Problems solved by technology

[0004]Currently, most of the traditional implants used for immediate implant surgery are conical or columnar, which do not match the shape of the extraction socket, and it is difficult to guarantee the initial stability. Relying on the part where the implant depth exceeds the original extraction socket, the operator needs to use a special implant techniqu

Embodiment 1

[0042] Such as figure 1 , as shown in 2 and 3, this embodiment provides a plug-type assembled multi-root dental implant structure based on SLM molding, including an integrated structure 1 of the mesial tooth root and the abutment, an integrated structure 2 of the distal tooth root and the abutment, and The crown 3 has three parts; the integrated structure of the distal root and the abutment 2 has a countersunk hole 5 and a first positioning pin hole 4 on the abutment, and the integrated structure of the mesial tooth root and the abutment 1 has a threaded hole 7 on the root And the second positioning pin hole 6 corresponding to the first positioning pin hole; the inverted taper screw 9 is screwed into the threaded hole 7 after passing through the countersunk hole 5, and the positioning is installed between the first positioning pin hole and the second positioning pin hole pin 8. another example Figure 5 , 6, a rectangular groove is set between the countersunk hole 5 and the ...

Embodiment 2

[0044] This embodiment provides the molding method of plug-type assembled multi-root dental implant structure in Embodiment 1. The method is based on SLM molding. The specific method includes the following steps:

[0045] 1. First, it is necessary to establish a personalized implant model according to the patient's teeth.

[0046] First, a CT scan of the patient's teeth is required. After the CT scan, the CT file is layered, and the tooth part and the soft tissue part are divided according to the gray value that cannot be tolerated. After processing the CT image, a model of the entire tooth can be obtained.

[0047] 2. After the tooth model is obtained, the tooth model needs to be divided into the same number of root and abutment integrated structures 1 or 2 and crown 3 according to the number of roots. The root of the integrated structure is used to implant the alveolar socket after the extraction of the affected tooth, which is responsible for fixing the entire tooth, and ...

Abstract

The invention discloses a multi-root implant tooth structure. The multi-root implant tooth structure is characterized by comprising a plurality of tooth root and abutment integrated structures, wherein the tooth root and abutment integrated structures are connected with one another. The bolt type assembled multi-root implant tooth structure is completely consistent with a multi-root tooth structure of a patient, and can be completely matched with a tooth socket after an affected tooth is pulled out, so that the clinical treatment process is simplified, the treatment cycle is greatly shortened, meanwhile, atrophy and collapse of soft tissues after tooth extraction can be effectively prevented, absorption of alveolar bones after tooth extraction is reduced, and the comfortable and beautiful effects of the patient can be improved. The bolt type assembled multi-root implant tooth structure is completely matched with the tooth socket of the patient, and has relatively high initial stability, so that an operator does not need to adopt a special implantation technology to increase the initial stability, the technical operation requirements on the operator and the infection risk of the postoperative patient can be greatly reduced, meanwhile, synostosis of an implant can be accelerated, and the implantation success rate is improved.

Description

technical field [0001] The invention belongs to the technical field of oral medical devices, and in particular relates to a multi-root dental implant structure and a manufacturing method thereof. Background technique [0002] With the improvement of the economic level and the maturity of implant technology, implant dentures are gradually accepted by more and more patients, and have become the most ideal restoration and retention method for patients with dentition defects and missing teeth. [0003] The current conventional implantation method is delayed implantation, usually 3-6 months after tooth extraction, that is, the implant is placed after the alveolar socket is completely healed, and then the upper part of the restoration is completed. Compared with delayed implantation, immediate implantation is to insert the implant into the alveolar socket at the same time as the tooth is extracted. Because it simplifies the clinical treatment process, has the advantages of short t...
