Publication number: 20210393376Abstract: Attachments for tooth movements are described herein where the orthodontic attachments may be formed by obtaining a digital model of a dentition of a subject and digitally placing one or more attachments upon the digital model for imparting one or more preselected movements to the dentition. A finite element model may be formed with one or more forces applied to the dentition and an initial stress map may be created to impart upon the dentition based on the finite element model. A subsequent stress map may be predicted using, e.g., machine learning, to achieve the one or more preselected movements.Type: ApplicationFiled: August 31, 2021Publication date: December 23, 2021Applicant: uLab Systems, Inc.Inventors: Eric WU, Louis SCHUELLER, Surya SARVA, Henry CAO
