Patent number: 10959817Abstract: A fixture plate includes a base having a contact face configured to support a dental model having a model identifier on a bottom surface. A bore extends through the base to one or more channels formed in the contact face and that extend from the bore. A viewing port extends through the base and has a transparent material inserted therein to seal the viewing port at the contact face. The viewing port and the transparent material enable the model identifier to be accessed from underneath the contact face when the dental model is on the contact face. A protrusion extends from the contact face and is configured to interface with an aperture of the dental model to retain the dental model in a specific orientation. The channels are configured to provide a suction force applied through the bore to hold the dental model against the contact face.Type: GrantFiled: August 14, 2019Date of Patent: March 30, 2021Assignee: SDC U.S. SmilePay SPVInventors: Josh Long, Christopher Yancey, Roland Harris, Chris Sorrells

Patent number: 10964121Abstract: Technologies for merging three-dimensional models of dental impressions include a computing device that generates multiple three-dimensional models that are each indicative of a dental impression of a user's dental arch. The models may be generated by scanning the dental impressions. The computing device determines whether a model is indicative of the complete anatomy of the user's arch and, if not, merges multiple models with a merge strategy to generate a merged model. The models may be merged by aligning geometry of the models, selecting geometry from one of the models using the merge strategy, and generating the merged model that includes the selected geometry. The merge strategy may include selecting from the model associated with the dental impression that includes the most detail of the user's anatomy or selecting from the model with the greatest depth.Type: GrantFiled: October 19, 2018Date of Patent: March 30, 2021Assignee: SDC U.S. SmilePay SPVInventors: Christopher Yancey, Josh Long
