Problems solved by technology

[0005] In the existing technical solutions, the adjustment and grinding of natural teeth is too random, and because the natural teeth after adjustment and grinding are small in size, it is inconvenient for the operation of intraoral repositioning, and it is difficult to ensure the ideal position of the temporary restoration in the mouth; in addition, the above technical solutions all use With the pickup technology, the fluid resin monomer may be sensitized by direct contact with the tissue, and the temporary restoration may be contaminated by blood and saliva in the mouth, which is not conducive to infection control

Embodiment 1

[0056] A fixing device for temporary restoration of implants and a preparation method thereof, the fixing device includes a base and a bracket 5;

[0057] The base is provided with a tooth root accommodation cavity 2, an analogue body accommodation cavity 3 and a groove 4; the bracket 5 includes a positioning plate 51, and the positioning plate 51 is provided with a central channel that can pass through the abutment 7 of the implant 52, the positioning plate 51 is provided with a pillar 53 matching with the groove 4, wherein the structures of the base and the bracket 5 are respectively as follows figure 2 and image 3 shown.

[0058] The preparation process of the above-mentioned fixture is as follows, comprising the following steps:

[0059] S1. Obtain dentition data and diagnostic wax-up data, take CBCT to obtain jaw data, and perform virtual implant planning after fitting the diagnostic wax-up;

[0060] In this step, use an intraoral scanning device to collect digital i...

Embodiment 2

[0073] A composite structure for implant temporary restoration and a manufacturing method thereof, the composite structure is an implant-supported temporary restoration 8, and the implant-supported temporary restoration 8 includes an abutment 7 and a natural tooth 1;

[0074] The natural tooth 1 is obtained by opening a hole, truncating part of the tooth root, and grinding in sequence. The abutment 7 is fixed in the base through the substitute 6, and the abutment 7 is inserted into and fixed in the through hole in the natural tooth 1. The natural tooth 1 abuts with the abutment 7 at the abutment shoulder.

[0075] The preparation process of the above-mentioned composite structure is as follows:

[0076] The natural tooth 1 is drilled and ground in sequence by using the base and the bracket 5, and the natural tooth 1 after the grinding and drilling is connected with the abutment 7 to form an implant-supported temporary restoration 8, specifically:

[0077] The incisal end of t...

Abstract

The invention discloses a fixing device, a composite structure, and a manufacturing method for temporary restoration of implants. The manufacturing method includes the following steps: S1, acquiring dentition data and diagnostic wax-type data, taking CBCT to obtain jawbone data; S2, extracting target natural teeth STL data of the implant, dentition and target natural teeth, extract the implant neck platform plane, and generate the abutment shoulder plane after offsetting a specific distance; S4, generate based on the abutment shoulder plane Base; S5, generate a bracket that matches the base; S6, 3D print the base and bracket; S7, use the base and bracket to drill holes in the natural teeth in turn, adjust the grinding, and connect the natural teeth after the adjustment and drilling to the abutment to form Implant-supported temporary restorations. Through the manufacturing method of the present invention, the natural tooth after adjustment and grinding has good adaptability to the selected implant, and there is no need to use fluid resin monomers.

Description

technical field [0001] The invention relates to the technical field of dental implants, in particular to a fixing device, a composite structure and a manufacturing method for temporary restoration of implants. Background technique [0002] When the natural tooth has no preservation value due to trauma or treatment failure, and there is a complete alveolar bone wall on the labial side, the implant can be completed while the natural tooth is extracted. When the implantation torque is ≥35 Ncm, immediate restoration can be considered, that is, partial aesthetics and pronunciation function can be restored through a fixed temporary restoration supported by the implant. [0003] Generally speaking, implant-supported temporary restorations are made of methacrylic resin materials. The methods reported in the literature mainly include the following three methods: ① Preoperative cutting or printing of polymethylmethacrylate (PMMA) shells, surgery After completion, connect the temporar...
