The first thread and the second thread that link to each other are set gradually from the bottom up in the implant body outside to the pitch of second thread is less than the pitch of first thread, when the implant was assembled, because the width of first thread from bottom to top increases gradually, when the implant got into the alveolar bone, increase the perpendicular and horizontal pressure of alveolar bone to the implant, avoid the implant pine to take off, and the pitch of second thread is less than the pitch of first thread, when second thread and the equipment of alveolar bone, increase the area of contact of second thread and alveolar bone, further avoid the implant pine to take off, and implant body upper end one side still is provided with the constant head tank, after the implant is planted, drill on the alveolar bone of constant head tank one side, form the spacing groove on the alveolar bone of constant head tank one side, pack bone cement in constant head tank and spacing inslot, bone cement inserts into constant head tank and spacing groove in making spacing groove and constant head tank link to form the structure of stopping, avoid the implant body to take place to rotate and lead to the implant loose.

Preferably, a plurality of self-tapping grooves are further formed in the bottom of the implant body. The self-tapping groove is arranged at the bottom of the implant body, so that the implant can be conveniently implanted into the alveolar bone.

Preferably, the top in the implant body is also provided with an implant hole, and the implant body at the bottom of the implant hole is also provided with a third thread. After the abutment is assembled in the implantation hole, the abutment is fixed on the implant body by bolts penetrating through the abutment and the third thread assembly.

Preferably, the bottom of the positioning groove is communicated with one of the self-tapping grooves, and the adjacent self-tapping grooves are also connected through connecting holes. When bone cement is implanted, the bone cement enters the self-tapping grooves through the positioning grooves, and is adhered to the alveolar bone after entering the self-tapping grooves through the connecting holes, and the binding force between the bone cement and the alveolar bone is increased through the adhesion of the bone cement in the positioning grooves to the alveolar bone, so that the implant body is further prevented from rotating.

Compared with the prior art, the utility model has the following advantages:

1. when the implant is assembled, the width of the first thread is gradually increased from bottom to top, and when the implant enters the alveolar bone, the vertical and horizontal pressure of the alveolar bone on the implant is increased, so that the implant is prevented from loosening.

2. The pitch of the second thread is smaller than that of the first thread, and when the second thread is assembled with the alveolar bone, the contact area between the second thread and the alveolar bone is increased, so that the loosening of the implant is further avoided.

3. After the implant is planted, a hole is drilled in the alveolar bone at one side of the locating groove, a limit groove is formed in the alveolar bone at one side of the locating groove, bone cement is filled in the locating groove and the limit groove, after the bone cement is solidified, the bone cement is inserted into the locating groove and the limit groove to enable the limit groove and the locating groove to be connected into a whole to form a retaining structure, and the implant body is prevented from rotating to loosen the implant.
