Embodiment 1

[0067] Such as figure 1 As shown, a construction method of a virtual temporary abutment and its grinding guide plate, which is used in immediate restoration technology, includes the steps:

[0068] S1. Collect the patient's dentition data and export the STL format data, collect the patient's jaw CBCT data and export it as DICOM format data;

[0069] S2. Obtain the diagnostic wax-up based on the dentition data, fit the diagnostic wax-up with the CBCT data of the jaw, and perform virtual implant planning to obtain the implant data;

[0070] S3. Import the virtual implant planning results and dentition data into the reverse engineering software to construct geometric features, and obtain the virtual abutment through Boolean operations;

[0071] S4. Plane cutting the virtual abutment according to the diagnostic wax-up;

[0072] S5. Construct the prototype of the grinding guide plate based on the virtual temporary abutment, and cut the prototype of the grinding guide plate to obt...

Embodiment 2

[0100] The construction system of a virtual temporary abutment and its grinding guide provided in this embodiment is applied to the construction method of the virtual temporary abutment and its grinding guide of the previous embodiment, including:

[0101] Data acquisition module: collect the patient's dentition data and export the STL format data, collect the patient's jaw CBCT data and export it as DICOM format data;

Abstract

The present invention discloses a virtual temporary abutment and its construction method and system for adjusting grinding guides. Firstly, the patient's dentition data and jaw CBCT data are collected; the diagnostic wax-up is obtained and the jaw CBCT data is fitted, and virtual implant planning is performed. Obtain the implant data; import the virtual implant planning results and dentition data into the reverse engineering software to construct a virtual temporary abutment; cut the virtual abutment plane according to the diagnostic wax-up; build the grinding adjustment based on the cut virtual temporary abutment The prototype of the guide plate, and cut the prototype of the grinding guide plate to obtain the grinding guide plate for guiding the grinding of the finished temporary abutment, and finally 3D print out the grinding guide plate of the temporary abutment; the construction of the temporary abutment of the implant system is realized by the method of reverse construction of geometric features , breaking the limitations of existing software, enriching the content of preoperative digital design, and avoiding manual adjustment after traditional process pick-up, reducing the potential sensitization risk of fluid resin to individual patients.

Description

technical field [0001] The invention relates to the technical field of oral implantation, in particular to a construction method and system for a virtual temporary abutment and a grinding guide plate thereof. Background technique [0002] With the development and maturity of implant materials and designs, the initial stability of implants has been greatly improved, and the choice of restoration options has been expanded; when the implant insertion torque reaches 35Ncm, immediate restoration can be adopted, that is, in Connecting the temporary restoration immediately after the implant surgery can improve the aesthetic effect to a certain extent, especially in the aesthetic area of ​​the anterior teeth. At the same time, the immediate restoration is conducive to the preservation of the soft and hard tissues around the implant, which is beneficial to its long-term health. [0003] The existing literature mainly adopts the following methods to realize the fabrication of implant-...
