Embodiment Construction

[0030] Such as figure 1 As shown, the present invention provides a method for planning orthodontic accessories based on oral cavity voxel model extraction features, comprising the following steps:

[0031] S1. Prepare a training sample set, including the three-dimensional scanning results of individual teeth and the tooth attachment strategy given by the doctor, and perform corresponding data preprocessing.

[0032] S2. Design the orthodontic accessory planning strategy model, including the feature extraction module and the multi-label classification module in the deep neural network structure.

[0033] S3. Using the feature extraction module to obtain the global feature of the tooth point cloud.

[0034] S4. Combining the global features of the tooth point cloud extracted in step S3, the multi-label classification module is used to perform multi-classification to obtain the category information of the attachment on each tooth.

[0035] S5. Perform training according to the ...

Abstract

The invention relates to an orthodontic accessory planning method for extracting features based on an oral voxel model. The method comprises the following steps: for input three-dimensional tooth point cloud data, extracting tooth point cloud global features through a feature extraction module by using a deep neural network architecture, obtaining category information of attachments on each tooththrough a multi-label classification module, and training through two modes of independent training and packaging training; and inputting actually obtained three-dimensional tooth point cloud data byusing the trained deep neural network structure, and giving category information corresponding to appliance accessories needing to be bonded by individuals. The orthodontic accessory planning strategysuitable for the individual can be obtained according to the tooth characteristics, the implementation process is easy and convenient to operate, the deployment cost is low, an effective reference basis is provided for a doctor to plan a diagnosis and treatment scheme and design an appliance, and therefore the working efficiency of the doctor is improved, and the accessory selection accuracy is improved.

Description

technical field [0001] The invention relates to the field of orthodontics, in particular to an orthodontic accessory planning method based on feature extraction of an oral cavity voxel model. Background technique [0002] Orthodontics is to formulate corresponding orthodontic treatment plans for different deformities of teeth in different positions, and to use appropriate medical equipment (such as aligners) to apply a certain external force to the teeth to move the relative relationship of the teeth in the oral cavity and improve the oral occlusion Effects of state and morphology of dental deformities. [0003] During the orthodontic process, the doctor's technique (scheme design and clinical operation), the expression effect of the appliance, and the patient's cooperation are the three core elements that affect the effect of invisible orthodontic correction. The appliance attachment, as an important auxiliary device of the appliance, can not only strengthen the fit betwee...
