Systems and methods for constructing a three-dimensional model from two-dimensional images

A system comprising:

• a model generation system configured to:
• receive one or more first images of a first dental impression of a dental arch of a user;
• generate a first three-dimensional (3D) model of the dental arch of the user by applying the one or more first images to a machine learning model trained to generate 3D models of dental arches from two-dimensional (2D) images of dental impressions of the dental arches;
• receive one or more second images, wherein the one or more second images are of one of the first dental impression of the dental arch or a second dental impression of the dental arch;
• and
• generate a second 3D model of the dental arch of the user by applying the one or more second images to the machine learning model;
• and
• a model merging system configured to:
• merge the first 3D model and the second 3D model to generate a merged model.

A method comprising:

• providing, by a model training system, a machine learning model using one or more training images of a dental impression of a respective dental arch and a three-dimensional (3D) training model of the respective dental arch;
• receiving, by a model generation system, one or more first images of a first dental impression of a dental arch of a user;
• generating, by the model generation system, a first 3D model of the dental arch of the user by applying the one or more first images to the machine learning model;
• receiving, by the model generation system, one or more second images, wherein the one or more second images are of one of the first dental impression of the dental arch or a second dental impression of the dental arch;
• generating, by the model generation system, a second 3D model of the dental arch of the user by applying the one or more second images to the machine learning model;
• and
• merging, by a model merging system, the first 3D model and the second 3D model to generate a merged model of the dental arch of the user.

A system comprising:

• a model training system configured to:
• receive a plurality of data packets of a training set, each data packet of the plurality of data packets including data corresponding to one or more training images of a dental impression of a respective dental arch and a three-dimensional (3D) training model of the respective dental arch;
• identify, for each data packet of the plurality of data packets of the training set, a plurality of correlation points between the one or more training images and the 3D training model of the respective dental arch;
• and
• generate a machine learning model using the one or more training images, the 3D training model, and the plurality of correlation points between the one or more training images and the 3D training model of each data packet of the plurality of data packets of the training set;
• and
• a model generation system configured to:
• receive one or more images of a dental impression of a dental arch of a user;
• and
• generate a 3D model of the dental impression of the dental arch by applying the one or more images of the dental impression to the machine learning model.
