Patent number: 11925435Abstract: An intra-oral scanning device includes a light source and an optical system, and communicates with a display system. The device provides for more efficient transmission and capture of images. It integrates OCT scanning with RGB-based scanning. In operation, the device is used for recording topological characteristics of teeth, dental impressions, or stone models by digital methods and for use in CAD/CAM of dental restorative prosthetic devices. To that end, the RGB-based scan obtains surface data (e.g., a margin), while the OCT scan penetrates the surface. The two scanners operate from within the same physical housing and preferably at the same time such that only one scanning pass (to obtain all necessary data) is required. The 3D data obtained from the OCT scan is registered with the 3D data obtained from the RGB-based scan by virtue of being captured using a common return path.Type: GrantFiled: June 9, 2022Date of Patent: March 12, 2024Assignee: D4D Technologies, LLCInventors: Ye Li, Justin G. Graham, Rod A. Duncan, Greg R. Basile, Grant E. Kenworthy, Henley S. Quadling, Mark S. Quadling, Glen Freeman

Patent number: 8532355Abstract: Methods, systems, and devices for generating textured 3D models are provided. The present disclosure describes methods, systems, and devices for combining multiple images onto a 3D model. In some instances, the textures of the images are applied to the 3D model dynamically so that the textured 3D model is viewable from different viewpoints in real time on a display. The present disclosure also describes methods, systems, and devices for selecting the images and, in particular, the portions of the selected images to map to defined portions of the 3D model. In addition, the present disclosure describes how to adjust the images themselves to remove the effects of directional lighting. Some aspects of the present disclosure are particularly useful in the context of a 3D modeling of dental preparations. In some instances, a 3D digitizer is used to produce 3D models of dental preparations.Type: GrantFiled: March 22, 2012Date of Patent: September 10, 2013Assignee: D4D Technologies, LLCInventors: Mark Quadling, Andrei Tchouprakov, Gary Severance, Glen Freeman
