Therefore, it can be understood that the description of this part is for the above purpose, and not for the acknowledgement of the prior art.

[0003] The tooth loss rate of middle-aged and old people is very common, and the average number of remaining teeth of the population in the age group of 65-74 is 20.97 / 32. With the improvement of per capita disposable income, oral implant repair is in a rapid development stage and has become the primary repair method for tooth loss in middle-aged and old people. Among the people aged 65-74, 86% have tooth loss, the proportion of full-mouth edentulism is 4.5%, and the proportion of edentulous repair is 63.2%.

[0004] In the field of oral medical repair, dental implant as an effective treatment method plays an increasingly important role. Dental implant is a kind of treatment method for replacing natural tooth root by implanting implant body similar to tooth root in the case of single tooth loss or tooth defect, and restoring the function of tooth chewing by installing denture. Dental implant refers to a kind of pure titanium metal with high compatibility with human bone, which is designed and manufactured into a cylindrical body or other shape similar to tooth root through precise design, and is implanted into the alveolar bone of the edentulous area through surgical operation. From the preparation of implantation cavity to the implantation of implant body, and finally after 1-3 months according to the situation of bone integration in the oral cavity, the previous covering screw is removed, the abutment is installed, and the full ceramic or porcelain tooth crown is made on the artificial tooth root, which completes the oral implantation. The implant body platform is also called artificial tooth root, which is implanted into the upper and lower jaw bones of the human body through surgical operation, and the device for installing the prosthetic tooth is installed on the upper part after the surgical wound is healed. The implant body needs to rely on bone drill when implanted, and different bone drills are used for different depths. The existing implant body has a conical structure, and in order to better combine with the alveolar bone and increase the stability, the alveolar bone also needs to be drilled into a drill hole matched with the implant body.

[0043] In order to make the purpose, technical scheme and advantage of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments are a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor are within the protection scope of the utility model.

[0044] As Figures 1 to 6 The utility model discloses an implant tooth bone chip drill for alveolar bone, including: straight pole handle 1 is set with drill head 2 to the front end of handle 1, the tail end of handle 1 is set with the connecting portion 11 of the dental mobile phone equipment of external equipment adaptation, drill head 2 includes first cutting part 21 and second cutting part 22, first cutting part 21 and second cutting part 22 are coaxial, the cutting radius of first cutting part 21 is different with the cutting radius of second cutting part 22. The implant tooth bone chip drill for alveolar bone provided by the utility model embodiment is described in detail below.

[0045] As Figures 2 to 7As shown in the utility model embodiment, the first cutting part 21 is located at the end of the drill body 2, and the second cutting part 22 is arranged at the position close to the root of the drill body 2; the cutting radius of the first cutting part 21 is smaller than the cutting radius of the second cutting part 22. In order to smoothly cut, the cutting slope angle of the first cutting part 21 and the second cutting part 22 is 45°-75°.

[0046] As Figure 2 and Figure 5 As shown in the utility model embodiment, the drill body 2 is provided with a bone chip storage cavity 20; the bone chip storage cavity 20 is communicated with the side wall of the drill body 2. Further, the first cutting part 21 is further provided with a bone chip guide groove 29 arranged along the axial direction of the drill body 2, and the bone chip guide groove 29 is communicated with the bone chip storage cavity 20. In the drilling process, the bone chips cut by the end of the drill body 2 are collected in the bone chip storage cavity 20 through the bone chip guide groove 29. When implanting teeth, after implanting the implant body into the alveolar bone, the gap between the implant body and the surrounding tooth socket bone wall often needs to be implanted with bone powder (bone replacement material), and the autologous bone chip has the best osteogenesis effect and the fastest osteogenesis speed. The utility model embodiment can take the bone after the cone-shaped cavity hole, and the autologous bone chip can be directly taken out while drilling, and filled into the gap between the implant body and the surrounding bone, which can have a good osteogenesis effect, and at the same time, the use of other allogeneic bone, xenogeneic bone or artificial synthetic bone is saved, and the cost is saved.

[0047] As Figure 2 , Figures 5 to 7 As shown in the utility model embodiment, between the first cutting part 21 and the second cutting part 22, the circumferential outer surface of the drill body 2 is provided with a spiral-shaped chip removal groove 23 along the axial direction of the drill body 2, and the chip removal groove 23 is communicated with the bone chip storage cavity 20. The bone chips cut by the first cutting part 21 and the second cutting part 22 are collected and stored in the bone chip storage cavity 20 through the chip removal groove 23.

[0048] As Figures 4-7 As shown in the utility model embodiment, in order to be more beneficial to cutting, the cutting edge of the first cutting part 21 is spirally distributed. The cutting edge is spirally distributed, which can form a recess on the outer periphery of the opening more quickly, and save the subsequent trimming time. Further, in order to improve the cutting efficiency, the first cutting part 21 comprises a plurality of cutting edges, and the plurality of cutting edges are uniformly distributed along the circumferential direction of the cutting edge part.

[0049] As Figures 1-5As shown in the drawings, in order to effectively avoid the positioning drill 4 from drilling too deep into the alveolar bone 8 and damaging the alveolar bone 8, a limiting stop ring 26 is sleeved on the drill body 2. The height of the limiting stop ring 26 defines the depth of the drill body 2 into the alveolar bone 8. Different heights of the limiting stop ring 26 can be replaced according to different depth requirements.

[0050] As shown in the drawings, Figures 1-5 As shown in the drawings, in order to effectively avoid the positioning drill 4 from drilling too deep into the alveolar bone 8 and damaging the alveolar bone 8, an abutting boss 25 is arranged at the bottom of the drill body 2. In the case where there is no suitable limiting stop ring 26, the drilling depth of the positioning drill 2 is effectively limited by the abutting boss 25. Further, the outer diameter of the abutting boss 25 is larger than the outer diameter of the drill 2. The outer diameter of the abutting boss 25 is 4mm-5mm. In order to effectively ensure the flexibility of drilling, the thickness t of the abutting boss 25 is 1mm-2mm, preferably 1.5mm.

[0051] As shown in the drawings, Figures 5-8 As shown in the drawings, in order to cooperate with the implant implanting into the alveolar bone 8, the cutting radius difference between the first cutting part 21 and the second cutting part 22 is 0.5mm-1mm. By the first cutting part 21 and the second cutting part 22 with different radii, the alveolar bone 8 can be drilled into a shape close to a cone of the implant 7, which is more conducive to the implantation of the conical implant 7.

[0052] As shown in the drawings, Figures 1-9 As shown in the drawings, in order to cooperate with the positioning of the drill body 2, a positioning drill 27 coaxial with the handle is arranged at the center of the head of the drill body 2, and the positioning drill 27 is higher than the drill body 2. The outer diameter d of the positioning drill is 1.5mm-2mm.

[0053] In summary, the implant tooth alveolar bone bone debris drill provided by the implant tooth alveolar bone bone debris drill can drill the alveolar bone into a shape close to a cone of the implant, which is more conducive to the implantation of the conical implant, especially can be applied to the tooth with no obvious periapical inflammation, and can be immediately extracted and immediately implanted under local anesthesia. The positioning drill on the drill body can effectively ensure the central positioning of the ring cutting drill body around the positioning drill. The bone debris storage cavity can effectively collect bone debris and avoid bone debris loss.
