Embodiment 1

[0046] Such as figure 1As shown, this embodiment provides a multi-modal multi-angle dental implant registration method, including the following steps:

[0047] S1: Obtain the patient's oral cavity model; the model obtained in this step is a virtual three-dimensional model of the patient's oral cavity;

[0048] S2: Implant the implant model into the oral cavity model to obtain a preoperative 3D model;

[0049] S3: Obtain multi-angle oral cavity 2D pictures of the patient during operation;

[0050] S4: performing image registration on the 2D pictures of the oral cavity at different angles and the 3D model before operation;

[0051] S5: displaying the registration results of the oral 2D pictures from different angles and the preoperative 3D model.

[0052] It should be noted that, in the dental implant registration method provided in this embodiment, the patient's oral cavity model and the implanted implant model are obtained through steps S1 and S2, so as to construct a preop...

Embodiment 2

[0062] This embodiment is only further limited on the basis of Embodiment 1. This embodiment provides a multi-modal and multi-angle dental implant registration method, including the following steps:

[0063] S1: Obtain the patient's oral cavity model; the model obtained in this step is a virtual three-dimensional model of the patient's oral cavity;

[0064] S2: Implant the implant model into the oral cavity model to obtain a preoperative 3D model;

[0065] S3: Obtain multi-angle oral cavity 2D pictures of the patient during operation;

[0066] S4: performing image registration on the 2D pictures of the oral cavity at different angles and the 3D model before operation;

[0067] S5: displaying the registration results of the oral 2D pictures from different angles and the preoperative 3D model.

[0068] It should be noted that, in the dental implant registration method provided in this embodiment, the patient's oral cavity model and the implanted implant model are obtained thro...

Abstract

The invention provides a multi-mode multi-angle dental implant registration method, relates to the technical field of image registration, and is used for solving the problem that a dentist is difficult to judge the position deviation and angle deviation of an implant in an operation. The registration method provided by the invention comprises the following steps: S1, acquiring an oral cavity modelof a patient; S2, implanting an implant model into the oral cavity model to obtain a preoperative 3D model; S3, acquiring intraoperative oral cavity 2D images of the patient at multiple angles; S4, performing image registration on the oral cavity 2D images at different angles and the preoperative 3D model; and S5, displaying a registration result of the oral cavity 2D images at different angles and the preoperative 3D model. By the registration method provided by the invention, a doctor can visually observe the deviation between the implant position in the actual operation and the implant position preoperatively modeled in advance in the operation so as to guide and perfect the further surgical operation.

Description

technical field [0001] The present invention relates to the technical field of image registration, and more specifically, to a multi-modal and multi-angle dental implant registration method. Background technique [0002] Dental implant surgery refers to a method of edentulous restoration based on the underlying structure implanted in bone tissue to support and retain the upper tooth restoration. Through medical methods, the pure titanium metal with high compatibility with human bone is precisely designed and manufactured into cylinders or other shapes similar to tooth roots, and implanted into the alveolar bone in the edentulous area through minor surgical operations. After the artificial tooth root is closely bonded to the alveolar bone, a porcelain crown is made on the artificial tooth root. Dental implants have become the first choice for more and more patients with missing teeth. Because they are not destructive, dental implants have been recognized by the stomatology c...
