A fully automatic planting guide plate production method

Abstract

A fully automatic implant guide plate production method, characterized in that: the following steps are adopted, step 1: respectively read the posture information of the oral cavity scan model, the dental arch curve, the implant and the retaining nail aligned with the CBCT image data, and set Guide plate selection boundary; Step 2: Carry out mesh hole filling and manifold pretreatment on the oral scan model; Step 3: Groove the surface of the scanned model; Step 4: Inner surface surface of the oral scan model mesh Expand a certain amount respectively to form the inner layer and the outer layer of the guide plate base, respectively select the corresponding guide plate areas on the inner layer and the outer layer through the set guide plate selection boundary, and splice the inner layer and the outer layer. At the same time, the The gap formed between the inner layer and the outer layer is automatically filled; the invention can quickly and efficiently generate guide plates. After the user inputs the required information, the entire process is fully automated, so the efficiency of guide plate generation can be greatly improved.

Description

technical field [0001] The invention relates to the field, in particular to a fully automatic method for producing a planting guide plate. Background technique [0002] Defect analysis of this technology in related products: [0003] Related dental implant software products involving implant guide generation: [0004] [0005] [0006] Defect summary: [0007] The current products have deficiencies in the smoothing of the edge of the guide plate and the processing of the grooves of the scanning grid, and most of the current guide plate design products do not have guide hole gaps, resulting in the need for a larger mouth opening for the patient during surgery, which increases the surgical cost. Uncomfortable, very few design software has the function of generating guide hole gaps, but it is necessary to manually adjust the direction of the guide hole gaps. [0008] Brief analysis of defects in related technologies (patents or papers): [0009] Patent name: A digital...

AI Technical Summary

Problems solved by technology

[0012] Disadvantages: The idea of ​​combining CBCT and scanning data to generate a planting guide plate is mainly proposed. The design of the guide plate is designed using ready-made design software, and the completed planting guide plate is not proposed.

[0015] Defects: The surface groove processing method based on voxel and spatial implicit function processing is proposed in this paper, which may easily reduce the overall grid resolution after groove processing, and at the same time, the computational complexity of voxel processing is high and the speed is slow

[0016] Summary of the above defects: the current implant guide plate generation technology lacks reliable surface groove processing technology and the automatic adjustment function of the guide hole gap. The edge of the resulting guide bar is not smooth enough, and the guide bar is less comfortable
