Patent number: 11419700Abstract: A computer-implemented method for marking an object on an aligner. The aligner surface is modeled. The method includes calculating a normal for each tile in a tessellated surface and disqualifying a tile from being selected. For tiles not disqualified, a patch is identified that produces a markable area. The method includes selecting an object to be marked, calculating a location of the object in the markable area, and providing the location of the object to a marking device. Disqualifying includes comparing an angle between a normal and an orientation of the beam to an origin of the calculated normal on each tile. Disqualifying includes disqualifying the at least one tile when the angle is outside of a range of ?90° to +90°. Identifying the patch includes separating the patch into at least two smaller patches, and one of the two smaller patches of tiles is the markable area.Type: GrantFiled: March 22, 2019Date of Patent: August 23, 2022Assignee: Ormco CorporationInventors: Mithil J.

Patent number: 11045281Abstract: The invention generally relates to methods, systems, and computer program products for digital orthodontic setup using a prescribed ideal arch form. The invention may include an imaging system, an orthodontic device production system, and an orthodontic treatment system interconnected by way of a network. The orthodontic treatment system may facilitate manipulating one or more reference teeth into a position by the dental practitioner. The orthodontic treatment system may further facilitate selection of an ideal unit-less arch form and scaling of the ideal unit-less arch form into a scaled ideal arch form to fit the reference teeth. After the selected ideal unit-less arch form is scaled to fit the reference teeth, the remaining teeth are positioned with respect to the scaled ideal arch form, either manually by a dental practitioner or automatically by an alignment algorithm.Type: GrantFiled: April 21, 2017Date of Patent: June 29, 2021Assignee: Ormco CorporationInventors: Evan Yifeng Tsai, Ian Kitching

Patent number: 11033361Abstract: Methods for orthodontic treatment planning include modifying a digital picture of a patient based on a tooth model produced during simulated orthodontic treatment after movement of at least one model tooth to produce a modified digital image depicting the at least one model tooth after movement. The method includes matching and morphing information from the digital picture into the modified digital image. Modifying includes matching a model tooth in the T1 model to a tooth in the digital picture and morphing that information into the modified digital image. Morphing may include projecting a model tooth in the T1 model to an image plane of the digital picture and projecting a model tooth from an intermediate T model to the image plane. Parameterization of the projections of each model may be used to develop a pixel correspondence map, which is usable during rendering of a tooth in the modified digital image.Type: GrantFiled: October 19, 2018Date of Patent: June 15, 2021Assignee: Ormco CorporationInventors: Evan Yifeng Tsai, Bindu Saran A.
