Publication number: 20250387205Abstract: Provided herein are systems and methods for determining if a 3D tooth model requires trimming or removal of incomplete or missing data (e.g., gingiva covering a portion of a tooth such as a molar). A patient's dentition may be scanned and/or segmented. Raw dental features, principal component analysis (PCA) features, and/or other features may be extracted and compared to those of other teeth, such as those obtained through automated machine learning systems. A classifier can identify and/or output probability that the 3D tooth model requires trimming. Trimming of the 3D tooth model can be implemented without human intervention.Type: ApplicationFiled: August 20, 2025Publication date: December 25, 2025Inventors: Roman A. ROSCHIN, Evgenii Vladimirovich KARNYGIN, Sergey GREBENKIN, Dmitry GUSKOV, Dmitrii ISCHEYKIN, Ivan POTAPENKO, Denis DURDIN, Roman GUDCHENKO, Vasily PARAKETSOV, Mikhail GORODILOV, Alexey VLADYKIN, Roman SOLOVYEV, Alexander BELIAEV, Elizaveta ULIANENKO, Leonid TROFIMOV, Anzhelika SON, Nikolay ZHIRNOV, Alexander VOVCHENKO

Patent number: 12419725Abstract: Provided herein are systems and methods for determining if a 3D tooth model requires trimming or removal of incomplete or missing data (e.g., gingiva covering a portion of a tooth such as a molar). A patient's dentition may be scanned and/or segmented. During dentition segmentation, a determination can be made whether trimming portions of the 3D model is desirable. A recommendation can be made for 3D model trimming based on the determination.Type: GrantFiled: June 5, 2024Date of Patent: September 23, 2025Assignee: Align Technology, Inc.Inventors: Roman A.

Publication number: 20250288394Abstract: Systems and methods for detecting missing or ectopic teeth. Methods may include accessing a digital model of a dental arch that includes tooth identifiers assigned to teeth of the dental arch based on tooth type. Methods may include detecting a missing or ectopic tooth in the digital model by identifying one or both of: a gap that exceeds a gap threshold between adjacent teeth of the dental arch, and tooth identifiers of adjacent teeth of the dental arch that do not match corresponding adjacent teeth of an ideal dental model. The methods may include re-assigning the tooth identifiers to the teeth of the digital model to account for the detected missing or ectopic tooth.Type: ApplicationFiled: May 13, 2025Publication date: September 18, 2025Inventors: Roman A. ROSCHIN, Evgenii Vladimirovich KARNYGIN, Sergey GREBENKIN, Alexey LAZAREV, Dmitry GUSKOV, Ivan SLEPYNIN, Alexey VLADYKIN, Alexander VOVCHENKO, Alexander BELIAEV

Patent number: 12329599Abstract: Methods for detecting missing or ectopic teeth. At least one tooth that is missing or ectopic may be detected in a dental arch by determining that a gap between adjacent teeth of a digital model of the dental arch exceeds a gap threshold. At least one tooth of the dental arch may be determined to be ectopic by performing an ectopic analysis of a region of the digital model of the dental arch above or below the gap. Anatomical identifiers may be assigned to the teeth of the digital model of the dental arch to account for the at least one tooth that is missing or ectopic. An orthodontic treatment plan to reposition one or more teeth of the dental arch using the assigned anatomical identifiers of the teeth of the digital model of the dental arch may be created.Type: GrantFiled: July 31, 2023Date of Patent: June 17, 2025Assignee: Align Technology, Inc.Inventors: Roman A.

Patent number: 12138137Abstract: A method for determining tooth numbers of teeth within a dental arch includes receiving a digital scan of a patient's dentition, detecting a cusp associated with at least one tooth in the digital scan, where the cusp is detected based at least in part on a radius of a surface of the cusp, matching a molar shape of the at least one tooth, and identifying the patient's molar tooth based on the molar shape.Type: GrantFiled: July 12, 2023Date of Patent: November 12, 2024Assignee: Align Technology, Inc.Inventors: Roman A.

Publication number: 20240293205Abstract: Provided herein are systems and methods for automatically segmenting a 3D model of a patient's teeth. A patient's dentition may be scanned. The scan data may be converted into a 3D model, including a sparse voxel representation of the 3D model. Features can be extracted from the sparse voxel representation of the 3D model and input into a machine learning model to train the machine learning model to segment the 3D model into individual dental components.Type: ApplicationFiled: January 5, 2024Publication date: September 5, 2024Inventors: Christopher E.

Patent number: 12036093Abstract: Provided herein are systems and methods for determining if a 3D tooth model requires trimming or removal of incomplete or missing data (e.g., gingiva covering a portion of a tooth such as a molar). A patient's dentition may be scanned and/or segmented. Features of the patient's teeth can be determined, including a tooth center point of at least three of the patient's teeth. The features of the patient's teeth are used to access a parametric model. A trim plane normal vector is identified for a distal tooth. Trimming of the 3D tooth model is based on the trim plane normal vector.Type: GrantFiled: April 13, 2023Date of Patent: July 16, 2024Assignee: Align Technology, Inc.Inventors: Roman A.
