Abstract: Systems and techniques for comparing orthodontic setups are disclosed. The method involves receiving an instant orthodontic setup and a reference orthodontic setup, both comprising three-dimensional (3D) representations of one or more teeth. The processing circuitry compares at least one aspect of the instant orthodontic setup with the corresponding aspect of the reference orthodontic setup to compute a comparison metric. The comparison metric represents the degree of similarity or dissimilarity between the two setups. The processing circuitry then outputs the computed comparison metric. These systems and techniques enable efficient and accurate comparison of orthodontic setups, aiding in the evaluation and assessment of treatment plans and facilitating informed decision-making in orthodontic procedures.

Abstract: Systems and techniques are disclosed for generating setups for orthodontic alignment treatment. The method involves receiving a digital representation of a patient's teeth and at least one value pertaining to the customization of orthodontic treatment. A prediction for one or more tooth movements for a setup is formed by executing a generator network comprising one or more neural networks. The generator network is further trained based on the formed prediction by performing operations that include predicting the tooth movements, quantifying the difference between the predicted tooth movements and reference tooth movements, generating a loss value based on the quantified difference, and modifying the generator network based on the loss value to form a modified generator network. These systems and techniques enable the efficient generation of setups for orthodontic alignment treatment, improving the accuracy and customization of the treatment process.

Abstract: Systems and techniques for encoding and reconstructing three-dimensional (3D) representations of oral care data are disclosed. The method involves receiving an input 3D representation of oral care data and utilizing the processing circuitry to execute an encoder of a trained autoencoder network. The encoder encodes the input 3D representation into a latent space representation with a lower dimensionality. Subsequently, the processing circuitry executes a decoder of the trained autoencoder network to reconstruct the latent space representation, generating an output 3D representation that closely resembles the original input. To quantify the accuracy of the reconstruction, the processing circuitry computes a reconstruction error, which measures the difference between at least one mesh element of the input 3D representation and the corresponding mesh element of the output 3D representation.

Abstract: Systems and techniques for classifying a 3D representation of oral care data are disclosed. The method involves receiving a first 3D representation comprising one or more mesh elements and providing it as input to a trained autoencoder network. The processing circuitry computes one or more mesh element features for the mesh elements and provides them to the trained autoencoder network. By executing the trained autoencoder network, the first 3D representation of oral care data is encoded into one or more latent space representations. These latent space representations are specifically designed for utilization by a machine learning model for the classification of the first 3D representation of oral care data. These systems and techniques enable accurate and efficient classification of 3D representations, enhancing the analysis and understanding of oral care data for improved diagnosis and treatment planning.

Abstract: Systems and techniques are disclosed for generating and transferring pose information in three-dimensional (3D) representations of oral care data. The method involves receiving reference 3D representations and trial 3D representations of oral care data using processing circuitry of a computing device. Pose transfer neural networks are executed to assign pose information from the reference 3D representations onto the trial 3D representations. By incorporating the assigned pose information, one or more resulting 3D representations of oral care data are generated, wherein aspects of the trial 3D representations are modified to generate the resulting 3D representations. These resulting 3D representations, enriched with pose information, are then provided to one or more automated processes. These systems and techniques enable accurate and efficient analysis of oral care data, facilitating improved treatment planning and decision-making in the field of oral healthcare.

Abstract: Systems and methods are disclosed for generating a three-dimensional (3D) representation of oral care data for use in oral care treatment. The systems and methods involve receiving an input 3D representation of a patient's dentition and encoding the 3D representation into a lower-dimensional first latent representation using a trained first machine learning (ML) module. Subsequently, a trained second ML module, comprising a trained transformer encoder model or a trained transformer decoder model, is executed to generate a second latent representation using the first latent representation. The second latent representation is then reconstructed into a 3D oral care representation (e.g., a tooth restoration design, an appliance component, a fixture model component, etc.) by a decoder. Finally, the processing circuitry outputs the reconstructed 3D representation of oral care data.

Abstract: Systems and technique are disclosed for generating transforms and oral care appliances for oral care treatment. The method involves receiving a first three-dimensional (3D) representation of oral care data and utilizing processing circuitry to execute a machine learning (ML) model that includes at least one transformer. The ML model generates at least one transform based on the input data. The processing circuitry applies the generated transform to the first 3D representation, placing it in a desired pose relative to a second 3D representation or a global coordinate system axis. Based on this application, the method further generates aspects of one or more oral care appliances associated with either the first 3D representation or the second 3D representation. These systems and techniques enable the efficient generation of transforms and oral care appliances, facilitating improved treatment planning and customization in oral care applications.
