces 51 on the horizontal plane is in a regular polygon shape, which means that the projection lines of the first rotation-stoppingsurfaces 51 connected in sequence on the horizontal plane enclose and form a regular polygon shape. Similarly, the projections of the plurality of secondrotation preventing surfaces 53 on the horizontal plane are regular polygon shapes, which means that the projection lines of the plurality of secondrotation preventing surfaces 53 connected in sequence on the horizontal plane enclose and form the regular polygon shapes. In addition, the present invention is not limited to this, and in other embodiments, projections of the plurality of firstrotation preventing surfaces 51 and the plurality of secondrotation preventing surfaces 53 on a horizontal plane may be in a non-regular polygon shape.
Referring to fig. 3, fig. 4 and fig. 5, in an embodiment of the present invention, the basemain body 11 includes abase 111 and aconvex pillar 113, thebase 111 is connected to thebase connecting portion 13; theconvex column 113 is connected with one end of thebase seat 111 departing from the basestation connecting part 13, the area of the cross section of theconvex column 113 is smaller than that of thebase seat 111, and a first rotation stopsurface 51 is formed on the outer peripheral surface of theconvex column 113; thescanning rod 30 is sleeved on the protrudingcolumn 113 and abuts against thebase 111.
It can be understood that theseat 111 can limit thescanning rod 30 in the abutting manner, so that thescanning rod 30 is accurately sleeved at the predetermined installation position. Thescanning rod 30 is sleeved on theconvex column 113 with a relatively small cross section area, so that thescanning rod 30 and thehealing abutment 10 can be mounted more compactly, and the occupation of thehealing abutment assembly 100 to the space in the oral cavity is reduced, thereby avoiding discomfort to a patient. It should be noted that, the present application is not limited thereto, and in other embodiments, the area of the cross section of theseat 111 and the area of the cross section of the protrudingpillar 113 may also be the same, and both may be set relatively smaller to avoid occupying too much space in the oral cavity.
In an embodiment of the present invention, a guidinginclined plane 115 is formed on an outer circumferential surface of one end of theconvex column 113 departing from thebase 111, and the guidinginclined plane 115 guides thescanning rod 30 to be sleeved on theconvex column 113.
It can be understood that the guidinginclined plane 115 has a guiding function on the sheath of thescanning rod 30, and can guide thescanning rod 30 to be gradually and accurately sheathed on theconvex column 113 of the base stationmain body part 11. Thus, the requirement of the alignment precision between the scanningrod 30 and theconvex column 113 of the basemain body 11 during installation is reduced, and the convenience of installation of thescanning rod 30 is improved.
In an embodiment of the present invention, the inner peripheral surface of thescan rod 30 is formed with a matchinginclined surface 33, and the matching inclinedsurface 33 is adapted to the guidinginclined surface 115 and abuts against the guidinginclined surface 115.
It can be understood that, by the engagement inclinedsurface 33 abutting against the guide inclinedsurface 115, the abutting area of thescanning lever 30 and theboss 113 of the basemain body portion 11 is increased, and thus the stability of fixing thescanning lever 30 can be improved.
In an embodiment of the invention, adeformation groove 35 is formed at one end of thescanning rod 30 sleeved on theconvex pillar 113, thedeformation groove 35 penetrates through the inner side and the outer side of thescanning rod 30, thedeformation groove 35 extends along a direction of thescanning rod 30 facing theseat 111, and further penetrates through the surface of thescanning rod 30 abutting against theseat 111.
It can be understood that thedeformation groove 35 is provided to make the inner diameter of thescanning rod 30 relatively small, and when thescanning rod 30 is sleeved on theconvex pillar 113 of the base platformmain body 11, thedeformation groove 35 makes thescanning rod 30 deformed accordingly to facilitate the nesting of thescanning rod 30. After thescanning rod 30 is sleeved on theconvex column 113, thescanning rod 30 can be restored to the original state to tightly limit theconvex column 113. Therefore, even if thescan rod 30 is sleeved, the stability of fixing thescan rod 30 is improved. The number of thedeformation grooves 35 may be multiple, and the deformation grooves are distributed around the center of thescanning rod 30 at uniform intervals, so that each circumferential position of thescanning rod 30 is uniformly deformed, and theconvex columns 113 are uniformly abutted.
Referring to fig. 2, fig. 3 and fig. 4, in an embodiment of the present invention, the basemain body 11 is provided with aconnection hole 117, theconnection hole 117 extends along a direction of the basemain body 11 facing thebase connecting portion 13, thescan rod 30 is provided with a mountinghole 37, and the mountinghole 37 is disposed opposite to theconnection hole 117; thehealing abutment 10 further includes alock 70, thelock 70 is inserted through the mountinghole 37 and into thecoupling hole 117, and thelock 70 and theabutment body 11 cooperate to hold thescan shaft 30.
It can be understood that theconnection hole 117 and the mountinghole 37 provide a space for accommodating thelock 70, so that thelock 70 can be embedded, and thus when thescan rod 30 is mounted on the base platformmain body 11, thelock 70 is embedded in the mountinghole 37, and the influence of thelock 70 on the oral cavity wall can be reduced. The lockingmember 70 may be a screw, and an inner thread section may be formed on a hole wall of theconnection hole 117. Of course, in other embodiments, the bottom end of thescanning rod 30 is directly protruded with a locking column, and theconvex column 113 of thebase body 11 is provided with a locking hole matching with the locking column, so that thescanning rod 30 and the base body can be locked and fixed. In addition, in order to further facilitate the connection between theabutment connecting part 13 and the implant rod, a through hole communicating with the mountinghole 37 may be provided in the abutment connecting part 13 (in this case, the mountinghole 37 penetrates through thebase 111 and thepost 113 of the abutment body 11), and thehealing abutment assembly 100 may further include afastener 90, wherein thefastener 90 is inserted into the through hole from the mountinghole 37 and is inserted into theimplant 300 after penetrating through the through hole, so that thefastener 90 and theimplant 300 cooperate to clamp and fix theabutment connecting part 13. In this case, thefastening member 90 may be a screw, and a corresponding threaded hole is formed in theimplant 300. Or the fasteningmember 90 may be a fastening column, and a fastening hole matched with the fastening column is correspondingly formed in theimplant 300. And in order to further improve the stability of thehealing base station 10 and theimplant 300, thehealing base station 10 may further include a basestation transition part 15, two ends of the basestation transition part 15 are respectively connected to the base stationmain body part 11 and the base body connecting part, and in the direction of the base stationmain body part 11 facing the base body connecting part, the area of the cross section of the basestation transition part 15 is gradually reduced, so that the basestation transition part 15 and the gum are in inclined plane fit and can be closely attached and increase the abutting area of the base station transition part and the gum, thereby improving the stability of thehealing base station 10 in fixation. At this time, theabutment transition portion 15 may be provided with a through hole communicating the mountinghole 37 and the through hole for thefastener 90 to pass through to be placed in the through hole.
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.
