A plug type assembled multi-root dental implant structure based on SLM forming comprises a partial abutment integrated structure used for implanting a dental root of a dental socket implant and contacting with a gum and a dental crown part used for normally playing a chewing function. The integrated structure comprises a tooth, a part of an abutment and a connecting part of the abutment and the abutment, wherein the abutment is provided with a counter bore and at least one first positioning pin hole, and the tooth root is provided with a threaded hole and a second positioning pin hole corresponding to the first positioning pin hole; the screw passes through the counter bore and then screws into the threaded hole, and a positioning pin is arranged between the first positioning pin hole and the second positioning pin hole.
A plug pin type assembling multi-implant tooth structure forming method based on SLM forming comprises the following steps:
(1) Building a plurality of implant tooth models in a bolt type assembly mode according to teeth of a patient;
(2) After the implant model is obtained, the model divides the abutment and the tooth root part according to the number and the direction of the tooth roots, and the abutment and the tooth root part are divided into an integrated structure of the tooth roots and the abutment which is matched with the number of the tooth roots and a tooth crown part for normally playing the chewing function.
(3) After the part is printed, firstly, the tooth root and abutment integrated structure is cut off from the substrate, and the subsequent processing of the threaded hole and the positioning pin hole is completed.
(5) And assembling different root and abutment integrated structures.
The method for establishing the line implant model comprises the following steps:
firstly, CT scanning is carried out on teeth of a patient, after the CT scanning is carried out, layering processing is carried out on a CT file, the teeth part and the soft tissue part are divided according to different gray values, and after the CT image is processed, an implant model of the whole tooth is obtained.
The dental crown needs to be removed by a layer of thickness on the surface based on the original dental crown for later porcelain baking. And the tooth root and abutment integrated structure and the tooth crown are formed in printing. The fixation is realized by positioning pins and screws, namely, corresponding counter bores and positioning pin holes are processed in different integrated structures of the tooth root and the abutment.
Due to the principle of layered forming, the formed part of the metal 3D printing technology is not limited by the space complexity of the part, and any complex curved surface in the space can be formed. The Selective Laser Melting (SLM) is used as one of metal 3D printing, the elastic modulus and the mechanical property of the implant can be correspondingly changed by adjusting the microstructure of the implant with high precision, the matching with human bone tissues is realized, the biomechanical property is further improved on the basis of ensuring the proper physiological load, the manufacturing mode perfectly solves the problems that the traditional process is difficult to accurately copy the tooth root form and accurately control the pore size and the porosity of a porous titanium structure, and the generation of novel multiple implanted teeth which are individually customized for a patient becomes practical.
Example 1:
as shown in fig. 1,2,3, the present embodiment provides a plug type assembled multi-dental implant structure based on SLM molding, which comprises a near middle root and abutment integrated structure 1, a far middle root and abutment integrated structure 2, and a crown 3; a counter bore 5 and 1 first positioning pin hole 4 are arranged on the base station of the far middle tooth root and base station integrated structure 2, and a threaded hole 7 and a second positioning pin hole 6 corresponding to the first positioning pin hole are processed on the tooth root of the near middle tooth root and base station integrated structure 1; the inverted cone-shaped screw 9 is screwed into the threaded hole 7 after screwing through the counter bore 5, and a positioning pin 8 is arranged between the first positioning pin hole and the second positioning pin hole.

Example 2:
the embodiment provides a method for forming a plug-type assembled multi-dental implant structure of embodiment 1, the method is based on SLM forming, and the specific method includes the following steps:
1. first, the personalized implant is modeled according to the teeth of the patient.
A CT scan of the patient's teeth is first required. After CT scanning, the CT file is subjected to layering processing, and the tooth part and the soft tissue part are divided according to incompatible gray values. After the CT image is processed, a model of the whole tooth can be obtained.
2. After the tooth model is obtained, the tooth model is divided into the same number of tooth root and abutment integrated structures 1 or 2 and tooth crowns 3 according to the number of the tooth roots. The integrated tooth root is used for being implanted into a tooth socket after an affected tooth is removed and is responsible for fixing the whole tooth, and the abutment part is contacted with the tooth socket part to play a role in sealing the lower tooth root. The dental crown is used for normal chewing function.
Since the surface of the tooth finally needs porcelain, the inner dental crown needs to be removed by a layer of thickness on the surface based on the original dental crown for the subsequent porcelain.
3. After the model segmentation is completed, the positioning scheme of the part needs to be determined.
As can be seen from the structure in fig. 1, the required fixation is mainly realized by the positioning screw structure 9 and the positioning pin 8, and the stability between the integrated structures of different tooth roots and the abutment can be ensured by the synergistic action of the two structures, so that the two structures are prevented from moving relatively after being combined.
4. After the part is printed, firstly cutting the integrated structure of the tooth root and the base platform from the substrate, then processing all the threaded holes and the positioning pin holes, and finishing the processing process
5. And a screw passes through the counter bore and then is screwed into the threaded hole, and a positioning pin is arranged between the first positioning pin hole and the second positioning pin hole, so that different tooth roots and abutment integrated structures are assembled.
