Problems solved by technology

[0003] Among them, apical radiographs and curved body slices belong to two-dimensional imaging examinations, which have the advantages of low price and low radiation dose, but there are many disadvantages at the same time: 1. Two-dimensional images compress the shape of three-dimensional objects into two-dimensional On the image, the specific information of the implant implantation area cannot be completely and truly displayed; 2. The buccal and lingual width of the patient's alveolar ridge cannot be specifically evaluated by taking two-dimensional images before implant surgery, and the two-dimensional images taken after implant cannot evaluate the width of the implant. The relative position of the body in the buccal and lingual direction in the jaw; 3. Some studies have proved that there are torsion, deformation and magnification in the image of the conventional root tip and curved body slices
[0006] Therefore, most post-implant evaluations can only be based on two-dimensional images to analyze the orientation of the implant and its relationship with the adjacent teeth. Relative three-dimensional location of anatomical structures
At present, except for CBCT with high radiation dose, there is no tool that can obtain the three-dimensional position of the implant in the jaw after dental implantology

Abstract

The invention relates to an implant positioning method, device and equipment and a storage medium. The method comprises the following steps: step 1, matching first three-dimensional data of an implantwith scanning rod data to obtain second three-dimensional data, wherein the scanning rod data is three-dimensional data of a scanning rod; step 2, before a conventional implant implantation operation, performing CBCT shooting on the operation position, and obtaining medical image data; step 3, after the conventional implant implantation operation, inserting the scanning rod matched with the implant, and performing oral cavity scanning to obtain third three-dimensional data; step 4, registering the second three-dimensional data and the third three-dimensional data to obtain fourth three-dimensional data; and step 5, registering the medical image data and the fourth three-dimensional data to obtain the position of the implant in jawbone and the relationship between the implant and the surrounding anatomical structure, thereby achieving the technical effects of omitting the step of postoperative imaging examination and reducing the radiation exposure of a patient.
