Abstract: Apparatuses and methods for assessing a dental x-ray image and predicting tooth eruption and/or exfoliation. The apparatuses may use one or more trained neural networks to assess a patient's x-rays as well as dental measurements determined from the patient's x-rays to predict approximately when a permanent tooth may erupt to replace a baby tooth. The neural networks may be trained using a data training set of x-ray images and accompanying dental measurement data.

Abstract: Methods and apparatuses (including software) for optimizing dental treatment plans, including for optimizing the treatment plans using dental aligners. These methods and apparatuses may optimize a treatment plan by estimating a difference between a target set of tooth position and a predicted set of tooth positions using the treatment plan using a prediction network trained to use multiple translational and rotational directions for individual teeth as well as reaction forces on the individual teeth based on adjacent teeth.
