It can be understood that the first rotation-preventing surface 51 and the second rotation-preventing surface 53 cooperate with the rotation-preventing structure 50, so that the first rotation-preventing surface 51 and the second rotation-preventing surface 53 are respectively formed on the base main body 11 and the scanning rod 30 by cutting, and excessive structures are not required to be additionally arranged, so that the rotation-preventing structure 50 is simpler and the rotation-preventing structure 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 base main body 11, a stopper groove is correspondingly formed on the inner circumferential surface of the scan lever 30, and the stopper abuts against the stopper groove to form the rotation preventing structure 50.

At the same time, the contact area between the transfer lever and the base 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 the healing 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-stopping surface 51 and the second rotation-stopping surface 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-stopping surface 51 and the second rotation-stopping surface 53 can be improved.

Meanwhile, the arrangement also facilitates the molding process of the base main body part 11 due to the better consistency of the peripheral sides. The projection of the first rotation-stopping surfaces 51 on the horizontal plane is in a regular polygon shape, which means that the projection lines of the first rotation-stopping surfaces 51 connected in sequence on the horizontal plane enclose and form a regular polygon shape. Similarly, the projections of the plurality of second rotation preventing surfaces 53 on the horizontal plane are regular polygon shapes, which means that the projection lines of the plurality of second rotation 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 first rotation preventing surfaces 51 and the plurality of second rotation preventing surfaces 53 on a horizontal plane may be in a non-regular polygon shape.

It can be understood that the seat 111 can limit the scanning rod 30 in the abutting manner, so that the scanning rod 30 is accurately sleeved at the predetermined installation position. The scanning rod 30 is sleeved on the convex column 113 with a relatively small cross section area, so that the scanning rod 30 and the healing abutment 10 can be mounted more compactly, and the occupation of the healing 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 the seat 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.

Thus, the requirement of the alignment precision between the scanning rod 30 and the convex column 113 of the base main body 11 during installation is reduced, and the convenience of installation of the scanning rod 30 is improved.
In an embodiment of the present invention, the inner peripheral surface of the scan rod 30 is formed with a matching inclined surface 33, and the matching inclined surface 33 is adapted to the guiding inclined surface 115 and abuts against the guiding inclined surface 115.

It can be understood that the deformation groove 35 is provided to make the inner diameter of the scanning rod 30 relatively small, and when the scanning rod 30 is sleeved on the convex pillar 113 of the base platform main body 11, the deformation groove 35 makes the scanning rod 30 deformed accordingly to facilitate the nesting of the scanning rod 30. After the scanning rod 30 is sleeved on the convex column 113, the scanning rod 30 can be restored to the original state to tightly limit the convex column 113. Therefore, even if the scan rod 30 is sleeved, the stability of fixing the scan rod 30 is improved. The number of the deformation grooves 35 may be multiple, and the deformation grooves are distributed around the center of the scanning rod 30 at uniform intervals, so that each circumferential position of the scanning rod 30 is uniformly deformed, and the convex columns 113 are uniformly abutted.
