Embodiment Construction

[0117] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0118] In related technologies, finite element is a highly complex method that requires professional technicians to preprocess the model, and at the same time, the calculation time often takes several hours and cannot be generated in real time. At the same time, the fine mesh data of the implant is also required, that is, although the finite element method can process the model, it often requires a long processing time and cannot meet the application scenarios with real-tim...

Abstract

The invention provides an implant safe area generation method and device, electronic equipment and a storage medium. The method comprises the following steps: obtaining an edge contour line of an implant along an axis profile, establishing a plane coordinate system, carrying out straight line fitting based on coordinates of pixel points on each curve in the edge contour line on a first quadrant of the plane coordinate system to obtain a plurality of fitting line segments, carrying out axial segmentation on the edge contour line to obtain a plurality of implant segments, determining implant parameters and safe area parameters corresponding to the plurality of implant segments, and generating a safe area image of the implant based on the safe area parameters corresponding to the plurality of implant segments. The planing surface analysis is directly carried out on the implant three-dimensional model, the thread type and the thread depth are approximately recognized, and the method is suitable for various implants and high in universality. The input data is less, the generated calculation amount is small, the calculation speed is high, and the influence area of the implanted spiral body on the surrounding tissue can be quickly calculated.

Description

technical field [0001] The invention relates to the technical field of dental implants, in particular to a method, device, electronic equipment and storage medium for generating a safe area of ​​an implant. Background technique [0002] Dental implants are a restoration method that uses metal implants to drive into the alveolar bone to replace the original missing teeth. It is well known that the teeth will be under pressure when occlusal, and the surrounding tissue will bear the reaction force after the pressure is transmitted to the implant. In order to ensure the firmness of the implant, the bone near the implant should have a certain strength. Influenced area, this area plays an important role in the selection of the length of the implant, the recommendation of the implant planning position, and the fully automated implant planning. [0003] In the related art, when calculating the impact area of ​​the implant screw on the surrounding tissue, there is no effective means...
