Description

Technical Field

[0001] The present invention belongs to the field of dental implantation, and particularly relates to a method for immediate tooth implantation with autologous bone column transplantation. Background Art

[0002] Immediate tooth implantation is a technique of implanting an implant immediately at the original tooth extraction site after extracting the diseased tooth. Its principle is to utilize the fresh tooth extraction socket after tooth extraction. Before the alveolar bone is absorbed and remodeled, the implant is accurately implanted into the ideal position to reduce the absorption of the alveolar bone, shorten the toothless time, and improve the quality of life of the patient. Modern dental technology can achieve rapid tooth extraction and immediate implantation of artificial tooth roots, and it is usually applicable to patients under certain conditions, such as when the alveolar bone condition is good and the infection is well controlled;

[0003] During the preparation of the hole for the existing screw-type implant in the immediate tooth implantation process, according to the size and shape of the implant, the drill bit matching the implant machine is used to prepare the implant socket in the tooth extraction socket. Generally, starting from a drill bit with a smaller diameter, the implant socket is gradually enlarged until the appropriate diameter and depth are reached; this process will abrade a large amount of autologous bone or take a small amount of bone chips, resulting in bone waste. After the implant is implanted, a large amount of commercial bone products other than autologous bone are needed to fill and cover the implant area, increasing the additional cost of dental implants for patients. Moreover, since the bone products need 6 - 9 months to be completely absorbed, it will increase the overall repair time of the patients. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for immediate tooth implantation with autologous bone column transplantation to solve the problems of a large amount of autologous bone being abraded during the hole preparation process of the traditional immediate tooth implantation technique, resulting in bone waste, and the need to use a large amount of commercial bone products to fill and cover the implant area, with high costs and a long overall repair time as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A method for immediate tooth implantation with autologous bone column transplantation, comprising:

[0007] S1. Planning the implant site based on CT image data;

[0008] S2. Minimally invasive extraction of the diseased tooth and cleaning of the tooth extraction socket and surrounding granulation tissue;

[0009] S3. Using a positioning drill to position the implant site and then using a circumcision drill to drill a bone column at the implant site to form an implant socket;

[0010] S4. Sequentially using the implant drill bits to gradually enlarge the diameter of the implant socket until the selected implant model can be fully seated, and then implanting the implant;

[0011] S5, transplanting the bone column to the jump gap and bone defect;

[0012] S6. Screw on the healing base and suture the extraction wound without tension. The tooth can be extracted and implanted immediately.

[0013] Preferably, the rotation speed of the circular cutting machine is 900-1100 rpm.

[0014] Preferably, the length of the bone column is the length of the implant + 2-3 mm.

[0015] Preferably, after implanting the implant in step S4, the size of the jump gap and bone defect around the implant is observed. When the bone column obtained is not enough to fill the jump gap and bone defect, the bone column is drilled again at a position 3 mm away from the implant site where there is no adjacent tooth.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention uses a circumcision drill to drill the implant socket during the preparation of the hole for the implant extraction and implantation operation, and autologous bone columns are obtained during the process, thereby reducing bone waste. After the implant is implanted in the implant socket, the autologous bone columns are used to fill the jump gap and bone defect, and there is no need to use commercial bone products for filling, thereby reducing the use of commercial bone products other than autologous bones, saving patients the cost of using bone products, reducing the occurrence of postoperative complications and the resulting treatment costs, reducing adverse reactions after implantation, and shortening the time for later implant restoration.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] As attached Figure 1 , 2 and attached Figure 3 As shown:

[0026] Embodiment 1: This embodiment provides a method for extracting and implanting a tooth using autologous bone column transplantation, comprising:

[0027] S1. Planning implant sites based on CT imaging data;

[0028] S2, minimally invasive extraction of the affected tooth and cleaning of the extraction socket and surrounding granulation tissue;

[0029] S3, use the positioning drill to locate the implant site, and then use the ring cutting drill to drill the bone column at the implant site to form the implant socket;

[0030] S4. Use the implant drill bit to gradually expand the diameter of the implant cavity until the selected implant model can be fully positioned, and then implant the implant.

[0031] S5. Transplant bone columns to the jump gap and bone defect to avoid bone waste, reduce dependence on commercial bone, reduce costs and rejection risks, accelerate bone integration, and patients can enter the final repair stage faster;

[0032] S6. Screw on the healing base and suture the extraction wound without tension. The tooth can be extracted and implanted immediately.

[0033] Specifically, the rotation speed of the circular cutting machine is 900-1100 rpm.

[0034] Specifically, the length of the bone column is the implant length + 2-3 mm.

[0035] Specifically, after the implant is implanted in step S4, the size of the jump gap and bone defect around the implant is observed. When the bone column obtained is not enough to fill the jump gap and bone defect, another bone column is drilled at a position 3 mm away from the implant site where there are no adjacent teeth to retain the bone mass in the implant area, protect the bone density of the implant site, and improve the initial stability of the implant.

[0036] As can be seen from the above, the Figure 3 The leftmost one in the figure is a schematic diagram of the implant socket, the jump gap and the bone defect. The rightmost one is a schematic diagram after the implant and bone column transplantation. During the cavity preparation process, autologous bone columns are obtained, reducing bone loss during implantation. The autologous bone columns are used to fill the jump gap and the bone defect, reducing the use of commercial bone products other than autologous bone. Thus, the cost of bone products for patients is saved, the rejection and postoperative reactions of bone products other than autologous bone are reduced, and the occurrence of postoperative complications and the resulting treatment costs are reduced. The adverse reactions after implantation are reduced, the time for subsequent implant restoration is shortened, and the comfort of tooth implantation is increased.

[0037] Example 2:

[0038] Patient condition: The first mandibular molar is missing, and the bone density is normal (HU value 800 - 1200).

[0039] Operation steps:

[0040] CBCT is used to plan the bone harvesting site (3.5 mm away from the implant area);

[0041] A circumcision drill (1000 revolutions per minute) is used to harvest bone columns (length 12 mm, diameter 4 mm);

[0042] The bone columns are cut into 3 segments to fill the jump gap, and a collagen membrane is covered;

[0043] An implant (diameter 4.5 mm, length 10 mm) is implanted and restored 3 months after the operation.
