US Patent 11351011 Methods and systems for determining tooth structure

Methods, systems, and apparatuses are described for generating a digital model of a tooth structure for a gap between neighboring teeth of an arch form of a patient. Position of a tooth structure between neighboring teeth may be determined. Arch lines extending through the plurality of teeth may be determined. Intermediate points in the interdental gap may be determined. Longitudinal axis of the tooth structure relative to the neighbouring teeth may be derived. A digital model of the tooth structure may be aligned on the longitudinal axis and a digital model of the tooth structure may be obtained.
